Abstract:
This study focuses on the critical interplay between batteries and motors in Electric Vehicles (EVs), emphasizing how operational conditions, such as temperature rise due to current flow during discharging, affect battery performance and longevity. In EVs, the battery not only powers the motor through a discharging process but is also recharged using a generator, making its efficient operation essential. The research outlines three key battery-related processes: charging, discharging, and motor-assisted discharging, with particular attention given to the latter. Using MATLAB Simscape blocks, the study simulates and analyzes key parameters such as voltage, current, temperature, State of Charge (SOC), and motor RPM to understand the battery’s behavior under varying load conditions. The primary objective is to enhance battery life by implementing a Battery Management System (BMS) that uses real-time thresholds of temperature, voltage, and current to ensure safe and optimal operation. By closely examining these factors, the project aims to improve battery efficiency, prevent degradation, and ensure long-term reliability across diverse operational environments in electric vehicle systems.
Aim:
The aim of this project is to model, analyze, and enhance the performance and longevity of batteries in Electric Vehicles (EVs) by simulating charging, discharging, and motor-assisted discharging processes using MATLAB Simscape, and by implementing a Battery Management System (BMS) that ensures safe operation through real-time monitoring of key parameters such as temperature, voltage, and current.
Objective:
The objective of this project is to simulate and analyze the interaction between batteries and motors in Electric Vehicles (EVs) using MATLAB Simscape, focusing on three main processes: charging, discharging, and motor-assisted discharging. Key operational parameters such as voltage, current, temperature, State of Charge (SOC), and motor RPM will be monitored to understand their impact on battery performance. Additionally, the project aims to implement a Battery Management System (BMS) that uses real-time thresholds for temperature, voltage, and current to enhance battery safety, optimize performance, and extend battery life under varying operational conditions.
