CRRC Zhuzhou Institute Unveils 6.X Liquid-Cooled Energy Storage System

The CRRC Zhuzhou Institute has exciting news for the energy sector as it prepares to debut its groundbreaking 6.X Liquid-Cooled Energy Storage System at the highly anticipated Smarter E Europe 2026. This event is scheduled to take place from June 23 to 25 at Messe München in Munich, Germany, specifically at Booths B2.540 and B2.640 in Hall B2. Supported by the successful implementation of its 200 MWh Bohot BESS project in Bulgaria, which achieved full grid connection in April 2026, the new system promises several crucial advancements to enhance energy storage technology.

Key Features of the 6.X Liquid-Cooled Energy Storage System

1. Enhanced Energy Density: The 6.X system boasts a remarkable 25% increase in energy density, which allows it to store more energy in a smaller physical footprint, reducing site footprint by over 20%. This feature is particularly beneficial for addressing land use constraints and easing planning approval challenges in various European markets.

2. Optimized Thermal Management: With a state-of-the-art heat-dissipation design, the 6.X system utilizes temperature-adaptive control, leading to more than a 10% reduction in thermal-management energy consumption. This enhancement significantly boosts overall system efficiency, making it a more sustainable energy solution.

3. Versatile Application Scope: This comprehensive energy storage solution is designed to cater to utility generation, grid-side applications, and commercial and industrial needs. Its versatile nature allows asset owners to maximize returns across diverse operational scenarios, making it an appealing choice for various stakeholders in the energy sector.

4. Safety Validated at Scale: Safety remains a top priority for CRRC Zhuzhou Institute, which has published extensive safety results from large-scale fire tests and a thorough six-tier extreme-safety validation in compliance with internationally recognized standards such as UL 9540A and NFPA 855.

The Bohot Project: A Successful Case Study

The Bohot BESS project, which reached full-grid connection in April 2026, serves as a demonstration of CRRC's commitment to quality and compliance. This project not only meets Europe’s stringent interconnection requirements but also showcases the practicality of the new 6.X system. Using a modular architecture comprised of DC battery cabins, integrated AC cabins, and PCS units paired with a 33 kV grid-interconnection system, the project is currently operating successfully. It has already garnered recognition from local partners and regulators, laying a solid foundation for CRRC's deeper involvement in the European market.

Community Engagement and Environmental Considerations

CRRC Zhuzhou Institute is dedicated to building sustainable supply chains and prioritizes the hiring of local personnel, providing skills training, and emphasizing local procurement throughout all stages of project development. The organization places a premium on ecological protection measures and thorough environmental impact assessments that encompass energy efficiency, carbon reduction, and biodiversity protection, fostering trust with both governments and regulators worldwide.

Additional Innovations: The 'Chixiao' 460 kW PV Inverter

In addition to the 6.X Liquid-Cooled Energy Storage System, CRRC Zhuzhou Institute will also showcase its 'Chixiao' 460 kW PV inverter. This cutting-edge inverter is designed to inherit high-speed rail-grade standards and boasts a rated power of 460 kW (with peak performance reaching 506 kW). Compared to previous models, it achieves a notable 28% improvement in power density, utilizing next-generation silicon-carbide (SiC) devices to effectively lower system costs for large-scale ground-mounted power plants.
