“…This value is slightly lower than that calculated with (1); it comes from a tradeoff: the higher capacity of the supercapacitor bank would improve performance but increasing the weight and cost. [21,22].…”

“…It is composed of a SC interfaced to a motor-generator unit (MGU) through a power converter, whose function is to adapt the voltage levels between SC and MGU during operation. A feasibility study of the system has been already proposed in [20], the theoretical analysis in [21], and a simulation of the whole system in [22]. This paper analyses the design of a Buck-boost power converter to manage the electric power energy exchange between the SC and the MGU.…”

This paper addresses the design of a bi-directional DC/DC power converter to interface a supercapacitor bank and a motor-generator unit. The design is based on an interleaved six legs topology in which the current is shared among six inductors to minimize their weight and cost, allowing, besides, a low switching frequency to lessen switching losses. The converter is conceived to be employed in an electric Kinetic Energy Recovery System for Internal Combustion Engine Vehicles. The system makes use of a supercapacitor as a storage system, and a motorgenerator unit connected to the drive shaft for vehicle acceleration and braking. The system uses available commercial devices, thus obtaining a cheap and high-efficiency conversion chain. It is shown how the design criteria differ from traditional interleaved converters. The same topology allows minimizing the input and output ripple and improving the reliability in case of fault as well. Losses are reduced both by sharing the currents and by a suitable control strategy, which allows more converters to be connected in parallel to increase the delivered power. Results, given in simulation, assess the stability and dynamic performance of the conversion circuit, showing a low current and voltage ripple in all operating conditions.

“…Regenerative braking system is used more actively due to its high power electric motor and high energy capacity battery pack on fully electric vehicles and its control is simpler than the regenerative braking system used on the hybrid vehicle. Control of the regenerative braking system has an important share so that vehicle safety, comfort, battery pack life and energy recovery do not adversely affect [40][41][42][43].…”

In this study, a model of a pre-transmission parallel hybrid vehicle was created in MATLAB/Simulink environment. A torque control strategy has been developed for the hybrid vehicle on the created model. The hybrid vehicle's torque control is provided by fuzzy logic and conventional rule-based control strategies. The control strategies of the hybrid vehicle have been developed based on four input parameters: accelerator and brake pedal position, battery state of charge and the operating mode of the electric motor. The regenerative braking system of the pre-transmission parallel hybrid vehicle has been provided with a fuzzy logic control strategy in both vehicle structures. In the fuzzy logic torque split controller, a control algorithm has been created in which the safety, performance and fuel consumption values of the vehicle meet at the optimum point. Under different driving cycle conditions, the effects of control strategies on engine operating points have been examined and average fuel consumption values have been obtained. In the control of the parallel hybrid vehicle with fuzzy logic method, it has been obtained that it provides 12.87%, 6.62%, 2.27% and 6.23% fuel savings under FTP-75, NEDC, EUDC and ECE-15 driving cycle conditions, respectively. It has been observed that the vehicle cannot provide sufficient performance in US06 driving cycle conditions with the use of conventional rule-based control strategy.

“…The feature of engine shut‐off/startup in full HEVs reduces fuel consumption during idling 24 . The addition of an electric drivetrain to the HEV also enables kinetic braking energy recovery and driving of the wheels solely by the electric propulsion system when the torque demand is low 25‐27 . By charging from the grids, a PHEV can emit less pollutants than a conventional HEV, reducing GHGs by 40% to 65%, NOx by 25% to 55%, and gasoline consumption by 45% to 80%.…”

Summary The transportation sector consumes a large amount of fossil fuels consequently exacerbating the global environmental and energy crisis. Fuel‐cell hybrid electric vehicles (FCHEVs) are promising alternatives in the continuous transition to clean energy. This article summarizes the recent advances pertaining to the optimization and cutting‐edge design of fuel‐cell hybrid electric vehicles, especially the fuel cell + battery hybrid topology, and discusses current technological bottlenecks hindering the commercialization of FCHEVs. The development of HEVs, markets, environmental and economic benefits, components, topologies, energy management strategies, degradation mechanisms, and safety standards of FCHEVs are reviewed. Proton exchange membrane fuel cells constitute the mainstream and most mature fuel cell technology for automobile applications. Battery hybridization is currently favored among the available FCHEV topological designs to improve the dynamic response and recover the braking energy. Energy management strategies encompassing logic rule‐based simple methods, intelligent control methods, global optimization strategies, and local optimization strategies are described, and issues and challenges encountering FCHEVs are discussed. In addition to promoting the construction of hydrogen supply facilities, future efforts are expected to focus on solving problems such as the high cost, durability of fuel cells, cold start, lifetime of batteries, security and comfort, system optimization, energy management systems, integration, and diagnosis of faults. This review serves as a reference and guide for future technological development and commercialization of FCHEVs.
