The battery box consists of four primary structural pieces: top cover, bottom cover, internal structure, and side impact crash protection structure. In the image below, the primary load-bearing structural components are identified as the crash structure and the battery frame. Read Success Stories
One plug-in hybrid EV built in China is already using a thermoplastic polypropylene compound instead of aluminium for its battery case cover, providing savings in weight. Other EVs now in production around world are using several thermoplastic materials for components such as cell carriers and housings, battery modules and battery enclosures.
And the battery enclosure’s tray is made from steel, drawn to form completely vertical (90°) side walls that optimise the space for the battery pack. The tray also prevents the battery cells from leaking into the environment during and after a crash. What is the estimated weight for the entire battery enclosure?
The main structure of the battery pack box includes the upper-pressure cover, the upper-pressure rod, the lower box body of the battery pack, the inner frame, the lifting lug, the battery module, the single battery, and other structures.
The battery box is a pure incremental component in new energy vehicles, and the value of a single vehicle is about 3,000 yuan. The battery box is mainly composed of an upper cover and a lower case, which is the “skeleton” of the power battery module, and is used to protect the battery PACK against external impact, dustproof and waterproof.
The choice of materials used for a battery case has to cover a wide range of performance issues. Replacing steel or bonded aluminium with thermoplastics or glass fibre composites is offering lighter cases and more options for increasing the energy density by using larger components that can be more easily assembled.
