The invention provides a railway vehicle storage battery input control circuit and a railway vehicle, the circuit comprises a storage battery pack, a storage battery management system, an input control circuit, an auxiliary holding circuit and a storage battery input circuit, the input control circuit comprises an input contactor branch and a state relay branch which are connected in parallel, the input contactor branch comprises an input contactor, the state relay branch comprises a state relay, the auxiliary holding circuit comprises an auxiliary normally open contact and an auxiliary holding relay which are connected in series, the storage battery input circuit comprises an input normally open contact, and the input contactor is used for controlling the auxiliary normally open contact and the input normally open contact to act. The storage battery management system is connected with the storage battery pack and used for controlling the state relay to be powered off under the condition that the storage battery pack breaks down. The method and the device are used for overcoming the defect that batteries are damaged due to the fact that a storage battery pack is rationally put into use without a detection state in the prior art, and safe putting and operation of the storage battery pack are achieved.
