AI Technical Summary
Existing lithium battery test probes or copper sheet clamps have low precision, making it difficult to ensure that the tabs are not scratched or stretched, and poor compatibility with different batteries, resulting in excessive contact resistance and affecting the current and voltage transmission effect.
A high-current probe with two copper sheets and two wires is used. The current probe and voltage probe are flexibly extended and retracted by springs to ensure full contact with the battery tabs. The synchronous and stable transmission of current and voltage is achieved through insulating sheets.
It achieves synchronous and stable transmission of current and voltage, improves testing efficiency, reduces costs, and enhances compatibility with different batteries.
