电池充电保护电路
摘要：
本发明提供一种电池充电保护电路，用于在电池的温度超出可充电温度范围时停止对电池进行充电。该电池充电保护电路包括：一电阻模块，该电阻模块包括一热敏电阻；一电压比较模块，该电压比较模块与该电阻模块相连，该电压比较模块中设置有一电池最高充电温度对应的上限电压值和电池最低充电温度对应的下限电压值，该电压比较模块通过比较该热敏电阻上的电压值是否超出该上限电压值及下限电压值之间的范围而确定该电池的温度是否超出可充电温度范围，并在电池的温度超出可充电温度范围时，发出一控制信号；以及一电池充电控制模块，该电池充电控制模块接收到该控制信号后停止对电池充电。
摘要（英）：

The invention provides a battery charging protection circuit which is used for stopping battery charging when temperature of a battery exceeds a chargeable temperature range. The battery charging protection circuit comprises a resistance module, a voltage comparison module and a battery charging control module, wherein the resistant module comprises a thermistor; the voltage comparison module is connected with the resistance module, an upper-limit voltage value corresponding to maximum battery charging temperature and a lower-limit voltage value corresponding to minimum battery charging temperature are set in the voltage comparison module, and the voltage comparison module is used for determining whether the temperature of the battery exceeds the chargeable temperature range by comparing the voltage value of the thermistor with the upper-limit voltage value and the lower-limit voltage value and sending a control signal when the temperature of the battery exceeds the chargeable temperature range; the battery charging control module is used for stopping battery charging after the control signal is received.
