The E.ON Energy Research Center at RWTH Aachen University, energy utility E.ON SE, battery manufacturer Exide Technologies GmbH’s GNB® Industrial Power division, battery manufacturer beta-motion GmbH, and inverter manufacturer SMA Solar Technology AG will build this year in Aachen a worldwide unique large-scale modular battery storage system with a power range of five megawatts. The project named “Modular Multi-Megawatt Multi-Technology Medium-Voltage Battery Storage” or M5BAT will receive €6.5 million in funding from Germany’s Federal Ministry for Economic Affairs and Energy.
What makes M5BAT distinctive is its modularity, which enables it to optimally combine a variety of battery technologies. It uses
- high-output lithium ion batteries for short-duration discharge,
- high-temperature batteries for medium-duration discharge, and
- lead-acid batteries for short- and medium-duration discharge.
