Netherlands-based AEG Power Solutions has announced the launch of a wireless battery management system for large energy storage applications.
The system, called MoniStore, is designed for use in storage systems featuring lead-acid or Ni-Cd batteries. Wireless communication allows for safe electrical isolation and monitoring of large battery systems with more than 300 single cells connected in series, AEG said.
Inside the system, a sensor connected to each battery’s negative pole continuously monitors the functionality of individual cells by measuring their voltage and temperature. Wireless sensors transmit this data to an evaluation unit, which interfaces with an energy management system.
The evaluation unit can change the system’s power consumption, enabling passive cell balancing. AEG says other features include reduced need for cabling, with need only for measuring clamps; ease of installation and maintenance– a sensor exchange can be accomplished during full operation– and low power demand, as each cell provides the power supply for its sensor.
Continuous monitoring during operation can ensure availability, good utilisation and a long lifecycle for battery storage systems in typical on- and off-grid applications, AEG said.
“MoniStore is an innovation that will support smooth operation of battery energy storage systems which are developing strongly,” said Dr Peter Wallmeier, CTO at AEG Power Solutions.
The product will be launched under AEG’s Grid Friendly label, which is applied to its products that contribute to grid stabilisation or grid integration of alternative energy sources.
