CHARGING POWER MANAGEMENT DEVICE AND CHARGING POWER MANAGEMENT METHOD

In creating a charging plan for an electric vehicle, calculation amount becomes enormous as the number of electric vehicles increases, leading to a problem of increasing the resources required for calculation. To solve this problem, the present disclosure includes a grouping unit configured to group a plurality of electric vehicles into an electric vehicle cluster based on a classification rule, a total charging power determination unit configured to determine total charging power of the electric vehicle cluster for each group for each time based on the restriction condition, and an individual charging power determination unit configured to determine individual charging power for each of the electric vehicles for each time based on the total charging power.
