Battery Mid-point Monitoring Description
Battery Mid-point Monitoring provides a cost-effective method for the early detection of
internal battery faults. The voltages of the two halves of a battery string are measured and the
system controller generates an alarm signal if a voltage imbalance is detected.
A voltage imbalance is an indication that one or more cells has an internal fault. Further
investigation can then isolate the faulty cell(s) and action can be taken to correct the problem
and prevent a total battery failure.
