Abstract
According to estimates by two market research companies [1], the proportion of hybrid vehicles in world vehicle registrations will increase from about 1.25 percent in 2010 to a maximum of 18 percent in 2020. A recent EURELECTRIC report [2] calls the plug-in hybrid “a logical development of the hybrid vehicle,” and envisions a potential PHEV market share in Europe of 8 to 20 percent by 2030. The global market for PHEVs is estimated to reach 130,000 vehicles by 2015 [3]. In light of this trend, standardization is needed. The primary objective of standardization is to lower development and production costs and ensure consistent quality, while at the same time satisfying all the demands of practical vehicle operation [4]. Adequate standards for measuring the performance or fuel consumption as well as the emission measurement standards do satisfy customer demand for comparable figures between hybrid models and conventional vehicles. The main objective of this paper is to provide a new adapted type approval test procedure for homologation purposes to better reflect the real environmental benefits of this type of vehicles. The driving cycle is based on the New European Driving Cycle. The environmental assessment together with the new Ecoscores [5] of retrofitted large family cars and SUV’s are evaluated.
Highlights
In the search for alternative fuels, hybrid vehicles can contribute to reduce airborne emissions in the road-traffic sector
Plug-In Hybrid Electric Vehicles (PHEVs) use the same technology as the standard hybrids on the road, but have a larger battery pack that can be recharged by plugging into a standard home electrical outlet
The retrofitted PHEV that can run only 30 pure electric kilometres will only run the first two ECEcycles in charge-depleting mode, the rest will be ran in the standard hybrid mode
Summary
In the search for alternative fuels, hybrid vehicles can contribute to reduce airborne emissions in the road-traffic sector. The fuelsaving effect of hybrid vehicles, depends heavily on their operating conditions. The adoption of an automatic start-stop system, can reduce fuel consumption in certain operating conditions with only a limited degree of expense. Further potential can be found in the use of a starter generator as a means of boosting the power from the internal combustion engine [6] (mild hybrid). These two alternatives are likely to be of interest mainly to operators of vehicle fleets on delivery work
