AI Technical Summary

Technical Problem

Existing electric bicycle batteries have problems such as failing compression tests, short circuits caused by heat conduction between the cells and the protection board, low structural reliability, low production efficiency, and safety concerns when used underwater.

Method used

The battery pack features a front and rear cover structure with bottom shell grooves and positioning interlocking on the inner side. The bracket and limiting struts work together, and the nickel sheet and PC board are in contact. Combined with screws, glue grooves and glue injection methods, the battery structure strength and reliability are enhanced. The battery pack's protection is improved through the integrated BMS board design and waterproof measures.

Benefits of technology

It improves the battery's resistance to compression and drops, enhances the reliability and water resistance of the battery pack, and improves production efficiency and product safety.
