HIGH VOLTAGE SHUT DOWN SYSTEM AND METHOD FOR ELECTRIC VEHICLE

摘要

A high voltage shut down system and method for an electric vehicle are provided, which perform a high voltage shut down function in connection with a collision detection signal (airbag expansion signal) generated from an airbag controller even when a vehicle is being charged. The high voltage shut down system a third power supply controller which is in an operable state for transmitting power when the vehicle starts and is charged. An airbag control unit is operated by receiving power through the third power supply controller, and is configured to generate an airbag expansion signal when detecting an occurrence of a collision of the vehicle. A high voltage controller is configured to perform a high voltage shut down function in response to receiving the airbag expansion signal.
