The invention relates to a vehicle power supply circuit, a vehicle power supply control method and a vehicle. The vehicle power supply circuit (100) comprises a first battery pack (10) connected with a high-voltage load (40) of the vehicle and used for supplying power to the high-voltage load; the second battery pack (20) is connected with a driving system of the vehicle and used for supplying power to the driving system (50), and the rated voltage of the first battery pack is smaller than that of the second battery pack; and the buck-boost circuit (30) is connected between the first battery pack and the second battery pack. In the scheme, the two battery packs can adapt to different working conditions and adopt different power supply strategies through the connected buck-boost circuit while exerting respective advantages, and the functionality is considered. The vehicle power supply circuit provided by the scheme is simple in structure, fully utilizes the characteristics of the battery pack, and is high in expandability.
