A Fault indicates the state of the battery system has been detected outside of its safe operational range. The cause of
the fault must be identified and a corrective action must be performed. For instance, if the fault is a cell voltage
measurement has become too low, the cell maintenance manual must be reviewed to identify what remedial actions are
required.
A Fault is more severe than a Warning and the source of the fault must be discovered and resolved before attempting
to clear and continue operating the battery system.
5.3.2. Pack Voltage
The pack voltage radial gauge shows the average stack voltage of the stacks connected to the
common DC bus.
If no stacks are connected, a value of 0 V is displayed.
5.3.3. Pack Current
The pack current radial gauge shows the battery pack current which is the addition of each stack
current that are connected to the common DC bus. The maximum charge current limit and the
maximum discharge current limit is also shown. The acceptable current range is visualized on the
gauge by the blue arc. An absence of the blue arc indicates the battery pack cannot be charged or
discharged in its present condition.
A negative current value indicates the battery pack is charging. A positive current value indicates the
battery pack is discharging.
If no stacks are connected, a value of 0 A is displayed.
