The invention provides an electric vehicle battery heat preservation device which comprises a battery box and a battery module and further comprises a heat insulation box and a heating tower, a heat conduction chamber is arranged between the heat insulation box and the battery box, the heating tower is connected with the heat conduction chamber through a pipeline, the heat insulation box comprises a plurality of heat insulation plates, and each heat insulation plate is hollow to form a closed cavity. A first supporting body and a second supporting body are fixedly arranged on the side edge of the closed cavity, an extraction opening is formed in the heat insulation plate, the closed cavity is subjected to air extraction through the extraction opening to form a vacuum cavity, and heat conduction liquid and a heating piece are arranged in the heating tower. According to the heat preservation device for the battery of the electric vehicle, the heat insulation box is used for preserving heat of the battery module, the heat conduction liquid heated by the heat conduction piece circularly enters and exits from the heat conduction chamber to heat and preserve heat of the battery module, and meanwhile, the unheated heat conduction liquid circularly enters and exits from the heat conduction chamber to cool the battery module, so that the battery module can still be normally used in a high-temperature environment or a low-temperature environment.
本发明提供了一种电动汽车电池保温装置,包括电池箱和电池模组,还包括隔热箱和加热塔,隔热箱与电池箱之间设有导热室,加热塔通过管道与导热室连接,隔热箱包括多块隔热板,每块隔热板中空形成一密闭空腔,密闭空腔的侧边固设有第一支撑体和第二支撑体,隔热板上开设有抽气口,密闭空腔通过抽气口抽气为真空腔,加热塔中设置有导热液和加热件。本发明提供的电动汽车电池保温装置,利用隔热箱对电池模组进行保温,以及通过被导热件加热后的导热液循环进出导热室,来对电池模组进行加热保温,同时,未加热的导热液循环进出导热室,也能对电池模组起到冷却的作用,使电池模组无论在高温还是低温环境中仍能正常使用性能。
