Abstract
Choice of hybrid electric vehicles (HEVs) in transportation systems is becoming more prominent for optimized energy consumption. HEVs are attaining tremendous appreciation due to their eco-friendly performance and assistance in smart grid notion. The variation of energy storage systems in HEV (such as batteries, supercapacitors or ultracapacitors, fuel cells, and so on) with numerous control strategies create variation in HEV types. Therefore, choosing an appropriate control strategy for HEV applications becomes complicated. This paper reflects a comprehensive review of the imperative information of energy storage systems related to HEVs and procurable optimization topologies based on various control strategies and vehicle technologies. The research work classifies different control strategies considering four configurations: fuel cell-battery, battery-ultracapacitor, fuel cell-ultracapacitor, and battery-fuel cell- ultracapacitor. Relative analysis among different control techniques is carried out based on the control aspects and operating conditions to illustrate these techniques’ pros and cons. A parametric comparison and a cross-comparison are provided for different hybrid configurations to present a comparative study based on dynamic performance, battery lifetime, energy efficiency, fuel consumption, emission, robustness, and so on. The study also analyzes the experimental platform, the amelioration of driving cycles, mathematical models of each control technique to demonstrate the reliability in practical applications. The presented recapitulation is believed to be a reliable base for the researchers, policymakers, and influencers who continuously develop HEVs with energy-efficient control strategies.

Summary
The world is moving towards an era full of facilities updated with more recent inventions; pollutions are rising simultaneously where constant harm is evident to all living beings. An energy management strategy for battery-FC-UC-based hybrid source vehicles is proposed in [26] that considers power capability as significant parameters for battery and UC and utilizes finite state machines. For ensuring the convenience of getting into the appropriate way to control different HEVs individually, this paper upholds a detailed review of different existing control strategies for optimized performance with suitable vehicle topologies based on different ESSs with merits–demerits, simulation, and experimentation capabilities. A comprehensive analysis of key parameters, driving cycles, simulation platform, mathematical equations, and research work location is presented so that the researchers in this field can grasp the insights of HEV and its numerous control strategies.
