       FIELD 
       [0002]    The present invention relates generally to a portable automotive battery jumper pack with detachable backup battery. Specifically, the invention comprises of a detachable backup battery within the main body of the battery jumper pack directed to the automotive and rechargeable consumer electronic arena. 
       BACKGROUND 
       [0003]    This invention is distinctly different from a conventional automotive battery jump start system. Traditionally, a conventional battery jump start system&#39;s main purpose is to provide energy to depleted or weak automotive batteries, whenever the automotive battery cannot start the engine&#39;s electrical system due to lack of energy. In essence, a battery jump start system complements and aids in starting a failed system. Conventional battery jump starter systems may include features such as an area light, universal serial ports, power supply output receptacle. These features are integrated in a single embodiment making it cumbersome due to its heavy weight and lack of flexibility in design. These jump starter systems tend to be heavy and contain sealed lead acid batteries. Another downside is the conventional battery jump starter system must be recharged every few months in order to maintain a useful level of power. Continued charging is required because of the inherent self-discharge characteristic of internal batteries. If the unit is not properly charged, it will be of no use to the consumer when they find themselves with a dead or depleted automotive battery. 
       SUMMARY 
       [0004]    The objective of the present invention is to provide a newer, efficient and easy to use jumpstarter with a method of combining two electrical systems to supplement overall performance and usefulness to the end user. First, the present invention achieves its objective by integrating a self-power management system that monitors the energy level of the main system battery and by the same system, replenishes the lost energy by drawing from the detachable backup battery pack. The system utilizes two different battery compositions. The main system will be comprised of a deep cycle sealed lead acid battery used for providing energy to a depleted or weak automotive battery requiring a quick boost in order to turn over (start) the engine&#39;s electrical system. The secondary system consists of a detachable back up battery pack made up a lightweight but high energy density cell similar to that of a lithium ion design. 
         [0005]    This particular invention, will surpass conventional systems functional capabilities in several ways. First, this invention will compensate for the self-discharge characteristic of batteries by automatically trickle charging the main system battery for relatively long periods of time using the battery energy inside the detachable backup battery pack. Significantly, users will no longer have to monitor the level every few months, because the invention provides a high density energy battery inside the detachable backup battery pack with low self-discharge that can maintain the main system battery fully charged for up to a year or longer. In addition, the detachable pack can be detached and carried away from the main system jumper and used to recharge or power personal electronic devices. The user no longer is bound by the limitation of conventional system of having these features integrated in a bulky and singular heavy pack. it&#39;s to be noted that there is no direct connection between battery cells as in other system where two battery cells are directly coupled in a parallel configuration in order to increase their capacity and or transfer the energy between cells. The invention houses a first main system described as an automotive battery jumper pack to be used to jump start automotive batteries when they are weak or depleted. The invention also houses secondary system described as a detachable backup battery to be used as a trickle charger for the main system as well as to recharge and power personal electronic devices. The described systems coexist electrically and also independently from each other, as each of them contain their own integral battery as a source of energy.

     DETAILED DESCRIPTION 
       [0010]    A description of the invention is discussed in detail below. In describing the invention, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology referenced herein. For clarity, the main system will also be describe as a complete portable automotive battery jumper (battery jumper). 
         [0011]    Referring now to the images of the invention. The present invention includes two different types of system coupled together to perform different functions when working together or separately from each other.  FIG. 1 , is a complete portable automotive battery jumper with detachable backup battery pack. The apparatus is a self-contained structure as shown by the main system enclosure  1 . The main system is contained within a series of deep cycle battery cells to be used as a supplement to automotive batteries. The main purpose of these cells is to provide energy to a vehicle whenever the vehicle battery is depleted and in need for a jump start to the electrical system of the vehicle. The main system enclosure  1 , delivers the power to the electrical system via conductors of different voltage potential  5  in conjunction with its battery clamps  4 . The system is safely activated to its jump start mode by using a manual power switch  6 . The size of the battery jumper conductors  5  are typically #4AWG, and at least four feet of length. The size of the battery jumper may vary in thickness and in length depending on the application. The described battery jumper conductors  5  contained color-coded battery clamps  4  red (+) and black (−) and they are to be directly connected to depleted battery of the electrical system according to proper polarity. The battery clamps  4  can accommodate in vehicle batteries with top or side terminal posts. The color-coded battery clamps  4  are made of copper material for maximum energy transfer. The main systems  1  internal battery cells can be recharged via two methods First, the main system  1  is recharged by plugging in an external AC power supply through port  6 . This will be the most efficient way to recharge the battery jumper&#39;s internal battery cells. The second method for charging the main system  1  internal battery cells is accomplished by using the detachable backup battery pack  2 . The detachable backup battery pack  2  contains a high energy density cell that transfer the necessary charge to the main systems  1  internal battery cells using an integrated male barrel connector  10  which provides a mechanical connection as well as an electrical connection between both systems. The rate of charge between the detachable backup battery  2  and the main system  1  is managed internally by the boost circuit trickle charger shown on  FIG. 4 . 
         [0012]    On  FIG. 2  as supporting document to  FIG. 1 , the image illustrates the two systems.  FIG. 2  shows how the portable automotive battery jumper pack and detachable backup battery are coupled. The main system  1  contains a cradle  8  that will house the detachable backup battery. The charging cradle  8  contains within a charging receptacle  9  that transfers energy from the detachable backup battery pack  2  to the main system  1  internal battery during trickle charging mode as in claim  6 . The detachable backup battery pack  2  also contains a power switch  7  that activates the dual universal serial bus when user needs to power or recharge personal electronic devices. The detachable backup battery pack  2  is fully operational when is docked to the charging cradle  8  or when is outside the cradle  8 . This grants access to the user to the dual USB ports  12  &amp;  11  on  FIG. 3  built into the detachable backup battery pack  2 . 
         [0013]    Having a detachable backup battery pack provides users with an advantage over conventional systems. The user is not bound by a single integrated system. This particular component is referred on  FIG. 1  as item  2 . The detachable backup battery is also described on  FIG. 3  where the bottom view can be appreciated.  FIG. 3  shows the barrel pin connector  10 . It&#39;s sole purpose is to trickle charge the main battery system as in claim  10 . The barrel pin when not in use, is housed into the body of the detachable backup battery  13 . This retractable barrel pin connector  13  will carry small amount of current whenever it is coupled to the main system charging receptacle as previously shown on  FIG. 2   
         [0014]      FIG. 4  shows a diagram of the invention&#39;s electrical system operations. The invention is powered from a series of independent battery cells. The battery cells could be of same or different chemistry but not the same voltage potential. The reason for the difference in voltage potential is because the detachable backup battery  13  is intended for small electronic applications and the jump pack battery is intended for automotive applications. The output of the detachable backup  7  battery is nominal five volt whereas the output of the jumper pack  1  is twelve volt. Therefore a boost converter circuit is built in the jumper pack  1  which increases the voltage from the detachable backup battery  13  without the need for increasing the number of cells. Simultaneously, the boost converter circuit provides a low charging current to the battery cells of the jumper pack  1 . As initially described, this invention integrates a self-power management system that monitors the energy level of the main system battery and at the same time, replenishes the lost energy by drawing from the detachable backup battery pack  1  when this is connected to the dock station cradle  8 .
