The International Energy Agency's Implementing Agreement for Cooperation on Hybrid and Electric Vehicle Technologies and Programs (IA-HEV) began in 1994 (www.ieahev.org). One of the primary objectives is to provide balanced, objective, useful information to national and local governments about how they can achieve clean air, climate change, and energy diversification objectives by encouraging the use of hybrid and electric vehicles in different market applications.
Heavy-duty vehicles encompass a wide diversity of applications and have specific technical requirements and economic boundary conditions compared to the passenger car market. Therefore, some members of the IA-HEV felt the need for setting up a specific Task on this topic. Task XII focusing on heavy-duty hybrid vehicles was initiated and approved at the IA-HEV Executive Committee meeting in October 2006. The work of Task XII formally started on January 1st, 2007 and has run until November 30th, 2010.
Task XII aims to report on the current status of the heavy-duty hybrid vehicles “playing field” and will give an view on the available and emerging hybrid vehicle technologies and on the current and expected state of the market.
A classification of heavy-duty hybrid vehicles according to purpose or operational application is agreed upon to pose fewer difficulties in combining the vehicles of Europe and the USA.
