The electric power supply system includes a stationary device and a mobile device. The mobile device includes a rotary electric machine driven by an engine, a vehicular battery which is used to move the vehicle, and an emergency battery. The stationary battery in the stationary device may be charged by either one of the rotary electric machine, the stationary battery or the emergency battery via an inter-battery power line. The amount of charge to the stationary battery is set based on an amount of necessary power WRQ which the stationary device needs, and an amount of available power WVH which the mobile device can supply. The stationary battery can be charged in an efficient manner and with a sufficient amount of electric power.
