Recently, Envision Energy's "AC-DC Integrated" 5.0/5.6MWh energy storage system series officially rolled off the production line at its Jiangyin factory. The "AC-DC Integrated" series includes two models, 5MWh and 5.6MWh, both housed in standard 20-foot containers, with the 5.6MWh model being the world's largest capacity "AC-DC Integrated" energy storage system. With the roll-out of the 5.0/5.6MWh energy storage systems, Envision Energy's "AC-DC Integrated" series products are now officially capable of mass delivery.
The Envision "AC-DC Integrated" 5.6MWh energy storage system is equipped with Envision Power's 350Ah energy storage-specific cells, offering a cycle life of 15,000 cycles, 3 years of zero degradation, and a round-trip efficiency (RTE) of 96%. Compared to the industry-standard 314/315Ah cells, this system increases energy density to 435Wh/L, while the 20-foot container capacity has been boosted to 5.6MWh.
Unlike the industry's mainstream AC-DC split design solutions, the Envision "AC-DC Integrated" 5.6MWh energy storage system uses an integrated AC-DC design, featuring one cluster management system that eliminates inter-cluster circulation, improving lifetime discharge by over 8%. Its dual liquid cooling system is highly integrated, supporting shoulder-to-shoulder and back-to-back installations, reducing the occupied area by 50%. The "AC-DC Integrated" structure also ensures that the DC cables remain inside the cabinet. With pre-installation and pre-commissioning at the factory, installation and debugging time are greatly reduced. According to estimates, the Envision "AC-DC Integrated" 5.6MWh energy storage system reduces the cost per kilowatt-hour by approximately 45% compared to mainstream products on the market.
Based on the mature 315Ah energy storage-specific cell production line, the Envision "AC-DC Integrated" 5MWh energy storage system also began mass production on the same day, offering high lifetime discharge, easy installation and maintenance, and low kilowatt-hour costs. This further enriches Envision Energy's product lineup and provides customers with more choices.
Envision Energy possesses full-stack technological capabilities, ranging from battery cells, PCS, EMS, BMS to SCADA systems, all of which are self-researched and manufactured. However, Envision Energy does not position itself solely as an equipment provider but as a total solutions provider, starting with the end goal of meeting the needs of new energy systems to define and optimize solutions. Based on insights into the new energy system, Envision Energy has also developed energy storage solutions for trading-type and grid-constructing-type systems, seamlessly integrated with its own equipment.
For grid-constructing-type energy storage, the system is equipped with Envision's next-generation system-level grid-constructing technology—GenGrid generative grid technology. It features "1+4" full-stack grid construction, adaptable to all scenarios and operating conditions, and meets all market standards, supporting a 100% renewable energy power system.
