| description | The invention discloses a battery pack heating control method and system. The method comprises the steps that: when it is detected that a vehicle is started, a gear state is monitored; when the gear is switched into a D gear, the temperature of the cell of a battery pack is acquired; if the temperature is lower than the minimum value of a preset interval value, the running mode of the vehicle is obtained, and if the running mode is a Normal mode or an ECO mode, a heater control instruction is generated; if a received feedback instruction is a closing instruction or an undetermined instruction, the current gear state is queried after a preset time interval; and if the obtained current gear is not a P gear, the heater control instruction is generated again; and if the received feedback instruction is a starting instruction, a heater is controlled to be started. With the method adopted, an intelligent processing mode is achieved for the heater of the electric vehicle, on-off control of the heater is humanized, a |
