Circuit for protecting battery for electric vehicle and driving method thereof
A circuit for protecting a battery for an electric vehicle includes a high voltage battery configured to output a DC voltage, an inverter configured to selectively receive the DC voltage from the high voltage battery and invert the DC voltage into an AC voltage when the inverter receives the DC voltage, a relay disposed between the high voltage battery and the inverter and configured to selectively block the DC voltage from the high voltage battery to the inverter, and a battery management system including a microchip configured to output a main relay control signal for controlling the relay. The battery management system is configured to receive the DC voltage from the high voltage battery, and output a voltage relay control signal controlling the relay separately from the control by the microchip.
