The test is completed when the measured battery voltage stays below the defined
voltage limit. This means the battery is almost empty and the available capacity
can be estimated by multiplying the consumed charge by compensation factor. For
example, if the defined target voltage means the battery to be 90% discharged,
a multiplication factor 1.11 can be used to estimate the available total capacity.
The device can compensate the cabling-loss voltage and include its internal charge
consumption to the total capacity.
Usually, the disconnectors are internally blocked during the battery test and the test
should be remotely stopped (information object [BATTERY_TEST_CONTROL_SC])
before the disconnectors can be operated. The blocked state can be
indicated by configuring the local/remote status to double-point indication
[DISCONNECTOR_LOCREM_xx].
The load limiter functionality and the heater are disabled during the test.
4.4.7.1 Settings
The battery capacity test settings are defined in the section [BATTERY_TEST].
4.4.7.2 Remote control of the battery test function
Once the battery test functionality is enabled on the configuration file, it can be
remotely controlled by protocol communication. The information object is defined
in the section [BATTERY_TEST_CONTROL_SC].
• 0 = Abort the battery test
• 1 = Start the battery test
4.4.7.3 Battery test status
The status of the battery testing is available for the protocol communication.
The information object is defined in the configuration file section
[BATTERY_TEST_STATUS_DPI].
• 0 = Idle (not testing the battery)
• 1 = Testing (discharging the battery by using external load)
• 2 = Test complete
• 3 = Test aborted
4.4.7.4 Battery capacity
The measured battery capacity can be reported as a short floating-point value.
The reporting unit is ampere-hours Ah. For settings, see the general floating-
point input settings. The measured capacity is always reported after the test
is completed. The information object is defined in the configuration file section
[BATTERY_TEST_CHARGE_FPI].
4.4.7.5 Measurement file
The device can generate the internal measurement file from the battery capacity
testing. The measurement file is written every
contains a time stamp, status, battery voltage, discharge current and the charge
