Abstract

Like with the passenger car and transit bus markets, school buses can benefit from plug-in hybrid technology. Advanced energy corporation established the plug-in hybrid electric school bus (HESB) project to create the demand for plug-in hybrid school buses required for a bus manufacturer to invest in the development of this technology. Nationwide 12 school districts in NY, PA, VA, DC, NC, SC, FL, IA, AK, TX, WA, and CA have purchased 19 plug-in hybrid buses in the project with all buses to be delivered by the end of 2007. Each bus is a type-C school bus with a VT365, 200-215 hp diesel engine by IC Corporation, a 25/80-kW AC induction motor and hybrid drivetrain from Enova Systems, and a 330-V Li-ion battery pack from Valence Technologies. The total cost of each bus ranges from $200,000-$220,000, including an estimated $140,000 premium for the plug-in hybrid system. This paper addresses the specific challenges that face the transportation industry as a whole, summarizes earlier studies that demonstrate the technical and economical feasibility of plug-in hybrid school buses, describes the HESB project, and draws future plans to show why hybrids are an excellent solution for the school bus market.

利用利基市场的插电式混合动力市场转型:校车

与乘用车和公交巴士市场一样，校车也可以从插电式混合动力技术中受益。Advanced energy公司为了创造对插电式混合动力校车的需求，设立了插电式混合动力校车(HESB)项目，以使巴士制造商投资开发这项技术。在全国范围内，纽约州、宾夕法尼亚州、弗吉尼亚州、华盛顿特区、北卡罗来纳州、南卡罗来纳州、佛罗里达州、印第安纳州、AK州、德克萨斯州、华盛顿州和加利福尼亚州的12个学区已经在该项目中购买了19辆插电式混合动力巴士，所有巴士将于2007年底交付。每辆巴士都是c型校车，配备IC公司的VT365 200-215马力柴油发动机，Enova系统的25/80千瓦交流感应电机和混合动力传动系统，以及Valence Technologies的330 v锂离子电池组。每辆巴士的总成本在20万美元到22万美元之间，其中包括插电式混合动力系统的大约14万美元的溢价。本文阐述了整个运输行业面临的具体挑战，总结了早期的研究，证明了插电式混合动力校车的技术和经济可行性，描述了HESB项目，并绘制了未来的计划，以说明为什么混合动力是校车市场的一个很好的解决方案。
