Battery enclosure technologies encompass several core dimensions, including design, materials, and protection. Key technical aspects are outlined below:
Structural Design Technology
Designs must meet requirements for high strength and rigidity, efficient heat dissipation, IP67-rated sealing and waterproofing, and modularity for easy maintenance. They must withstand impact and vibration while preventing battery overheating or short circuits caused by water ingress.
Material Application Technology
Materials include steel, aluminum alloys, SMC composites, and fiberglass (FRP), selected to balance needs such as lightweighting, corrosion resistance, electrical insulation, and flame retardancy depending on the specific application.
Safety and Protection Technology
Features include fire and thermal insulation, explosion-proof pressure relief, electromagnetic shielding, and BMS real-time monitoring. These measures effectively mitigate the risk of thermal runaway and ensure the stable operation of the battery system.
Manufacturing Process Technology
Processes such as friction stir welding, airtightness testing, and CMM (Coordinate Measuring Machine) precision verification are employed to ensure high welding quality and sealing performance.
