AEG Power Solutions, a provider of electronics systems and solutions for industrial power supplies and renewable energy solutions, has launched an innovative wireless battery cell control system, MoniStore-SC.BCCS designed for battery energy storage applications.
MoniStore-SC.BCCS will support smooth operation of battery energy storage systems, says Peter Wallmeier, AEG Power Solutions CTO.
Innovative MW battery storage systems are being used for grid support and grid building in typical on- and off-grid applications. They are designed to deliver unlimited availability, good utilization and long lifecycle of the connected battery.
AEG Power Solutions has developed the new wireless battery cell control system to enable smooth operation of battery energy storage systems. The battery sensor is simply connected to the batteries negative pole. It continuously monitors the functionality of the individual battery cells by measuring cell voltage and temperature.
The wireless sensors transmit all relevant parameters via the Zigbee protocol to a receiver module which transfers the data to an evaluation unit. Here it completes the information with other parameters derived from the data received (e.g. SOC and SOH) for the energy management system.
Thanks to the new system, wireless communication allows for safe electrical isolation, and monitoring of large battery systems with more than 300 single cells, connected in series.
The system does not require complex cabling as it only needs the measuring clamps and no additional cables. Installation is extremely simple and even a sensor exchange can be done during full operation.

Since each cell provides the power supply for its sensor, it demands extremely low power input.
Current / power consumption can systematically be influenced or increased by the evaluation unit thus enabling a passive cell balancing. The system also offers high reliability and long service life.
The sensors will mainly be used in large battery energy storage systems. The new system is designed for global use with lead acid or Ni-Cd batteries.
