Hybrid Electric Vehicle (HEV) is one of the emerging environment-friendly technologies in vehicular world with improved efficiency but its main issue has been its energy management and supervisory control that ensures best energy distribution. This research analyzes the drive performances of different possible regeneration paths with standard drive cycles through hybrid powertrain model based on quasi-state model of machines. Further, the efficiency map table developed from laboratory test is utilized to estimate efficiency and energy loss in the motor. In this research, 65 kW generator and 110 kW motor of 3000 rpm with an efficiency map are utilized to develop a model in MATLAB. From the simulation result, it has been observed that fuel economy and final state of charge (SOC) of the battery improves when regeneration is done by both machines. The implementation of Rule-Based algorithm indicates that the battery charges only when Internal Combustion Engine (ICE) operates.
