This paper presents the design and the experimental tests of an ultra-capacitor pack used as an energy storage system in a small hybrid electric vehicle. This design consists in calculating the capacitance and the power of the capacitors, which are necessary to store kinetic energy during deceleration of the vehicle and then to accelerate the vehicle. In a second part, experimental tests are achieved...
The need for service passenger cars, like taxies and governmental vehicles, to work in central Tehran that can produce less emission has been the main drive behind this research. A series hybrid pneumatic vehicle based on Iran manufactured Samand Passenger car was developed using commercially available components. The idea is to use as much standard parts as possible to reduce the development and...
With breakthroughs in battery technology, plug-in hybrid electric vehicles (PHEVs), jointly powered by an electric drive and an internal combustion engine are becoming a realistic alternative. In a PHEV, the battery is charged by the grid and the electric machine plays the major role in the vehicle drive so that the engine is only required to provide extra torque when accelerating and to drive the...
Much attention has been paid to electric vehicles recently due to environmental concerns. The plug-in hybrid electric vehicle (PHEV) consisting of both electricity storage and gasoline tank is welcome to electric vehicle market. In the PHEV system, the electric machine drive is one of the key issues. The ideal tendency is to use the drive machine over the entire torque/speed range with high starting...
