Hybrid electric vehicle(HEV), Energy Management System (EMS), Pontryagin’s Minimum Principle (PMP), rule based and optimization based.

There is need of exploring the knowledge about energy management system which is used in HEV to enhance its performance and meet the demand of driver and vehicle also reduces pollution, fuel depletion and carbon emission. Also in order to provide better efficiency, power management system plays a important role in HEV operation. Several power management techniques are available for real time application and can provide better efficiency for different driving condition. Rule based methods and Optimization based methods focused here. In rule-based methods, methods are easily implemented and are very simple in real time but cannot provide best of optimality whereas in optimized based methods, it can provide better results but at high cost of high computational requirements and price. Thus, in this review- based paper we will brief about the latest trend of EMS and power system requirement that are based upon rule based and optimization based and will highlight on pros and cons.. Another method is Pontryagin's Minimum Principle (PMP) which research the intent of the driver and the operation state identification of HEV based on Markov theory, in full consideration of the people-vehicle-road influence on power management system and problem of optimum solution in power management in case of variation of real operating problem is eliminated.
