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.

    本发明公开了一种车辆供电电路、设备及汽车,涉及汽车电源系统技术领域。车辆供电电路包括动力电池,包括多个依次连接的电池组;多个第一供电电路,各第一供电电路的输入端与对应的电池组的输出端连接,各第一供电电路的输出端均与第一供电端连接;第二供电电路,第二供电电路的输入端与动力电池的输出端连接,第二供电电路的输出端分别与第一供电端和第二供电端连接;蓄电池,蓄电池的输出端与第二供电端连接。本发明通过对各电池组的输出电源进行转换,获得多个供电电源;同时结合蓄电池为车辆中的各低压电器进行供电,从而避免供电异常导致各低压电器掉电,提高了车辆的安全性。
