Aluminum and low-alloy steels are the traditional choice for battery housings. But these materials can be restrictive in terms of both design and manufacturing flexibility and have limited safety potential. Stainless steels and their associated construction and manufacturing concepts can help address these challenges.
Stainless steel can save weight and improve the crash resistance of EV battery housings. Crucially, it also provides the heat resistance essential to ensure passenger safety in the event of a fire. The general requirement is to contain a fire for a period of up to 10 minutes to enable the safe evacuation of vehicle occupants.
Outokumpu automotive experts has compiled a guide for automotive and battery system designers keen to explore the possibilities of using high performance stainless steels for EV battery casings. Interested?
Stainless steel concept for an EV battery compartment. Li-ion modules for EVs generate a significant amount of heat inside the sealed battery housing. In the event of damage, the liquid coolant must not come into direct contact with the modules.
