| description | To provide a method for accurately measuring a battery temperature using a temperature sensor embodied in a battery monitoring integrated circuit.SOLUTION: The method includes performing calibration to estimate a thermal resistance between a battery monitoring integrated circuit 100 and a terminal 108 of a battery, measuring a temperature using a temperature sensor 104, measuring a voltage using a voltage sensor 102 at the terminal or at a supply pin of the battery monitoring integrated circuit while a current is being used to charge or discharge the battery, calculating a power by multiplying the voltage and the current together, and calculating a self-heating temperature adjustment to the temperature by multiplying the power and the thermal resistance.SELECTED DRAWING: Figure 1
【課題】バッテリ監視集積回路に施される温度センサを用いてバッテリ温度を正確に測定する方法を提供する。【解決手段】較正を行うことでバッテリ監視集積回路１００とバッテリの端子１０８との間の熱抵抗を推計することと、温度センサ１０４を用いて温度を測定することと、電流を用いてバッテリを充電するか又はバッテリを放電させる際に端子又はバッテリ監視集積回路の電源ピン上の電圧を電圧センサ１０２で測定することと、電圧と電流を乗算することによって電力を計算することと、電力と熱抵抗を乗算することによって温度に対する自己発熱温度調節を計算することと、を含む。【選択図】図１ |
