EV Drive System Emulator
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryIn this Project, our main concern is to promote green technology and electric bike industry in Pakistan .Objective of our project is to develop electric bike drive system emulator and test bench unit for analysis of electric bikes.Emulator will validate hardware real-time performance of electric bikes digitally on HMI. The results will be helpful for design commercial electrical vehicles in terms of motor requirement, storage charge/discharge analysis, machine behavior at different speed and torque, braking system, charging battery while driving and their limitations.This project will reduce the fuel consumption and will be in economical approach for local use. In this project we will implement the digital security system by using touch LCD(HMI). We are also introducing regenerative breaking system in our emulator which will help to find out that how much power is regenerating from the specific motor to charge the battery and this power will be shown on HMI screen.
Project Objectives- Energy Efficient and green technology.
- Electric bike test bench
- Real time analysis of Electrical Bike Parameters
- Regenarative Braking
- Environmental friendly
- Economical Transportation
An emulator is a flexible power electronics system. which allows simulating the behavior of Electric Vehicle while it is in working.
BLDC Motor is controlled by power electronic conveter. Sensors are monitoring real time values which are integrating with controller and using HMI based GUI ( Graphical User Interface) and all the parameters values will be digitally shown on HMI. In this project we have implemented the digital security.Regenerative braking is a process of harnessing the stored kinetic energy in the form of electric energy during the brake period, where the motor of the vehicle operates as a generator and charges the battery. Necessary units such as PWM circuit, controller, gate driver circuits are implemented to develop EV emulator. The back emf at different speed is recorded to select the proper charging system. After that, using the proposed method the battery is charged and successful outcome is seen. Furthermore, back emf performances with varying duty cycles are noted. Based on the gathered data the energy regeneration is calculated for several speeds. Overall, the proposed system can explore the commercial sectors of the recent electric bikes and effectively store the braking energy in the form of battery charging.
