PKNERGY has launched a new all-in-one liquid-cooled BESS (Battery Energy Storage System) series. The upgraded solution features globally leading long-life CATL LFP cells, offering a lifespan of up to 8000 cycles at 70% DOD (Depth of Discharge). Compared to traditional containerized battery cooling systems, energy consumption is reduced by 30%, and the lifespan is extended by 2 years, making it a more promising solution for return on investment. This energy storage solution utilizes a flexible modular design, with the ability to parallel up to 10 battery units, easily meeting any capacity requirement, large or small.
CATL is the world’s largest supplier of lithium batteries by shipment volume and a partner to many renowned companies. In deep collaboration with CATL, PKNERGY has launched an all-in-one energy storage system designed for commercial and industrial applications, utilizing CATL’s lithium iron phosphate (LFP) cells. These cells are known for their long lifespan and high safety performance, making them one of the top battery types in the energy storage market.
The advanced liquid cooling system ensures a cell temperature difference of less than 3%, effectively preventing system overheating and enhancing energy efficiency. This optimized cooling system allows for stable performance and improved longevity of the battery energy storage system.
The comprehensive cloud platform enables 24/7 online monitoring for users, providing automatic SOC (State of Charge) calibration, intelligent liquid cooling temperature control, and real-time system fault alerts. This eliminates the need for on-site maintenance, reducing labor costs and improving operational efficiency.
The system features three-level short circuit protection and a compartmentalized design that separates the battery chamber from the electrical chamber, preventing the spread of thermal runaway and ensuring PACK-level safety. The enclosure is fire-resistant for up to 2 hours and equipped with top explosion vents, effectively safeguarding both the system and personnel.
The PKNERGY liquid-cooled energy storage system solution can be equipped with a self-developed battery pack balancer, increasing the system’s usable capacity by 10%. This further unlocks the potential of the liquid-cooled BESS, maximizing its performance and efficiency.
