According to the power supply fault prevention system and the vehicle, a positive electrode internal connection pin of an external power supply wire harness connection socket is connected with the positive electrode input end of a direct-current high-low voltage converter, the negative electrode input end of the direct-current high-low voltage converter is grounded, and the positive electrode output end of the direct-current high-low voltage converter is connected with the positive electrode of a vehicle storage battery so as to supply power to the vehicle storage battery; the positive electrode of the vehicle storage battery is connected with the positive electrode external pin of the external power supply wire harness socket to form an external power supply loop for the vehicle storage battery to supply power to the high-voltage auxiliary drive controller; and the positive electrode output end of the direct-current high-low voltage converter is connected with the positive electrode internal pin to form an internal power supply loop for supplying power to the high-voltage auxiliary drive controller. Based on the system provided by the invention, when the external power supply wire harness socket fails, the internal power supply loop can still be used for conveniently and efficiently supplying power to the high-voltage auxiliary drive controller so as to provide required electric energy for the high-voltage auxiliary drive controller.
