The invention relates to the technical field of vehicle power supply control, and discloses a vehicle redundant power supply circuit and method, and the vehicle redundant power supply circuit comprises a power conversion circuit and a rectification filter circuit. The power conversion circuit is electrically connected with the power battery, the power conversion circuit is electrically connected with the rectification filter circuit, and the rectification filter circuit is electrically connected with a vehicle weak current component; the power conversion circuit is used for receiving a first output electric signal of the power battery and carrying out inversion and voltage reduction on the first output electric signal to obtain an alternating current electric signal; the rectifying and filtering circuit is used for rectifying and filtering the alternating-current electric signal to obtain a second output electric signal matched with the voltage of the vehicle weak-current component and transmitting the second output electric signal to the vehicle weak-current component, and the vehicle weak-current component at least comprises one of a battery management system and a vehicle sensor. The reliability of normal use of the vehicle weak current component is improved, and the risk of power shortage of the power battery is reduced.
