EV Car Battery Shell

The EV car battery shell is a critical protective enclosure designed specifically for lithium battery modules in electric vehicles, providing three essential functions: mechanical protection against impacts, electromagnetic interference shielding with ≥60dB effectiveness, and thermal runaway containment for safety. Manufactured to comply with stringent international standards including UN38.3 and China's GB38031-2020, it serves as the first line of defense for battery systems in various operating conditions.

 

 

1. High-Strength Lightweight Construction
The EV car battery shell utilizes aerospace-grade 3003-H14 aluminum alloy, offering 25% better formability than standard grades while maintaining 150MPa tensile strength. Its rib-reinforced design achieves optimal weight distribution, reducing overall vehicle energy consumption by up to 8% compared to steel enclosures.

 

2. Enhanced Thermal Management
Our pack aluminum housing features 3003-H14's superior thermal conductivity (209W/m·K), with integrated cooling fins that lower battery temperatures by 15°C during fast charging. The material's -40°C to 150°C operational range ensures reliability in extreme climates.

 

3. Corrosion-Resistant Protection
The battery aluminum housing employs 3003-H14's natural oxidation layer, passing 2000h salt spray tests without coatings. Optional anodizing provides extra protection for coastal applications, while maintaining 100% recyclability.

 

 

Material Preparation	Deep Drawing	Trimming and Deburring	Ultrasonic Cleaning	Surface Treatment
Select high-grade aluminum alloy sheets, same as those used for pack aluminum housing, ensuring thickness uniformity for subsequent processing.	Use precision molds to perform deep drawing on the aluminum sheet, shaping it into the initial form of aluminum battery box cover , with strict control of forming parameters.	Remove excess edges and burrs from the drawn shell, ensuring smoothness, which is also a key step in manufacturing battery aluminum housing.	Put the shell into an ultrasonic cleaning tank to eliminate oil stains and impurities, a standard process for automotive battery aluminum case.	Apply anti-corrosion coating to enhance durability, similar to the process for power battery shell.

 

 

1. Autonomous Driving Systems

The power battery shell is engineered for self-driving vehicles, featuring EMI shielding (>65dB) to protect sensitive sensors and AI processors. Its structural design meets autonomous vehicle crash standards (SAE J2464), while the 3003-H14 aluminum alloy provides 20% better energy absorption than conventional materials.

 

2. Electric Aviation Applications
Our pack aluminum housing solutions are specifically designed for eVTOL aircraft batteries, delivering a remarkable 40% weight reduction compared to titanium while meeting stringent fireproof certification (FAR 25.853). The housing maintains exceptional pressure stabilization performance even at 10,000ft altitude, ensuring reliable power delivery for next-generation electric aviation systems.

 

3. Marine Electrification
The battery aluminum housing provides complete protection for hybrid and electric marine vessels, featuring outstanding 5000-hour saltwater corrosion resistance (ASTM B117 certified), intelligent anti-condensation ventilation systems, and full compliance with DNV-GL marine certification standards - making it the ideal choice for harsh maritime environments.

 

 

Our EV car battery shell has earned consistent praise from global clients for its exceptional durability and precision engineering. Automotive manufacturers particularly value its superior thermal management and corrosion resistance, while energy storage system providers commend the perfect waterproof performance and structural reliability. The product's competitive edge lies in its aerospace-grade materials and customized solutions that meet diverse application requirements.
