Objective1: For a defined driving cycle, calculate the energy required for braking. Answer: For a defined drive cycle for 600sec, the braking energy is calculated as below. Braking energy is given as: Total braking energy= 500{(44.5^2-12.0^2)+(39.0^2-0.0^2)+(29.8^2-12.0^2)+(38.0^2-12.0^2)+(56.5^2-14.5^2)+(46.0^2-20.2^2)+(49.8^2-14.3^2)+(28.2^2-0.0^2)+(25.6^2-13.9^2)+(19.1^2-16.2^2)+(33.5^2-0.0^2)+(21.9^2-0.0^2)+(24.5^2-13.1^2)+(17.0^2-0.0^2)}*(1000/3600)^2…

Objective1 Difference between mapped and dynamic model of engine, motor and generator. How can you change model type? (A) Mapped model: (1) Data driven model generally by lookup table (2) Static model (3) Preferred for system level Simulation (4) Represents Macro behavior (5) Takes less simulation time Dynamic model: (1)…

Objective1: Speed control of a DC motor using BJT H-bridge. Answer: (a) In order to control the speed of DC motor, voltage fed to the armature of it needs to be controlled. A chopper can be used to control the voltage fed to armature of DC motor by controlling the switching frequency of the chopper switch. There different…

Q1. Which types of power converter circuits are employed in electric and hybrid electric vehicle? Answer: Types of converter used 1) AC to DC converter or Rectifier: For charging battery an AC-DC converter is required to convert the AC supply to DC, which is also known as Rectifier. 2) DC-AC converter or Inverter: If the…

Objective1: To check for EV_defaults_in file, for cargo mass of 500 kg with all other default conditions, whether the vehicle can travel for 45 km with FTP drive cycle? Answer: The advisor tool GUI can be opened by typing >>advisor command in the command window, after which a GUI opens up. The vehicle type is the…

Objective: To carry out a system-level simulation of an all-terrain vehicle and to make a technical report explaining model properties and discussion on results. Theory: All-terrain vehicle (ATV): An all-terrain vehicle (ATV) is defined as a motorized off-highway vehicle designed to travel on four low-pressure or non-pneumatic…

Objective1: To implement control logic of washing machine using state flow for following conditions: Activate the system when power supply is available If water is not available, stop the process and indicate through a LED Soaking time of 200s followed by washing time of 100s, after that rising for next 20s and drying…

Objective1: To develop Simulink model of Doorbell using a solenoid with the switch is closed for 2 seconds and then released. Theory: Conventional doorbell uses a special type of electromagnet called Solenoid. In which there is a coiled wire surrounds a magnetic material called plunger. When current passes through the…
