ADVANCED FEATURES

SELF-CALIBRATION CAPABILITY

Each channel in the system can self-calibrate the voltage measurement mechanism by utilizing a precision voltage reference in the device. This allows for automated voltage calibration on command without user intervention. Current calibration is done using a traditional calibration kit and requires user invervention to perform.

BUILT-IN OSCILLOSCOPE

Each channel has the capability of capturing quick snapshots of the output current and voltage to provide deep diagnostic capabilities of the battery cell. This snap-shot is fully programmable and can be triggered automatically during the test run.

BUILT-IN DCIR

Each channel has the capability to perform a DCI R function automatically and provide the calculated results. This saves in the complexity of trying to program it in the automation system.

BUILT-IN EIS

Each channel in the system can also perform Electrochemical Impedance Spectroscopy (EIS) to give detailed data on the state of health of the cell. Because the system can perform this on every channel automatically during test runs, this powerful process can be used without adding any additional testing hardware.

BUILT-IN CYBER-SECURITY

The system is capable of meeting strict cyber-security requirements which disables all the external data ports on the device to protect the boot sector from malicious attacks. This is accomplished with a manual key switch on the front of the device.

BUILT-IN CELL EMULATION

Once the battery cells have been characterized utilizing the testing functions of the battery tester, the system can also be used as a battery cell emulator. In particular, the 128 channel 20mA device could be used to simulate the battery cells to a BMS system to test the BMS functionality including cell balancing (up to 20mA).
