Patent ID: 7688024

Claim:
A charge control device for a vehicle mounted with a power storage device for driving the vehicle, the charge control device being capable of charging the power storage device with a supply electric power from a power supply outside the vehicle in a case where the vehicle and the power supply are connected by a coupler, the coupler outputting a supply electric power signal indicating information about the supply electric power in a case where the coupler is connected to the vehicle and the power supply, the charge control device comprising: a control line for transmitting the supply electric power signal; a resistor having one end connected to the control line; a potential setting circuit setting a potential of the other end of the resistor to a first potential in a case where the vehicle is connected to the coupler and setting the potential of the other end of the resistor to a second potential higher than the first potential in a case where the vehicle is not connected to the coupler; and an abnormality detection unit performing a detection of a break of the control line based on a potential of the control line in a case where the vehicle is not connected to the coupler.
