1. A method of charging a battery, comprising:
releasably connecting a first connector of a charging device to a connector of the battery, the charging device allowing a user to electrically connect the battery with a charging station to recharge the battery;
releasably connecting a second connector of the charging device to a connector of a charging station, the charging station being connected to a power grid through a power line and receives power from the power grid, being connected to a server that generates billing information according to use of electric power, and including an electricity meter that measures electric power consumed by facilities of the charging station and communicates with the server;
performing, by the charging device, authentication for identifying the user of the battery;
transmitting, by the charging device, a charging initiation request to the electricity meter of the charging station for charging the battery upon completion of the authentication for identifying the user, the charging initiation request including a charging identifier for identifying the user;
receiving, by the charging device, a charging initiation response in response to the charging initiation request from the electricity meter, the charging initiation response including a meter identifier for identifying which electricity meter performs charging and the charging identifier;
performing, by the charging device corresponding to the charging identifier, charging by connecting the charging station with the battery and initiating charging after receiving the charging initiation response in response to the charging initiation request;
measuring, by the electricity meter, electric power provided to the charging station by the power grid;
transmitting, by the charging device, a charging completion message indicating electric power provided for charging to the electricity meter upon completion of the charging, the charging completion message including the charging identifier and the meter identifier; and
receiving, by the charging device, charging information indicating billing information according to the charging of the battery from the electricity meter based on an amount of electric power consumed by the charging station and the amount of electric power consumed by the charging device,
wherein the charging information includes the charging identifier and the meter identifier.
