The invention provides a battery pack of a new energy electric vehicle. The battery pack comprises a battery box, a battery supporting plate, a supporting spring and a cooling fan, the battery supporting plate is placed in the battery box, and the double-layer sandwich structures which are made of aluminum alloy and are provided with the hollow cores are separately arranged at the outer sides of the upper surface and the lower surface of the battery box. The head of the supporting spring is glued on the battery supporting plate, and the tail of the supporting spring is welded on a supporting bolt. The supporting bolt is fixedly connected to a threaded hole in the battery box, the threaded hole has a certain depth, and the supporting bolt adjusts the height of the supporting spring by rotating, so that the height of the battery accommodating space of the battery supporting plate is adjusted. The cooling fan is placed outside one side face of the battery box and is connected with a storage battery of the vehicle through a cable. The battery pack is good in energy absorption effect and shock absorption effect, has flame retardant performance and meanwhile, adapts to various batteries,and the single battery is convenient to maintain.

    本发明提供了一种新能源电动汽车电池包,包括:电池箱、电池支撑板、支撑弹簧和散热风扇;所述电池支撑板放置在电池箱内部;所述电池箱的上表面和下表面外侧分别具有铝合金制的具有中空夹心的双层三明治结构;所述支撑弹簧头部胶接在电池支撑板上,尾部焊接在支撑螺栓上;所述支撑螺栓固定连接在电池箱体上的螺纹孔上;所述螺纹孔具有一定的深度,支撑螺栓通过旋转调节支撑弹簧的高度,进而调节电池支撑板的电池容置空间的高度;所述散热风扇放置在电池箱的其中一个侧面外,并且通过电缆连接汽车的蓄电池。上述的电池包吸能效果好,减震效果好,具有阻燃性能,同时适配多种电池,并且方便单个电池维修。
