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.

Adjustable Aluminum Glass Louver Window With Removable Screen Glass Louver Window Shutters

Glass aluminum blinds are a modern and functional window design that combines the advantages of glass and aluminum to provide excellent durability and aesthetics. The following is a detailed product introduction to glass aluminum shutters: Design and material: Glass aluminum blinds use high-quality aluminum alloy frames combined with strong and durable glass panels. Aluminum alloy is lightweight and corrosion-resistant, while glass provides clear vision and good light transmission. Louver function: The blind design built into the window is not only beautiful, but can also effectively control the light entering the room. Users can easily adjust the angle of the louvers to achieve light blocking, privacy protection or ventilation purposes. Thermal and Sound Insulation: This type of window is designed with thermal and sound insulation in mind. The use of double-glazed glass and sealing strips can effectively reduce external noise and reduce heat transfer, thereby saving energy while keeping the building warm in winter and cool in summer. Security performance: Glass-aluminum blinds are usually equipped with tempered glass and a multi-point locking system, which greatly improves the security of the window. Remains stable and safe even in adverse weather conditions. Easy to maintain: Aluminum is easy to clean and does not rust or fade easily. The louver structure is also designed to facilitate cleaning and maintenance, ensuring that the windows remain beautiful over the long term. Diverse applications: Glass aluminum shutters are suitable for a variety of architectural styles and interior decorations, whether they are modern and simple or traditional and classic, they can be perfectly integrated with them. Customization options: Users can choose different colors, sizes and styles according to their needs to meet personalized decoration requirements. Glass aluminum blinds are a common choice in modern homes and commercial buildings due to their elegant appearance, excellent functionality and good durability.
