AI Technical Summary
Cable ties are prone to fatigue and corrosion in battery devices, leading to breakage and affecting the structural stability and reliability of the battery device.
The cable ties are designed in the form of a cable tie body and a redundant component. The redundant component is connected to the cable tie body to provide additional constraint to replace a broken cable tie body and improve the stability of the battery pack.
After the cable tie breaks, the redundant components can effectively secure the battery pack, reduce safety hazards, and improve the reliability and stability of the battery device.
