Each system consists of a stainless steel rack with a master control unit and up to 6 CHL500 power stage modules of 500 A each. Systems are available from 500 A to 3000 A at 6 to 12 V. The modules are water cooled, and the master control unit connects to the QTS software via Ethernet.
In the test set-up editor, up to 5 test profiles can be combined in a sequence, for example AC impedance, then a constant current discharge, then a second AC impedance for comparison. Customer-specific characteristics and signal shapes such as rectangular pulses or sine waves are possible.
It evaluates internal resistance, impedance and the relaxation voltage after discharge. The methods include CCVmin, the two-tier DC load method for DC resistance (DCR), AC impedance at 1 kHz (ACR), deltaV and a second OCV after the load is removed. Each battery is rated ACCEPTED or FAILED.
All recorded data are provided at PLC level for pick-up by higher-level SCADA systems. The system also calculates the average value and standard deviation of the open circuit voltage and the high current voltage across all accepted batteries, which helps to evaluate the whole batch.
