In modern transportation, electric bicycles play an increasingly important role e.g. in urban traffic as well as for commuting and recreational activities. Nevertheless, a limiting factor of electric bicycles is the battery capacity. One approach to increase cruise range is regenerative braking, where kinetic energy is recovered during the braking process and used for recharging the battery. In this...
Energy storage systems (ESSs) that are composed of batteries and supercapacitors are increasingly being used as receptors for regenerative braking energy (RBE) in railway applications. These ESSs can be installed on-board the rolling vehicle, or off-board wayside, or mixed on- and off-board. This paper presents a comparison of three different ESSs topologies applicable in trains powered by a dc feed...
Regenerative braking technology is crucial for electric vehicle applications. Where, the motor is used as a generator to charge the vehicle's battery. However, the regenerated energy is not fully returned to the battery. Some power losses are experienced in between such as losses in the motor's armature and switching losses. The motor drive system described in this paper has an energy storage system...
In this paper we present an easy-to-implement model that allows to determine the potential energy savings of regenerative braking (also: recuperation) for Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) by exploiting Inter-Vehicle Communication (IVC). The proposed model has been designed to be applied within different braking scenarios: approaching traffic lights, stop-and-go, emergency...
As the cruising range is one of the main disadvantages of fully electric vehicles compared to vehicles with combustion engines, its improvement is an important research challenge momentarily. The recuperation of the braking energy is one research approach. In this paper, the theoretical potential of recuperation is discussed and a survey of recuperation strategies is presented. The recuperation energy...
Improving the cruising range is one of the main research challenges regarding fully electric vehicles. The optimisation of the regenerative braking can help to enlarge the range without an extension of the accumulator capacity. In this paper, a general overview of recuperation strategies is given. The recuperation energy and therefore the obtained range extension of currently available electric vehicles...
In battery-operated electric vehicles, a regenerative brake system is an additional feature that recovers kinetic energy back to the battery energy storage. Due to losses in the cyclic charge/discharge of battery characteristics such processes give low energy conversion efficiency. Supercapacitor, on the other hand, has an advantage over battery in terms of recovering an intermittent energy like a...
The ability to regenerate energy when braking is a valuable advantage of hybrid and fully electric vehicles. How much energy that can be regenerated depends mainly on the car driving and the capacity of the driveline. Detailed studies of possibilities for brake energy regeneration in real world driving are needed to better understand the potential gains of car-electrification since test cycles do...
In this paper, a plug-to-wheel energy balance is made of battery electrical vehicles. The study is based on real data from a two years continuous monitoring of five Peugeot iOn cars, that was performed in Belgium since June 2011, with the financing and support of Electrabel. Different driving styles, trip profiles, type and intensity of use were observed, leading to different energy patterns. The...
The mu synthesis robust controllers for hybrid-power EV are developed to ensure the robustness of closed-loop system under the influence of uncertainties, such as the parameter perturbation and the unmodeled dynamics, and to minimize the effect of the disturbances, such as the variation of the battery and ultra capacity voltage, the road state, and the driving mode of vehicle. The simulated and experimental...
The limited range of Battery Electric Vehicles (BEV) is a major restraint for their market acceptance. This paper shows that efficiency — hence range — increase can be achieved by optimal distribution of driving and braking torque to the electric machines of an EV. Furthermore, a novel strategy for efficient recuperation of kinetic energy during the braking process of a (H)EV based on intelligent...
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...
