The invention discloses a new energy automobile battery pack heating control system, and belongs to the field of new energy automobiles, the new energy automobile battery pack heating control system comprises a battery pack, an air conditioner module, a PTC (Positive Temperature Coefficient), a water pump, a vehicle control module, a cooling water path system and a control valve, the battery pack is in signal but not limited to signal connection with the vehicle control module, and the vehicle control module can set a heating threshold value; the battery pack can transmit the real-time battery cell temperature to the whole vehicle control module through the temperature detection assembly, and when the real-time battery cell temperature reaches a heating threshold value, the whole vehicle control module sends a signal to the control valve. A battery pack quick-charging and quick-heating mode is added, under the condition of quick charging, a vehicle control unit can be connected with an air conditioner warm core loop in series according to the cell temperature of the battery pack for auxiliary heating, the temperature of the battery pack is quickly increased, energy consumption loss is effectively reduced, on the basis that additional PTC equipment is not added and an air conditioner system is not affected, the temperature of the battery pack is quickly increased, and the service life of the battery pack is prolonged. The charging efficiency is improved and the energy loss is reduced.
