To enable notification to a user, if a vehicle battery has a symptom of abnormality.SOLUTION: On determination that there is an abnormal symptom in a battery 7 based on the terminal voltage of the battery 7, a control unit 15 supplies a voltage to at least a specific functional circuit 2a of an SoC 1 to notify that there is a symptom of abnormality in the battery 7 using an LED 9. This enables notifying a user of that event if there is a symptom of abnormality in the vehicle battery 7.SELECTED DRAWING: Figure 1

    【課題】車両のバッテリに異常な兆候がある場合であってもそのことをユーザに通知することが可能とする。【解決手段】制御部15は、バッテリ7の端子電圧に基づいてバッテリ7に異常な兆候があると判断した場合は、少なくともSoC1の特定の機能回路2aに電圧を供給してLED9によりバッテリ7に異常に兆候があることを通知する。これにより、車両のバッテリ7に異常な兆候がある場合であってもそのことをユーザに通知することが可能となる。【選択図】図1
