Increased Accessory Electrification for Hybrid Buses

New Flyer said Friday that it is now offering Allison Transmission’s IAP II – for increased accessory power, version two – as a “total electrification option” for components such as electric air condition on buses with Allison H 40 EPTM and H 50 EPTM hybrid drives.

“The option uses electrification to power accessory components for additional fuel economy,” New Flyer says. “The system improves on the electric hybrid’s efficiency by distributing the electric hybrid power throughout the bus.”

Allison’s IAP II is further described as “a customizable electric distribution platform that provides power from the Allison electric hybrid system to accessory components such as electric air conditioning, electric air compressors, and 24-volt DC power steering systems.”

IAP II, New Flyer adds,

  • allows accessories to operate at the most efficient speeds, improving fuel economy; and
  • replaces alternator and belt with a more reliable and efficient DC-DC converter, resulting in improved fuel economy.

Brake responsiveness is improved too, as is low-speed maneuverability, due to smoother power steering. Passenger compartments cool more quickly, with no engine strain and less fuel burn.
