Volvo Car Corporation testing 22 kW on-board three-phase charger

(Before It's News)

Volvo Car Corporation is testing a 22 kW, three-phase on-board charger for electric cars that cuts recharging time for a current EV down to 1.5 hours.

The new charger will be installed and evaluated in a number of Volvo C30 Electric cars. The new 22 kW fast-charger is the 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 80 km 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. 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.
