    • A protection circuit for a battery pack, comprising: a thermistor for indicating a temperature of a cell in the battery pack; a first comparator coupled to the thermistor for determining whether the temperature has exceeded a charge cut-off temperature threshold for the cell, and if so, for turning off a first switch in series with the cell to prevent: charging of the cell; and, a second comparator coupled to the thermistor for determining whether the temperature has exceeded a discharge cut-off temperature threshold for the cell, and if so, for turning off a second switch in series with the cell to prevent discharging of the cell.
    • 一种用于电池组的保护电路,包括:用于指示电池组中的电池的温度的热敏电阻; 耦合到所述热敏电阻的第一比较器,用于确定所述温度是否超过所述电池的充电截止温度阈值,如果是,则关闭与所述电池串联的第一开关,以防止所述电池充电; 以及耦合到所述热敏电阻的第二比较器,用于确定所述温度是否已经超过所述电池的放电截止温度阈值,如果是,则关闭与所述电池串联的第二开关以防止所述电池放电。
