Abstract

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.

Description

technical field [0001] The invention relates to the field of battery packs for electric vehicles, and more specifically, relates to a battery pack design for electric vehicles. Background technique [0002] New energy and intelligence are the two directions of future automobile development. In recent years, the number of electric vehicles in China has grown rapidly, and electric vehicles have become the choice of tens of millions of families to replace fuel vehicles; at the same time, new energy buses have also occupied an increasing market for buses. In the future development, electric vehicles still have a huge room for growth. However, due to deficiencies in the prior art, there are still many deficiencies in the development of electric vehicles. Among them, battery problems have become one of the main factors affecting the development of electric vehicles. Due to the unstable condition of the battery itself and the complex working environment of the vehicle battery, t...
