The paper presents the comparison and the experimental validation of three ultracapacitor (UC) circuit models of the Maxwell Boostcap® module. The more advanced layout takes into account the nonlinear dependence on the terminal voltage, the internal losses and the charge redistribution effects by suitable RC branches. By means of different types of charge tests, the more convenient circuit layout...
This paper presents the mathematical model of the useful movement of the electric vehicles. On the mathematical model basis it is built the structural diagram and the SIMULINK model associated of the useful movement. The SIMULINK model is used to calculate the energy consumption for different running regimes and different route configurations and to identify energy efficient train control methods.
A novel controller for a switched capacitor (SC) bidirectional DC/DC converter is proposed for plug-in hybrid electric vehicle energy storage systems, with simultaneous step-up and step-down output voltages. The novel control strategy enables simpler dynamics compared to a standard buck converter with input filter, good regulation capability, lower source current ripple, ease of control, and continuous...
Zero-emission vehicles are defined as cars with no gaseous emissions, such as NOx, CO, HC and particulate matter. In this paper, the design of the electrical drive train of a zero-emission vehicle, comparable with the smart for two car, is given. The design of the drive train is evaluated by MATLAB/Simulink simulation according to the calculated mass and losses of the drive train components. The loss...
