The utility model provides a special vehicle power supply system. The special vehicle power supply system comprises an alternating-current power supply and a direct-current power supply which are arranged to satisfy power demands of vehicle-mounted alternating-current and direct-current load equipment, wherein the direct-current power supply consists of a storage battery pack, an external alternating-current power supply for charging the storage battery pack, a vehicle-equipped power generator and a solar bulb group, and is used for supplying power to vehicle direct-current load equipment and alternating-current to direct-current conversion equipment; the alternating-current power supply consists of an introduced external power supply, a vehicle-mounted larger-power direct-current to alternating-current converter and a vehicle-mounted smaller-power direct-current to alternating-current converter which are mutually standby. Through automatic monitoring and switching, a proper operation manner can be selected according to the actual load situation, so as to improve the utilization rate of the vehicle-mounted equipment and minimize the self-consumption of the direct-current to alternating-current conversion equipment.
