To prevent batteries from running out while suppressing a main battery of a vehicle from being exhausted by setting timing for performing supplementary charging from the main battery to a sub-battery based on a temperature forecast.SOLUTION: A management device manages the remaining power of a sub-battery of a vehicle that includes a main battery and the sub-battery. The management device acquires remaining power information of the sub-battery at the time when the vehicle starts parking. The management device predicts a remaining power drop timing at which the remaining power of the sub-battery falls below a threshold while the vehicle is parked, based on the acquired remaining power information. The management device obtains a temperature forecast for an area where the vehicle is parked after the vehicle starts parking. The management device sets supplementary charging timing for performing supplementary charging of the sub-battery using power of the main battery to a timing earlier than the predicted remaining power drop timing based on the temperature forecast.SELECTED DRAWING: Figure 3 【課題】気温予報に基づいてメインバッテリからのサブバッテリへの補充電を行うタイミングを設定することにより、車両のメインバッテリの消耗を抑えながらバッテリ上がりを抑制する。【解決手段】メインバッテリとサブバッテリとを有する車両のサブバッテリの残量を管理する。車両の駐車開始時のサブバッテリの残量情報を取得する。取得した残量情報に基づいて、車両の駐車中にサブバッテリの残量が閾値よりも低下する残量低下タイミングを予測する。車両の駐車開始後の車両の駐車地域の気温予報を取得する。メインバッテリの電力を用いてサブバッテリの補充電を行う補充電タイミングを、気温予報に基づいて、予測した残量低下タイミングよりも前のタイミングに設定する。【選択図】図３
