AI Technical Summary

Technical Problem

Existing battery management systems suffer from insufficient physical protection when installing control boards, making them susceptible to short circuits caused by mechanical impacts and contact with foreign metal objects, as well as circuit corrosion due to environmental erosion.

Method used

The upper and lower shells feature an asymmetrical design, with the control board secured by bolts. ABS+PC alloy material ensures insulation, reinforcing ribs enhance rigidity, and asymmetrical column holes and screw holes ensure a unique and correct mounting configuration to prevent misassembly.

Benefits of technology

This achieves a stable, suspended state for the control board, preventing vibration, shock, and short circuits, providing effective physical protection and insulation, and avoiding circuit corrosion.
