System Integration and Evaluation of Motor Drive, Energy and Battery Management System in A Hybrid Electric Vehicle

In the collective effort of reducing the world’s dependency on fossil fuels, the hybrid car technology is implemented. A typical hybrid vehicle combines the engine of a conventional car with an electric motor-generator. Recent enhancements allows a retrofit version of a hybrid car which enables a conventional car to be transformed into a Hybrid Electric Vehicle (HEV) with a few minor changes to the original structure of the car via the In-Wheel Motors (IWM).The three major components of a HEV includes the Motor Controller, Energy Management System (EMS) Controller and Battery Management System (BMS). It is of the utmost importance that these three components are well integrated in the retrofit HEV to ensure an efficient and smooth operation, enabling it to achieve its ultimate objective that is to reduce fuel emission. This paper includes the study of various signals of the HEV sub-systems, Motor Drive assembly and Graphical Driver Interface (GDI) configuration.
