Clean energy and ESS solutions provider Envision Energy has launched a advanced 5 MWh containerized liquid-cooled battery energy storage system (BESS). The system not only enhances Envision's energy storage product lineup but also sets new benchmarks for safety and performance in the industry, the company claims. 

Available for global markets, the new product utilizes 315 Ah LFP cells renowned for their high energy density and extended lifespan. It is compliant to international safety standards such as UL 9540A, UL 1973, IEC 62 933, and NFPA 855, according to the manufacturer. 

"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. "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", he added. 

Envision claims that its latest ESS adopts a "prevention-first" safety ethos featuring multi-layered safety mechanisms. Each unit integrates a sophisticated six-tier electrical safety system, including an advanced off-gas detection system to identify the onset of any thermal incidents early. 

Further, the system also includes a pack-level coolant based thermal runaway management system designed to quickly extinguish potential fires and is supplemented by a water sprinkler system when necessary. 

Aerogel pads between cells are employed to 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, Envision adds. 

Lastly, the 5 MWh Container ESS is designed for high-capacity energy storage, maximizing space efficiency within a compact 20-foot container, significantly reducing balance of plant (BOP) costs compared to other designs, the company notes.
