Oerlikon Fairfield will unveil its patent-pending
hybrid electric drivetrain technology at ConExpo-Con/Agg. This technology is a complete series electric driveline system from engine to wheel featuring an innovative energy recovery system. It is the first of its type to be designed by a company specializing in drive solutions.
Major components of the system include an engine-driven generator to produce electrical power; an ultra-capacitor bank that recovers energy during operation; a custom software control unit; dual inverters that are integrated into the front and rear axles providing simplified wiring packages; and finally, four high-power density traction motor drives at each wheel end allowing for higher motor speeds and good performance over a wide ground speed range.
“We believe there are real advantages to this type of hybrid technology in off-highway applications,” said Dan Phebus, head of the business unit – Americas at Oerlikon
Fairfield. “Not only will this system provide up to 30% fuel economy improvement, but depending on the application, other benefits such as electrically driven auxiliary drives and the ability to add engine start/stop technology may have more beneficial advantages.”
