Charging power management device and charging power management method

In order to solve the problem that when the number of electric vehicles increases in the creation of a charging plan for electric vehicles, the calculation becomes large and the resource required for calculation increases, the present disclosure is provided with: a grouping unit (203) for grouping a plurality of electric vehicles into an electric vehicle group on the basis of a classification rule; a total charging power determination unit (204) that determines, for each group, the total charging power of the charging power of the electric vehicle group for each time on the basis of a constraint condition; and an individual charging power determination unit (205) that determines individual charging power for each electric vehicle for each time on the basis of the total charging power. 本公开为了解决在电动汽车的充电计划的制作中当电动汽车的数量增加时计算变得庞大、计算所需的资源增加这样的课题，特征在于，具备：分组部(203)，根据分类规则对多辆电动汽车进行分组而设为电动汽车群；总充电电力决定部(204)，根据约束条件，针对每个分组针对每个时间决定电动汽车群的充电电力的总充电电力；以及单独充电电力决定部(205)，根据总充电电力针对每个时间决定每个电动汽车的单独充电电力。
