Abstract
A charge controller for controlling the charging of a battery provided inside a vehicle using a control signal supplied from an external power source apparatus via a power cable includes a control section for controlling the charging of the battery and an activating section for activating the control section inside the vehicle. The external power source apparatus switches the control signal from a non-oscillation state to an oscillation state when the preparation for power supply is completed. The activating section has an oscillation state judgment section for judging whether the input control signal is in the oscillation state or the non-oscillation state and for outputting an oscillation state judgment signal and an activating signal generation section for generating an activating signal for activating the control section when the oscillation state judgment signal is switched from a state indicating non-oscillation to a state indicating oscillation.
