Characterization of vanadium redox - flow batteries
Vanadium redox-flow batteries are one of the promising battery technologies. A 15kW/120kWh vanadium battery was installed as part of the SYSLAB facility at Risø DTU. The battery was installed in August 2008, and cell stacks were changed twice, first time immediately after the installation. The overall efficiency was measured at around 60% inclusive
Results
Vanadium redox-flow batteries are one of the promising battery technologies. A 15kW/120kWh vanadium battery was installed as part of the SYSLAB facility at Risø DTU. The battery was installed in August 2008, and cell stacks were changed twice, first time immediately after the installation. The overall efficiency was measured at around 60% inclusive of losses for pumping. The measurement period registered no degradation performance. The battery response time from full power in one direction to full power in the other lies about 1 second. A slightly higher internal resistance was measured in the latest set of stacks. (Energy 10)
