Few U.S. homeowners who are interested in owning electrical vehicles are equipped to charge them, a survey found on Tuesday.
More than three-quarters, 78%, of potential buyers of electric cars like the Chevy Volt, right, do not have the 240-volt electrical outlets in their garages that can quickly charge such vehicles, according to a survey by diversified U.S. manufacturer SPX Corp., which makes equipment to charge electric vehicles.
However, 99% of respondents lived in homes that could have the necessary outlets - also commonly used for heavy appliances like washing machines -installed.
The survey highlights an obstacle to wider adoption of electric cars, which are gaining in popularity but still account for a small portion of overall U.S. car sales.
The short range of current models and a lack of charging infrastructure, are obstacles to a large electric fleet, advocates have said.
