Two-way Power Supply Apparatus of Electric Vehicle for Smart Grid and Two-way Power Supply Method Using the Same

摘要

The present invention relates to a smart grid capable of minimizing the maintenance cost of an electric vehicle and facilitating electric power supply and demand problems of an electric power supplier by charging an electric vehicle battery according to a set standard using a smart grid or by supplying electric power of a battery to a grid. The present invention relates to a bidirectional power supply apparatus for a vehicle and a bidirectional power supply method using the same. To this end, an electric vehicle bidirectional power supply device for a smart grid according to the present invention comprises: a battery; A BMS (Battery Management System) for measuring the SOC (State of Charge) of the battery; An MCU (Motor Control Unit) including a controller and an inverter and controlling the operation of the motor; A determination unit for determining whether the driver is operating in the smart mode; A grid power supply unit for supplying the output current of the inverter to a grid connected to the electric vehicle by an instruction of the determination unit in the smart mode; The present invention provides an electric vehicle bi-directional power supply for a smart grid.
