차량 탑재 이차 전지의 충방전 제어 장치는, 엔진과 회전 전기와 이차 전지인 축전 장치를 탑재하는 차량에 있어서 엔진으로부터 축전 장치로의 전력 공급이 정지하고 있으며, 축전 장치가 방전에 의해 전해액 중의 이온 농도가 치우치는 정도를 나타내는 지표값을 취득하고, 차량의 시프트 레버 기구로부터 시프트 포지션을 취득하고, 취득된 시프트 포지션이 뉴트럴 포지션이며, 취득된 지표값이 전지 열화 발생 역치를 초과할 때에, 통지 수단에 대하여, 뉴트럴 포지션을 다른 시프트 포지션으로 변경하는 내용 경고 통지를 행하게 한다. In the present invention, in a vehicle equipped with an engine, a dynamo-electric machine, and a secondary cell as a power storage device, when supplying of electric power from the engine to the power storage device is stopped, an indicator value indicating the degree to which the ion concentration in an electrolytic solution is biased by discharging of the power storage device is acquired, a shift position is acquired from a shift lever mechanism of the vehicle, the acquired shift position is the neutral position, and the acquired indicator value exceeds a threshold value at which cell degradation occurs, the charging/discharging control device for an onboard secondary cell according to the present invention causes a notification means to issue a notification as a warning to change from the neutral position to another shift position.
