|20130288083||FIRE SUPPRESSENT BATTERY PACK - A fire suppressant battery system has a battery pack, a non-conductive fire suppressant liquid in a fire suppressant bladder, and a fire suppressant protective layer. The bladder melts at a temperature above the battery pack's desired operating condition, has a cavity for receiving the liquid and contacts at least a section of the battery pack. The protective layer is positioned onto a portion of the fire suppression bladder's exterior surface that is on the opposite side to that which contacts the battery pack.||10-31-2013|
|20130154567||Balancing Discharge in Parallel Battery Configurations - An apparatus balances a discharge in parallel battery configuration by having a battery pack (a) with a first battery system and a second battery system in parallel configuration, and a pulse width modulation device and (b) being interconnectable to a load. Each of the first and second battery systems has, in series and in order, a first voltage sensor, a resistor, a second voltage sensor, a string of battery cells, and a switching device. The first and second voltage sensor, in each battery system, measures an electrical current, used to calculate the voltage drop across each resistor. The voltage drop values for each battery system determine whether the pulse width modulation device alters or maintains the pulse width modulation applied to each battery system's switching device. By maintaining or altering the pulse width modulation applied to each switching device, the apparatus effectively balances the electrical current discharge from each battery system.||06-20-2013|

|20100178547||MODULAR BATTERY PACK - A modular battery pack comprised of multiple modular batteries arranged in series, in parallel, or in series-parallel combinations is described. Each of the modular batteries is comprised of a first pair of opposed keyed side walls for series connection between adjacent modular batteries, and a second pair of opposed keyed side walls for parallel connection between adjacent modular batteries. The modular batteries are only able to connect to each other when the keys are matched and aligned. Additionally, the opposed end walls of the modular batteries have specifically configured terminals that prevent the possibility of making undesired connections between adjacent modular batteries.||07-15-2010|
