To reduce a battery charging time of an electric vehicle for delivery, and optimize a battery loadage by suppressing deterioration of a battery.SOLUTION: A secondary battery management device 100A comprises: a power calculation unit 112 that calculates a predicted power W2 which is predicted to be required for a mobile vehicle to move along a designated planned moving route Rt, based on a power database 142 for recording a required power corresponding to a moving route of and a moving date and time or an ambient temperature when moving of the mobile vehicle driven by a secondary battery; and a travel-starting-state determination unit 114 that calculates a used SOC area of the secondary battery which can secure the predicted power W2 or a used voltage area according to a traveling condition, by referring to a battery deterioration database 144 which records a deterioration state of the secondary battery or records the past used state of the secondary battery along with data which shows a correlation between the used state and the deterioration state of the secondary battery, and determines conditions of SOCs and Vs at the start of traveling based on the calculated used SOC area or used voltage area.SELECTED DRAWING: Figure 2

    【課題】配達・配送用電気自動車の電池充電時間を短時間としてかつ電池劣化を抑制して電池搭載量を適正にする。【解決手段】二次電池管理装置100Aは、二次電池によって駆動される移動体の移動日時または移動時外気温と、移動経路と、に対応して所要電力量を記憶する電力量データベース142に基づいて、移動体が指定された移動予定経路Rtを移動するために要すると予測される予測電力量W2を算出する電力量算出部112と、二次電池の劣化状態を記録し、または、二次電池の使用状態と劣化状態との相関関係を示すデータとともに二次電池の過去の使用状態を記録した電池劣化データベース144を参照し、走行条件に応じて、予測電力量W2を確保できる二次電池の使用SOC領域または使用電圧領域を算出し、算出した使用SOC領域または使用電圧領域に基づいて、走行開始時条件SOCs,Vsを決定する走行開始状態決定部114と、を備える。【選択図】図2
