Battery Monitoring System for Lead-acid Batteries BMS
Operation of the monitoring system BMS is suitable for applications, which require monitoring of no-failure operation of batteries. Utilization of the battery monitoring system will offer the user information about an upcoming battery failure, prevent back-up system failures caused by poor battery condition and prevent destruction of an entire battery set due to failure of one cell.
BMS monitoring system monitors and signals in the real time states of accumulator batteries, for example deep battery discharge, eventually discharging of single cells / blocks of the battery set, cells / blocks voltage unbalance, excessive discharging or charging currents of the battery set, battery temperature variation from the stated value and other parameters. Overrun of every mentioned parameter can destroy of the battery set, so it is needed to have immediate information about battery status.
Battery monitoring system is fully autonomy working. Error entries as well informative one are stored in the internal memory of the control system what enables to the user also additionally analyse the conditions during the use of batteries.
The whole system consists of the control unit (MP) and the appropriate number of measurement modules (MM) of the same structural design, current probes (CP), temperature sensors (MT) and related number of connecting condanalyzuctors and conductors of voltage sensors.
The system can be powered directly from the battery. Therefore, it is not necessary to provide the power supply from back-up distribution mains, what enable to situate the battery-monitoring system directly into accumulators´ installation or storage room. Another option is to power the system by an external source.

Features of the battery monitoring system
Detects imminent battery failures
Typical battery problems like sulfation, corrosion, gassing, dry-out, thermal runaway are detectable given proper monitoring. Changes in voltage and temperature trend indicate onset of such issues
Prevents thermal runaways
By means of an embedded dry contact output, the BMS system is capable of tripping the battery breaker in the event of a thermal runaway. Automatic stringwise battery disconnection is possible, given the presence of a relay, through tripping the battery breaker when user defined parameters are met
Identifies upcoming required battery replacement
By monitoring voltage trends, BMS allows the user to detect weak or damaged batteries in early stages of deterioration. Timely replacement of bad batteries is vital to improving the lifespan of the battery system as a whole.
Simpler maintenance
BMS improves the service quality by providing remote monitoring through Internet, VPN, or any network, that allows for the downloading of real time data and battery history. It is now possible to test batteries without going through the trouble of disconnecting them from the system. Maintenance and testing take place under real operating conditions and require no downtime!
