Oerlikon Fairfield offers a complete hybrid-electric drivetrain technology system with energy recovery from engine to wheel. Components of the system include an engine-driven generator to produce electrical power; an ultracapacitor bank that recovers energy during operation; a software control unit; dual inverters integrated into the front and rear axles for simplified wiring packages; and four high-power density traction motor drives at each wheel end that allow for higher motor speeds and improved performance over various ground speed ranges. The system offers up to 30% fuel-economy improvement; other benefits include electrically driven auxiliary drives and the ability to add engine start-stop technology.
