Question#1: Mapped models can be modeled with predefined values in the form of lookup tables and it runs faster than the dynamic model as it uses the values instead of components.  Dynamic Model represents the actual components instead of predefined values in the form of lookup tables. Mapped Model of Motor/Generator:…

Question#1: Types of power converter circuits are employed in electric and hybrid electric vehicle are as follows: Power converters is a very essential part for both Electric and Hybrid Electric Vehicle as the voltage level of the components like battery, fuel Cell and ultra capacitors should be matched with the voltage…

Question#1(a): The below example shows the simulation of an H-bridge used to generate a chopped voltage and to control the speed of a DC motor. Description: The Bipolar Junction Transistor (BJT) when used for power switching applications, operates as an IGBT. When it is conducting (BJT operating in the saturated region),…

Study#1: Braking: Braking is the one of the important requirement to retard the speed of the vehicle. Usually mechanical brakes are used to retard the vehicle speed by appling friction on the wheels. It absorbs either kinetic energy or potential energy or both while remaining in action and this absorbed energy appears…

Introduction: The major components of an electric vehicle system are the motor, controller, power supply, charger and drive train. Controller is the heart of an electric vehicle, and it is the key for the realisation of a high-performance electric vehicle with an optimal balance of maximum speed, acceleration performance,…

Study#1:a) To design the battery pack configuration, we first need to calculate the number of cells required to achieve a voltage of 120V and a capacity of 150kWh. Voltage per cell = 3.6V, Total voltage required = 120V, Number of cells in series = Total voltage required / Voltage per cell Number of cells in series = 120V…

Study#1.a): To calculate the heat generation in the battery pack, we need to first calculate the power dissipated by the battery pack. The power dissipated by the battery pack can be calculated using the following formula: Power Dissipation as heat= I^2 * R * t where, I is the battery current and R is the internal resistance…

Objective: The main goal is to develop a vehicle speed control system using a PI controller and generate brake and accelerator commands without using a ready-made driver block for speed control. The model should accurately simulate the vehicle dynamics, considering factors such as mass, rolling resistance, aerodynamic…
