THE EXPERIMENTAL POWER MANAGEMENT CONTROLLER IN PHEV

The purpose of the power management controller subsystem in the Parallel Hybrid Electric Vehicle (PHEV) is to optimally arrange the engine and electric motor for load sharing providing the desired vehicle power while increasing the overall efficiency. This work adopts a PMSM as an electric drive for the HEV system. An experimental electric driving system is implemented in the Laboratory. The Borland C Language was used to implement the control algorithm during experimental work. The algorithm was executed via a data acquisition card. The experimental work in this paper handles the power management controller and torque sharing between the electric driving system and the Internal Combustion Engine (ICE) driving system. The experimental results showing the Direct Torque Control (DTC) behavior of the adopted PMSM and the experimental results at different loading and speed conditions are recorded.
