The invention relates to a battery low-temperature reservation heating control method for an electric vehicle. Compared with the prior art, the defect that no reservation heating control scheme of theelectric vehicle is available is solved. The battery low-temperature reservation heating control method provided by the invention comprises the following steps: obtaining a reservation heating operation: obtaining, by a remote intelligent terminal, a battery reservation heating operation request through a mobile phone APP; calculating a heating time of a heating mode: calculating, by the remote intelligent terminal, the required heating time; preheating the battery: judging, by a full vehicle controller, a charging gun state; and completing the heating mode: judging, by the remote intelligentterminal, whether the battery reaches a predetermined temperature. By adoption of the battery low-temperature reservation heating control method provided by the invention, the preheating of the vehicle-mounted battery is reserved in a low temperature environment in advance, so that the service life of the battery is effectively prolonged.
