Key Features

 

Patented Immersion Cooling

Battery cells are submerged in non-toxic
dielectric oil for direct active thermal
management, fire suppression, and
propagation prevention.

Thermal Management

Liquid immersion cooling offers
superior thermal management by
enhancing heat transfer efficiency
through direct contact with the
cooling liquid.

Integrated BMS & EMS

Our non-Chinese BMS and EMS ensure
optimal performance, safety, and
efficiency, offering unmatched
reliability and control.

Enhanced Durability

Our battery modules have an IP67
rating while our cabinet is rated at
IP54, ensuring reliable performance
in demanding environments.

1.OS may automatically derate power as necessary to maintain proper cell temperatures.
2.Test ambient temperature at 25 C.
3.The end-of-life (EOL) of a Battery Energy Storage System (BESS) is influenced by its age, usage
application, and environmental temperature, which may result in an actual lifespan of less than 20 years.
4.Assumes 1 cycle per day in fresh cell period, not includes aging situation.
5.DOD 80% is the recommended specification to delay aging.
