The invention relates to the technical field of vehicle energy, in particular to a solar energy automobile air conditioner power supply system and a vehicle. The vehicle comprises an air conditioner and the air conditioner power supply system. The air conditioner comprises air conditioner high-voltage electric equipment and air conditioner low-voltage electric equipment. The air conditioner powersupply system comprises a high-voltage battery, a solar cell panel and a DC/DC converter which is connected with the high-voltage battery. The high-voltage battery is connected with the air conditioner high-voltage electric equipment through high-voltage bus power supply. The output end of the DC/DC converter is connected with the air conditioner low-voltage electric equipment through low-voltagebus power supply. The input end of the DC/DC converter is connected with the high-voltage bus. The solar panel is connected with the low-voltage bus through a photovoltaic power generation controller.The purpose of supplying electricity to the air conditioner by solar energy is realized. The problems that when only a vehicle-mounted battery is used for supplying electricity during low-voltage power supply of an existing vehicle air conditioner, energy is consumed very fast, so that the fuel economy of the whole vehicle or the vehicle driving mileage is influenced are solved.
