ABSTRACT:
A power supply cut off apparatus is provided in which a DC power supply voltage supplied from a main power supply is converted into an AC current by an inverter of a driver, and brushless DC motors are driven by the converted current, during normal operation. In the normal operation, an abnormal state of an electrical vehicle, such as collision, is detected by a plurality of sensors, and collision detection signals are supplied to a diagnosis section. The diagnosis section determines whether an actual collision has occurred or detects a state in which a collision is unavoidable on the basis of the collision detection signals and, as a result, supplies a power cutoff signal to a circuit breaker. The circuit breaker cuts off the output of power supply voltage from the main power supply to the driver using relays.
