I would not recommend equating one cell and one battery because
some of the Type47 parameters are designed to limit voltage and
current per cell. A cell in a lead acid battery is about 2.1V. If
you are considering a system that uses 12V batteries then there are
about 6 cells in series per battery. Assuming that these are 12V (6
cells in series) batteries then to have 11 batteries in series would
mean that you've got 66 cells in series and 2 cells in parallel.<br>
kind regards,<br>

<p>Hello TRNSYS users, </p>
<p><br>
</p>
<p>I want to model a battery bank( 22 batteries, 11 series, 2
parallel). </p>
<p>known properties about a battery 100Ah. </p>
<p><br>
</p>
<p><br>
</p>
<p> I want to model this using 47b, I am wondering about
following properties of 47b.
</p>
<p><br>
</p>
<p><br>
</p>
<p>INPUT PARAMETERS</p>
<p>1. Cell Energy Capacity Ah ( would that be ok to plugin
100Ah here which is total capacity of a battery )
</p>
<p>2. Cells in parallel ( would that be ok to plugin 2 which
depicts two rows of batteries)
</p>
<p>3. Cells in Series ( would that be ok to plugin 11 which
batteries in one row)
</p>
<p><br>
</p>
<p>It is clearly understood that these properties are for each
cell of a single battery. If I have to have enter the cell
properties for a single battery. How I can model a battery
bank?
</p>
<p><br>
</p>
<p>OUTPUT PARAMETERS</p>
<p><br>
</p>
<p>1. State of charge: The State Of Charge is expressed in the
same units as the rated cell capacity (Ah). This value is
given for one cell (all cells are assumed to be identical).
</p>
<p>Question: this values goes up to 400Ah, I wondering about
this because Plugged in cell energy capacity is only
100Ah.[input1]</p>
<p><br>
</p>
<p>Any help will be greatly appreciated! </p>
<p><br>
</p>
<p>Thanks, </p>
