Optimizing battery usage

## Abstract

## Background
FIELD OF THE INVENTION
Embodiments of the invention generally relate to information technology, and, more particularly, to battery usage.
BACKGROUND OF THE INVENTION
The environmental damage associated with inappropriate discard practices with respect to batteries is well documented, and yet large volumes of batteries continue to be disposed of inappropriately. Proper disposal prevents dangerous elements (such as, for example, lead, mercury, and cadmium) found in some types of batteries from entering the environment.
Rechargeable batteries have the potential to reduce the frequency of inappropriate battery disposal, because they will be discarded less frequently. However, the prevalence of non-rechargeable batteries remains.
Additionally, disposable batteries wane and lose charge with increased usage. Therefore, battery users may often discard such batteries before they have fully discharged, in order to avoid the risk of batteries dying suddenly in the midst of usage. Consequently, batteries may frequently have power remaining at the time that they are discarded, and such power is thereby potentially wasted upon disposal.

DETAILED DESCRIPTION OF EMBODIMENTS
Principles of the invention include greener battery usage. One or more embodiments of the invention include recovering remaining or residual energy stored in the battery, or draining the remaining or residual energy for reuse. Additionally, one or more embodiments of the invention include determining if a rechargeable battery can be recharged or if the remaining energy can be recovered for reuse, as well as dynamically adjusting battery recharge energy flow to optimize battery life.
As detailed herein, a battery can be inserted into a charge-optimizing device. In one or more embodiments of the invention, the charge-optimizing device can be dedicated, for example, “battery handler” or it can be software/hardware embedded in other multi-function units (for example, in the device (for example, a camera) itself).
One or more embodiments of the invention can additionally include assembling multiple batteries together in a compartment to reuse remaining energy from all or the batteries (scalability), which can allow for assembly of different types and configurations of batteries. A battery can be manually or automatically set to charge optimization. Manual setting can indicate that a user specifies that the function (for example, charge to be depleted or charge to be optimized) be accomplished. Automatically setting to charge optimization can indicate, for example, that the function is accomplished upon detection of certain conditions, such as current battery voltage level.
Also, battery type can be manually or automatically determined. A manual setting can indicate, for example, that a user selects non-renewable or renewable. An automatic setting can indicate that, for example, battery type can be detected by embedded query logic (the battery identifies itself), through, for instance, visual recognition (pattern matching for the battery casing), or through other means.
One or more embodiments of the invention can additionally include a personal history database of batteries, which can be used to learn lifetimes of batteries as well as charging/discharging history to learn about battery life over time. Sharing a database, for example, on the internet, can allow different users to share their databases with others. As such, one or more embodiments of the invention include storing information from a personal history database directly onto a shared website database. Further, a user monitor allows a user to have a visual representation of what is happening in a box (that is, a visual representation of a system where batteries are held) showing the energy status of each battery in a given compartment.
Accordingly, as described herein, one or more embodiments of the invention include techniques for charging and discharging batteries, designed to optimize battery life while recapturing otherwise-wasted power. One or more embodiments of the invention can include performing two related functions. Firstly, for single use devices, the techniques detailed herein include draining any remaining charge from a battery and storing that remaining charge in a separate device for later reuse. Secondly, the techniques described herein include, for rechargeable devices, detecting the nature of a battery, and draining it to an optimal level before recharging, so as to better condition the battery for longer life.
As noted herein, one or more embodiments of the invention can be performed manually or automatically. Automatic performance encompasses the detection of battery type (via, for example, visual, size, weight, current and voltage (I/V) diagram) and charging state before the function is accomplished.
If a battery is renewable, one or ore embodiments of the invention can include using a look-up table to determine an optimal charge/discharge pattern for maximal battery life, and further proceeding to appropriate recharge patterns. For example, for lithium-ion, battery life can be optimized by discharging to some optimal level (for example, discharge to 30%) for storage in a collection device for later use. The renewable battery is then recharged according to patterns designed to maximize battery life.
As further described herein, one or more embodiments of the invention includes a device that includes a module for inserting batteries for energy distribution, sensors for reading batteries' energy levels, a detachable energy box, and a battery manager to control energy flow between batteries and detachable box. Additionally, one or more embodiments of the invention can also include a temperature control module.
FIG. 1 is a diagram illustrating architecture for greener battery usage, according to an embodiment of the present invention. By way of illustration, FIG. 1 depicts a component 102 containing batteries with different compartments, including a compartment 106 having batteries of a specific type and known size, and a compartment 108 for unknown battery size. Component 102 also includes a liquid crystal display (LCD) 104 that contains information about the batteries.
FIG. 1 also depicts a component 110 with energy collected from the batteries in component 102 that can be detached from component 102 and connected to other energy sources. Additionally, a battery manager module 112 reads information about energy levels of the batteries in component 102 and controls a time of when and how long energy is taken from batteries in component 102. The battery manager module includes sensors that provide information as to how much energy is left in each battery in component 102. The battery manager module also includes a table or set of rules that facilitate prediction of how long the combination of remaining amounts of energy in all batteries (in component 102) is sufficient to provide required support (that is, is above some threshold).
Further, as depicted in FIG. 1, a personal history database 114 of batteries can be used to determine (and store) information pertaining to the lifetimes of batteries, as well as batteries' charging/discharging history to learn about battery life over time.
Also, FIG. 1 depicts a sharing database 116, which can be shared, for example, on the internet, which allows different users to share their “personal history database” with others. This can facilitate many users to learn better strategies to optimize battery life, and can be carried out automatically by storing information from a personal history database directly onto a shared website database. Further, FIG. 1 depicts a user monitor 118, which allows user to have a visual representation of what is happening in component 102, showing, for example, the energy status of each battery in compartment.
FIG. 2A and FIG. 2B are flow diagrams illustrating techniques for greener battery usage, according to an embodiment of the present invention. By way of illustration, in FIG. 2A, the techniques begin in step 202. Step 204 includes inserting battery into a component (such as component 102 in FIG. 1). Step 206 includes determining if there is a compartment (within the component) that fits the battery size in question. If there is a fit, the techniques can proceed to step 208, which includes putting the battery into an appropriate compartment. If the battery size will not fit into any compartment, the techniques proceed to step 210, which includes putting the battery into a dynamic compartment of the component and making any necessary adjustments.
Step 212 includes reading an energy level of the inserted batteries (within the component). Additionally, step 214 includes determining if a battery is re-chargeable. If a battery is not re-chargeable, the techniques (with respect to that battery) proceed to step 216. If a battery is re-chargeable, the techniques (with respect to that battery) proceed to step 218. As such, step 216 includes determining if the battery has residues of energy. If the battery does not have residues of energy, the techniques proceed to step 222, which includes ejecting the battery from the component (such as, for example, component 102 in FIG. 1). If yes, the techniques proceed to step 220, which includes marking that item as “allow to extract energy.”
Further, step 218 includes determining if the energy level in the battery is sufficient to recharge the battery. If the energy level in the battery is sufficient, the techniques proceed to step 224, which includes labeling the item as “recharge,” and allowing it to recharge. If the energy level in the battery is not sufficient, the techniques proceed to step 222.
Additionally, in FIG. 2B, step 226 includes determining if the label process has finished. If yes, the techniques proceed to step 228, which includes starting to recharge or extract energy. If the label process has not finished, the techniques proceed to step 230, which includes continuing to insert new batteries into the battery component.
Step 232 includes indicating priorities of energy flow for rechargeable batteries as well as detachable energy blocks. By way of example, priorities can be defined by various criteria such as, for instance, what batteries can be damaged if they do not enough have energy left, or which batteries have enough energy above a certain threshold after which they can be damaged. The priorities are defined by the battery manager module. Also, step 234 includes printing or displaying information about a battery process into a personal history database (for example, to be shared with other users). Step 236 includes finishing the techniques.
FIG. 3 is a flow diagram illustrating techniques for optimizing battery usage, according to an embodiment of the present invention. Step 302 includes sensing energy level of a battery. This step can be carried out, for example, using a sensor module. Step 304 includes comparing the sensed energy level of the battery to a predetermined energy threshold for the battery. This step can be carried out, for example, using a battery manager module.
Step 306 includes controlling energy flow to and from the battery based on the comparison of the sensed energy level and the energy threshold. This step can be carried out, for example, using a battery manager module and/or a detachable energy redistribution module. Controlling energy flow to and from the battery can include, for example, sending additional energy to the battery when the sensed energy level has a predetermined relationship to the energy threshold calling for additional energy to be sent to the battery. Additionally, controlling energy flow to and from the battery can include draining energy from the battery when the sensed energy level has a predetermined relationship to the energy threshold calling for energy to be extracted from the battery.
Also, controlling energy flow to and from the battery can be performed manually or automatically. A manual setting facilitates user specification that a particular function (for example, charge to be depleted or charge to be re-charged) be accomplished. An automatic setting facilitates that a particular function is accomplished upon detection of one or more conditions (such as, for example, current battery voltage level).
The techniques depicted in FIG. 3 can also include determining a battery type for the battery, wherein battery type includes one of re-chargeable and not re-chargeable. Determining a battery type for the battery can include manually determining a battery type for the battery and/or automatically determining a battery type for the battery. An automatic setting for determining a battery type for the battery can include using embedded query logic (the battery identifies itself), visual recognition (pattern matching for the battery casing), etc.
As described herein, one or more embodiments of the invention also include determining if a battery has residues of energy if the battery is not re-chargeable, and ejecting the battery for resumption of use or marking the battery for energy extraction if the battery has residues of energy. Such actions can depend, for example, on the amount of energy residues remaining in a non re-chargeable battery. For example, if the battery has a significant amount of energy left, the system may simply eject the battery for resumption of use (of that significant amount of remaining energy). The techniques depicted in FIG. 3 also include determining if the energy level of the battery is sufficient to recharge the battery if the battery is re-chargeable (for example, via using a look-up table to determine an optimal charge/discharge pattern for maximal battery life, and further proceeding to appropriate recharge patterns), and marking the battery for a recharge if the energy level in the battery is sufficient to recharge the battery.
Further, the techniques depicted in FIG. 3 can also include inputting information pertaining to a battery charge process into a personal history database.
The techniques depicted in FIG. 3 can also, as described herein, include providing a system, wherein the system includes distinct software modules, each of the distinct software modules being embodied on a tangible computer-readable recordable storage medium. All the modules (or any subset thereof) can be on the same medium, or each can be on a different medium, for example. The modules can include any or all of the components shown in the figures. In one or more embodiments, the modules include a sensor module, a detachable energy redistribution module, a battery manager module, a temperature control module, a personal history database, a sharing database and a display component that can run, for example on one or more hardware processors. The method steps can then be carried out using the distinct software modules of the system, as described above, executing on the one or more hardware processors. Further, a computer program product can include a tangible computer-readable recordable storage medium with code adapted to be executed to carry out one or more method steps described herein, including the provision of the system with the distinct software modules.
One or more embodiments of the invention also include an apparatus for battery usage optimization, wherein the apparatus includes a compartment to house one or more batteries (for example, component 102 in FIG. 1), a detachable energy redistribution module (for example, component 110 in FIG. 1), and a battery manager module (for example, component 112 in FIG. 1) to control energy flow between a battery in the compartment and the detachable energy module, wherein the battery manager module comprises one or more sensors for reading one or more battery energy levels, and wherein the battery manager module further includes a component for comparing the one or more battery energy levels to a predetermined energy threshold for each battery and controlling energy flow to and from each battery based on the comparison of the read energy level and the energy threshold. Such an apparatus, in one or more embodiments of the invention, can additionally include a personal history database (for example, component 114 in FIG. 1), a sharing database (for example, component 116 in FIG. 1), as well as a display component (for example, component 104 in FIG. 1). Additionally, in one or more embodiments of the invention, the battery manager module can include one or more temperature sensors. Temperature sensors facilitate the removal of batteries and control energy flow depending on the temperature of the batteries. For example, some batteries, especially ones that are damaged, become overheated during energy flow and should be ejected).
In one or more embodiments of the invention, in such an apparatus, the compartment to house one or more batteries can be dynamically adjusted to one or more battery sizes. Further, the detachable energy redistribution module can be connected to one or more additional energy sources. Additionally, the battery manager module, in controlling energy flow between a battery in the compartment and the detachable energy module, is operative to send additional energy to the battery from the energy redistribution module when a sensed energy level of the battery has a predetermined relationship to an energy threshold calling for additional energy to be sent to the battery, and also operative to extract energy from the battery when a sensed energy level of the battery has a predetermined relationship to an energy threshold calling for energy to be extracted from the battery.
Additionally, the techniques depicted in FIG. 3 (and described elsewhere herein) can be implemented via a computer program product that can include computer useable program code that is stored in a computer readable storage medium in a data processing system, and wherein the computer useable program code was downloaded over a network from a remote data processing system. Also, in one or more embodiments of the invention, the computer program product can include computer useable program code that is stored in a computer readable storage medium in a server data processing system, and wherein the computer useable program code are downloaded over a network to a remote data processing system for use in a computer readable storage medium with the remote system.
