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.

    本发明公开了一种新能源汽车电池包加热装置及控制方法,涉及汽车制造技术领域。包括整车控制器,所述整车控制器接收电池包控制器发送来的电池包内部温度,当电池包需要加热时,所述整车控制器驱动水泵转动,所述水泵带动冷却液在所述电池包和电池包加热器内循环流动,同时所述整车控制器也驱动继电器吸合,所述继电器吸合后,控制电池包的电源与所述电池包加热器接通,所述电池包加热器开始工作,所述电池包加热器使所述冷却液的温度升高,并将热量带给电池包热交换板,从而给所述电池包加热。本发明可以解决现有技术存在的要么没有温度保护,要么价格高昂增加生产成本的问题。
