“…In fact, such conversion structure (power electronics switches) could be reused with minor changes to match together modules with different degradation levels and then exploiting them according to their SOH. Finally, it is a current trend to look into hybrid energy storage systems for grid applications to reduce the oversizing of the storage systems and extend the lifetime of such battery systems [64], [65]. In this outlook, the SEABAT structure would be immediately ready and reusable in such systems, easily integrating arbitrary battery or storage technologies in the same system.…”

“…Both in the form of bulk energy storage and as a distributed transient energy buffer, energy storage systems play a significant role in a wide variety of industrial applications. [ 5 ] Some of the most important factors to think about when selecting a source of energy storage are its specific energy, power rating, longevity, dependability, and safety. Because of their high density and good cycle life, rechargeable batteries, particularly lithium‐ion batteries, are presently a popular alternative.…”

The primary goal of this study is to synthesize a high‐conducting polymer electrolyte film. The PVDF‐HFP and NaSCN film are prepared which showed the highest conductivity at 30 wt% dopant of NaSCN in the Polymer PVDF‐HFP which is 1.24× 10−4 S cm−1. Therefore, here the base polymer is taken as PVDF‐HFP and NaSCN (30 wt%) and further Acetylene Black is added to check the variation in the conductivity of the polymer film. Solution casting technique is used to create solid polymer electrolyte films using poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) with salt sodium thiocyanate and Acetylene Black. Polarized optical microscopy (POM) is used to evaluate the morphology of the polymer film surface. Fourier transform infrared spectroscopy (FTIR) to check the presence of functional group is used, impedance spectroscopy is used for the measurement of the conductivity of the sample, linear sweep voltammetry for finding electrical stability window, and transference number measurements for concentration of charge carriers are done for the electrical studies of polymeric films. The 1 wt% Acetylene Black doped polymer electrolyte film is found to have the maximum ionic conductivity, which is 1.95 × 10−3 S cm−1. The solid polymer electrolyte film has an electrochemical stability window (ESW) of 4.8 V and tion value of 0.83.

“…Rule-based strategies are normally designed using engineering hunches and experience to perform power allocation by following a map or set of rules [19]. Optimal strategies, derived from the optimal control theory, always involve minimizing some cost function, and then using mathematical optimization means, such as the Pontryagin minimum principle, dynamic programming, and nonlinear programming [20,21]. Optimal strategies were usually used to diminish hydrogen fuel consumption, and to increase FC lifetime and driving range.…”

Facing the challenge that the single-motor electric drive powertrain cannot meet the continuous uphill requirements in the cold mountainous area of the 2022 Beijing Winter Olympics, the manuscript adopted a dual-motor coupling technology. Then, according to the operating characteristics and performance indicators of the fuel cell (FC)–traction battery hybrid power system, the structure design and parameter matching of the vehicle power system architecture were carried out to improve the vehicle’s dynamic performance. Furthermore, considering the extremely cold conditions in the Winter Olympics competition area and the poor low-temperature tolerance of core components of fuel cell electric vehicles (FCEV) under extremely cold conditions, such as the reduced capacity and service life of traction batteries caused by the rapid deterioration of charging and discharging characteristics, the manuscript proposed a fuzzy logic control-based energy management strategy (EMS) optimization method for the proton exchange membrane fuel cell (PEMFC), to reduce the power fluctuation, hydrogen consumption and battery charging/discharging times, and at the same time, to ensure the hybrid power system meets the varying demand under different conditions. In addition, the performance of the proposed approach was investigated and validated in an intercity coach in real-world driving conditions. The experimental results show that the proposed powertrain with an optimal control strategy successfully alleviated the fluctuation of vehicle power demand, reduced the battery charging/discharging times of traction battery, and improved the energy efficiency by 20.7%. The research results of this manuscript are of great significance for the future promotion and application of fuel cell electric coaches in all climate environments, especially in an extremely cold mountain area.
