Project Summary

Research project introduces efficient power-electronic converter circuit for Electric Vehicle drive system. Also, promote the environment-friendly EV technology industry in Pakistan. The main objective of our project is to design Six-Step DC/AC converter required to drive an electric vehicle BLDC motor. the project will analyze the real-time performance of the electric vehicle on HMI. This project reduces fuel consumption and will be economical for daily use. The project also adds a regenerative braking system in our power converter which will generate power while slows down a moving vehicle. The circuit will be designed using Proteus and MATLAB simulation software. The results will be helpful for design commercial electric vehicles in terms of motor requirement, storage charge/discharge analysis, machine behavior at a different speed and torque, braking system, charging the battery while driving, and their limitations.

• Cheap EV Transportation

Project Implementation Method

We are designing a controller-based power-electronic converter for an Electric Vehicle drive system.  Basically, a converter is a flexible power electronics system that generates the desired pulses to operate the BLDC machine. The converter will drive the BLDC motor and power will flow from the batteries to the motor following the particular switching. On the other hand, during the braking time power will flow from the motor to the battery side. This will allow charging and discharging of Battery. For the controlling of the motor, throttle and brake sensors will be used. In our controller, we will use Arduino to control our motor and other sensors that are connected to the motor. The regenerating system is a process of harnessing the stored kinetic energy in the form of electrical energy during the braking period. Where the motor of the vehicle operates as a generator and charges the battery. Necessary circuits such as controller, six-step converter system, gate driver circuits are implemented to develop EV drive system. The back emf at different speeds is recorded to select the proper charging system. After that using the proposed method the battery is charged and a successful outcome is seen. Furthermore, back emf performance with varying duty cycles is noted. Based on gather data the energy regeneration is calculated for different speeds. Overall, the proposed system can explore the commercial sectors of the recent electric vehicle technology.
