Volvo Cars is testing a new technology to recharge electric-vehicle batteries in 1.5 hours.

The time it takes to recharge a battery and the relatively short driving ranges of today's EVs are two of the biggest obstacles standing in the way of public acceptance of the new powertrains.

Volvo said its charger operates six times faster than today's on-board devices.

"The fast-charging unit helps cure what is known as ”˜range anxiety' since the car can be more easily recharged during the day," said Lennart Steglund, vice president electric propulsion systems at the Swedish carmaker.

He added that the new charger will already provide enough battery power for 80 kilometers of driving after 30 minutes.

Volvo said the 22kW charger is the first to operate on a three-phase supply and is small enough to fit inside an EV. It plans to install the charger on several electric C30 models as it conducts its tests.

The charger needs a 32A three-phase outlet to quickly provide full power to a battery. Plugged into a normal 230V household outlet, it requires 8-to-10 hours for a full charge.
