Thus a vehicle has to be monitored on regular intervals of time and hence their life and efficiency has to be increased. Automatic Stop - Start System is a new energy-saving product, which can obtain a good fuel economy and reduce emissions for the car. The work principle and mechanical structure are analyzed in this project. The key technologies of idle-stop-start system are analyzed based on this. Then the idle-stop-start system is modeled and analyzed. The project aims to develop an Automatic Stop – Start System for the Electric vehicle to save the energy consumed by the vehicle. This method helps in increasing the efficiency of the EV and the life of various components such as Batteries, Power electronic components increases. The project also aims to build a system which can monitor various parameters such as Voltage, Speed, Temperature, Battery charge level, etc of an Electric vehicle (EV). It helps in assisting the owner to frequently checking the status of the vehicle and maintaining the vehicle whenever there are changes in the operating conditions of the vehicle. This project presents an implementation of a Wireless Internet of Things (IoT) system applied to the traction motor drive condition monitoring in electric vehicles (EVs). The design and testing of the prototype using an RL78 microcontroller module to acquire battery’s voltage, current, and temperature information for the motor condition monitoring application is presented.

INTRODUCTION 1.1 Electric Vehicles: Plug-in electric vehicles (also known as Electric vehicles or EVs) are widely used for pollution free transportation. They can reduce emissions and even save you money. Fueling with electricity offers some advantages not available in conventional internal combustion engine vehicles. Because electric motors react quickly, EVs are very responsive and have very good torque. EVs are often more digitally connected than conventional vehicles, with many EV charging stations providing the option to control charging from a smart phone app. Since the electric grid is available almost anywhere, there are a variety of options for charging: at home, at work or on the road. By charging often, you may never need to go to a gas station again. But EVs provide more than just individual benefits. EVs can help India have a greater diversity of fuel choices available for transportation. India uses nearly five billion barrels of petroleum last year, two-thirds of which went towards transportation. Our reliance on petroleum makes us vulnerable to price spikes and supply disruptions. EVs help reduce this threat because almost all India electricity is produced from domestic sources, including coal, nuclear, natural gas, and renewable sources. EVs can also reduce the emissions that contribute to climate change and smog, improving public health and reducing ecological damage. Charging your EV on renewable energy such as solar or wind minimizes these emissions even more. 1.2 Vehicle Monitoring System: Traction motor drive system is an essential and critical component for an electric vehicle (EVs). The traction motor must be efficient and reliable as it is required to provide both speed and torque in wide operating range while maintaining precise control of the motor drive safely. To prevent the traction motor’s abnormalities, improved reliabilities and effective operation with an early warning with instant notification is desirable and motor’s vibration, current and temperature are practically three parameters that are well studied and widely accepted in detecting motor’s failures due to electrical and mechanical faults. According to the survey done by Institution of Electrical and Electronic Engineer (IEEE), 44% of motor’s faults are from bearing and 24% are from stator. The majority of mechanical failures in motor are mechanical imbalance, rolling and bearings because a continuous stress on them can result in the major failure. Factors such as improper lubrication, improper installation, contamination and corrosion often contributed into rolling and bearings faults. A vibration sensor and current sensor are able to detect motor’s rough running of bearing increasing vibration and unbalance shaft current due to the flux disturbance caused by rotor eccentricities. Bearing failure also causes temperature rise to exceed motor’s predetermined load temperature.
