Battery cases for electric vehicles are structural components designed to encase and protect power battery packs, typically made from aluminum alloys, high-strength steel, magnesium alloys, or composite materials, offering high strength, corrosion resistance, effective heat dissipation, and sealing performance. These cases provide mechanical support and protection against impacts, vibrations, moisture, and dust, while integrating thermal management systems, wiring interfaces, and safety devices to ensure stable temperature control and electrical safety during charging and discharging. The design of EV battery cases must balance lightweight construction, mechanical strength, airtightness, and serviceability to enhance driving range, crash safety, and overall energy efficiency, making them essential for battery electric vehicles, plug-in hybrid vehicles, and energy storage systems.
