The research of electric vehicles (EVs) has gained more and more attention in recent years in both industry and academia, and new registrations of EVs increase rapidly, while the long delay at the convenient but crowded charging stations may discourage many drivers from switching to EVs. To address the problems, we propose a novel dynamic pricing policy that allows charging stations to adjust their...
There are many uncertainty factors when the electric vehicle (EV) drives in the complicated variable circumstance. It makes the control effect of some control modes non-ideal. To ensure the robustness of the closed-loop system under the presence of uncertainties, such as parameter perturbation and unknown model dynamics, and to minimize the effect of disturbances, the μ synthesis robust control is...
Based on comprehensive analysis of differential principle, a novel driving and control system for a direct-wheel-driven electric vehicle (EV) is presented in this paper. Without differential gears, direct-wheel-driven EV has to employ complicated differential algorithm for steering, which remarkably increased the difficulty of the control system of EV. The system proposed in this paper has changed...
Based on the analysis the driving system of motors in series, it indicated that the system simplifies the structure and realizes the effective self-action differential when the electric vehicle(EV) runs on the level road without any variety or at low velocity. When the EV runs on the variational road, especially the friction force is variant, the EV is unstable according to the character of the permanent-magnet...
Aiming at the main problems of electric vehicle (EV): short driving range, short life of batteries, and variation of model parameters, based on constructing the main circuit diagram of the EVpsilas control system, the mathematical model of regenerative-braking process was established, and a novel regenerative-braking controller was designed, which combined neural network (NN) with traditional sliding...
Based on analyzing the principle of position- sensorless control for brushless DC motor (BLDCM), a control system employing back-EMF method was designed for the position-sensorless electric vehicle (EV). In order to eliminate the influence on back-EMF detection circuit from motor neutral point and RC filter, the system disconnected the reference point of detection circuit from battery cathode, and...
In order to deal with the main problems of electric vehicle (EV), such as the short driving range, the short life of batteries, the variation of the road state and driving mode and so on, based on constructing the main circuit diagram of the EV's control system and researching driving and regenerative braking process, the mathematical model of the system was established, driving and regenerative braking...
