On April 15, Beijing Jingneng International Integrated Smart Energy Company under Beijing Energy International, independently designed and developed liquid-cooled energy storage battery boxes and modules, completed the type test of the new national standard “Lithium-ion Batteries for Power Storage” (GB/T 36276-2023), and obtained the test outcome report. This marks the company as one of the first domestic enterprises to complete the certification of energy storage system products under the new national standard, fully demonstrating its capability in independent R&D of energy storage products and system integration. 

The energy storage business layout of Beijing Energy International focuses on “investment safety and production safety” as its core concept, utilizing the most advanced 314Ah battery cells. Through optimized modeling and design of the cooling system, precise control of cell temperature has been achieved, enhancing system efficiency and lifespan, thus providing security for project investment. Simultaneously, a pack-level fire-fighting system is employed, enabling precise warning and targeted fire-fighting, effectively ensuring the production safety of energy storage systems. 

Next, Beijing Energy International will continue to deepen its R&D in the field of energy storage systems and investment, independently developing energy storage digital systems, second-generation liquid-cooled systems, and sodium-ion energy storage systems, continuously exploring new technological directions, strengthening technological capabilities, and promoting the healthy and sustainable development of the company in the field of energy storage.
