The expected increase in the penetration of electric vehicles (EV) and plug-in hybrid electric vehicles (PHEV) will produce unbalanced conditions, reactive power consumption and current harmonics drawn by the battery charging equipment, causing a great impact on the power quality of the future smart grid. A single-phase semi-fast electric vehicle battery charger is proposed in this paper. This ...

Torque vectoring (TV) is one of the most promising technologies in vehicle dynamics control as it has the potential to provide distinctive benefits for mobility and agility of all-wheel drive ground vehicles. Especially in all-terrain driving, TV control can support both vehicle stability and driving efficiency. Within this context, the paper presents the state-of-the-art in TV control and intr...

This paper presents an experimental study of the electronic differential system with four-wheel, dual-rear in wheel motor independently driven an electric vehicle. It is worth bearing in mind that the electronic differential is a new technology used in electric vehicle technology and provides better balancing in curved paths. In addition, it is more lightweight than the mechanical differential ...

Abstract: For the characteristics of full electric propulsion, a novel kind of brake-by-wire unit is designed for electric vehicle to improve braking performance. A comprehensive brake-by-wire system including this unit is set up after its structure and principle are introduced. Then, a multi-layer fuzzy controller is proposed to regulate decelerate and wheel slip rate, and an optimal regenerat...

Electric vehicle-sharing systems have been introduced to a number of cities as a means of increasing mobility, reducing congestion, and pollution. Electric vehicle-sharing systems can offer one or two-way services. One-way systems provide more flexibility to users since they can be dropped-off at any station. However, their modeling involves a number of complexities arising from the need to rel...

High power and miniaturization of motors in an in-wheel drive system, which is installed inside the wheels of a vehicle, are required for directly driving the wheels. In addition, an efficient cooling system is required to ensure high driving performance and durability. This study experimentally evaluated the heat dissipation performance of a 35-kW-class large-capacity in-wheel motor equipped w...

The paper presents the control design of a vehicle, which is driven by four independently driven inwheel electric motors and steered by the steering system. The direction of the vehicle is based on the steering, while driving and braking are based on the electric motors. Since the direction can also be modified by the appropriate operation of the four electric motors, reconfigurable and fault-t...

Car sharing services promise “green” transportation systems. Two vehicle technologies offer marketable, sustainable sharing: autonomous vehicles (AVs) eliminate customer requirements for car pick-up and return, and battery electric vehicles entail zero emissions. Designing an autonomous electric vehicle (AEV) fleet must account for the relationships among fleet operations, charging station (CS)...

A new hybrid-drive system taking flywheel energy storage system instead of chemical battery as assistant power source for hybrid electric vehicle is put forward. According to the particular energy characteristics of flywheel system, an energy management strategy based on fuzzy logic control is also developed with overall consideration on the optimization of both ICE (Internal Combustion Engine)...
