“…To guarantee the vehicle's braking performance, a friction braking system is still needed. Thus, most EVs adopt blended braking systems consisting of a motor braking system and a friction braking system [4][5][6][7][8][9]. The blended braking system has the advantages of braking energy recovery and fast response speed, as compared to the conventional friction braking system.…”

Braking torque distribution strategy is not only related to the tracking performance of the blended braking system in commanding the braking signal, but is also related to the energy utilization efficiency of the blended braking system. In this paper, a new braking torque distribution strategy is designed for a blended braking system consisting of a motor braking system and a friction braking system. In contrast to the classic braking torque distribution strategy, which adjusts the braking torque distribution ratio based on the braking strength, the newly designed braking torque distribution strategy adjusts the braking torque that is allocated to the motor braking system and friction braking system, according to the command braking torque signal, the braking actuators’ dynamic characteristics and the motor's electrical characteristics. In addition, a three‐layer controller is designed to ensure the execution of the proposed braking torque distribution strategy and the stability of the blended braking system. Compared to the classic distribution strategy, based on braking strength, numerical simulation results show that the braking energy recovery of the blended braking system has been improved by 16% in normal braking conditions and has been improved by 84% in emergency braking conditions under the new braking torque distribution strategy.

“…During driving, the kinetic energy of the vehicle can be recovered under three situations which are respectively decelerating, braking, and coasting. Compared with the decelerating and braking situations, only a few researchers studied the regenerative braking under coasting situations [26][27][28][29][30], especially for pure EVs. In [26] and [27], the regenerative braking of a HEV in coasting mode was investigated, and a braking energy recovery strategy was proposed, which applied maximum motor braking torque to speeds above a certain threshold speed, and provided only friction brakes at low speeds.…”

Under raising pressure of global energy and environmental issues in recent years, electric vehicles (EVs) have been an alternative solution of the automobile industry owing to its high energy efficiency, low noise, and zero emission. However, the short driving range is an urgent problem to be solved for EVs. Energy recovery is an important technology to improve energy efficiency and extend driving range of EVs. In this paper, an improved braking energy recovery strategy based on ideal braking force distribution (curve I) was proposed for the regenerative braking system (RBS) of a small four-wheel drive (FWD) EV. Compared with previous study, the improved braking energy recovery strategy gives more consideration to braking stability and covers broader braking situations of the vehicle. The braking energy recovery strategy is extensively validated through numerical simulations of a previously built vehicle system model under different fixed braking strength and continuously varying braking strength. The simulation results show that the proposed braking energy recovery strategy is able to effectively achieve the regenerative braking function under different braking conditions while ensuring braking efficiency and braking stability.

“…During the regenerative braking, the energy is returned from the motor to the batteries, when the inertia of the bicycle forces the motor to enter in the generator mode Nian et al (2014). At the same time, the electromagnetic braking torque is applied to reduce the velocity of the vehicle Wang et al (2012).…”

The autonomy of electric vehicles is under investigation by the scientific community,in which different solutions based on renewable energy resources, such as the photovoltaic, areproposed. A solution under study is the utilization of regenerative braking developed by theelectric motor vehicles. In this work, the addition of a regenerative braking is proposed aimingto increase the autonomy of electric bicycles. A two level, three-phase converter is applied todrive a brushless DC motor (BLDC). A comprehensive modeling of current and speed control arepresented in order to operate the machine in quadrants I and IV. The behavior of the Lithiumbattery charge is observed through its state-of-charge (SOC). Simulation results were obtainedby means of the SimPowerSystemsR©/Matlab/SimulinkR©software.
