(XD Thermal: Suzhou, China) -- XD Thermal Technology, a thermal management manufacturer, has advanced its side-cooling solutions for cylindrical cell-to-pack battery packs. Large-scale production capacity and automotive-grade process control are positioning the company as a key supplier.

In super-fast-charging cylindrical packs, the challenge is heat accumulation during high current/voltage in charging and discharging with high C-rate. XD Thermal’s side liquid-cooling concept routes serpentine tubes along the cell sidewall, increasing effective contact area vs. bottom cooling plates. The enlarged vertical contact surface well resolved the challenge of heat gradients in Z-axial direction because individual cells stay in a balanced temperature range, a positive factor to maintain a longer life for Li-ion batteries.
