AI Technical Summary
Existing UPS lithium battery packs experience rapid accumulation of localized hot spots during fast charging or pulse discharging, resulting in large temperature differences between individual cells, a high risk of thermal runaway, and an inability to dynamically adjust the heat dissipation structure, leading to a delayed temperature rise and affecting the safety and flexibility of the battery pack.
The hollow thermally conductive battery cell mounting shell is printed using a NiTi shape memory alloy skeleton and carbon nanotube-reinforced polyether ketone ketone composite material. The heat dissipation fins automatically unfold when the temperature reaches 50℃. Combined with a low-resistance centrifugal pump formed by a magnetically levitated brushless drive impeller and a baffle plate, liquid-gas coaxial heat exchange is achieved. The battery cell side pressure relief valve design and multi-channel exhaust system ensure the safe discharge of heat and pressure.
It achieves passive adaptive heat dissipation, reduces cell wall temperature, delays thermal runaway propagation time, improves the reliability and flexibility of battery pack use, and ensures that the controller unit maintains full-frequency operation under high load.
