The embodiment of the invention discloses a relay protection circuit, a generator and a generator relay protection method; wherein the relay protection circuit comprises a DC input end, a controller and at least two charging circuits, and each charging circuit comprises a voltage regulation module, a relay and a charging interface; the direct-current input end, the voltage regulating module, the relay and the charging interface are connected in sequence; the input end of the relay in each charging circuit is connected with the output end of the voltage regulating module, a plurality of second output ends of the relay are connected with the charging interfaces of other charging circuits in a one-to-one correspondence mode, and the controller is used for obtaining the voltage value of a battery connected into the charging circuit. The voltage value of the output end of the voltage regulating module, without the battery connected into the charging circuit, is regulated to be the voltage value of the battery, then the input end of the relay, without the battery connected into the charging circuit, is controlled to be connected to the second output end, and at this time, the voltage difference between the two ends of the relay is small, ignition adhesion cannot occur when the relay is closed and the relay closing is protected. Therefore, the service life of the relay is prolonged.
