on April 1, chuneng new energy demonstrated its energy storage full-scene solution at the ESIE2026 energy storage exhibition, taking the lead in demonstrating the 6.25MWh energy storage system solution based on the integration of 588Ah battery and CTP3.0 module-free technology, which attracted great attention from the industry. As the industry’s first solution to deeply integrate 588Ah large core and CTP3.0 modeless technology, it shows unique value in the dimensions of system integration efficiency, thermal management safety and large-scale application.

200GWh capacity “Re-Note” 588Ah: extreme balance achieves leading performance
under the background that the industry generally focuses on improving battery capacity, chuneng’s new generation 588Ah energy storage battery has further strengthened the product dimensions of “long cycle, high safety and high reliability” while maintaining the leading product performance, reflecting its deep understanding of the application essence of energy storage products.

in terms of performance parameters, under the lithium iron phosphate system, the 588Ah battery has achieved mass energy density of 190Wh/kg and volume energy density of 419Wh, the performance of energy efficiency 96.5% leads the way. Through the application of the three core technologies of multi-stage particle size control of the positive electrode, stable skeleton design of the negative electrode and self-healing technology of the electrolyte, the 588Ah battery has achieved a cycle life of more than 12000 times and a high capacity retention rate.
in terms of safety, chuneng aimed at the actual pain points of large-scale energy storage application scenarios in the product design stage, from battery intrinsic safety to system-level protection. through the dual power of structural innovation and material innovation, chuneng built a full stack safety system for 588Ah batteries, laying a solid foundation for the long-term stable operation of the energy storage system.
In terms of reliability, the 588Ah battery has translated the mature material system and manufacturing process of Chuneng’s mass-produced batteries. Its core reliability has passed batch verification. At the same time, relying on the mature supply chain and large-scale production system, it can bring “predictable and reliable” stable quality to customers.
it is worth noting that under the background of the increasingly prominent demand for large-scale and high-quality production capacity in the industry, chuaneng has laid out a capacity plan of more than 200GWh for 588ah batteries , which will provide a solid guarantee for large-scale mass production of 588ah batteries.
CTP3.0 efficiency breaks through 60JPH, enabling large-scale safe application of 6.25MWh system
588Ah battery has laid a solid foundation on the performance side, while CTP3.0 modular-free integration technology is a key part of its safe and efficient application to 6.25MWh system. Chuneng highlighted its innovative application in the field of efficient integration of energy storage systems through the combination scheme of “588Ah battery + CTP3.0 platform + CORNEX M6 energy storage system.

Based on 588Ah battery and CTP3.0 platform, Chuneng further introduced a new generation CORNEX M6 energy storage system solution, A set of progressive and collaborative optimization technology matrix is constructed. The system adopts standard 666.66cm prefabricated cabin design, system rated power of 6250kWh, with top-out wind and heat management system and active equalization BMS, to achieve overall improvement of safety and stability at the system level.
Among them, the industry’s first CTP3.0 modular integration technology is an important breakthrough in the traditional energy storage PACK structure. According to on-site technicians, this integration technology breaks the shackles of module homogeneity. by streamlining the redundant structure, the volume energy density of a single package is as high as 280Wh/L, and the rated power reaches 195.68kWh, thus realizing the ultimate integration of batteries and battery packs in a limited space.
more importantly, the CTP3.0 platform adopts the “absorption and protection double method” process to integrate 104 588Ah batteries into the box . the production process is greatly optimized, which not only improves the intrinsic safety, but also pushes the production efficiency (60JPH) to four times the industry average efficiency (15JPH) . This leap-forward improvement means that Chuneng will have significant cost advantages and delivery efficiency in large-scale manufacturing.
conclusion
from the performance breakthrough of 588Ah battery, to the efficiency innovation of CTP3.0 module-free technology, to the efficient integrated landing of 6.25MWh energy storage system, chuneng has built a full-link innovation matrix from battery to system. The core logic of this matrix is clear and clear: based on the high-capacity battery, with the modular structure as the engine, and finally at the system level to achieve both safety and efficiency . In the industry to continue to deepen the application value of the key nodes , Chuneng is to full link innovation, running out of their own “acceleration”.
