Fargo, ND – The flexibility of John Deere Electronic Solutions PD300 power inverter shines in yet another application. In Vanner Inc.’s Increased Accessory Power 2™ (IAP2) system the PD300 powers accessory components like electric air conditioning systems, electric air compressors, electric heat, and electric power steering systems. The PD300 accomplishes this by converting high voltage DC power from the Allison H 40/50 EP™ hybrid systems to high voltage commercial 230V AC power.
So what’s so great about this approach? Coupled with the Allison H 40/50 EP™ parallel hybrid propulsion system, this integrated system allows accessories to be driven electrically at a single high efficiency point rather than operating at a wide range of speeds with varying efficiencies. The conventional rubber belt drives are eliminated. “Removal of hydraulic loads that have to operate in the engine speed range are generally going to be less efficient,” said David Loken, Senior Electronic Design Engineer at JDES. “In the automotive world, electric vs. hydraulic steering assist, electric water pumps, electric AC, etc. are replacing belt-driven loads.” At a system level, better fuel economy, reduced emissions and lower maintenance costs are attractive benefits to automotive and bus industries.
“Adding IAP2 powers all electrical accessories providing large bus maintenance saving and additional fuel savings. Full accessory electrification of a transit is the single most advantageous option a transit authority can realize that will improve fuel economy, reduce emissions and lower maintenance costs,” said Steve Funk, president of Vanner. “The Allison H 40/50 EP™ hybrid already has a proven track record as a reliable sustainability solution. JDES and Vanner brought together their best engineering talent to develop IAP2 for the Allison H 40/50 EP™. IAP2 improves on the hybrid’s efficiency by distributing the hybrid electrical power throughout the entire bus’s accessory system. Vanner is proud to partner with JDES.”
