When the cost barrier of liquid cooling technology is shattered, the evolution path of the energy storage and charging industries will be completely rewritten.
On March 27, 2026, at the "Full Ecosystem Synergy · Semi-Immersion Intelligent Cooling" East Group Digital Energy Full Ecosystem Strategy Launch held in the ancient capital of Xi'an, East Group not only announced its strategic leap from an "equipment provider" to a "digital energy full-ecosystem service provider," but also dropped a "depth charge" into the 2026 new energy infrastructure market with its industry-first "semi-immersion liquid cooling technology" and the "air-liquid parity" business strategy.
Strategic Upgrade: From Selling Equipment to Building a "Panoramic Energy Ecosystem"
At the outset of the conference, Liu Baohui, Vice President of East Group and General Manager of the PV-Storage-Charging Integrated Energy Business, set the tone: "Break down energy silos and create a zero-carbon closed loop." This marked East Group's accelerated departure from the label of a pure hardware supplier, pivoting towards building a three-dimensional ecosystem covering "energy storage - charging - power supply - computing power - energy management."
Luo Yi, General Manager of the Solution and Delivery Center at East Group Energy Storage Technology Co., Ltd., further elaborated on the implementation path of the "Panoramic Ecosystem Solution" — through a full-stack self-developed technology matrix, achieving full lifecycle energy management from the generation side to the user side, making the flow of energy "visible, manageable, and controllable."
This strategic transformation received recognition from local government and authoritative institutions. Yang Hua, Deputy Director of the Xi'an High-tech Zone Management Committee, emphasized in her speech that the technological innovation of leading enterprises like East Group is a vital engine for regional green and low-carbon development. Experts from TÜV SÜD and Gansu Electric Power Design Institute provided authoritative endorsements for the large-scale rollout of liquid cooling technology from standardization and safety perspectives.
Technological Breakthrough: The "One Stone, Two Birds" of Semi-Immersion Liquid Cooling
If strategy provides the direction, then products are the sharp blades thrust into the market.
The most significant highlight of this launch event was undoubtedly the industry-first semi-immersion liquid cooling technology unveiled by East Group's Chief Engineer Ma Chaoqun. This technology ingeniously balances the high efficiency of "full immersion" with the cost-effectiveness of "air cooling," and is simultaneously applied to both core scenarios — energy storage and ultra-fast charging — achieving "one technology, dual empowerment."
1. Storage Side: The 6.7MWh "Capacity Monster" Reducing Costs and Increasing Efficiency
The system adopts an 8-row, 16-cluster configuration, equipped with 314Ah cells, achieving a 6.7MWh large-capacity deployment that significantly increases energy density and effectively reduces floor space.
Its core advantage lies in semi-immersion precision temperature control: insulating coolant is precisely sprayed onto core heating components such as battery terminals, achieving extreme temperature uniformity with a cluster-level temperature difference ≤2°C. Compared to traditional air cooling, the heat dissipation efficiency is improved several times over, battery cycle life is extended by 20%, and the levelized cost of electricity over the full lifecycle is reduced by 10%.
More subversively, through engineering optimization and cost control, East Group has priced this high-performance liquid-cooled energy storage system exactly the same as traditional air-cooled systems, truly delivering "more for the same price," providing the optimal cost-effective solution for scenarios with high safety and reliability demands, such as shared energy storage and grid-side storage.
2. Charging Side: The 1072kW "Megawatt Flash Charge" Reconstructs the Replenishment Experience
Addressing the charging pain points of electric heavy-duty trucks and commercial vehicle trunk logistics, East Group launched the Qinchong 1072kW Megawatt Flash Charger, with a single cabinet power of 1.07MW and a total parallel power exceeding 4.2MW from four units, supporting a total current of 2400A. This enables electric heavy-duty trucks with 500-1000kWh batteries to replenish several hundred kilometers of range in 10-15 minutes, achieving the ultimate experience of "charging as fast as refueling."
This product also utilizes semi-immersion liquid cooling technology to precisely cool core components such as IGBT modules and charging gun cables, with a lifespan exceeding 10 years and a module failure rate of less than 0.1%. Coupled with IP65/C5 high protection and a ≤45dB low-noise design, it is suitable for complex scenarios like outdoor environments and industrial parks. Moreover, its cost is benchmarked against traditional air-cooled ultra-fast chargers, accelerating the large-scale deployment of megawatt-level ultra-fast charging networks through "air-liquid parity."
In addition to the two core new products, East Group simultaneously released second-generation rate-type sodium-ion battery cells, full-stack liquid-cooled data center core products, and the upgraded E-Cloud smart energy management platform, forming a full-stack technology matrix of "Energy Storage + Ultra-Fast Charging + Sodium Batteries + Computing Power + AI Management."
Market Disruption: "Air-Liquid Parity" Ignites an Industry Pricing Restructuring
"Enjoy the liquid cooling experience at the cost of air cooling." — This was East Group's most resounding commitment at the launch event. The "air-liquid parity" strategy directly targets the biggest pain point in liquid cooling adoption: excessively high initial investment.
Through large-scale manufacturing and design optimization, East Group has successfully driven the comprehensive cost of semi-immersion liquid cooling products down to a level comparable to traditional air-cooled products. This means that when building charging stations or energy storage power stations, operators no longer need to pay a hefty premium for liquid cooling solutions to obtain longer equipment lifespan, lower O&M costs, and superior safety performance.
This strategy is expected to spark a wave of technology substitution that penetrates from the high-end market into the mainstream market in 2026.
At a time when the new energy industry is shifting from "scale-based competition" to "value-based competition," the significance of East Group's launch event lies not only in the unveiling of several new products, but also in being the first to break the industry stereotype that "liquid cooling equals expensive."
When "air-liquid parity" becomes a reality, the cost-effectiveness ceiling for energy storage and charging infrastructure will be completely overturned.
For the industry, this is a revolution in efficiency and cost; for users, it heralds a safer, more affordable zero-carbon future.
