The Aluminum battery bottom enclosure is one of the most important structural and thermal components in an energy storage system. As the bottom enclosure (battery tray), it carries the battery modules, provides mechanical support, and integrates liquid cooling to keep cells within a uniform temperature window. It directly influences temperature uniformity, cooling efficiency, sealing reliability, and overall battery lifespan.
This battery bottom enclosure is precision-engineered for 1P52S energy storage battery packs. Made of 3003mod aluminum alloy with vacuum brazing, it integrates structural support and liquid cooling in a single tray, delivering stable operating temperatures for long-term, reliable ESS operation.
