The invention relates to a power supply circuit, a power supply system and a vehicle, and relates to the technical field of power supply. Comprising a first battery pack, a second battery pack, a conduction piece and a current converter, one end of the conduction piece is connected with the first battery pack and the second battery pack, and the other end of the conduction piece is connected with the current converter; the conduction piece is used for conducting a loop between the first battery pack and the current converter and/or a loop between the second battery pack and the current converter according to a voltage relationship between the first battery pack and the second battery pack; and the current converter is used for converting the current output by the first battery pack and/or the second battery pack and providing the converted current to a load. By using the power supply circuit provided by the invention, the electric quantity of the first battery pack and the electric quantity of the second battery pack can be automatically balanced under the condition that a controller is not used.
