Problems solved by technology

[0004] The purpose of the present invention is to provide a solar-based automotive air-conditioning power supply system and vehicle, to optimize the low-voltage power supply of the existing vehicle air-conditioning only through the on-board battery. Thus restricting and controlling the power consumption of the air conditioner, the stability of the power consumption of the air conditioner cannot be guaranteed, and finally the problem that the air conditioner cannot be used normally

[0005] In order to realize the power supply of solar energy to the air conditioner, and at the same time ensure the stability of the low-voltage power consumption of the air conditioner, optimize the low-voltage power supply of the existing vehicle air conditioner when it is only powered by the on-board battery, the power supply power is limited due to the power consumption requirements of the vehicle's power and safety. 1. To control the electricity consumption of air conditioners, the stability of the electricity consumption of air conditioners cannot be guaranteed, and finally lead to the problem that the air conditioners cannot be used normally. The present invention provides a power supply system for automobile air conditioners based on solar energy, including high-voltage batteries and battery packs. The high-voltage batteries pass through The high-voltage bus is used to supply power to connect the high-voltage electrical equipment of the air conditioner, and the battery pack is used to supply power to connect the low-voltage electrical equipment of the air conditioner through the low-voltage bus, and also includes a solar panel and a DC / DC converter connected to the high-voltage battery. The output end of the DC converter is connected to the low-voltage bus, the input end of the DC / DC converter is connected to the high-voltage bus, and the solar panel is connected to the low-voltage bus through a photovoltaic power generation controller
