AI Technical Summary
In the existing technology, the circuit breaker of lithium-ion battery is prone to warping due to the top seal bulging during use, which causes poor contact. The existing treatment methods cannot effectively solve this problem.
A cell top sealing flattening mechanism is adopted, which uses clamping components and heating devices to hot-press the flared protrusion at the top seal of the cell, reducing its size, thereby reducing the stress on the circuit breaker and reducing the risk of the circuit breaker tilting.
It effectively reduces the risk of circuit breaker tilting, improves the contact reliability of the circuit breaker, and avoids the problem of poor contact.
