The battery ECU updates the frequency data of the area using the temperature TB and SOC of the battery as parameters, and estimates the degradation degree (degradation amount) from the frequency data and the degradation coefficient that increases as the temperature TB increases. The degradation degree is stored in the control ECU. When the battery ECU is replaced, the battery ECU acquires the degradation level from the control ECU and creates a new frequency based on the degradation level. The new frequency data is created as frequency data F of an area having a high temperature TB and a large SOC, and the other area is set to a NULL.
