Industry Context: Scaling Challenges in High-Capacity ESS
As energy storage systems (ESS) evolve toward higher capacity and tighter integration, thermal management becomes a decisive factor in system safety, performance stability, and lifecycle economics. The 104S ESS cooling plate is purpose-built to address the heat dissipation demands of 314Ah high-voltage battery packs, aligning with the 104-series (~400V) architecture widely adopted in containerized ESS. This standardization facilitates seamless grid integration while ensuring thermal uniformity across increasingly dense battery configurations.
Structural Design: Precision-Engineered for Uniform Cooling
Manufactured from high-conductivity aluminum alloy (200–220 W/m·K), the cooling plate adopts an advanced extruded channel design with precision-machined internal flow paths (5–8 mm diameter). This architecture enables consistent coolant distribution, effectively eliminating localized hotspots. With optimized dimensions (length: 2180–2200 mm, width: 740–810 mm, height: 10–41 mm), the plate fully covers 104-series modules, maintaining a temperature differential below 2°C under 0.5C charge–discharge conditions. The one-piece extrusion combined with argon arc welding ensures structural integrity and minimizes leakage risks, which is critical for long-term outdoor deployment.
Reliability & Adaptability: Designed for Harsh Operating Conditions
To meet diverse application requirements, the cooling plate supports multiple surface treatments, including anodization and sandblasting, enhancing insulation performance, corrosion resistance, and electromagnetic compatibility (EMC). Its flange-type interface ensures secure and stable connections under high-pressure liquid cooling conditions. With a load-bearing capacity of up to 970 kg and validated 700-hour salt spray resistance, the design demonstrates strong environmental durability across utility-scale and commercial ESS installations.
Thermal Performance: Maximizing Efficiency and Battery Lifespan
By optimizing coolant flow rates within the 8–12 L/min range, the system achieves a heat transfer efficiency of up to 98.2%, effectively maintaining cell temperatures below 35°C. This precise thermal control mitigates degradation mechanisms, extends battery service life, and supports higher cycle stability. In parallel, the lightweight and compact structure reduces system-level mechanical complexity, contributing to overall cost efficiency.
Application Value: Supporting the Global Energy Transition
The 104S cooling plate integrates seamlessly into grid-scale renewable energy storage systems, including solar and wind ESS, as well as commercial containerized and mobile energy solutions. As the global energy landscape accelerates toward decarbonization, high-performance thermal management solutions such as the 104S cooling plate play a foundational role in enabling safe, efficient, and scalable energy storage infrastructure.
