Envision Energy has unveiled its latest grid-scale battery energy storage system (BESS) at the recently held Electrical Energy Storage Alliance (EESA) Energy Storage Exhibition held in Shanghai. The product boasts an energy density of 541 kWh/㎡ in its class, significantly higher than many of BESS products available in global markets right now. 

The new BESS product, made up of 700 Ah lithium-iron phosphate (LFP) battery cells sourced from Japanese battery company AESC, packs a little over 8 MWh of energy storage capacity in a 20-foot container. With a roundtrip efficiency of 96 percent, the battery system claims a lifespan of about 16,000 charge-discharge cycles.

As per media reports, the battery system weighs about 55 tons. The system is liquid-cooled, and has a voltage range of 1500-2000 Volts. It is configurable to offer a storage backup of two to eight hours, depending on the customer's requirements. 

The company is expected to commercially launch the new 8 MWh BESS in global markets in the coming months, adding to its already robust BESS product lineup, while setting new benchmarks for safety and performance in the industry.

It is to be noted that Envision ventured into the 20-foot container-class of battery systems for grid-scale deployments last year. 

Recently in June this year, the company launched its 5 MWh containerized liquid-cooled BESS adhering to the highest safety standards and performance levels. It employs  315 Ah LFP battery cells, also sourced from AESC.
