This application discloses a supercharging power supply circuit and method for vehicles, belonging to the field of circuit technology. The battery pack module includes a low-voltage battery pack and a high-voltage battery pack, with rated voltages of a first voltage value and a second voltage value.

The application discloses a superconducting charging cable of fault current limiting type, and mainly solves the problems that existing superconducting cables cannot be used for bidirectional direct-current high-power charging and have complex structures. The superconducting charging cable comprises a cable framework and liquid nitrogen passage (1), a composite conductor layer (2) and a thermal insulation shell (3). The cable framework supports the composite conductor layer and the thermal insulation shell. The composite conductor layer is composed of inner and outer superconducting tape layers and inner and outer fault current limiting stabilizing layers, and is wrapped on the cable framework. The inner composite conductor layer and the outer composite conductor layer are separated by using an intermediate layer insulating bushing, so that the bidirectional direct-current charging function of the superconducting cable is realized. The fault current limiting stabilizing layer is armored on the superconducting tape layer, so that the fault current limiting function of the superconducting cable is realized. The thermal insulation shell is wrapped on the outer liquid nitrogen bellows, so that the heat leakage of the cable body to the outside is greatly reduced. The superconducting charging cable has a compact structure, does not need to use a fault current limiter, and can be used for connecting electrode terminals to perform high-power direct-current fast charging on electric vehicles.
