Week-6 Challenge: EV Drivetrain

Objective of Main Project: Developing Adaptive Cruise Control feature as per the Requirement Document using MATLAB Simulink. Follow all the MBD related processes: Requirement Tagging & Traceability, SLDD creation, Configuration Parameter changes, Model Advisor check & Code Generation. In Configuration Parameters:…

Aim: Determining the direction of vehicle moving, while following MAAB guidlines. Firstly we have to create sldd file, and add signals and its parameters and save the file. Now converting documented requirement into model.Whenever there is a requirement it has to be in a subsystem. Here we take 2 subsystem, namely Requirement_1,…

Nanophosphate lithium iron phosphate (LiFePO4) battery technology delivers high power and energy density combined with excellent safety performance and extensive life cycling in a lighter weight, more compact package (Cell: ANR26650M1-B), these cells have low capacity loss and impedance growth over time as well as high…

1. 3 test cases of BMS close loop Test Harness model Case 1- Now click on the Test Sequence Varient Subsystem and choose the Test case as 1 Give RUN command, By selecting test case as 1, open BMS_State Request in that we see, BMS_TestSequence we found out that 1st case is selected. Here we observe all green signals means…

Objectives:         1. System level configurations        2. Model parameters        Block Diagram of the system:  Vehicle body subsystem: It consists of Tires , simple gear and vehicle body which deals with gradient, body mass, aerodynamic drag, road…

1. Material used and chemical reaction occuring at anode and cathode: Chemical reactions in batteries:   2. Various types of Lithium-ion Batteries Ref: BU-205: Types of Lithium-ion - Battery University  

6. The forces acting on the airplane & towing vehicle Analysed  The forces mainly associated with the moving of airplane with help of tow vehicle are Rolling Resistance force and Aerodynamic Drag force. 1) Rolling Resistance Force: This force is experience by the tyre of vehicle when it's moving on any surface.…

1. FTP75 drive cycle: Work done =K.E =0.5*m*v^2 m=mass of vehicle =1000kg v= velocity of vehicle =Vf (100)- Vi (0)        (vehicle decelarating from 100-0) t=10 sec Power required is P=E/t P=(0.5*1000*(100*0.278)^2)/(10) =38.36kw Energy required for braking from 100-0 speed in 10 sec E=0.0106 Kwhr Energy…

1.  Speed control is basically 2 quadrant operation, in which use of H bridge to generate chopped voltage and to control the speed. There are switched and 4 diodes and the mototr is kept between this switches. At a time 1 switch from 1 leg is operate so first Q1 and Q4 conduct & then Q2 & Q3 conduct. From…

1. Types of Power Converter circuits in EV & HEV  DC - DC Converters Convert unregulated DC i/p into regulated DC o/p. Non Isolated Converters- Connected directly to each other via electrical wire or bus. Ex.- BUCK, BOOST, BUCK-BOOST. Isolated Converters- Components of i/p & o/p not connected directly…

1. cargo mass is 500 kg  Result: The vehicle cannot travel for 45 km with FTP drive cycle as it only manages toncover 17.8km. 2. changing the battery capacity to 30 and no of cycle to 4 Graph obtained: When the battery cycle was increased it was not  going to cover 45 km after increasing battery capacity…

1. the difference between mapped and dynamic model of engine can be expressed from the chart below:- 2. EV reference model 2. Mode calculate miles per gallon by taking vehicle speed parameter as input and multiplying and taking root value so we get the positive values further integrating it and sending the collected…

 OBJECTIVE : To carry out a system-level simulation of an all-terrain vehicle.  An all-terrain vehicle (ATV) is defined as a motorized off-highway vehicle designed to travel on four low-pressure or non-pneumatic tires, having a seat designed to be straddled by the operator and handlebars for steering…

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 rinsing…

1. Simulink model of Doorbell using Solenoid Block . Solenoid- A solenoid is an actuator assembly with a sliding ferromagnetic plunger inside the coil. Without power, the plunger extends for part of its length outside the coil; applying power pulls the plunger into the coil. Electromagnets with fixed cores are…
