AI Technical Summary

⚠Technical Problem

Existing lithium battery clamping devices suffer from insufficient compatibility, low adjustment efficiency, and an inability to monitor changes in battery surface pressure and temperature in real time, resulting in low accuracy of experimental data and high equipment costs.

⚗Method used

A multi-dimensional signal testing device for lithium batteries was designed, integrating force, voltage, and temperature sensors. It adopts an adjustable outer frame and movable clamping plate structure to adapt to batteries of different sizes. The adjustment is simplified by using fine threaded adjustable bolts and a guide rail sliding structure, enabling simultaneous monitoring of multiple parameters.

🎯Benefits of technology

It improved the compatibility of the experimental setup and the reliability of the measurement results, reduced equipment costs, and increased experimental efficiency and data accuracy.
