Future of Flow Batteries in Electric Vehicle Applications

Abstract

Electric vehicles are used nowadays to reduce carbon emissions and green house gases. The main challenge in the electric vehicles is the energy storage systems. For battery operated vehicles, the increase in charging time is the major concern and range of the vehicles for a single charge is not satisfied. This leads to restrict the commercialization of electric vehicles. To overcome this, researchers and industry peoples has developed a hybrid vehicle technology which contains both electric and internal combustion engines. The efficiency of the hybrid vehicle is increased when it is incorporated with IC engines. But still the energy storage issues are censorious. Now the potential area in the energy storage systems is flow batteries. The main advantage of the flow batteries is fast charging tendency. Refuelling is possible only in case of flow batteries among all energy storage devices used in electric vehicles. This paper provides the study of flow batteries used in electric vehicles and comparison of different flow batteries for electric vehicle applications.
