Software
NOTE:
Additional configuration is possible for GPIO pins configured as inputs. This additional
configuration allows for the input to trigger a fault when changing state. This configuration is
made on the
Fault Mask
tab.
Figure 20. Aux and I/O Tab
7.8
Balancing Tab
The
Balancing
tab, shown in
, allows selection of the cells which are balanced when the
Start
Balancing
button is clicked and polling is active. In the specific example, balancing for cells 3, 5, 12, 13,
and 14 is both enabled and turned on with polling active.
A small indicator appears to the right of the voltage/time grid, next to the appropriate cell, for each cell
selected on the
Balancing
tab. This virtual LED indicator is black when balancing is off, green when
balancing of a cell is on without faults and red if balancing is on and a fault has occurred.
NOTE:
The example screen capture was taken with a resistor ladder consisting of alternating
resistor values connected to the cell sense lines, so the effect is somewhat different from
what is expected when battery cells are connected to the sense lines.
