The new energy power battery shells on the market are mainly square in shape, usually made of 3003 aluminum alloy using hot rolled deep drawing process. Depending on the design requirements of the power battery, the thickness and width can be customized.
Chalco's production of power battery aluminum trays mostly uses 6-series 6061 aluminum plate as the raw material for battery aluminum trays, which can meet the characteristics of high precision, corrosion resistance, high temperature resistance, and impact resistance to protect the battery core.
Glass fibre top covers, bottom covers and impact protection plates can provide a more cost-effective material for battery cases. The most challenging factor is TRP, as the combustion needs to be contained in the box. Then there are EMI, thermal and electrical isolation and mechanical issues of drive loads, crashes and impacts to consider.
The majority of long-range BEVs in production use aluminum as the main material for the battery enclosure. (Constellium) Mass reduction is the main driver behind aluminum battery enclosures, but thermal requirements prove challenging for the lightweight material.
And public statements made by the company regarding the structural battery pack expected to come from Tesla’s Berlin plant indicate the upper and lower covers are steel. Aluminum battery enclosures typically deliver a weight savings of 40% compared to an equivalent steel design.
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.
