8.4.5 Battery capacity test
Battery current output option is necessary for this option.
In order to check the battery performance, a battery test can be activated. The battery test discharges the battery
until a predefined voltage. It discharges the battery with a constant current. To achieve this, the charger output
voltage is slowly decreased until the battery discharge current reaches the desired level. Both charger and battery
will deliver current. This ensures you do not loose system performance in case a battery is in a bad condition or
has an open cell.
The battery test can only be performed on a 100% charged battery and should discharge the battery up to 60%.
The Battery test can be activated by the operator/serial command or can be initiated periodically.
If initiated periodically but the conditions to start the battery test is not met (see below), the battery test will be
postponed 24 hours and a new try is given. After three retries the test will be terminated until the next periodic cycle.
During the three retries the periodic counter is stopped and started again after the battery test is initiated.
If the battery test is manually initiated and periodic battery test is active as well, the periodic timer is reset upon
selecting manual battery test to prevent sequential battery tests.
The time needed to reach the End Voltage level is compared to the time of the previous battery test. This previous
time is multiplied with a tolerance factor to compensate for battery performance. If the time is shorter than this
reference time, an alarm "BATT.TEST FAILED" is generated. If the time is longer than the predefined time, or
within the defined percentage, a text "BATT.TEST PASSED" is generated. This is not an alarm situation but only
a message. It will disappear from the screen as soon as another function is selected from the front panel. In both
cases this event is written to the history list. If the time is longer than the predefined time, this new time is updated
and will be used as the reference for the next battery test.
