System Overview

  • Parallel hybrid using diesel and electric power
  • In high-demand phases, electric power and diesel power can assist one another
  • The E-Motor can use excess diesel power to generate electricity
  • Power regeneration is possible through braking (inertia or vehicle)

RePTO drive with MasterClutch™

  • Installed between diesel engine and E-Motor/generator providing mechanical interface to direct-mount E-Motor/generator
  • Single and dual tower options available for driving motor generator, hydraulics, or other auxiliary loads
  • MasterClutch™between diesel and RePTO drive for electric-only mode and power regeneration
    • Power generation through PTO/PTI in various operating states
    • Prevents engine back-driving during electric-only operation

Power Shift Transmission and Controller

  • Twin Disc power shift transmissions
  • Mechanical interface to direct mount RePTO and thus E-Motor/generator
  • State-of-the-art microprocessor-based controller manages transmission operation

Hybrid Controller

  • Manages power distribution, interfacing with high voltage equipment and customer’s vehicle/machine controller

E-Motor/Generator, Inverter, High Voltage Equipment

  • Selection based on application characteristics
  • Controlled and monitored by hybrid controller

Energy Storage

  • Selection based on application characteristics
  • Controlled and monitored by hybrid controller
