Here at EcoCAR we are challenged to develop practices to measure emissions and fuel economy and now it’s happening at a national level. It was just announced that mechanical engineers at Agronne National Laboratory received approval of SAE J1711, a revised recommended practice for figuring out the fuel economy and exhaust emissions test procedures of hybrid and plug-in hybrid vehicles (PHEVs). The approval is a major accomplishment that will encourage and support the nation’s move to electrified vehicles for petroleum savings. The new revisions are also the basis for the way that we measure fuel consumption in EcoCAR.
Mike Duoba, a principal mechanical engineer for Argonne, has led the SAE International (Society of Automotive Engineers) task force in the effort to revise the test procedures to better evaluate PHEV technologies.
Even more exciting, the U.S. Environmental Protection Agency is expected to issue a new regulation later this year that will define PHEV fuel economy reporting protocol and much of the new EPA regulation is likely to be based on SAE J1711. Now that SAE J1711 has been approved, Duoba and his colleagues are focused on supporting the development of testing standards for all-electric vehicles, known as SAE J1634.
Pretty cool! What do you think? We’d love to hear your thoughts on the challenges and benefits of having these standards in place.
