A MECHANICAL PERFORMANCE STUDY AND SIMULATION OF A HYBRID ELECTRIC VEHICLE POWERED BY Ni-MH BATTERY

Cars are used in daily life in today's society, but noise pollution, greenhouse gas emissions and increased fuel consumption are constantly increasing. Hybrid electric vehicles are recommended to reduce fossil fuel resources and climate change affecting the planet. Hybrid electric vehicles have a low storage capacity, which is one of the most important parameters for the acceptability of HEV. This article aims to simulate the mechanical performance of a Ni-MH-powered hybrid electric vehicle in Matlab environment. The study focuses on Ni-MH battery controlled by DC-DC converter power supply for HEV. Performance of the proposed strategy controller provides adequate simulation results. The proposed control law increases the autonomy of the HEV utility under several speed variations. In addition, future industrial vehicles must take into account the choice of battery material during design stages. Battery model selection is important, and with the increasing emphasis on vehicle range and performance, Ni-MH battery can provide a viable alternative, as reported in this study.
