The invention discloses a new energy automobile battery pack heating device and a control method, and relates to the technical field of automobile manufacturing. The device comprises an automobile control unit; the automobile control unit receives the internal temperature of a battery pack sent by a battery pack controller; when the battery pack needs to be heated, the automobile control unit drives a water pump to rotate, the water pump drives a cooling liquid to circularly flow in the battery pack and a battery pack heater, and meanwhile, the automobile control unit also drives a relay to beclosed; after the relay is closed, the power supply of the battery pack is controlled to be connected with the battery pack heater; the battery pack heater starts to work; the battery pack heater enables the temperature of the cooling liquid to rise, and takes heat to a battery pack heat exchange plate, so as to heat the battery pack. With the new energy automobile battery pack heating device andthe control method of the invention adopted, the problems of unavailability of temperature protection, high cost and increased production cost in the prior art can be solved.
