To improve the accuracy of estimating the degree of deterioration of a power supply or a component arranged around the power supply.SOLUTION: A life determination device according to an embodiment includes a temperature measurement device and a life determination unit. The temperature measurement device measures the temperature of a power supply. The life determination unit calculates a deterioration level of the power supply during a period when the power supply is operating based on an operating time of the power supply, the power supplied by the power supply, and the temperature of the power supply, calculates a deterioration level of the power supply during a period when the power supply is not operating based on a time when the power supply is not operating and the temperature of the power supply during the time when the power supply is not operating, and determines that the power supply has reached the end of its life when a value obtained by accumulating the calculated deterioration levels exceeds a predetermined threshold value.SELECTED DRAWING: Figure 5
【課題】電源もしくは電源の周囲に配置された部品の劣化度の推定精度を向上する。【解決手段】実施形態に係る寿命判定装置は、温度計測装置と寿命判定部とを具備する。温度計測装置は、電源の温度を計測する。寿命判定部は、電源の稼働時間と電源が供給する電力と電源の温度とに基づいて電源が稼働している期間における電源の劣化度を算出し、電源が稼働していない時間と電源が稼働していない時間における電源の温度とに基づいて電源が稼働していない期間における電源の劣化度を算出し、算出した劣化度を累積加算した値が所定の閾値を超えた場合、電源が寿命に達したと判定する。【選択図】図5
