Against the backdrop of accelerating global energy structure transformation, energy storage technology, as a critical link supporting the large-scale application of renewable energy, is becoming increasingly important. East Group, ranked among the Global Top 500 New Energy Enterprises and recognized as a National Manufacturing Single Champion Enterprise, leverages over 30 years of deep expertise in power electronics and energy efficiency management to accelerate its presence in the energy storage sector, committed to delivering efficient, safe, and intelligent solutions.
Full-Stack Self-Development Builds Technological Advantage
Unlike the common hardware integration approach within the industry, the core competitiveness of East Group's energy storage business lies in its full-stack self-development capabilities. The company independently develops and manufactures the complete suite of core equipment for energy storage systems, including Power Conversion Systems (PCS), Battery Management Systems (BMS), Energy Management Systems (EMS), Power Management Systems (PMS), and battery packs (PACK). This deeply vertically integrated model enables system-level "4S" integration, effectively enhancing system integration, safety, and operational efficiency.
On the technology front, East Group has launched a full range of 1500V string-type and centralized energy storage systems, employing advanced cooling technologies such as liquid cooling and spray cooling. These technologies not only improve cooling efficiency by approximately 30% but also reduce the levelized cost of electricity (LCOE) by 15% over the full system lifecycle. Its 160kW-3500kW energy storage PCS adopts modular and grid-forming design, achieving a conversion efficiency of up to 99%, and can operate stably in harsh environments ranging from -35°C to 60°C, demonstrating advantages in conversion efficiency and response speed.
Notably, East Group actively integrates AI technology for battery life prediction, thermal runaway early warning, and economic operation strategy optimization. Its intelligent liquid cooling temperature control technology can keep cell temperature differences within 3°C, while self-developed automatic recharge systems and ActiveLi battery control systems enable intelligent management of cells and battery clusters. These technologies significantly enhance the safety, energy efficiency, and multi-scenario adaptability of energy storage systems, covering a wide range of applications including renewable energy paired storage, standalone/shared storage, and grid-side peak shaving and frequency regulation.
Diversified Product Portfolio Covering Full-Scenario Demands
To meet the diverse needs of grid-side, generation-side, and user-side applications, East Group has built a rich product portfolio encompassing multiple technology routes, including string-type, centralized, air-cooled, liquid-cooled, and the industry-leading immersion-cooled solutions.
For large-scale generation-side and grid-side projects, East Group continues to iterate and upgrade its liquid-cooled and air-cooled 1500V string-type and centralized energy storage systems, with single-unit capacities ranging from 5MWh to 26.8MWh, and was among the first to launch an ultra-safe immersion-cooled energy storage system solution. In the user-side commercial and industrial sector, its 1000V fully liquid-cooled 135kW/261kWh C&I integrated energy storage system leads the industry with its ultra-high power density.
East Group also offers customized solutions. Its C&I energy storage solution adopts the "ONE BRAND STATION" design philosophy, integrating batteries, 3S systems, and fire suppression systems, emphasizing safety, reliability, intelligence, efficiency, and economic flexibility, while featuring multiple protective characteristics such as "anti-corrosion, fireproof, waterproof, dustproof, and shockproof" to adapt to complex operating conditions. In the PV-storage-charging integration field, its "Super Mix PV-Storage-Charging Cloud Integrated Solution" has been successfully implemented in projects such as the Sinopec PV-Storage-Charging Integrated Charging Demonstration Station.
Furthermore, East Group's "AI + Energy Management Solution" deeply integrates cloud management platforms, station-side management products, and edge execution devices, introduces large model technology to empower intelligence, focusing on large-scale storage, C&I energy storage, and PV-storage-charging scenarios, supporting centralized monitoring, power ancillary trading, and deep data mining, driving the upgrade transition from "energy production" to "smart energy management."
Market Recognition and Large-Scale Delivery Capability
In terms of market performance, East Group's energy storage business has experienced significant growth, with its global installed energy storage capacity reportedly exceeding 8GWh. The company has deeply participated in national grid-side projects and provides services to major energy groups such as China Huadian, CTG New Energy, CNNC Huineng, State Power Investment Corporation, and China Southern Power Grid, while also offering one-stop solutions in generation-side support and C&I energy storage markets. Representative projects include the Xinjiang Huadian Tianshan North Base New Energy Project Supporting Storage (300MW/1200MWh), Zhejiang Sanmei Chemical C&I Energy Storage Power Station, and Zhuhai Public Transport C&I Energy Storage Project, all achieving favorable economic and social benefits.
East Group's comprehensive strength in the energy storage field has also received recognition from authoritative institutions. It has been included in the Bloomberg NEF (BNEF) Tier 1 Energy Storage Manufacturers list and has been honored with multiple industry awards, including "2024 Top 10 Chinese Enterprises in Energy Storage System Shipments" and "2023-2024 Top 10 Influential C&I Energy Storage Products in China." These accolades fully demonstrate East Group's leading position in energy storage technology innovation, market performance, and industry influence.
Global Footprint Ensures Efficient Delivery and Reliable Service
To support the rapidly growing market demand, East Group has established manufacturing bases with gigawatt-level (GW) annual production capacity in Guangdong, Henan, Xinjiang, Gansu, and other locations, with an annual delivery capacity exceeding 10GWh. These production bases utilize MES systems, integrated automated production lines, and intelligent robotics equipment to achieve fully digitalized and intelligent management across the entire chain from raw materials to finished products, ensuring high-quality product delivery.
Simultaneously, East Group has built a global after-sales service network. With 268 customer centers worldwide and a marketing and service network spanning over 100 countries and regions, the company provides 7×24 rapid response, delivering timely and efficient technical support and service assurance to its customers.
Future Outlook: Innovation-Driven Continued Leadership
Looking ahead, East Group will continue to increase its R&D investment in the energy storage sector, persistently driven by innovation, closely following market and customer demands to promote product iteration and upgrades. The company will continuously introduce more innovative PV-storage-charging products and services, promoting the industry's upgrade transition from "energy production" to "smart energy management," contributing greater strength to the global energy transition and green sustainable development.
