Construction of a Storage Station
A storage station was constructed and demonstrated utilizing three sub-storage systems with a capacity of 20kWh each. Each sub-storage system has a permanent power of 100kW with a 320 A charging and discharging current. The monitoring electronics measure the individual cell voltage with an accuracy of 1.2 mV. Through the redundant design, the storage system reaches a 24/7 operational availability, making it suitable for grid applications.
