Description
Discharge capacity
Charge capacity
Test capacity
0...99999.99 Ah
Threshold for the max. capacity to consume from or feed to the battery
and after which the test can stop automatically. This is optional, so that
also more battery capacity can be consumed or supplied.
Action: Time limit
None, Signal, End of
test
Enables the optional stop condition
Discharge time
Charge time
Test time
0...10 h
Test time after which the test can stop automatically. This stop criteria is
optional, it means that single tests can also run longer than 10 h.
USB logging
on/off
By setting the check mark, USB logging is enabled and will record data on
a properly formatted USB stick, if plugged in to the front USB port. The re-
corded data differs from the USB log data recorded during “normal” USB
logging in all other operation modes of the device.
Logging interval
100 ms - 1 s, 5 s, 10 s
Writing interval for USB logging
3.11.16.6 Displayed values
During the test run, the display will show various values and statuses:
•
Actual battery voltage on the DC terminal
•
Discharge end voltage U
DV
in V (only in discharge mode)
•
Charge voltage in V (only in charge mode)
•
Actual discharge or charge current
•
Actual power
•
Total battery capacity (charging & discharging)
•
Total battery energy (charging & discharging)
•
Elapsed time
•
Regulation mode (CC, CP, CR, CV)

3.11.16.7 Data recording to USB stick
At the end of the configuration of all test modes there is the option to enable a logging feature. With a USB stick plugged
and formatted as required (see
), the device can record data during the test run directly to the stick and in the defined
interval. Active USB logging is indicated in the display with a small diskette symbol. After the test has stopped, the recorded
data will be available as text file in CSV format.
Log file format example from static discharge mode:
Static = Selected test mode
Iset = Discharging current
Pset = Max. power
Rset = Desired resistance
DV = Discharge end voltage
DT = Discharge end time
DC = Discharge end capacity
U/I/Pactual = Actual values
Ah = Consumed battery capacity
Wh = Consumed energy
Time = Elapsed test time
3.11.16.8 Possible reasons for battery test stop
The battery test function run can be stopped by different reasons:
•
Manual stop on the HMI with button “Stop”
•
After the max. test time has been reached and action
End of test
was set for it
•
After the max. battery capacity to consume has been reached and action
End of test
was set for it
•
Any device alarm which would also switch off the DC input, like OT
•
Reaching the threshold U
DV
(discharge end voltage)
•
Reaching the threshold for charging end current
