Problems solved by technology
[0005] Conventionally, when power is supplied to the outside of the vehicle, since the button for power supply is installed in the vehicle-mounted device, power can be supplied to the outside of the vehicle only while sitting in the vehicle, which is inconvenient
[0006] In addition, conventionally, when connecting a connector for supplying power to the outside of the vehicle to the insertion port, there has been a problem that it is difficult to recognize the closed state of the discharge start button for supplying power.

The present invention relates to a vehicle charge / discharge control device, a vehicle charge / discharge system including the same, and a vehicle charge / discharge control method, the vehicle charge / discharge control device according to one embodiment of the present invention comprises: a processor that controls charging and discharging of electric energy of a vehicle; and a storage unit storing data and an algorithm executed by the processor, the processor may be configured to determine whether a discharge connector for supplying a voltage to the outside of a vehicle or a charge connector for supplying a voltage to the inside of the vehicle is connected to a vehicle insertion port by sensing a voltage of a PD (Proximity Detection) signal line, and determining whether a discharge start command is applied when the discharge connector is connected by sensing a voltage of a CP (Control Pilot) signal line.
Description
technical field [0001] The invention relates to a vehicle charge and discharge control device, a vehicle charge and discharge system including the charge and discharge control device, and a vehicle charge and discharge control method. Background technique [0002] A plug-in hybrid vehicle (PHEV) and an electric vehicle (EV) are charged by an external power source and used as a power source to drive the vehicle. The vehicle is connected with a power line, a CP (Control Pilot, communication) line and a PD (Proximity Detection (proximity detection)) line for charging by an external charging equipment (Electric Vehicle Supply Equipment, EVSE). [0003] like figure 1 As shown, the power line is connected from the power supply of the charging station system 20 (EVSE) to the On Board Charger (OBC) of the vehicle system 10 . The CP line is the channel for the EVSE and the vehicle to exchange information, and the EVSE control board is connected to the Vehicle Charge Management Syst...
