Volvo has been successful in creating a three-phase on-board charger that is small enough to be fitted in an electric vehicle, reducing the full charge time in an electric C30 model to 1.5 hours (compared to 8 – 10 hours for single phase supply).
C30 is being trialled in Europe and results have been promising. The 22 kW fast-charger is the world’s first on-board three-phase supply charger. A new Siemens motor gives peak power of 89 kW (120 hp) and a torque of 250 Nm.
“Adding the innovative fast charging solution will radically improve the time and mileage for the daily usage of the car. Even a quick 10-minute plug-in adds power for another 20 kilometres of driving,” says Lennart Stegland,
Siemens is the main supplier of electric propulsion power train components for Volvo’s forthcoming Scalable Product Architecture (SPA) platform, which enables vehicle electrification at all levels – from different kinds of hybrids to pure electric drive, without intruding on interior or load space.
