The Volvo Group sees opportunities to accelerate the development of a parallel hybrid system, especially for vehicles that accelerate and brake frequently. This is clearly a good match for construction machines, in addition to city buses and garbage trucks. While the technology might appear in trucks and buses fairly quickly, from a few months to a few years in trucks and buses, for construction equipment the commercial availability might have to wait a little longer. The hybrid system under development is comprised of a combined start motor, drive engine, generator, electronic control unit, batteries and diesel engine. The batteries are recharged by regenerative braking and directly by the diesel engine when possible. Wheel loaders, a particularly attractive application, might show fuel savings of up to 50%.
