The embodiment of the invention provides a hybrid redundant power supply system and a vehicle. The system comprises a 12V power supply network, a 48V power supply network and a bidirectional DCDC, the 12V power supply network comprises a low-voltage power distribution unit, the low-voltage power distribution unit is integrated with a 12V safety switch, the 12V safety switch is used for 12V power supply redundant power supply and meets the function safety ASIL-D requirement, the 48V power supply network comprises a medium-voltage power distribution unit, the medium-voltage power distribution unit is integrated with a 48V safety switch, the 48V safety switch is used for 48V power supply redundant power supply, and the bidirectional DCDC is connected with the medium-voltage power distribution unit. And the bidirectional DCDC is connected in series between the 12V power supply network and the 48V power supply network, and is used for mutual standby power supply between the 12V power supply network and the 48V power supply network. On the basis of meeting the power supply requirement, the complexity and the failure rate of the power supply system are reduced, and the expansibility and the compatibility are improved.
