Volvo Shows Plans for Three Electric Vehicles with Range-Extending Engines—or Hybrids

Volvo currently has its hands in several green technology pots, and has either developed or is developing everything from electric C30s to a flywheel hybrid system to a diesel-electric plug-in hybrid system. This week, the company announced that it’s working on yet another system (three, actually): three unique range-extended electric drive setups. Volvo is doing the development with the support of the Swedish Energy Agency and the European Union. A quick refresher: range-extended electric cars are electric vehicles with an onboard power generator—whether that’s a small gas engine or diesel.

Volvo’s three “technical concepts” all employ the similar hardware—a three-cylinder combustion engine and a 111-hp electric motor—but differ in how the engine assists the electric motor. The company claims that for each of its three range-extended concepts, effective range is increased by over 600 miles over each car’s electric-only range. There is no word about when we can expect to see one of Volvo’s range extender systems powering a production model, but if one is green-lit for production, it’ll be many years until a car so equipped hits the road.

Technical Concept I

The first concept, a modified Volvo C30, uses a series-connected range extender. The system consists of a 60-hp three-cylinder engine, the aforementioned 111-hp electric motor, and a 40-kW generator. The tiny, rear-mounted engine is not mechanically linked to the drive wheels at all (the Chevrolet Volt’s engine can send power to the wheels under specific circumstances) and simply turns the 40-kW generator that charges the car’s battery pack, which the electric motor draws power from (the power flows in a series).
