New Flyer of America Inc. announced immediate availability of Increased Accessory Power II for the Allison Transmission Hybrid H 40 EP™ and H 50 EP™ propulsion systems. The option uses electrification to power accessory components for additional fuel economy.

“We are pleased to offer immediate availability of another fuel-saving technology for the New Flyer Xcelsior,” said Wayne Joseph, president, New Flyer of America. “Through exploration of new and innovative propulsion options, we bring greater efficiency, sustainability, and advanced technologies to our customers, helping drive leaner, greener operations.”

Increased Accessory Power II (IAP II™) is 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 24VDC power steering systems. The system improves on the electric hybrid’s efficiency by distributing the electric hybrid power throughout the bus. Available in standard and articulated bus applications, IAP II includes either a single or dual Hybrid Beltless Alternator (HBA).

“New Flyer and Allison have demonstrated an effective partnership, dedicated integration work, and a mutual commitment to innovation.,” said Heidi Schutte, VP, marketing and sales for the Americas, with Allison Transmission. “When using IAP II with our system, fleets can expect an additional average fuel economy improvement of up to 18 percent.”

Like IAP I, IAP II utilizes a high voltage distribution module (HVDM) for intelligent control of high voltage electrical power and an HBA (or dual HBAs) for DC to DC conversion of high voltage to 24VDC. IAP II also adds an inverter that converts high voltage DC to high voltage AC that can power components while simultaneously eliminating the cost and need for the air conditioning system’s integral inverter.
