The invention discloses an automatic awakening dormancy device and method, a power supply and a rail transit vehicle, and relates to the technical field of locomotive power supply control. The device comprises a power input switch, a control module, a first relay, a second relay and a contactor, a first end of the power input switch is connected with an output end of a power supply, a second end of the power input switch is connected with a power input end of the control module, and a first output end and a second output end of the control module are respectively connected with coils of the first relay and the second relay. A coil of the contactor, a normally open contact of the first relay and a normally closed contact of the second relay form a series branch, the series branch is connected with the second end of the power input switch, and the first normally open contact 1 of the contactor is connected to the two ends of a power output switch of the power supply in parallel. And a second normally open contact of the contactor is connected in parallel with two ends of the normally open contact of the first relay. According to the invention, the automatic awakening and dormancy functions of the load are realized.
