Description
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 recorded 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)

Data recording (USB logging)
At the end of the configuration of all test modes there is the option to enable the USB logging feature. With a USB
stick plugged and formatted as required (see
1.9.6.5
), 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
Regardless the setting for the recording interval, the values “Ah” and “Wh” are only calculated
by the device once per second. When using an interval setting of < 1 s, several identical values
of Ah and Wh are written into the log file.

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
