Abstract
A method of operating an EV in one of various states provides an inverter control system having a high voltage circuit powered by a high DC voltage power source; a low voltage circuit powered by a low DC voltage power source that is substantially less than the voltage of the high voltage power source, the low voltage circuit being configured to power a microcontroller; and an inverter circuit having a plurality of high side switches and a plurality of low side switches, the inverter circuit being configured to deliver AC power to a traction motor. Upon powerup of the high voltage circuit and with the low voltage circuit being unpowered, the method establishes an emergency tow state with each of the high side switches and each of the low side switches being open permitting the EV to be towed without damaging the motor.
