Title: Method and system for rapid power exchange

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is a continuation of U.S. Ser. No. 15/812,906, which in turn claims benefit of U.S. Provisional Application No. 62/421,764, filed Nov. 14, 2016, all herein incorporated by reference. 
    
    
     FIELD OF INVENTION 
     The present invention relates to a method and system for exchanging a power source which includes but is not limited to replacing, i.e. exchanging, one power supply such as a battery for another. Advantageously, this includes the exchange of the power source of an electric vehicle. 
     BACKGROUND OF THE INVENTION 
     Alternative fuel vehicles are becoming increasingly popular. Such vehicles use alternative fuel sources rather than conventional petroleum such as gasoline and diesel. Some alternative fuel sources include but are not limited to natural gas, battery/chemical-electrical source, fuel cell, etc. As with conventional vehicles, one must replenish the fuel source consumed by the vehicle. This has resulted in the development of various refueling, recharging, regeneration or other means for replenishing the fuel source for the alternative fueled vehicle. 
     Alternative fuel vehicles which are powered by battery in many instances are recharged by plugging the vehicle into a suitable recharging receptacle which recharges the batteries on-board the vehicle. One alternative to this method is to replace the battery packs on the vehicle after they have been depleted with fully charged batteries. However, current technologies for accomplishing alternative powered vehicle battery replacements in the field requires significant infrastructure in terms of a facility to accommodate the vehicle during a battery exchange and the mechanism necessary to accomplish a replacement of a series of depleted batteries with replacement ones that are charged. Accordingly, such systems are not economically feasible and/or developed at a stage which allow for real-time battery replacement as a means of replenishing an alternative powered vehicle every time its battery is depleted. 
     One most recent advancement in accommodating alternative fuel vehicles is provided in Applicant&#39;s co-pending International Patent Application PCT/US16/29011 (011) filed Apr. 22, 2016, herein incorporated by reference, directed to a technology known as Autonomous Linear Exchange (ALE) which uses a unique method and system for removing, receiving, charging, deploying and replacing a vehicle&#39;s main power source, including a power source disposed in a container, (in which the container includes a power source such as a battery bank, fuel cell, or other stored power device collectively referred to as “power source”), of an auxiliary powered exchange equipped vehicle. In the &#39;011 method and system, a suitably equipped vehicle has a lift mechanism deployed on-board the vehicle for removing a container with depleted power source and inserting a container with charged power source. 
     SUMMARY OF THE INVENTION 
     The present technology is directed to an advancement or alternative to the &#39;011 method and system. In the present method and system for power exchange, a mechanism for removing a container with depleted power source and inserting a container with charged power source is provided on the ground of a suitable power exchange location, mounted to a power exchange terminal, rather than being on-board the vehicle itself as in the &#39;011 method and system. The present mechanism operates similar to the one in the &#39;011 system. Accordingly, this disclosure highlights the differences in the present method and system. Items that operate similarly are therefore not discussed in detail in this disclosure as that disclosure has been incorporated by references in this disclosure. 
     The lift present mechanism and power exchange terminal can be installed at ground level such as a concrete surface, having a sufficiently low profile to allow a vehicle to drive over the lift, container and terminal. Accordingly, the present method and system does not require the lift mechanism and power exchange terminal to be deployed underground, embedded within the ground or require breaking ground to accommodate the placement and operation of the lift and terminal. 
     More specifically the technology of this disclosure can be used to exchange the main power source, e.g. drive batteries of an electric powered vehicle which are disposed in a container or other replaceable unit. However, this technology can be adapted for use of exchanging any power source including various types of power sources which are used by vehicles including electric vehicles. The present invention pertains to both stationary equipment designed to receive, charge, organize, and deploy said power sources, batteries or fuel cells with extreme efficiency and simplicity, as well as componentry and a modular container intended for incorporation into automotive designs, which enable the vehicle to interact with the stationary equipment. 
     In one advantageous form, a suitable vehicle has a battery bank, battery pack, power pack, cell(s), including fuel cells, etc., (collectively generically referred to as a “power source” which may include one or more cells or discrete power units) self-contained in what is referred to in this disclosure as a “container”. This container also includes, in an advantageous embodiment, a cooler and the container may also include other elements which allow the container to be a self-contained, removable power source, which provides main drive system power to the vehicle. It is this container which is exchanged when depleted of power for one charged with power, using the present system. 
     Further, in addition to the container which is the main power source for the vehicle, the vehicle will advantageously also have an auxiliary power source, apart from the container with main power source, which assists during the container exchange. The auxiliary power source powers movement of the vehicle from a first terminal to a second terminal, after the depleted main power source has been removed from the vehicle. The auxiliary power source is normally recharged by regenerative braking and by the main power source. However, both the main power source (in the container) and the auxiliary power source (permanently mounted in the vehicle) can also be recharged (as an option if desired by the manufacturer) by plugging the vehicle into a suitable recharging outlet/source. 
     The present invention in one form thereof, relates to a system for vehicle power exchange. This system has at least one power exchange terminal. The power exchange terminal is dispensable on a ground surface. The power exchange terminal has a sufficiently low profile such that when disposed on a vehicle driving surface, a vehicle for power exchange can drive over the power exchange terminal during power exchange. The power exchange terminal has at least a drop mechanism or a lift mechanism. The drop mechanism is associated with the at least one exchange terminal for releasing a depleted power cell from a vehicle during its power exchange. The lift mechanism is associated with the at least one power exchange terminal for inserting a charged power cell into the vehicle during power exchange. 
     In one further advantageous form of the system, the at least one power exchange terminal comprises at least two power exchange terminals, a first one of the at least two terminals comprises the drop mechanism and the second one of the at least two terminals comprises the lift mechanism. 
     In a further advantageous form, the system comprises two or more power exchange strips and the power exchange strips form a power exchange facility for vehicle power exchange. For example, the power exchange strips can be arranged in an array of power exchange terminals. 
     The present invention, in another form thereof, relates to a method for vehicle power exchange. The method includes receiving a vehicle power exchange at a first position along a power exchange strip and removing a depleted power cell from the vehicle by releasing the power cell from the vehicle at the first position. Next, the vehicle is received at a second position along the power exchange strip. Finally, a replacement power cell is inserted into the vehicle at the second position. 
     The present invention, in another form thereof, relates to a system for vehicle power exchange. The system has at least one power exchange terminal and at least one container having a power source and being associated with the power exchange terminal. A wireless communication device is operatively associated with the power exchange terminal for communicating between the power exchange terminal and a vehicle requesting power exchange. A processor is associated with the power exchange terminal and the wireless communication device for controlling and coordinating functions of the vehicle requesting power exchange. This processor can be mounted in the vehicle or the power exchange terminal. 
     In a further form, the power exchange terminal of the present invention will also contain a powered lift mechanism. In such an advantageous form the lift mechanism can be activated, when called upon by the processor via the communication connection, to raise and lower the main power source container. In doing so, and if the vehicle is in position directly over the power exchange terminal, the lift mechanism can remove a container having a depleted main power source from the vehicle. Likewise, the lift mechanism, which is mounted to the power exchange terminal can also insert a container having a charged main power source into the vehicle. 
     The power exchange terminal, of the present invention, will additionally contain a port which matches a port on the container to which the power exchange terminal is associated. Such a port may be in the form of an electrical connector containing conductive contact points, a device for transferring compressed fuel, or other coupling which permits the transfer of power or fuel from the power exchange terminal to the container, and from the container to the power exchange terminal. Thus, a two-way connection is achieved and the bi-directional flow of power or fuel is uninhibited. 
     In one further form, at least two power exchange terminals can be placed adjoining length-wise to form a power exchange strip. The power exchange strip then has one terminal for receiving a depleted container with power source from a vehicle requesting power exchange, and at least one additional terminal which has a replacement container with charged power source for installation of the container into the vehicle after the depleted container has been removed. 
     In one further advantageous form, a processor and wireless connection control movement of the vehicle between the first station and the second station. 
     In alternative forms, depending on the vehicle, the power source employed is a chemical battery pack or fuel cell pack, compressed gas or other rechargeable or refillable source of power. 
     The present invention, in another form thereof, relates to an on-board vehicle system for power exchange. The on-board vehicle system has a removable container with a main power source for primarily powering movement of the vehicle. A computer processor is associated with the vehicle for controlling requisite functions of the vehicle during power exchange including releasing a depleted container, movement of the vehicle after the depleted power pack has been removed and insertion of a replacement container with charged or filled power source into the vehicle. A locking mechanism is associated with the computer processor for securing a container to the vehicle and releasing a container from the vehicle. Feedback sending units and vehicle control hardware are also operatively associated with the computer processor for controlling the vehicle&#39;s movements through the power exchange sequence, and harmonizing the activation of the lift on the power exchange terminal to execute the removal or replacement of a power source container. 
     The present invention, in another form thereof, relates to a method for vehicle power exchange. The method includes receiving a vehicle for power exchange at a first position at the entrance of a power exchange strip and establishing a wireless communication connection between the vehicle and the power exchange strip to control vehicle function and power exchange terminal function during power exchange. The method further includes communicating instructions to a computer processor of the vehicle via the wireless communication connection to release a container with depleted power source from the vehicle at the first position along the power exchange strip. The vehicle is then moved to a second position along the power exchange strip. Finally, a replacement container with charged power source is inserted into the vehicle, in which the replacement container is associated at the second position of the power exchange strip. The method in a further form includes moving the vehicle to a second position along the power exchange strip, using auxiliary power on-board the vehicle, supplemental to the power of the removed main power source. 
     In one further form, the processor activates a lift mechanism via the communication connection and releases locks securing the container to the vehicle at the first position along the power exchange strip, resulting in the vehicle releasing the container having depleted main power source. 
     The present method in a further form includes inserting a container with charged main power source, associated with the second position of the power exchange strip, into the vehicle by activating the lift mechanism associated with the second position. In one further advantageous form, the lift mechanism is incorporated into the power exchange terminal. 
     In use, a compatible vehicle approaches an entrance to a power exchange strip, at a predetermined range, the vehicle will automatically establish wireless communication with the terminals, come to a stop, and normal driving control will be suspended. At this point wireless communication from a remote server will provide instructions to the vehicle&#39;s on-board processor concerning which terminals along the power exchange strip to stop over and interact with. Once instructions are received, the vehicle&#39;s autonomous control system engages and drives the vehicle to a precise position over the instructed empty terminal requiring no human interaction. The vehicle then switches to its on-board auxiliary power source, and activates the lift mechanism of the power exchange terminal, via wireless communication, to raise and make contact with the container having depleted main power source. The processor then releases the locks which secure the container to the vehicle, and again activates the lift mechanism on the terminal to lower the container with depleted main power source to a low resting position below the vehicle, allowing the vehicle to freely pass over the terminal and container. The vehicle then moves under auxiliary power, guided by wireless and optical cues on the charge strip, to the terminal holding the replacement container designated by the provided instructions. The processor then, via the communication connection, activates the lift mechanism on the designated terminal having charged power source to lift the container to the riding position of the vehicle. Locks then secure the container to the vehicle, and the processor activates the lift of the power exchange terminal once again to retract it away from the vehicle and the secured container to a low resting position. The vehicle then switches from auxiliary power to the charged main power source and proceeds under autonomous control to the exit of the power exchange strip. As the vehicle passes over the very end of the strip it comes to a stop automatically, suspends autonomous control, and reinstates normal control. The vehicle is then able to proceed from the strip under normal control with a container having charged main power source, while leaving the container with depleted main power source on the strip for charging.

     DESCRIPTION OF THE STATIONARY ALE EQUIPMENT 
     Referring now to the Figures and in particular  FIGS. 1-4 , in one exemplary form, autonomous linear exchange (ALE) of the present technology such as the system  10  may be used to exchange a container  17  having a depleted power source (i.e. container  17   a  of vehicle  30  in which the power source is depleted,  FIGS. 3 and 4 ), with a container having charged power source (e.g. containers  17   b  and  17   c ,  FIGS. 3 and 4 ) of a suitably configured vehicle such as electric vehicle  30 . Compatible vehicles such as vehicle  30  will possess distinctive attributes (e.g., see discussion to follow) that enable ALE and thus the use of the stationary equipment hereafter referred to as the strip  12 . The strip  12  consists of at least two low profile power exchange terminals  12   a ,  12   b ,  12   c  placed in series with at least one terminal  12   a  empty for receiving a container with a depleted power source. The strip  12  is modular, allowing its length and, thereby its capacity of containers  17  (both with charged power source and depleted power source), to easily be increased or decreased by adding or subtracting supplementary terminals  12   a ,  12   b ,  12   c  to or from the strip  12 . 
     A lift mechanism is incorporated into the design of the power exchange terminal  12   a ,  12   b ,  12   c  having a boom  120  with a pivot point  121  at the proximal end (where it is mounted to the terminal base  124 ) and tip  122  compatible with a contact point  131  on the under-side of the container  17  associated with the terminal  12   a ,  12   b ,  12   c  at the distal end. This boom  120  is raised and lowered by an actuator or ram  123  positioned between the boom  120  and the base of the terminal base  124 . The ram or actuator  123  is activated by commands received from the vehicle&#39;s on-board processor and in coordination with the power exchange sequence. The boom  120  of the lift mechanism is very low profile, and partially tucks into a groove  132  ( FIG. 7 ) on the under-side of the container  17  at the low resting position so both container  17  and the boom  120  beneath it can be driven completely over by the vehicle  30  executing power exchange. The boom  120  of the terminal&#39;s lift mechanism is also marked with optical cues and other stationary guidance signals which aid in the autonomous operation of the vehicle making power exchange. The boom  120  and boom-tip  122  at the distal end are very simple yet maintain perfect control of the container  17  due to a two-stage lifting process (explained below). 
     In one further form, electrical contacts  133  near the boom-tip  122  of the lift mechanism are utilized to establish a two-way power connection between the power source of container  17  and the charger or supply on the terminal  12   a ,  12   b ,  12   c  side for recharging the power source in the container  17 . This single point of necessary contact allows for the widest range of container  17  sizes and shapes possible, and thus will place very little limitation on automotive design. A charger and or a hydraulic pump can be fitted within the terminal base  124  otherwise the terminal  12   a ,  12   b ,  12   c  can be remotely operated via electrical extension cables and hydraulic hoses, or even kinetic control systems. Due to these versatilities, and the simplicity of terminal  12   a ,  12   b ,  12   c , and thus strip  12  design, the system requires no ground-breaking, and can be assembled or removed from a site in hours. This is a key point of engineering as it allows maximum infrastructure scalability due to reduced cost and liability. 
     One significance of the present configuration is that a container  17  having a power source can be positioned by the vehicle  30  under auxiliary power, placed onto the appropriate terminal  12   a ,  12   b ,  12   c , and then be driven completely over, straddled by the vehicle  30 &#39;s left-side and right-side tires. 
     In one alternative, specific form, ramps or recessed pavement  7  will be necessary to provide adequate clearance between the power exchange terminal and vehicle during power exchange. 
     Since the ALE system  10  is linear, with terminals spaced to create a line of containers  17  (containers  17   b  and  17   c  in  FIGS. 1-4 ) end to end, vehicles  30  are able to drive over the strip  12  and the row of containers  17  (e.g. containers  17   b ,  17   c ) which eliminates the need for expensive stationary robotic automation for exchanging and organizing the containers  17 . This will be more apparent in the discussion to follow with reference to  FIG. 3 . 
     A core understanding is that the ALE equipped vehicle  30  itself replaces expensive and complicated stationary equipment which some prior known technologies may deploy. The vehicle  30  is then able to deposit a container  17  (e.g. container  17   a ) with depleted power source on an empty terminal  12   a ,  12   b ,  12   c  of the strip  12  for charging or fueling the depleted power source. The vehicle  30  can then move forward or backward using an auxiliary power source (e.g.  16   a ,  16   b ) while straddling the line of containers  17 , disposed on the strip  12 . Finally, the vehicle  30  positions itself over a terminal and container designated by the instructions, and retrieves a container  17  (e.g. container  17   b ) with charged power source. The strip  12  also contains a short range wireless communication system, guidance markings, and processor which it uses to gather information from the containers  17 , guide the vehicle  30  under autonomous control and execute the container  17  exchange. 
     Description of the Mobile (in Vehicle) ALE Equipment 
     In order to be compatible with ALE, as discussed above, a vehicle such as vehicle  30  must be able to move and perform robotic functions using an on-board auxiliary power source (e.g.  16   a ,  16   b ) that is electrically connected to the drive system when the container  17  with main power source is disconnected from the drive system and removed from the vehicle  30 . 
     This auxiliary power source (e.g.  16   a  and  16   b  of  FIG. 6 ) need not be large or bulky because the energy required to move the vehicle  30  along the strip once the main power source (i.e. the vehicle&#39;s container  17 ) is disconnected is minimal. The standard method of charging the auxiliary power source, which does not leave the vehicle, is through the energy created via regenerative braking, however other methods can also be employed. Using this method wastes no energy from the main power source and instead charges the auxiliary power source each time the brakes of the vehicle are applied during normal use. 
     Advantageously, vehicle  30  is equipped with compatible autonomous control equipment and a computer which is able to receive and process information from the strip  12  via wireless and optical cues. From these instructions, ALE logic stored within the computer will respond by activating the installed autonomous control equipment and the vehicle  30 &#39;s motor controller to move the vehicle  30  forward or backward along the strip  12 , stopping over the appropriate terminals  12   a ,  12   b ,  12   c  per the instructions, and steering to keep the vehicle tracking perfectly over the linear strip  12 . In addition to these communicative and autonomous features, the vehicle  30  must be further equipped with a locking system  134  ( 11   a ,  11   b  of  FIGS. 13-16 ) which is able to secure and release the container  17  from the vehicle  30  at the appropriate positions along the strip  12  and in coordination with the provided instructions. If the vehicle  30  was not designed to be compatible with ALE, a sub-frame can be prepared in many cases, given that adequate ground clearance can be achieved, and fitted to the vehicle  30  in order to adapt it to be compatible with ALE. 
     Referring now to  FIGS. 5 and 6 , though it is not intended to be perceived in any way as a limitation to this technology, it has been determined that a flat, rectangular container  17  situated within the wheelbase of the vehicle  30  at the lowest point possible is best practice for ALE designs. Such a configuration allows for a minimally invasive container  17  that is best positioned to perform an ALE exchange. 
     Description of the ALE Modular Power Source Container 
     Referring now to  FIGS. 7 and 8 , the ALE container  17  consists of several key sub-components that distinguish it from non-ALE containers, and is designed to be as low profile, light, and as close to a basic flat rectangle as possible. Most applications will require some or all of the corners of the flat rectangular shape to be chamfered  14  in order to allow adequate clearance for accommodating steering wheels (now shown). 
     The architecture of the container  17  is designed around a structural “spine”  15 , consisting of a channel which provides longitudinal rigidity, as well as provides structural bites  18   a ,  18   b  at each end for reception of the front and rear main locks  134   a ,  134   b  of vehicle  30  (see  FIGS. 5 and 6 ). The spine  15  also provides a passage and protection for the electrical buss  20  that runs the length of the container  17  and connects the power source modules to front  21   a , center  131  and rear  21   b  electrical contact points. This allows automakers to tap into the front, or rear of the container for drive power as well as additional charging options. The central electrical contact has a depressible protective cover  131   a , that when depressed from below by the terminal  120 &#39;s boom-tip  122 , reveals the electrical contact points which then match contacts near the boom&#39;s distal end. These contacts are connected while the container  17  is on the terminal  12   a ,  12   b ,  12   c  in the low resting position. The electrical buss also contains the data collection and storage module  22  which collects data from sensors throughout the container and then sends the data to the ALE Control Center as will be discussed more in the disclosure to follow. 
     Referring now to  FIGS. 7-11   a , the spine  15 , of this particular example, also houses an oil cooler  9  for the container  17 . The oil cooler area is usually centered and located within the spine  15  of the container  17 , but can be located anywhere within the container  17 . The cooler  9 , like the container  17  itself, is modular consisting of a number of cores  9   a - 9   d . Each core  9   a - 9   d  consists of a small mineral oil-resistant radiator  23  and micro-pump  24 , mounted to a size-matched electric fan  25 .  FIGS. 10 a  and 11 a    show a discrete core  9   a  to more clearly emphasize that the cooler  9  is in fact composed of cores  9   a - 9   d , and thus cores  9   a - 9   d  can be added or subtracted to increase or decrease cooling consistent with the application of the container  17 . 
     Cooler  9  size is matched to average usage of the style of container  17 . For instance, a style-A container  17  might have a standard six-core cooler  9 , and a style-A-HP (high performance) might have a 12-core cooler  9  to support a higher power consumption rate. The cooler  9 &#39;s radiators  23  are plumbed into inlet and outlet ports  23   a ,  23   b  usually located on the spine  15  channel ears  15   e  which lead into the container  17 &#39;s left and right side “wings”  26 , and mineral oil or similar non-conductive coolant is able to flow either using an open-circulatory system, or a closed-circulatory system via the small inline pump  24 , across the radiator  23 , and into the wings  26  containing the power source. 
     The container  17  framework also includes a perimeter channel  27 , with ears facing inboard  27   e  which acts as secondary structure to the main spine  15 , and also provides protection for the container  17 &#39;s contents from a side impact. The container  17  is skinned on top with a lightweight water and oil resistant material, a lid  28 , with an oil-tight seal. It is also an advantageous adaption to skin the top of the pack with photo-voltaic panels for power source charge maintenance while lying on the strip  12 . The lid  28  also bares color and shape markings along the upper surface and centered along the center-line of the container  17  similar to that of the strip  12 , so that vehicles  30  passing over the container  17  while it is lying on the strip  12  are able to maintain alignment via visual cues. The bottom surface or pan  29  is made of a more durable material such as stainless steel or carbon fiber in order to resist puncture or damage from hazards on the road. It also is to be sealed and riveted or otherwise fastened to the spine  15  and perimeter channel ears  27   e  in order to create an oil and water tight seal. 
     Power source modules  31  are connected in a perpendicular fashion to the spine  15  and perimeter channel  27  and then concealed, bathed in coolant, and protected by the lid  28  and pan  29 . These modules  31  can be added to or subtracted from the spine  15 , and the spine  15 , perimeter channel  27 , lid  28  and pan  29  can be any length conceivable. Cooling cores  9   a  can be placed interchangeably with power modules  31  to alter the performance of the power source container  17 , or an empty space can be left for weight distribution purposes. These are the details of the first ALE battery bank container  17  and are not to be understood as a limitation to the scope of the invention protected herein. 
     Description of Two-Stage Power Container Manipulation 
     Now with reference to  FIG. 12  and its panels A-F, the panels are a step-by-step depiction to provide aid in the teaching of the two-stage container  17  manipulation sequence. 
     During early development it was noted that container  17  stabilization during the lowering and lifting process was a challenge. The container  17 , being a large flat and heavy object should never be able to swing, wobble, pitch, or twist while between a terminal  12   a ,  12   b ,  12   c  and a vehicle  30 . Many other designs where conceptualized in order to come up with a solution to this specific issue. The difficulty in each of those designs was that they required added complication which can also be understood as added cost, shorter life, and less durability (prohibitive of scalability). Since low cost and long life are key factors of high scalability, the following method was developed to preserve simplicity. 
     Panels A-F depict a two-stage lift lifting and lowering process to allow the implementation of an extremely simple lift mechanism to achieve reliable removal and replacement of the container  17 , out of and into a vehicle  30 , thus eliminating the need for expensive and unreliable complexities. Panels A-F are a series of step-by-step views along the process of power exchange of vehicle  30  which demonstrate the two-stage container manipulation process. The present method of lifting and lowering the container  17  only requires that the contact point  131  on the container  17  be slightly off-center of gravity in the direction opposite of the terminal base  124  and pivot point  121  of the boom  120 , as identified in location  33  along the longitudinal axis. The result is a two-stage lifting and lowering process where the container  17  is always in contact with the vehicle  30 &#39;s locks  134   a ,  134   b  or the terminal  12   a &#39; s boom  120  or both. This provides a minimum three points of contact at all times, two points being the left and right side of the lock  134   a ,  134   b  connected to the pins  19  ( FIG. 9 ) on the left and right side of the bite  18  at the end of the container  17 , and the third being the boom-tip  122  and container  17  contact point  131 . 
     Referring now to Panel A, at a first step, vehicle  30  has container  17  locked in the riding position over an empty power exchange terminal  12   a.    
     Referring now to Panel B, the terminal  12   a &#39;s lift mechanism is activated, and once contact is made between the boom-tip  122  of the lift mechanism and the contact point  131  of the container  17 , the vehicle&#39;s container locks  134   a ,  134   b  release. At this point, the boom-tip  122  will bear the container  17 &#39;s weight. 
     Referring now to Panel C, since the contact point  131  on the container  17  is off-center, in the direction opposite the boom pivot  121 , and the container  17  is also able to teeter at the contact point  131 , the container rotates off of the rear lock while remaining in contact with the front lock. 
     Referring now to Panel D, since stoppage of the teetering effect is achieved by the heavier end of the container  17  coming to contact with the container rest  32 , which is located on the boom  120  of the lift near its base  124 , the container  17  is now rigid with the boom  120 , having three points of contact at the left and right sides of the rest  32 , and once again, at the boom-tip  122 . 
     Referring now to Panel E, since the boom  120  and container  17  are now rigid with one another, as the boom  120  continues toward the ground, the container  17  drops away from the front lock  134   a , and the container  17  is now removed from the vehicle  30 . 
     Referring now to Panel F, once the container  17  is in the low resting position (with the boom  120  fully retracted), the heavier proximal end is supported by lying on the container rest  32 , and the distal end is either free floating, or a rest may be used to support it in the case of very heavy and large containers  17 . 
     The vehicle  30  then moves under auxiliary power in position over a charged or fueled container  17  per the provided instructions, and reverses the process described above to retrieve it, lock it in place, and then exit the power exchange strip  12 . 
     Description of Locks 
     Referring now to  FIGS. 13-16 , as mentioned above, locks  134  are necessary to secure the container  17  to the vehicle  30  and allow it to safely proceed from the power exchange strip  12 , without the fear of the container  17  becoming detached from the vehicle  30  while in use. The locks  134  are firmly mounted to the vehicle  30  preferably at the front ( 134   a ) and rear ( 134   b ) ends of a pre-designed container cavity  17   a , situated at the lowest point possible within the vehicle  30 , and accessible from the under-side of the vehicle  30  to allow container  17  removal and replacement. As previously mentioned, in the case that a vehicle  30  is not designed for ALE, an adaptive framework fitted with locks  134   a ,  134   b  may be mounted to the vehicle  30 &#39;s under-side, given adequate operational ground clearance can be achieved. 
     The two main locks  134   a ,  134   b  of the currently disclosed design are identical, and are positioned at the front and rear ends of the container cavity  17   a  within the ALE compatible vehicle  30 . They each contain two latches  34  opposite each other, which receive the two pins  19  opposite of each other within the bites  18  at the front and rear ends of the container  17 . The pins  19  within the bite  18  of the container  17  are round, and once latched in place, act as a pivot point for the container  17 . This allows the smooth and secure rotations and movements of the container  17  as outlined above, during the two-stage lifting and lowering process. 
     The body of each lock  134   a ,  134   b  is a rectangular box and is divided into three cavities. The left and right side cavities  11   d  contain pin guides and latches  34 , and the center cavity  11   c  contains the latch actuators  35 , a camera  36 , a small air pump (not shown), laser receiver  37 , and radio receivers (not shown) which gather positioning data and send it to the central processor in the vehicle  30  (this data allows the logic within the processor to react with signals sent to the control hardware installed in the vehicle  30 ). 
     The box-like shape of the lock  134  is tapered  38  toward the bottom to guide any slight misalignment of the container  17  to the correct position for receiving the pins  19  into the saddles  34   s  of the latches  34 . When the container  17  is pressed upward, against the vehicle  30 , by the terminal  12   a ,  12   b ,  12   c &#39;s boom  120 , the two front and rear locks  134   a ,  134   b  guide it in the final moments to the proper riding position within the vehicle  30 . As the lock  134  proceeds into the bite  18  of the container  17 , the pins  19  in the bite  18  compress the latches  34  against a spring, when the container  17  is firmly seated, the pins  19  pass over the end of the latches  34 , and the spring slaps them shut. At this point the container  17  is firmly secured to the vehicle  30 . To release the container  17 , the lift mechanism must press the container  17  against the vehicle  30 , and then the processor will activate the latch actuators  35  to open them against the spring, and allow the pins  19  within the bite  18  of the container  17  to freely pass out of the guides  39  and off of the lock  134 . 
     In addition to securing the container  17  to the vehicle  30 , and containing guidance feedback hardware ( 36 ,  37 ), the third key purpose of the locks  134  is to complete a reliable and safe electrical connection between the main power source within the container  17 , and the drive system of the vehicle  30 . This is achieved by a downward pointing plug  40  on the front face of each lock  134 , and matching upward pointing booted  42  receptacles  41  on the associated container  17  located on the front and rear facing surfaces of the bites  18 . Once the container  17  is pressed into the riding position of the vehicle  30 , the plug  40  and receptacle  41  are connected, and the air compressor within the lock  134  keeps the receptacle boot  42  pressurized slightly above external atmospheric pressure. This method allows the connection to be completely submerged without the danger of an electrical short caused by intrusive water. 
     The design of the presently disclosed locking system is intended to keep as much hardware necessary to complete a power exchange contained to the locks  134 , so that no other hardware such as cameras or other feedback mechanisms must also be located and mounted elsewhere on the vehicle  30  by the manufacturer. 
     Description of Charging or Refueling Plaza 
     Referring now to  FIG. 17 , in one advantageous form, a power exchange plaza  150  can be constructed of simplest form with a plurality of power exchange strips (e.g.  12   a - 12   e ) positioned in parallel (geometric) on a flat surface such as a concrete parking lot or a highway safety rest area. Autonomous routing can then be created to feed vehicles (e.g.,  30   a - 30   d ) with depleted power sources in one side of the plaza  152 , lead them to the appropriate strip (e.g.  12   b ) containing the appropriate container  17  with charged power source, and then lead them out the opposite side of the strip (e.g.  12   b ) once the exchange has been executed and finally out of the plaza exit  154 . This process is also compatible with manually operated vehicles  30 , in which case can be driven by the operator to the appropriate strip  12  containing the correct container  17  with charged power source for the vehicle  30 , and then engaged by the system at the engagement area  157 , where manual driving is suspended, and autonomous control is engaged. Finally, once the vehicle  30  has completed power exchange, autonomous control is suspended, and manual control is reinstated at the disengagement area  30   d.    
     The strips ( 12   a - 12   e ) can be organized to suit the area&#39;s vehicle power needs. Dramatically different sizes of containers  17  (e.g. containers  17   d  and  17   g ) with different types of power sources can be serviced by category-specific strips ( 12   a - 12   e ), but one strip  12  may service a variety of similar sizes and styles within preset parameters. The purpose for this flexibility is to allow a wide variety of sizes and styles of containers  17  and power sources to be ALE compatible. 
     Description of ALE Data Collection and Routing System 
     All ALE containers  17  will incorporate multiple sensing technologies to record and report temperature, output, charging indicators, and a host of other meta-data related inputs. The units will also all be equipped with a processing chip, locator, clock and memory card in order to store data from these sensors along a timeline. This will provide a detailed history on the use of the power container  17 , its current status and charge, as well as any problems it may have. This data is then pulsed from the vehicle  30  via the connected-car-network to a remote server if the vehicle is so equipped, or in the case of non-connected cars the data is uploaded to a remote server once the container  17  is connected to a terminal along any ALE strip. The data is then stored, analyzed and projected to the system interface or API. Internet access is then made available to approved users who can then pull real-time data from the network of containers  17  around the globe. This data can then be used by applications within a smart-phone, PC, or the vehicles  30  infotainment system to determine which container  17  should be engaged. Feedback to the systems remote server indicating the route selected by the vehicle occupants can also be used to reserve the power containers  17  necessary to complete the trip. Using such a network with real-time data provided by the ALE data collection system would also allow emergency services using ALE equipped vehicles  30  to gain priority access to charged power sources in the event of an emergency. 
     Description of Two-Way Charging and Power Storage 
     Advantageously a two-way charger, or charger/inverter can be used in concert with the presently disclosed power exchange system  10  to achieve decentralized grid storage. When the containers  17  having power sources, are connected to the charger via the terminal connection  133 , and the charger connected to the external power supply, they can be used as power storage devices for the surrounding grid. Such storage is useful in emergencies, to provide power in the case power cannot be provided by normal means. Additionally, renewable power sources such as wind and solar power, produce power on a naturally controlled schedule, while human power consumption is often on a very different schedule. Decentralized power storage as provided by the current invention, can buffer these inconsistencies, and allow the dream of wind and solar powered transportation to become a reality. 
     Although an electric vehicle  30  with requisite power source is described, other powered vehicles including ones using fuel cells can be adapted to use this technology. 
     Further, the present method and system have unique advantages over prior known technologies realized by using the vehicle  30  itself as the main mechanization of the process, which thereby lowers cost significantly. 
     The following description provides for a better understanding of the present method and system. The primary difference between the &#39;011 method and system and the present method and system is that the lift mechanism of the present invention is deployed at each power exchange terminal (e.g.  12   a ,  12   b ,  12   c ), rather than having the lift mechanism be on-board the vehicle (e.g.  30 ) requiring power exchange
