“…The new proposed PI gives better results compared with ECMS in case of energy consumption and operational cost, but it has higher energy and operational cost with state-based energy and original PI strategies. Bizon et al 97 proposed four new control strategies for stationary and vehicle applications based on load following and maximum efficiency point tracking in order to control fuel consumption rate and enhance the FC net power availability. Results indicate that the 12% FC net power increased by using maximum efficiency point tracking control and load following control reduces battery size, and it will operate in charge sustaining mode.…”

Summary Depletion of earth's petroleum resources, greenhouse gas emissions, and global warming issues are caused by the conventional vehicles around the globe. In recent years, automotive industries focus on emerging alternative energy sources to mitigate the relying on fossil fuels so as to reduce global harmful emissions. Researchers have focused on the different aspects of hybrid and battery electric vehicles, such as energy management, regenerative braking control, and architecture of power electronics. This paper emphasizes on review of various energy management systems (EMSs) based on fuel cell hybrid electric vehicles (FCHEV) in combination with two secondary energy storage systems like batteries and ultracapacitors to provide high‐performance energy storage system. The performance of the FC–battery–ultracapacitor with various types of energy management schemes and experimental investigations is reported in this paper. This paper provides various braking control schemes to alleviate the hydrogen utilization of an FCHEV in connection with batteries and ultracapacitors and furthermore gives thorough investigation of FCHEV on their energy utilization, configuration, and EMSs developed by different analysts. This study focuses on energy allocation schemes, experimental approaches, recovery of regeneration, and EMS for next generation hybrid electric vehicles.

“…It is mandatory for a hybrid system to include an ESS which stores the excess energy from the RES in order for it to be used to supply the load during a lack of RES power [42][43][44][45]. ESS devices are usually batteries and ultracapacitors [42]. Batteries are used as energy storage devices (having specific energy higher than that of the ultracapacitors), ensuring energy needs are met for a longer period [43].…”

Two Hybrid Power System (HPS) topologies are proposed in this paper based on the Renewable Energy Sources (RESs) and a Fuel Cell (FC) system-based backup energy source. Photovoltaic arrays and wind turbines are modeled as RESs power flow. Hydrogen and air needed for FC stack to generate the power requested by the load are achieved through the Load-Following control loop. This control loop will regulate the fueling flow rate to load level. A real-time optimization strategy for RES/FC HPS based on Extremum Seeking Control will find the Maximum Efficiency Point or best fuel economy point by control of the boost converter. Therefore, two HPS configurations and associated strategies based on Load-Following and optimization loops of the fueling regulators were studied here and compared using the following performance indicators: the FC net power generated on the DC bus, the FC energy efficiency, the fuel consumption efficiency, and the total fuel consumption. An increase in the FC system’s electrical efficiency and fuel economy of up to 2% and 12% respectively has been obtained using the proposed optimization strategies compared with a baseline strategy.

“…Other methods are preferred in the literature with real-time on-line implementation objectives: an on-line optimal control approach [11] with an adaptive principle (equivalent consumption minimisation strategy -ECMS [12]) or heuristics and rule-based approaches (Fuzzy Logic [13] and type-II optimized Fuzzy Logic [14] possibly in combination with a genetic algorithm 75 [15] or adding an adaptive mechanism [16]), in order to minimise hydrogen consumption by the fuel cell system. Control strategies based on load following also have been experimented in [17]. The solutions obtained by these approaches are suboptimal due to their non-linear formulation of the problem or the setting of some parameters generally involving important computation 80 times.…”

Hybrid Electric Vehicles are becoming more and more prevalent for eco- elling has been developed that reflects the functioning of the Hybrid Electric Vehicle energy chain, using an exact method to provide an optimal solution that corresponds to hydrogen consumption. Simulations were performed on di↵erent realistic mission profiles that showed a significant gain in solution quality and computation time compared with other approaches presented in the literature. Since the quality of solutions depends on the reliability of input data, including disruptions, a robustness study also is carried out.
