The invention discloses a vehicle power supply circuit, equipment and an automobile, and relates to the technical field of automobile power supply systems. The vehicle power supply circuit comprises a power battery which comprises a plurality of battery packs connected in sequence; multiple first power supply circuits, wherein the input end of each first power supply circuit is connected with the output end of the corresponding battery pack, and the output end of each first power supply circuit is connected with the first power supply end; a second power supply circuit, wherein the input end of the second power supply circuit is connected with the output end of the power battery, and the output end of the second power supply circuit is connected with the first power supply end and the second power supply end; and a storage battery, wherein the output end of the storage battery is connected with the second power supply end. According to the invention, the output power supply of each battery pack is converted to obtain a plurality of power supplies; meanwhile, the storage battery is combined to supply power to each low-voltage electric appliance in the vehicle, so that power failure of each low-voltage electric appliance caused by abnormal power supply is avoided, and the safety of the vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of automobile power supply systems, in particular to a vehicle power supply circuit, equipment and an automobile. Background technique [0002] The power supply system of new energy vehicles is divided into a high-voltage power supply system and a low-voltage power supply system. Among them, the power supply objects of the low-voltage power supply system mainly include vehicle-mounted low-voltage electrical appliances, such as various controllers (power management controllers, vehicle controllers, motor controllers, etc.) etc.), instruments, displays, communication modules, etc. However, at present, when the power supply of the low-voltage power supply system is abnormal, if the vehicle is not allowed to be powered off (such as driving at high speed), the low-voltage electrical appliances in the vehicle will be abnormally powered off, causing potential safety hazards in the vehicle.
