Battery monitoring module -BMM

Battery monitoring module -BMM


Product application:

The real-time on-line monitoring and balanced maintenance of the backup battery pack for the noil UPS/HVDC power supply.

The real-time on-line monitoring and balanced maintenance of the spare battery group in the data center of the noil IDC data center.

The real-time on-line monitoring and balanced maintenance of the dc current power supply backup battery group of delta power, rail transit and railway.


The automatic monitoring monomer battery voltage/internal resistance/temperature, group terminal voltage/current, each module can monitor 20, 24, 27, 32 and 54 (bmm-b type).

The real-time alarm function of delta is implemented to realize the over-limit alarm of voltage, internal resistance, temperature and SOC. Support dry node output alarm.

The two - line automatic monitoring monomer battery voltage can be automatically identified according to the battery pack status. Real-time monitoring and display of support line resistance/connection strip pressure drop.

The internal resistance of the four - line automatic monitoring monomer batteries can be set up in the collection cycle. The classification of resistance data in different conditions is preserved.

Delta LCD display (192 x 48 dot matrix) data storage function with RS485/ RS232, USB, CAN and other interfaces.

Deltax embedded in battery performance intelligent analysis model to realize real-time diagnosis of SOC and SOH.

The automatic or manual control of the battery for the maintenance and activation of the battery can delay the failure of the battery.
