  • Publication number: 20160343091
    Abstract: A charging and billing system for an electric car systematically manages an electricity supplier who supplies electricity for charging and a consumer who uses electricity for charging and reasonably and accurately calculates a fee based on a criterion for calculating a fee for electricity used for charging. The charging and billing system for the electric car includes a billing system of an electric power company configured to supply electricity, a management operator configured to manage an electric supply unit installed by the electric power company for charging and to settle the fee for electricity used for charging with the electric power company, a mobile communication network configured to provide a communication service in connection with the management operator, and a settlement company configured to settle the fee for electricity used for charging. When the electric car is charged, the fee for electricity used for charging is offset between the management operator and the electric power company.
