The invention discloses a new energy automobile battery pack high-voltage electric appliance box, which comprises an upper cover and an electric appliance box main body, a high-power relay and a pre-charging relay are arranged in the electric appliance box main body, a wire harness for transmitting electric signals is arranged in the electric appliance box main body, the high-power relay adopts a horizontal relay, the horizontal relay is connected with the wire harness through a connector, and the pre-charging relay is connected with the wire harness. The pre-charging relay is a vertical relay, and the vertical relay is connected with the wire harness through an L-shaped connector. The height of a horizontal relay of the same specification is greatly reduced compared with that of a vertical relay, after an L-shaped connector is inserted, the height of a pre-charging relay is the same as that of a horizontal main relay and that of a quick-charging relay, the height of the whole high-voltage electric appliance box is reduced, and copper bar groups are arranged at the bottom of an electric appliance element, so that the width of the high-voltage electric appliance box is not increased; the height is reduced, the occupied space is reduced, and the technical problem that the space of a battery pack is limited due to the fact that a high-voltage electric appliance box is high and large in occupied space is solved.
本发明公开了一种新能源汽车的电池包高压电器盒,包括上盖和电器盒主体,所述电器盒主体内设有大功率继电器和预充继电器,电器盒主体内设有传递电信号的线束,所述大功率继电器采用卧式继电器,卧式继电器通过连接器连接线束,预充继电器为立式继电器,立式继电器与线束之间通过L型连接器连接。同样规格的卧式继电器比立式继电器的高度大大降低,并且插上L型连接器后,预充继电器的高度与卧式的主继电器和快充继电器高度相同,将整个高压电器盒的高度降低,铜排组均设置在电器元件的底部,使得高压电器盒的宽度不会增加,高度降低,减小占用空间,解决了高压电器盒的高度较高,占用空间大,导致电池包空间紧张的技术问题。
