The equipment includes branded computer, software system, precision voltage and internal resistance measuring instrument, code scanning mechanism, batch loading device, robot automatic grading, automatic unloading and other devices;

According to the AC internal resistance, open circuit voltage and other parameters of lithium batteries, the batteries are accurately classified and grouped according to various performance parameters;

The built-in high-precision internal resistance meter BT3562A can automatically collect AC internal resistance and open circuit voltage. The sorting process is automatically controlled;

The battery cell performance data tested by the system is managed in a database for long-term storage and strong traceability.
