Mathematical Modeling and Simulation of Equivalent Circuit Modeling for Electric Vehicle

Abstract

Three different forms of electric vehicle modeling—Multi Scale Multi- Dimensional, Newman Tiedemann Gu and Kim, and Equivalent Circuit Model—are compared in this essay. Both battery packs and single cells can be modelled using this method. Li-ion battery. ECM was discovered to be a trustworthy solution for modelling electric vehicles. In an equivalent circuit concept, an electric circuit represents how a battery behaves. It uses an electric circuit made up of a resistor, capacitor, and OCV to mimic the behavior of a battery. The lifespan and dissipation of electric batteries are of primary interest. In battery modelling, maximum battery life and low power dissipation are crucial. Maximum battery life and low power dissipation are crucial for portable devices. Whenever engineers have reliable and efficient battery and circuit models at their disposal, they can anticipate and optimize battery endurance and performance in the circuit. As a result, the project's suggested idea is to assess performance metrics utilizing a 2RC circuit for an electric car battery, particularly a Li-ion battery. The effort will begin with MATLAB Simulink-based statistical modelling of the ECM along with examination of its implementation.
