How to use „Pause Equalization”
As you can see, only Chuck Norris has an automatic battery forming process because his roundhouse kick will teach the batteries what
they want to do... In all other cases it is technically not possible because the batteries can vary enormously depending on batch, grade,
manufacturer, chemical composition, storage time after production, storage location, etc. It can actually happen that two batteries from
the same manufacturer need completely different time windows until they reach the formed state - New BACS-controlled UPS systems
must be observed individually.
Pause Equalization is thus a kind of "pause function" to facilitate the structured formation or reformation of batteries. To use this
function, open the scheduler and select the job Pause Equalizing:
Setting up Hours and job timing
How many hours you want to pause equalizing is difficult to answer - BACS can facilitate and accompany the formation process in many
ways. Here are 3 examples how to configure the BACS function pause equalizing:
Method 1: As easy as possible
Pause Equalizing for 5 days and repeat the job:
In this case, choose 120 hours and advice the CS141 to repeat once in a week:
The BACS Webmanager will pause equalizing for 120 hours or 5 days. The UPS is this given the chance to advance the battery
formation 5 days a week. Then the BACS Webmanager will enable Equalizing for 2 days and generate comparable data. After an
overall period of 7 days, the job will be re-run … The BACS Web Manager Monitoring will always inform you if something with the
batteries is not working as expected, even if Equalizing is temporarily disabled or pausing.
Use a second job to get status information about the forming process:
On initial start, the BACS Webmanagers integrated monitoring
system starts collecting all required battery data for a detailed
forming status evaluation. Just add a scheduled mail and the
BACS Webmanager will send your regular status reports including
necessary log files. You do not need dayly reports, getting a status
mail once a month should be enough to decide if the forming
process is finished. If there an additional problem occurs:
BACS will inform you immediately....
During data evaluation, what are you looking for?
As an example, if you start with 40 unformed batteries, you will
notice that each battery will show individual charge/discharge
voltages. This is not an issue, it is natural for both, pre-formed and
unformed batteries. With each discharge / charge cycle, the
voltage curves of all batteries approach each other until they are
only about 1V apart. If this can bee seen, batteries are in sync and the forming process is largely completed. You may quit and delete
the scheduled job "Pause Equalizing" and BACS begins its work.
With this method, you can evaluate the battery data once a month and are informed about the current state of health of the batteries. As
soon as the battery data reaches formation parameters and indicates that the formation has been completed successfully, the Pause
Euqalizing job can be adjusted or removed accordingly.
