摘要： 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.

摘要： A system and method for automatically adjusting microprocessor activity following thermal stress of a voltage regulator is disclosed. A thermal monitoring circuit determines whether the voltage regulator has exceeded a predetermined temperature. The thermal monitoring circuit may employ a temperature-sensing component such as a thermistor to determine the temperature or may derive the temperature indirectly, based on the average input (or output) current. When the over-temperature condition occurs, a signal activates the PROCHOT#, or similar, pin on a microprocessor, throttling the microprocessor clock. Where the microprocessor includes no internal power-reducing feature, the signal throttles an external clock coupled to the microprocessor. In either case, execution of the microprocessor is slowed down. At all times, the voltage regulator maintains the ability to supply continuous current to the microprocessor.
