The EZGO RXV Eco battery tray is a structural component designed to securely house and protect lithium-ion battery packs in golf carts and low-speed electric vehicles (LSEVs). Made from high-strength aluminum alloys, it provides impact resistance, thermal management support, and vibration dampening while reducing weight by 20-30% compared to steel alternatives. Integrated mounting points ensure compatibility with EZGO RXV chassis, and its sealed design meets IP67 standards against water/dust ingress.

What materials optimize EZGO RXV battery trays?
The tray uses 6000-series aluminum alloys (like 6061-T6) for optimal strength-to-weight ratios. These alloys provide 240-310 MPa yield strength while being 65% lighter than steel. Anodized coatings add corrosion resistance for outdoor operation in varied climates.
Aluminum’s thermal conductivity (130-150 W/m·K) helps dissipate heat from battery cells during fast charging. Pro Tip: Check for ISO 16750-3 certification to verify vibration resistance up to 30G impacts. For example, a 12mm-thick 6061 tray can withstand 1,500 N·m torsion loads—equivalent to surviving potholes at 25 mph.
How does tray geometry affect battery performance?
Precision-stamped ribbed patterns increase stiffness by 40% without added weight. The RXV Eco’s tray features 8-12mm deep ribs spaced 50mm apart, creating crash zones that absorb 15-20% of collision energy before reaching battery cells.
Mounting flange heights (typically 25-30mm) prevent road debris strikes, while CNC-machined coolant channels maintain ±2°C temperature uniformity across battery modules. Why does this matter? Cells operating within ideal 20-40°C ranges deliver 18% more cycle life than those in uneven thermal environments.
| Design Feature | Steel Tray | EZGO Aluminum Tray |
|---|---|---|
| Weight (100Ah capacity) | 28-32 kg | 19-22 kg |
| Corrosion Resistance | 500h salt spray | 1,000h+ |
What safety standards govern battery trays?
EZGO trays comply with UN R100.02 for EV component safety, requiring:
- 15-minute fire containment
- 500V dielectric withstand
- 30-minute water immersion survival
Crush tests simulate 3x vehicle weight (1,500 kg for golf carts) without cell deformation. The honeycomb-style internal bracing deflects forces around cells—think of it as a “crumple zone” redirecting collision energy away from critical components.
How are trays installed/maintained?
Installation requires torque-controlled fastening (22-25 N·m for M10 bolts) to prevent galvanic corrosion. Silicone-based sealants between tray and chassis block moisture ingress—reapply every 5 years or 2,000 operating hours.
Inspect monthly for:
- Dents exceeding 3mm depth
- Loose mounting brackets (＞0.5mm play)
- Coating cracks near weld points
Pro Tip: Use non-conductive nylon brushes for cleaning to prevent accidental short circuits through exposed busbars.
| Maintenance Task | Frequency | Tool Required |
|---|---|---|
| Bolt torque check | Annual | Digital torque wrench |
| Seal integrity test | Biannual | Air pressure gauge |

FAQs
Only with matching 2018+ chassis—legacy models lack the required M10 threaded inserts. Retrofit kits include adapters but add 1.8-2.3kg weight.
How does tray weight affect golf cart range?
Every 5kg reduction extends range by 0.8-1.2km. The Eco tray’s 22kg mass enables 5-7% more distance versus steel equivalents.
