AI Technical Summary
Existing technologies cannot produce battery protection boards with high energy density, fast charging, and low temperature rise, especially in mobile phones and laptops. Conventional thick copper PCBs cannot meet the battery protection requirements of small space and high current.
The outer layer adopts a 6OZ thick copper battery protection board design, with the top and bottom layers of circuits made of 0.2mm thick T2 copper material. They are connected through through holes, and the gaps between the copper are filled with resin or glass fiber epoxy resin. Combined with a multi-layer lamination process, the surface of the outer circuit is covered with green and white oil layers to achieve high current carrying capacity and low temperature rise.
It improves high current carrying capacity by more than 30%, reduces temperature rise by more than 20°C, has a compact and reliable structure, is suitable for small space scenarios, improves electrical connection stability, and meets the layout requirements of small pin spacing of the fuel meter.
