Electric Vehicles


As electric vehicles (EVs) take a greater share in the personal automobile market, their penetration will bring potential challenges to electric utilities especially at the distribution level. Research is being conducted at VT-ARI to evaluate the impacts of charging EVs in a residential distribution network, which will create new load peaks at the distribution transformer and may result in severe transformer overloading.

In addition to the EV research, VT-ARI also looks at the optimal sizing of battery storage for both community-scale and large-scale applications. This area of research involves several battery technologies, for example, ice storage, sodium sulfur battery and compress air energy storage.
