组件规格

定义
A structural component designed to contain, protect, and thermally manage battery cells within electric vehicle battery systems. It provides mechanical integrity, electrical insulation, and environmental sealing while facilitating thermal management through integrated cooling channels.
工作原理
The battery enclosure functions as a protective barrier that isolates battery cells from external impacts, moisture, and contaminants while maintaining structural stability. It incorporates thermal management systems (liquid cooling plates or air channels) to regulate operating temperatures, and includes safety features like venting mechanisms for gas release during thermal runaway events.
材料
Aluminum alloy (typically 6000 series) for lightweight structural applicationsor advanced composites (carbon fiber reinforced polymers) for high-performance vehicles. Internal components may include thermal interface materialsinsulating foamsand flame-retardant coatings.
Weight
15-40 kg depending on material and size
IP Rating
IP67 or higher for water/dust ingress protection
Dimensions
Varies by vehicle platform (typically 1500-2500mm length)
Crush Resistance
≥ 100 kN for safety compliance
Thermal Conductivity
150-200 W/m·K for aluminum enclosures
Operating Temperature
-40°C to +85°C
标准
ISO 26262ISO 12405SAE J2929UN/ECE R100GB/T 31467

常见问题

What are the key safety requirements for battery enclosures?

Battery enclosures must prevent thermal runaway propagation, contain electrolyte leaks, provide crash protection, and include pressure relief mechanisms. They must meet UN/ECE R100 and ISO 26262 standards for functional safety.

How do battery enclosures manage heat?

Through integrated cooling channels (liquid cooling plates or air channels), thermal interface materials, and strategic material selection to conduct heat away from cells while maintaining uniform temperature distribution.
