Method 2 – during running – faster but time-consuming
You can also instruct the BACS web manager to take control step by step.
If you choose running this way, euqalizing is configured to pause each day for a specific time window. The advantage is that your UPS
system is not on its own for the first few weeks. BACS has an eye on it and equalizing is most of the week enabled.
This method allows to plan special charge/discharge cycles without BACS equalizing provides and speed up the forming process. As an
example, if your batteries have a discharge/charge cicle of about 6 hours, you can plan a “not-equalized time window of 6 hours” dayly,
weekly – you can customize this time window to fit to your conditions.
In this example, the job Pause Equalizing will stop the equalizing
process from 6:00pm Uhr to 11:00pm.
This will provide a unique time window to run a custom discharge /
charge cycle and log the voltage behavior of the batteries. This
method could be very interesting if you change some batteries
and mix some new with old batteries. Equalizing will save your
existing, already formed batteries and your new batteries have the
chance to form up with all other batteries.
In this example, we will use a periodic message reporting - if you know that equalizing pauses from 6:00 pm to 11:00 pm, you could
create a "formation report" and get the according log files by mail:
In this case, set the je-mail job timing to Weekly and instruct the
BACS WEBMANAGER to generate a status mail with the
current battery data at 23:15 on Mondays, Wednesdays and
Fridays.
As a consequence of a scheduled hour-by-hour formation of batteries, the entire formation process will take some more time:
Technically, the internal battery chemistry is calmed by eliminating the necessary voltage fluctuations associated with equalization - this
will slow down the forming process.
On the other hand, evaluating of data is easier because you can directly compare how the batteries behave. This will allow you to
determine very precisely when there will be no improvement in the voltage values and fully activate the equalization with pinpoint
accuracy. As a side effect, you may train to spot strange measuring data.
Method 3 – Completly scheduled with unique single jobs
If you choose to climb this way, you need some experiences about using batteries and their behavior when equalize them. In general,
the sense of scheduled tasks is to plan jobs and execute them automatically when the time has come to trigger a function. You may
choose between cyclic jobs like sending mails with log files or single jobs like a small text message to your RCCMD client to remember
yourself a single event is pending.
However, the advantage of this method is, that you can design and configure a general road map to form the batteries. As an example,
it may look like this job list:
- Enable Equalizing for 2 days
- Send an email with log files for data evaluation
- Pause Equalizing for 7 days
- Send an email for data evaluation
- Enable Equalisation for 3 days
- Pause Equalizing for 5 days
- Send a mail with log files for data evaluation
- Pause Equalizing the next 7 days for some hours
- Send a mail with log files for data evaluation
- […]
This will allow you to create a normalized 6-month battery forming procedure. To abort this scheduled task list because the forming
process is finished earlier than expected, just delet this job list.
Note:
Forming new battery systems is an individual matter that largly bases on experience. In general, you can say:
Unformed high-quality batteries reach the final operating state faster than unformed less-quality batteries. But it is alsow possible that
pre-formed low-quality batteries may surprise you very much.
Please keep in mind, each battery system is a unique installation that needs an individual point of view.
