Overview
Topic status: We're looking for students to study this topic.
Current electric vehicle designs have limited range due to the low energy density of batteries compared to the fuel used by internal combustion engine vehicles. Batteries have long recharge times and a limited lifespan compared to the relatively fast process of refuelling a fuel tank. This largely hinders the acceptance of electric vehicles. Therefore, reducing energy consumption of electric vehicles can lead to wider acceptance and adoption of electric vehicles, thus being equally important to the overall objective of GHG emission reductions in Australia.
Recent studies based on car navigation systems for fuel efficiency are showing successful results. One of the techniques used is avoiding traffic congestion through a time priority route assisted by up to date traffic information. Another method is eco-driving, achieved by advising the driver of more fuel-efficient driving techniques. The third method is an ecological route search system that advises drivers on the most fuel efficient route to a destination. Each of these methods has strengths and weaknesses, requiring inputs from various sources which may not be available at all times.
Issues surrounding the energy efficiency of electric cars are less studied and understood than those of traditional vehicles. This research will develop similar techniques for electric vehicles to maximise the energy efficiency of these types of vehicles. However, the variables that have influence over fuel consumption may be largely different from these affecting energy efficiency for traditional vehicles. For instance, acceleration affects fuel consumption differently between internal combustion engines and electric engines. For instance, electric motors can speed up from zero to full output within a few seconds, with no additional electricity consumption. In addition, the electricity may be recharged while the vehicle is coasting. In addition to fuel efficient route suggestion and navigation, dedicated short range communication (DSRC) between vehicles and infrastructure may provide the necessary communication between vehicles to improve energy efficiency through driver assistance and behaviour modification.
