Hybrid electric vehicles (HEVs) simulation using MATLA

Introduction—

MATLABSolutions demonstrate In this task we are going to design The search of greater fuel efficiency for ground vehicles has escalated in recent years as the price of fossil fuels has risen and environmental concerns have grown. Many automobile firms are enthusiastically developing hybrid electric vehicles (HEVs), which appear to be the most viable short-term answer. An HEV augments the standard powertrain with an electric power route, which helps to increase fuel efficiency through engine right-sizing, load levelling, and regenerative braking. we are modelling a series hybrid automobile using an electric motor to move the vehicle. The motor is driven by two mediums, the first being a battery and the second being an electric generator. Eliminating the negative environmental implications of vehicle traffic due to hazardous and greenhouse-gas emissions is one of the most pressing concerns in today's global society. As a result, different forms of vehicle emissions are legally regulated on a national and, in certain circumstances, regional level. Vehicle manufacturers are being forced to invest in various fuel-saving technologies in order to satisfy projected more stringent standards in the near future. Electric machines deliver torque more quickly than internal combustion engines, especially at low vehicle speeds. As a result, even with lower total rated power, launching performance can be enhanced.

Load levelling can also be accomplished by including an electrical route, which allows the engine to run more efficiently regardless of road load. When the vehicle is decelerating, regenerative braking allows the electric machine to absorb some of the vehicle's kinetic energy and recharge the battery. Simulink model system includes several subsystems, including motor drive, generator, battery, power train model, engine generator controller, and vehicle control unit development. The motor drive subsystem consists of a PMSM motor that powers the vehicle and is coupled to a power train model that includes a gear with a ratio of 6:1 that moves the vehicle's wheel. The motor drive is connected to the vehicle control unit, which controls the speed of the wheel; power is supplied by the battery module; when the battery is 20% depleted, the Generator starts the engine control unit, which controls the speed of the engine by using the throttle valve; vehicle charging will continue until the vehicle's battery is completely depleted .
