The group standard “Technical Specification for Immersion Liquid Cooling System of Lithium-ion Batteries for Energy Storage” (Standard No.: T/CAEE016-2025), administered by the China Electronic Equipment Technology Development Association, has been fully implemented since January 1, 2026. As one of the core drafting units, Hongying New Energy participated in the compilation of this standard together with more than 30 leading industry institutions, including China Southern Power Grid, the Guangzhou Institute of Energy Conversion of the Chinese Academy of Sciences, and the University of Shanghai for Science and Technology, driving the industry toward a new stage of high-quality development with innovative technology and practical applications.
Filling an Industry Gap and Setting a Technical Benchmark
As a key technical path for improving the energy efficiency and safety of energy storage systems, immersion liquid cooling technology has long lacked unified and standardized technical standards.
The group standard co-formulated by Hongying New Energy fills the technical gap in this field. The standard comprehensively clarifies the technical specifications and test methods for immersion liquid cooling systems, covering physical performance, chemical performance, thermal management systems, system design, safety, and environmental friendliness. It provides industry enterprises with a full-process basis for the application of immersion liquid cooling technology and will strongly promote the unification of product quality standards and the healthy and orderly development of the industry.
Leading Technological Development and Forging Standards Through Practice
As a one-stop integrated energy service provider, Hongying New Energy has rich experience in product R&D and project application in the field of immersion energy storage, contributing key practical wisdom to the formulation of the group standard.
In 2025, the company launched its ePower series immersion energy storage products, innovatively adopting third-generation immersion liquid cooling technology to achieve superior temperature uniformity and faster heat conduction rates. System efficiency exceeds 89%, and overall service life is extended by about 20%, fully demonstrating its energy storage technological strength.
In terms of safety verification, Hongying New Energy upholds a rigorous and pragmatic attitude and commissioned authoritative testing institutions to conduct strict tests in accordance with the national standard “Lithium-ion Batteries for Electric Energy Storage” (GB/T 36276-2023). The professional test report results show that Hongying New Energy’s immersion liquid cooling technology can effectively block thermal propagation under extreme conditions, achieving “zero fire and zero explosion,” setting a safety benchmark for the industry with its excellent safety performance.
