Since 1985 zinc-flow-batteries have been used to power electric-vehicles (EVs) in capacities between 5 kWh and 45 kWh at voltages between 48 V and 216 V. About 50000 kms of testing experience, partially in direct comparison with originally assembled lead acid batteries, showed results with zinc-flow battery equipped EVs which were significantly better than was expected. Referring to about the same battery weight, a two- to three-fold range was experienced with the zinc-flow-system independent of the driving cycle and independent of the battery capacity compared.<<ETX>>
