Patent ID: 8368350

Claim:
A control system for supplying power from a power source outside a vehicle to a power storage device located in the vehicle, the control system comprising: a cable through which the power source outside the vehicle feeds the power storage device, the cable including at both ends a power source-side connector for connecting with the power source outside the vehicle and a vehicle-side connector for connecting with the vehicle, the vehicle-side connector including a signal pin, a series resistive element connected to the signal pin at one end, a switch connected in series to the series resistive element at one end and grounded at the other end, and a parallel resistive element connected in parallel to the switch and connected in series to the series resistive element, the switch changing from an ON state to an OFF state upon depression of a depression portion located on the vehicle-side connector by a user, at a time when the vehicle-side connector is connected to the vehicle, or at a time when the vehicle-side connector is disconnected off the vehicle; a resistive element located in the vehicle, the resistive element being electrically connectable to the signal pin at one end and grounded at the other end; and a control device located in the vehicle, the control device determining a state of the control system on the basis of a signal voltage value input from a signal line electrically connectable to the signal pin.
