The vanadium flow battery was coupled to a vehicle battery charger. With success
The vanadium flow battery technology was tested with a stand-alone charger in Australia. An AC charger was coupled to a 5 kW/30 kWh vanadium redox flow battery (VRFB)
powered by a 3 kW photovoltaic system installed on a roof. It could provide an efficient charging network for electric vehicles as the flow battery is well suited to capturing and storing large amounts of renewable energy, enabling stable electricity generation.
"The vanadium electrolyte does not degrade, which means that thousands of vehicle batteries can be charged from the station. The long life of the VRFB, which exceeds 20 years, makes it one of the most durable and sustainable ways to store renewable energy. At the end of the battery's mechanical life, the vanadium electrolyte can be reused indefinitely."
This trial removes one of the barriers to the adoption of electric vehicles in Australia, namely the distance between and availability of different charging stations.

Although it is only a trial, it appears to be successful. Indeed, when there are long distances between charging points, they must always be ready for use. The long storage time is therefore essential.
