[0018] The specific implementation mode of the utility model will be further explained in detail by comparing the drawings and describing the optimal embodiment.

[0019] Figure 1 The structure schematic view of the new energy automobile reservation travel system provided by the utility model embodiment, for the convenience of explanation, only shows the part related to the utility model embodiment, and the system comprises:

[0020] The mobile terminal is in communication connection with the vehicle end through T-BOX;

[0021] The vehicle end comprises: the IHU host, the battery management system BMS in communication connection with the IHU host and the vehicle-mounted OBC charger;

[0022] The mobile terminal sends the reservation time to the vehicle end through the T-BOX, the IHU host reads the currently set reservation time, when the time length of the reservation time from the current time is greater than the set time threshold (30 minutes), the vehicle OBC charger is in the charging state, and the battery pack is lower than the set temperature threshold, the IHU host sends the battery pack heating request to the battery management system BMS, the battery management system BMS heats the power battery based on the battery pack heating request, and the heating of the power battery is stopped when the temperature of the power battery reaches the set temperature.

[0023] When the time length of the reservation time from the current time is less than the set time threshold, the IHU host does not send the battery pack heating request to the battery management system BMS, and the battery management system BMS does not start the power battery heating function, so that the power battery heating function is started only when the time length of the reservation time from the current time is relatively long, and the power battery is heated in advance when the battery pack temperature is too low, so that the performance of the power battery is improved, and the cruising range is increased; in addition, the battery pack heating function is started only when the vehicle is charging, so that the risk of power reduction of the battery pack caused by the battery pack heating is reduced, and the cruising range of the electric vehicle is ensured.
