The invention discloses a vehicle power supply circuit, equipment and an automobile, and belongs to the technical field of automobile power supply systems. The vehicle power supply circuit comprises a power battery, a first power supply circuit, a second power supply circuit and a fusing element. The input end of the first power supply circuit is connected with the output end of the power battery, and the output end of the first power supply circuit is connected with a first power supply end; the input end of the second power supply circuit is connected with the input end of the first power supply circuit, and the output end of the second power supply circuit is connected with the first power supply end and a second power supply end; and the fusing element is arranged between the input end of the first power supply circuit and the input end of the second power supply circuit. According to the vehicle power supply circuit of the invention, the output power supply of the power battery is converted, so that a plurality of power supplies can be obtained; the first power supply circuit is arranged on the inner side of the fusing element, thus, after the fusing element is disconnected, the first power supply circuit can still output a low-voltage power supply, power supply of part of low-voltage electric devices of a vehicle is guaranteed, 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、第一供电电路、第二供电电路和熔断元件;第一供电电路的输入端与动力电池的输出端连接,第一供电电路的输出端与第一供电端连接;第二供电电路的输入端与第一供电电路的输入端连接,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;熔断元件设置于第一供电电路的输入端与第二供电电路的输入端之间。本发明通过对动力电池的输出电源进行转换,获得多个供电电源;将第一供电电路设置于熔断元件内侧,使得熔断元件断开后,第一供电电路仍然能够输出低压供电电源,保证了车辆部分低压电器件的供电提高了车辆的安全性。
