High-Efficiency Liquid-Cooled PACK

Reinforced aluminum alloy base plate with hot-dip galvanization and protective spray coating for exterior housing.

Optimized liquid cooling channel design maximizes surface area for enhanced thermal performance.

Modular architecture enables simpler maintenance and meets electrical spacing requirements.

Robust laser welding forms reliable connections between terminals and busbars.
Insulating sheets inserted between cells to elevate insulation rating.

Precise monitoring of individual cell voltages and temperatures.

Integrated safety features including alarm system, pressure relief valve, and independent fire suppression nozzle.

Aluminum liquid cooling plate

The aluminum alloy liquid cooling plates use advanced fluxless high temperature extrusion welding technology, leaving no flux residues in the coolant channels, minimizing the risk of conductive cooling fluid and preventing corrosion of the liquid cooling modules to ensure electrical grid safety.
 
CFD simulation technology

CFD simulation technology is utilized to perform thermal analysis and simulate the heat dissipation of the energy storage battery pack, rationally matching the power of the liquid cooling unit to maintain a constant working temperature.
