AI Technical Summary

Technical Problem

In existing technologies, when measuring the capacity of a single battery cell, the time required to adjust the internal temperature of the cell to the target temperature is too long, which affects the charging/discharging efficiency.

Method used

Thermoelectric elements are placed on the outer surface of the fixture to heat or cool the battery cells through the thermoelectric effect to quickly regulate their internal temperature. Combined with a cooler and a temperature control unit, the temperature is precisely controlled.

Benefits of technology

It significantly reduces the time required for the internal temperature of a battery cell to reach the target temperature, improving charging/discharging efficiency and the accuracy of capacity measurement.
