Abstract.Here we present one of the more complex models for studying the stability of driving an electric car with electromechanical differential systems. The purpose of simulation is to choose a structure of the control system for a velocity control on driven wheels (an algorithm of a differential) most appropriate for the driver. This type of goal is particularly important in the case of a disabled driver sitting in a wheelchair. The modeling takes into account both the mechanical and electric structure of the vehicle, and finally the human element -a simple model of human impact on the steer by a wire system. Modeling and simulation have used MBS package (SimMechanics). The results of the simulation have showed the best algorithms of an electromechanical differential for the velocity control of rear drive wheels: with setting a velocity difference or with an average velocity controller in the point A of the centre of a car front axle.

“…A resistor R s connected in series with a parallel RC branch models an ohmic drop and polarization effect [22,23]. A discharge capacity and internal resistance variations resulting from change in discharge current and temperature are modeled as in [25]. Presented model is extended by adding dynamic thermal modeling.…”

Abstract. This paper discusses benefits of introducing an ultracapacitor (UC) bank into a battery electric vehicle (BEV) powertrain. The case of 12kWh LiFePO4 battery pack is studied quantitatively. Simulation results refer, inter alia, to three main scenarios: fresh cells, half-used battery cells, and half-used ultracapacitors and batteries. Thermal modeling is incorporated into the simulation. Data from real world are considered: various driving cycles recorded using GPS receiver (incl. elevation), discharge curves from battery manufacturer, and UC equivalent series resistance (ESR) variations due to cycling according to real data reported in papers. Cost, as well as gravimetric and volumetric issues are presented. The key decisions referring to an energy storage for BEV being currently designed within the frame of ECO-Mobility Project are highlighted.

“…The major disadvantage of the conventional battery/SC [7], [28] and the SC/battery HESSs [11] [31], [34] is that an energy source must operate alongside the DC-DC converter, thus aggravating the energy loss in the power converter. The hybrid topology HESS that incorporates an additional power diode into the battery/SC HESS solves the aforementioned problem [6].…”

“…Size should also be considered carefully when designing a suitable HESS for EVs [27], [28]. An ESS with a single DC-DC converter configuration is preferred due to the small size and low cost of the DC-DC converter [29]- [31].…”

This paper proposes a novel compound-type hybrid energy storage system (HESS) that inherits the unique advantages of both battery/supercapacitor (SC) and the SC/battery HESSs for electric vehicles (EVs). Eight operation modes are designed to match this system. A mode control strategy is developed for this HESS on the basis of these modes, and five classes of operation modes are established to simplify this strategy. The mode control strategy focuses on high operating efficiency and high power output. Furthermore, the compound-type HESS is designed such that the SC is the main priority in braking energy absorption. Thus, this HESS can operate efficiently and extend battery life. Simulation results also show that the compound-type HESS can not only supply adequate power to the motor inverter but can also determine suitable operation modes in corresponding conditions. Experimental results demonstrate that this HESS can extend battery life as well. The overall efficiency of the compound-type HESS is higher than those of the battery/SC and the SC/battery HESSs.
