  • Publication number: 20220289056
    Abstract: A battery consumption amount from when an electric vehicle departs a base charging location to when the electric moving body has returned to the base charging location is set as a consumption amount of one day, and an estimated consumption amount of one day is calculated based on the consumption amounts of the past n days.
