Charging device for eco-friendly vehicle

The present invention (Control Pilot) CP to be applied during that, more specifically, connected to the power supply (EVSE) of the vehicle outside of the vehicle charge device to charge the battery in the vehicle by the power supplied from the power source of the vehicle outside implementing the first controller (OBC CPU) reserved charging ability to a built-in circuit for on / off control the power supply to reduce the constant supply current of the charger (OBC) for controlling the operation of the charger (OBC) in accordance with the properties of the signal to provide a vehicle charging apparatus having a built-in circuit for it is an object. In other words, by the present invention, a circuit capable of performing (Control Pilot) signal detection and reservation charge CP function in the charger (OBC), charger (OBC) alone charger controller in accordance with the properties of the CP (Control Pilot) signal (OBC CPU) turned on (on) / off (off) controls the power and to reduce the current consumption at all times to perform a scheduled charging.
