Volvo has taken another step towards eliminating the "range anxiety" associated with most electric vehicles by developing a fast charging system that can fully charge a battery pack in just 1.5 hours.

Volvo's advancement in electric vehicle charging time was made possible by a new on-board fast-charger. The unit is not only smaller than previous designs but also operates on a three-phase supply.

As a result of that improved tech, a three-phase outlet can fully charge a car's battery in just 1.5 hours. Volvo says the three-phase system can also add 80km (50 miles) of range with just a 30 minute charge. In comparison, a full charge from a standard plug requires up to 10 hours.

"The user can 'top up' the battery pack with electricity one or more times during the day. This means that the total daily range is significantly extended, yet with the same low operating cost compared to a car with a conventional power train," says Lennart Stegland. "Giving customers more usable hours each day means that electric cars become more viable as a commercial proposition, in both the private and public sectors."

Volvo is currently evaluating the three-phase charging technology in its C30 Electric Vehicle.
