摘要

一种充电电池温度侦测方法，用于一电子系统，包含有当一外部电源输入该电子系统之一电源转换模组时，侦测该电子系统之一处理器之状态；以及根据该处理器之状态，决定将该电子系统中一热敏电阻导通至一电量计或一充电控制电路，以由该电量计或该充电控制电路透过该热敏电阻判断一温度感测结果；其中，该热敏电阻相邻于一充电电池，并具有可根据该充电电池之温度变化之一电阻值，该温度感测结果相关于该电阻值。; determining whether a thermistor of the electronic system is conducted to a fuel gauge or a charge control circuit according to the state of the processor such that the fuel gauge or the charge control circuit determine a temperature sensing result with the thermistor. The thermistor is disposed adjacent to a rechargeable battery and has a resistance varying with a temperature of the rechargeable battery. The temperature sensing result relates to the resistance.
