Our Success Stories

Real results are the most powerful proof of our expertise.

100+ MWh Utility-Scale BESS Project

Challenge: A client's 280Ah cell container system required a battery cluster temperature difference of <3°C and had to pass stringent thermal runaway tests.

Solution: We provided an integrated liquid cooling system with FSW cold plates and high-precision manifold assemblies.

Result: System temperature difference was stabilized within 2.5°C, auxiliary power consumption was reduced by 15%, and it successfully passed GB/UL safety certifications.

C&I Liquid-Cooled BESS Cabinet

Challenge: A client needed to develop a cost-effective, highly integrated 215kWh liquid-cooled BESS cabinet with strict cost and space constraints.

Solution: We designed an innovative integrated liquid cooling module, pre-assembling the cold plate, pipelines, and connectors to simplify the client's assembly process.

Result: The client's assembly time was cut by 50%, system cost was reduced by 10%, and the product was quickly and successfully launched.

High-Altitude Solar+Storage Project

Challenge: A BESS deployed at 4,000 meters faced cooling challenges from large diurnal temperature variations and low air pressure.

Solution: We provided a liquid cooling system with a reinforced structure and special anti-corrosion treatment, and optimized the control strategy for the high-altitude environment.

Result: The system has operated without failure for over 3 years, with a battery degradation rate better than expected, becoming an industry benchmark.

Developing String Inverter Heat Sinks for a Global Top 3 Client

Challenge: The client's new 200kW+ inverter needed a 30% power increase in the same volume, while meeting C5 corrosion resistance.

Solution: We optimized the fin design through simulation and used a high-conductivity die-cast aluminum alloy with a special surface treatment.

Result:Thermal performance increased by 25%, weight was reduced by 10%, successfully helping the client capture the high-power string market.

Enabling Central Inverters for Floating PV Plants

Challenge: The high-humidity, high-salt-spray environment of floating PV projects posed an extreme reliability challenge for inverter cooling systems.

Solution: We provided an IP68-rated forced air cooling module with heat pipes and a fully sealed design.

Result:The product passed a 1500-hour enhanced salt spray test and has been operating without failure in multiple floating PV projects for over 5 years.

A Cost-Effective Solution for Residential Hybrid Inverters

Challenge: A client's residential hybrid inverter required a heat sink that was aesthetic, silent, and extremely cost-competitive.

Solution: We designed an extrusion heat sink with an artistic fin structure and significantly reduced costs through process optimization.

Result:While meeting all performance requirements, we reduced the client's cooling cost by 20%, leading to an order of several million units.

Four Core Thermal Management Challenges in BESS

The safety and lifespan of batteries are central to the value of an energy storage system, and it all begins with superior thermal management.

Extreme Safety Against Thermal Runaway

Preventing the occurrence of thermal runaway in a single cell and suppressing its propagation in extreme cases is the primary and greatest challenge of BESS thermal management.

Cell Temperature Consistency & Lifespan

Excessive temperature differences within a battery cluster lead to inconsistent cell degradation, severely impacting the system's cycle life and State of Health (SOH).

High Efficiency & Low Auxiliary Power

The energy consumption of the thermal system itself (fans, pumps, etc.) directly impacts the Round-Trip Efficiency (RTE) and must be minimized while ensuring effectiveness.
