Battery Equalization
The BMM incorporates a Midpoint Voltage Sensor to allow monitoring of cell
imbalance.
• Voltage measured via the Midpoint Voltage Sensor on the battery is
monitored to ensure it remains within 0.5V of half the battery voltage.
• If the voltage moves outside this range a non-urgent Voltage Imbalance
alarm is triggered. The BMM then schedules an equalization charge to
commence following the current charge if connected, or following the
next completed charge.
• Should the midpoint voltage imbalance persist, further equalizations will
be scheduled. Repeated Voltage Imbalance alarms that will not clear
should be investigated as this indicates a potential battery problem.
Enabling Voltage Imbalance Monitoring
To enable voltage imbalance monitoring, ensure the BMM equipped battery
and charger are connected to a PC with Charger Interface software and
select the Voltage Imbalance Monitoring option under the Battery Module
Confi guration tab.
