Part A: 1. Search and list out the total weight of various types of aircrafts.  ANSWER: AIRCRAFTS  : An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of…

For a defined driving cycle Answer:  The special feature of electric vehicles and hybrid vehicles is their ability to absorb, store and reuse the braking energy. A successfully designed braking system for a vehicle must always meet two distinct demands. While applying the sudden brake, the vehicle must come to rest…

1. A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. 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), a forward voltage Vf is developed between…

1.  Which types of power converter circuits are employed in electric and hybrid electric vehicle? Power Converter:Power converters are components needed for converting the AC power from the grid into something that can be used for the storage process, and vice versa. This can be, for instance, mechanical power…

  Q.1: WHAT IS THE DIFFERENCE BETWEEN MAPPED AND DYNAMIC MODELS OF ENGINE, MOTOR, AND GENERATOR. HOW CAN YOU CHANGE THE MODEL TYPE. Difference between mapped and dynamic models Engine, Motor, and Generator. features MAPPED In the mapped model is the data used for the operation and simulation are to be entered…

  Use the ADVISOR tool and simulation the following: Q.1: For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle. Conclude your observations. Answer:1 Now open the ADVISOR Tool, set the load file to 'EV_defaults_in'   components to motor_controller.…

Obtain the transfer function of a mass spring damper system and use it in the model. Add a PID controller to adjust the force on mass so that its position follows a reference signal. Answer: How to implement the equations of mass-spring-damper in Matlab Simulink? Answer:   The equation shown below is implemented in…
