What defines CATL’s rack battery innovation?
CATL unveiled third-generation cell-to-pack (CTP) technology with 450Wh/kg energy density, integrating liquid-cooled modules into standardized 19-inch racks. Their carbon-neutral production line reduced pack assembly costs by 18% through laser welding optimization.
Beyond energy density, CATL’s 48V/72V rack systems feature silicon-carbon anode chemistry enabling 15-minute 80% fast charging. Pro Tip: Their modular design allows 10kWh-1MWh scalability via parallel connections, ideal for data centers. For example, a 72V 300Ah CATL rack battery delivers 21.6kWh with ≤2% monthly self-discharge, outperforming traditional NMC systems. Thermal runaway prevention uses dual-phase change materials melting at 60°C and 85°C.
How did EVE Energy advance rack battery tech?
EVE Energy debuted all-polar cylindrical cells with 280Wh/kg density in 19-inch racks, using graphene-coated aluminum shells for 40% better thermal conductivity than steel cases.
Practically speaking, their 5C continuous discharge capability supports high-power UPS applications. Real-world testing showed 20,000 cycles at 80% DoD when maintained at 25±3°C. Pro Tip: EVE’s smart racks integrate wireless SOC sensors, eliminating voltage measurement drift. For instance, their 48V 200Ah server battery maintains ±1% accuracy across -20°C to 55°C ranges.
