1. An electric power supply system that is supplied with electric power from an electric power supplier through a power line based on an electric power supply contract comprising:

  • a main breaker arranged in the power line to intercept an electrical link between the electric power supplier and the power line if a first predetermined value of current flows through the power line;

    a sub breaker arranged in a sub line that is electrically connected with the power line to intercept an electrical link between the main breaker and the sub line if a second predetermined value of current flows through the sub line;

    an energy storing portion that stores energy by being operated with the electric power supplied from the electric power supplier, the energy storing portion being electrically connected with the sub line;

    a current detector arranged in the sub line to detect a value of current supplied to the energy storing portion; and

    a controller controlling an energy storing operation of the energy storing portion and controlling an electricity storing operation of a battery of a vehicle when the battery is connected to the sub line, whereinthe controller causes the battery to store electricity with an electric current equal to or lower than a current value that is calculated by subtracting the value of current detected by the current detector from the second predetermined value of current.
