Volvo testing an electric car charger that only takes 1.5 hours for full range

The chief complaint about the Chevy Volt, Nissan Leaf and other all-electric vehicles is the time it takes to charge their batteries. Volvo aims to change that.

The Volvo C30 electric vehicle will implement the new speed charging system.

Gripes over the cost of gas since Hurricane Sandy have given way to worrying about getting any gas at all, or getting it without waiting 5 hours. Could electric vehicle sales, which have slowed in the last half-year, benefit? Possibly.

But they’ve still got a way to go.

The Nissan Leaf electric car I tested earlier this year failed to give me a buzz, and part of the reason I didn’t like it was because a typical charge delivering a day’s worth of driving took 6 – 8 hours. During one outing where I found myself with 12 available miles showing and 15 actual miles to home, I found a building in a mall with an outdoor socket and plugged in. 90 minutes later, I had an additional 9 miles showing on my meter, and was able to make it home.

Barely.

Volvo aims to take 90 minutes and crunch a full-charge out of it, and its new fast-charging rig operates six times faster than any on-board devices. Its new charger will be installed and evaluated in a number of Volvo C30 Electric cars soon, the company says.

We know that short recharging times and extensive operating range are a necessity for potential electric car consumers,” says Lennart Stegland, Vice President Electric Propulsion Systems, Volvo Car Corporation. “The fast-charging unit helps cure what is known as ‘range anxiety’ since the car can be more easily recharged during the day. And even if you don’t have enough time for a 1.5-hour charge, plugging in for just 30 minutes will give you enough power for another 80 kilometres (49 miles) of driving,

The new 22 kW fast-charger is the world’s first charger that operates on a three-phase supply and is small enough to be fitted in an electric car. It offers the car owner two possibilities:

• Using a three-phase outlet with 32A gives an a 50-mile range in 30 minutes. A full charge takes 1.5 hours.

• Plugging into an ordinary single-phase 230 V household outlet gives a charging time of 8-10 hours, depending on the available current.

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.”
