Week-6 Challenge: EV Drivetrain

Q1. https://docs.google.com/spreadsheets/d/1SGVIUIMjdVOU8oh-lK4WOZM6YrQ9aIovVqChmu6zL6E/edit?usp=sharing Q2.  there are two different types of speed when talking about airplanes – ground speed and airspeed. While ground speed is the airplane’s speed relative to the surface of the Earth, airspeed –…

Q1. Cycle used is WorldWide harmonized light vehicle test.  https://docs.google.com/spreadsheets/d/15GQ6E61ClZdhwamQWd0exKsb7dlC-KuHxsLW1yuR5ss/edit?usp=sharing Q2. Electric motor can't develop braking torque at high speed similar to starting, because Braking torque is applied in the opposite direction of the rotation.…

1) 1.1 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 collector and emitter (in the range of 1 V). Therefore, the IGBT block can be used to model the BJT device.…

AC-DC Converters A single-phase converter with two natural commutated thyristor is shown Average value of the output voltage can be controlled by varying the conduction time of thyristors This converters are also known as controlled rectifiers AC-AC Converters Used to obtain variable AC output voltage…

1.1) What is the difference between mapped and dynamic model of engine, motor and generator?    1. Mapped Model uses a set of steady-state lookup tables to characterize engine performance. The tables provide overall engine characteristics, including actual torque, fuel flow rate, BSFC, and engine-out exhaust…

q1. maximum distance ev_default can travel with 500 cargo weight is 41.4 km maximum distance ev_default can travel with default cargo weight is 48.2 km this is due to increase in the total weight of vehicle resulting in increase in tractice force.   q2. here cargo weight is 500kg Default no of battery module are 25…

AIM:  Write a function that extracts the 14 co-efficients and calculates the enthalpy, entropy and specific heats for all the species in the data file. The formulae are shown below.  Here R is the universal gas constant, T is the temeprature   1. function for calculating specific heat,entropy,enthalpy:-…

Aim: Try to understand the concept of genetic algorithm by referring to varius sources before you attend this challenge. Look out for information regarding stalagmite function and ways to optimise it. Write a code in MATLAB to optimise the stalagmite function and find the global maxima of the function. Clearly…

  AIM :  Your objective is to write a program that solves the following ODE. This ODE represents the equation of motion of a simple pendulum with damping %inputs l = 1 %meter m = 1 %kg b = 0.05 %damping coefficient g = 9.81 %m/s2 %initial conditions theta_0 = [0;3]; %time points t_span = linspace(0,20,500); %solve…

Q1. AIM: Implement control logic of a “washing machine” using Stateflow as per given sequence:  If the power supply is available, the system gets activated,If the Water supply is not available, stop the process & indicate through LED Soaking time should be 200s followed by Washing time of 100s.Then…
