Generators for Range-ExtendersCopyright: IEM
Electric Vehicles are promising concepts when developing energy efficient vehicleswith lower fuel consumption. Today’s electric vehicles can provide a rangemof up to 200km. A solution for longdistance trips is the so called range extender. The range-extender unit consists of a small combustion engine and a generator charging the battery for a specific time or delivering directly traction power to the drive train to increase the possible distance and duration of the passenger’s trip. The most important requirement for the electrical generator is a maximum power density and power-to-weight ratio in combination with a high efficiency.
