CATL EnerOne Outdoor Liquid Cooling Battery Storage Cabinet
372.7 kWh outdoor liquid-cooled LFP BESS cabinet with 10,000-cycle cells
Overview
EnerOne is CATL's modular outdoor liquid-cooling LFP battery energy storage system, launched in 2020 and awarded the ees AWARD in 2022. Each unit has a nominal capacity of 372.7 kWh on a 1.69 square metre footprint and is compatible with inverters operating from 600 to 1500 V. It uses liquid-cooling cell-to-pack technology that keeps the temperature difference between cells within 3 degrees Celsius.
Key highlights
- 372.7 kWh nominal capacity on a 1.69 m2 outdoor footprint
- LFP cells with 280 Ah capacity, 1C discharge rate and up to 10,000 cycles
- Integrated frequency-conversion liquid cooling limits cell delta-T to 3 C
- Compatible with inverters operating from 600 V to 1500 V DC
- IP66 protection on main components with -30 C to +55 C ambient range
- Passed UL9540A with no fire and no thermal propagation without suppression
