Global energy storage manufacturer Envision Energy has announced the launch of its 5 MWh Containerised Liquid-Cooled Battery Energy Storage System (ESS). The company claims this system sets new benchmarks for battery energy storage system safety and performance with a “prevention-first” approach that features multi-layered safety mechanisms.

Each 5 MHh Container ESS unit integrates a six-tier electrical safety system, including an off-gas detection system to identify the onset of any thermal incidents early. The system also includes a pack-level coolant-based thermal runaway management system designed to quickly extinguish potential fires, and it is supplemented by a water sprinkler system when necessary. Aerogel pads between cells inhibit heat propagation, while active ventilation, deflagration panels, and an AI IoT-based intelligent fire monitoring and predictive fault system proactively addresses potential safety concerns. The 5 MWh Container ESS has secured UL 9540A, UL 1973, and IEC 62 933 certifications, and it complies to NFPA 855.

The 5 MWh Container ESS is designed for high-density storage and maximizes space efficiency within a compact 20-foot container, significantly reducing balance of plant (BOP) costs compared to other designs, Envision claims. The system uses 315 Ah LFP cells, celebrated for their high energy density and extended lifespan. The seamless integration of Envision Energy’s Power Conversion System (PCS) and Energy Management System (EMS)/SCADA system addresses compatibility issues, according to the company.

“The introduction of the 5 MWh Container ESS marks a major advancement in our energy storage portfolio,” said Kane Xu, global VP of Envision Energy, in a press release. “This product underscores our commitment to delivering advanced, safe, and economically viable energy solutions that support our global clients in their transition to sustainable energy.”

Envision’s 5 MWh Container ESS is now available worldwide.
