Abstract: A drive apparatus and an electric vehicle are provided to implement fault monitoring functions of two control chips when one watchdog chip is configured. The drive apparatus includes a first control chip, a second control chip, a first drive circuit, a second drive circuit, a watchdog chip, and a reset shutdown circuit. The first drive circuit generates a drive signal of a first inverter. The second drive circuit generates a drive signal of a second inverter. The first control chip and the second control chip perform fault monitoring on each other.
