What are the key elements of a battery case in an EV car?

Compared to those in traditional petrol vehicles, EV cars' battery is much heavier, larger and more crucial. It is not only to generate electricity for starting the engine and some less important system like sound system and lights, but also to provide the power for propulsion. Therefore,  an EV car's battery case must be stable enough to guarantee more protection. First of all, it must be high-strength to undertake heavy impact, protecting the battery inside. Secondly,  excellent heat resistance is required to prevent the vehicle fire in an accident to spread into the battery which may lead to an explosion or toxic gas with great danger. Besides, designers pursue the light-weighting of the battery case. A lighter battery case can lead to less energy consumption and longer endurance ranges.

What are Battery Boxes of EV Made of?

Mostly made of cold-rolled mild steel. It is a cost-effective material that has comparatively less strength and hardness, and good plasticity and toughness. Therefore, its cold formability is outstanding, and is easy for hemming, bending and stamping.  Also, it has good weldability.
