“…For the proposed HESS configuration, we take V SC.min = 0.5 V SC.max that is most often accepted in practice [10], while for other switched structure battery/SC HESSs V SC.min should be limited to V B to obtain the same range of the DC‐bus voltage changing as in the proposed HESS configuration. Equating the right parts of Equation () for the compared variants, we obtain the following expression of the ratio of SC bank capacitances for the proposed HESS configuration С SC.proposed and other switched structure battery/SC HESSs С SC.other :

\frac{C_{SC.proposed}}{C_{SC.other}} = \frac{1 - {(V_{B} / V_{SC.max})}^{2}}{1 - 0 . 5^{2}}

“…Therefore, to combine the SC bank with battery in HESS design, power semiconductor DC–DC converters are used, which work as electronic transformers of direct voltage. Currently, a number of battery/SC HESSs configurations have been proposed and investigated, among which a passive, a fully active, and a semi‐active configuration belong to the classic ones [9–12].…”

Among new configurations of battery/supercapacitor (SC) hybrid energy storage systems (HESSs) for electric vehicles (EVs), several can be united under the common name of ‘switched structure’. Their features are the ability to switch their structure during operation to direct power of a DC‐bus from the battery or from the SC bank, as well as the use of a low‐power DC–DC converter that connects both ESSs. Here, such a switched structure between battery/SC HESS was improved, which made it possible to obtain new operating modes. They expand the operating range of the SC bank, while the DC‐bus voltage range remains relatively small. As a result, the installed capacity of the SC bank can be reduced by 50% without decreasing the available energy of the SC bank. An algorithm for the energy management system was developed according to the rule‐based strategy that allows to choose one from the eight operating modes. The simulation of investigated EV operation with the proposed HESS was carried out during the transport cycle on a model developed through the energetic macroscopic representation approach. The simulation results are confirmed by experiments on a scaled‐down experimental setup.

“…Finally, one better controller is suggested based on the losses present in the two configurations used for the final model representation in real-time implementation. In this work, the authors mainly concentrated on developing various HESS with common control structures for proper load between two energy sources [16]. An ANNbased MPPT is adopted to attain the maximum power from the PV system.…”

Many pollution-related issues are raising due to the usage of conventional internal combustion engines (ICEs) vehicles. Electric Vehicles/ Hybrid electric vehicles (EVs/HEVs) are the finest solutions to overcome those problems associated with ICE-based vehicles. The EVs are introduced with a signal energy source (SES), which is not a successful attempt, especially during transient vehicles, driving, etc. Multiple energy sources (MES) EVs are introduced to attain better performance than the SES vehicles, which is obtained by combining two sources like battery/fuel cells, ultracapacitor. In this contest, energy management (EMNG) plays a vital role in sharing the load to the sources as per the EVs requirement. In the case of MES-based EVs, the controller always plays a significant role in the related EMNG system because it is the key factor in improving vehicle efficiency. In this article, a study has mainly been done related to several conventional, intelligent controllers and control algorithms to do the proper EMNG between sources present in the EV.

“…FLC does not rely on precise mathematical models but on the knowledge and experience of experts. In [11][12][13], low pass filtering (LPF) was used to separate the high-frequency and low-frequency parts from the energy consumption curve of the vehicle's operating conditions and the HESS was controlled and optimized by the battery and ultracapacitor outputs, respectively. In addition, rule-based controllers also include load tracking control and threshold strategy.…”

Compared with batteries, ultracapacitors have higher specific power and longer cycle life. They can act as power buffers to absorb peak power during charging and discharging, playing a role in peak shaving and valley filling, thereby extending the cycle life of the battery. In this article, a replaceable battery electric coupe SUV equipped with a lithium iron phosphate (LiFePO4) power battery is taken as the research object, and a vehicle dynamics simulation model is established on the MATLAB/Simulink platform. Parameter matching and control optimization for a hybrid energy storage system (HESS) are conducted. Through a proven semiempirical cycle model of the LiFePO4 power battery, the operating cycle life model is derived and used to estimate the battery cycle life. World Light Vehicle Test Cycle (WLTC) simulation results show that the HESS with 308 ultracapacitors can extend the cycle life of the LiFePO4 power battery by 34.24%, thus significantly reducing the operation cost of the battery replacement station.
