Frequently Asked Questions about EV Battery Enclosures

What materials are typically used in Haiyan Metal's battery enclosures?
We primarily use high-strength aluminum alloys and advanced steel grades.
How do your enclosures ensure the safety of the battery pack?
Our enclosures are engineered with multiple safety features:
  • Robust structural integrity to contain thermal events.
  • Effective sealing against moisture and contaminants.
  • Integrated thermal management channels to regulate temperature.
  • Crashworthiness designed to protect cells from impact damage.
Are your enclosures compatible with different battery cell formats?
Yes, our design and manufacturing process is flexible. We can produce enclosures tailored to various cell formats, including:
  • Prismatic cells
  • Cylindrical cells (e.g., 21700, 4680)
  • Pouch cells
We work with clients to customize the internal structure accordingly.
What is the development process for a custom battery enclosure?
The process involves several key stages to ensure a perfect fit and function:
  1. Requirement Analysis: We discuss your specific needs for performance, size, and integration.
  2. CAD Design & Simulation: We create a 3D model and run simulations (e.g., structural, thermal).
  3. Prototyping: A physical prototype is built for validation.
  4. The prototype undergoes rigorous testing.
  5. Mass Production: Upon approval, we move to high-volume manufacturing.
How do you address thermal management within the enclosure?
Thermal management is a core design focus. Our solutions often include:
  • Integrated cooling plates that allow for liquid cooling.
  • Optimized internal structures that promote even air flow for air-cooled systems.
  • The use of materials with high thermal conductivity to dissipate heat efficiently.
What certifications or standards do your enclosures comply with?
Our manufacturing processes and final products are designed to meet or exceed international automotive and safety standards.
This includes standards related to crash safety (e.g., ECE R100), IP ratings for ingress protection (e.g., IP67), and various quality management systems like IATF 16949.
Can your enclosures be used for Energy Storage Systems (ESS) as well as EVs?
Absolutely. While the core principles of safety and durability are the same, we adapt the design for ESS applications. This often involves scaling up the size, modifying the mounting points, and ensuring compatibility with stationary power storage requirements.
What are the key advantages of choosing Haiyan Metal for battery enclosures?
Our key advantages include:
  • Durability: Enclosures built for long-term performance under demanding conditions.
  • Lightweight Design: Maximizing vehicle range without compromising safety.
  • Precision Engineering: High-quality manufacturing for perfect fit and function.
  • End-to-End Service: Support from initial design to volume production.
