发明名称 Battery swell triggered override system
摘要 A battery dimensional change detection system and associated methods provide battery “swell” detection capabilities for an electronic device. In this way, excessive dimensional changes that are detected lead to shutting off the power supplied by the battery. According to one aspect, a battery dimensional change detection system broadly includes a testing circuit, a voltage detection device, and a shut-off switch. The testing circuit is formed by one or more electrically conductive members and extends across an exposed portion of the battery, such that the circuit possesses first and second terminal ends. The voltage detection devices engages the first and second terminal ends to measure the voltage across the testing circuit. Selectively responsive to the particular voltage measurement value, the shut-off switch may prevent further battery discharge in the electronic device, thereby acting to inhibit further battery dimensional change.
