We define "extenders" as a class of robot manipulators worn by humans to augment human mechanical strength, while the wearer's intellect remains the central control system for manipulating the extender. Our research objective is to determine the ground rules for the design and control of robotic systems worn by humans through the design, construction, and control of several prototype experiment...

Extended-range electric vehicle is considered to be the ideal transition type for electric vehicle. The optimal operation curve control strategy was proposed for a 12 meter-long range extended electric bus. With exponential function inertia weight adjustment and local chaos substitution, an improved chaotic particle swarm optimization algorithm was applied to optimize the key parameters of ener...

To reduce carbon emissions, hybrid-electric aircraft could replace conventional turboprop on regional operations. Because of the limited energy density provided by batteries and requirements concerning reserves for operations under instrument flight rules (IFR), a range extender will be required to achieve commercially relevant ranges. In serial hybrid concept with electric motors driving prope...

Electric vehicle is considered to be the solution for energy crisis and environment pollution in individual transportation. However, electric vehicles are still not competitive with conventional vehicles limited by the driving range with the state-of-art power battery technology. Therefore, energy efficiency is of crucial importance for battery electric vehicles due to the limited stored energy...

All-electric vehicles remain far from reaching the market share required to meaningfully reduce transportation-related CO2 emissions. While financial and technological adoption barriers are increasingly being removed, psychological insufficiently addressed. Here we show that car owners systematically underestimate compatibility of available battery ranges with their annual mobility needs this u...

This paper presents an algorithm that has been developed to estimate the residual range of an electric vehicle, i.e., the distance that can still be covered with the energy stored inside the battery. The algorithm takes into account the complexity of the behavior of electrochemical batteries, with special reference to lead-acid batteries, as well as the main issues related to different driving ...

GPS data for a year’s worth of travel by 255 Seattle households illuminate how plug-in electric vehicles can match household needs. The results suggest that a battery-electric vehicle (BEV) with 100 miles of range should meet the needs of 50% of one-vehicle households and 80% of multiple-vehicle households, when charging once a day and relying on another vehicle or mode just 4 days a year.
