Batterie EV

EV batteries operate under fast charging, high-rate discharge, and frequent thermal cycling. Heat from cells, modules, busbars, and BMS electronics can create temperature imbalance, accelerate aging, reduce usable capacity, and increase safety risk.

Sheen thermal interface materials and functional materials (gap fillers, thermal pads/gels, and potting/adhesives) build stable, low-resistance heat paths to cold plates, pack frames, or housings to: ① improve cell-to-cell temperature uniformity and extend cycle life; ② reduce hotspots during fast charge and peak power output; ③ enhance safety margin by controlling temperature rise; ④ maintain reliable contact under vibration and thermal cycling; and ⑤ accelerate design-in with custom thickness, die-cut parts, and engineering support from prototype to mass production.
