Abstract: A method and apparatus for short circuit detection for batteries. Some embodiments of a method include receiving a battery pack in a system, where the battery pack is rechargeable and includes multiple battery cell blocks, each cell block including one or more battery cells. The voltages of the plurality of cell blocks are monitored. Upon shutting down the system, the voltages of the plurality of cell blocks are logged to generate a set of logged voltage values. Upon restarting the system, the current voltage values of the cell blocks are measured. A determination whether any of the battery cells of the battery pack has developed a short circuit is made based at least in part on a comparison of the current voltage values with the set of the logged voltage values.

Abstract: A nonaqueous electrolyte secondary battery of the present invention includes a nonaqueous electrolyte and a positive electrode 13 that occludes lithium ions reversibly. The positive electrode 13 includes active material layers 13b and a sheet-like collector 13a that supports the active material layers 13b. The collector 13a contains aluminum and at least one element other than aluminum. The average composition that is obtained by averaging the ratio of the elements composing the collector 13a in the direction of the thickness of the collector 13a is equal to the composition of an alloy whose liquidus temperature is 630° C. or lower. The present invention makes it possible to prevent heat from being generated due to an internal short circuit in the nonaqueous electrolyte secondary battery.

Abstract: A method and system for intelligent battery charging rate management. Some embodiments of a method include determining a time period available for charging a rechargeable battery from an initial charge state to a final charge state. A second time period is determined, the second time period being an amount of time required to charge the battery from the initial charge state to the final charge state using a first charging process, with the first charging process including a first current value. If the first time period is greater than the second time period, then a reduced second current value is determined that is sufficient to charge the battery to the final charge state, and the battery is charged with a current of the second current value.
