Energy Density Increased by 25%, Footprint Reduced by 20%
Munich and Bohot, BulgariaJune 8, 2026 /PRNewswire/ — From June 23 to 25, 2026, CRRC Zhuzhou Institute will debut its new-generation 6.X liquid-cooled energy storage system at The Smarter E Europe 2026 in Munich, Germany, highlighting technological upgrades and experience in delivering benchmark energy storage projects in Europe. The booth is located at Hall B2, Booths B2.540 and B2.640. As of May 2026, CRRC Zhuzhou Institute’s energy storage business has covered 25 countries and regions worldwide.
New Product Debut: 6.X Liquid-Cooled Energy Storage System Enhances System Efficiency
Addressing pain points in European energy storage deployment, such as space constraints, energy efficiency bottlenecks, and high operational costs, CRRC Zhuzhou Institute has launched the new-generation 6.X liquid-cooled energy storage system. Visitors to the CRRC booth in Hall B2 can learn about the following key technological upgrades:
Improved Space Utilization: Compared to the previous generation, energy density is increased by 25%, and the overall station footprint is reduced by over 20%, effectively addressing challenges of land scarcity and stringent planning approvals in Europe.
Optimized Energy Efficiency: A dual-technology approach combining “top-exit heat dissipation design” and “temperature-adaptive control strategy” reduces auxiliary power consumption of the temperature control system by over 10%.
Full-Scenario Application Coverage: This integrated solution is fully adapted for power generation side, grid side, and commercial & industrial (C&I) scenarios, helping owners improve return on investment.
Benchmark Project: Bohot 200MWh Large-Scale Energy Storage Project in Bulgaria Meets Stringent European Grid Connection Standards
On April 3, 2026, the project, equipped with core equipment from CRRC Zhuzhou Institute, achieved full-capacity grid connection, meeting Europe’s rigorous grid connection technical requirements. Compliant delivery capability has become a key competitive advantage for the company in expanding the European market.
System Architecture Highlights: The project adopts a highly modular architecture, consisting of DC battery compartments, AC integrated compartments, and PCS, equipped with a 33kV grid interconnection system.
Safety Performance Verification: CRRC Zhuzhou Institute’s energy storage system has passed large-scale fire tests (based on UL 9540A:2026 and NFPA 855:2026 standards), as well as multi-level extreme safety test results covering cell, PACK, and compartment levels.

Localized Operations: Building a Green Future with the European Market
In expanding overseas markets, CRRC Zhuzhou Institute adheres to a localized operations strategy, promoting the development of local green industry chains through local recruitment, skills training, and local supply chain procurement. Additionally, the company strictly implements full lifecycle ecological protection measures and environmental impact assessments, which are key foundations for winning trust from governments and institutions in multiple countries.
Co-Exhibition: “Chixiao” 460kW PV Inverter – Power Increased by 28%, First Use of SiC Devices
Furthermore, CRRC Zhuzhou Institute’s “Chixiao” 460kW PV inverter will also be showcased at the exhibition. This product inherits high-speed rail-grade design standards, with a rated power increased to 460kW (maximum 506kW), a power density improvement of 28%, and the first adoption of next-generation SiC devices, effectively reducing system costs for large-scale ground-mounted power plants.
We cordially invite you to visit our booth to explore new opportunities in the European clean energy market.
