Trumony 1P48S Liquid Cooled Aluminum Battery Bottom Enclosure for Electric Buses
As electric city buses move toward higher-capacity 1P48S battery packs, reliable thermal management and structural protection have become decisive factors for fleet safety and service life. Trumony has released a purpose-built 1P48S liquid cooled aluminum battery bottom enclosure, manufactured with aluminum extrusion and friction stir welding (FSW), to give commercial vehicle builders a ready-to-install, leak-free solution.
Product Overview
The enclosure is engineered specifically for 1P48S battery packs widely adopted in electric bus and commercial electric vehicle platforms. With overall dimensions of 1060 × 616 × 120 mm, it integrates liquid cooling channels directly beneath the battery modules. The welded aluminum structure delivers high mechanical strength, excellent air and water tightness, and long service life under continuous commercial operation. Both ready stock and custom battery enclosure solutions are available.
Key Features
- Friction Stir Welding + Extrusion Process: The material does not melt during welding, resulting in low deformation and excellent sealing performance that eliminates leakage risk in the liquid cooling loop.
- Built-in Liquid Cooling Channel: Integrated liquid cooling provides uniform temperature control for 1P48S modules, improving battery cycle life and system safety.
- Optimized for Electric Bus: Structurally reinforced to withstand the vibration and shock of commercial buses, with stable performance under harsh road conditions.
- High Precision Machining: Precision-drilled mounting holes and interface ports for MSD, heat and communication connections enable easy assembly with battery modules and top cover.
- Trumony One-stop Solution: We manufacture battery enclosures, liquid cooling plates and thermal management components for both EV and ESS applications.
