Product Details

The Battery Rear Base is a critical load-bearing aluminum structural component located at the rear section of an EV battery pack or module frame. It provides rigid support for battery modules and ensures dimensional stability under vibration and impact. Manufactured from high-grade extruded aluminum (6000 series, T6 temper), this rear base offers high strength-to-weight ratio and excellent corrosion resistance.

Our battery rear base is designed for seamless integration with the overall battery tray or enclosure system. It features pre-machined mounting holes and precisely controlled tolerances, enabling fast assembly on production lines. Whether for passenger electric vehicles, commercial trucks, or retrofit applications, this part can be customized in dimensions, hole patterns, and surface treatment to meet your exact requirements.

Battery Rear Base FAQ

Q: What exactly is a Battery Rear Base?

A: It’s the aluminum structural plate that supports the rear portion of an EV battery module or pack, providing secure mounting points and helping maintain the integrity of the entire enclosure under dynamic loads.

Q: Can you produce a rear base according to my drawings?

A: Absolutely. We accept 2D/3D drawings in common formats. Our engineering team will review manufacturability and suggest optimizations if needed before prototyping.

Q: What is the typical lead time for a custom Battery Rear Base order?

A: Prototype samples can be ready in as fast as 2–3 weeks, depending on complexity. Mass production lead times vary from 4–8 weeks, discussed case by case.

Q: Do you have a minimum order quantity (MOQ)?

A: We are flexible. For initial trials, we can produce smaller quantities. MOQ will depend on the specific extrusion die and finishing requirements; we’ll confirm it after design review.

Q: Is the aluminum alloy recyclable and environmentally compliant?

A: Yes. The 6000-series aluminum we use is fully recyclable without loss of properties, supporting your sustainability targets and compliance with environmental regulations.
