Week-3 Challenge: ADVISOR Tool
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. Sol: For this case the EV_defaullts_in file was chosen and only the cargo mass was changed to 500 kgs and remaining parameters were kept as…

Week-4 Challenge WOT Condition Part-2
1. What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type? Sol: Mapped Model: This type of model runs based on the look up tables or some predefined input values.Hence these models are not as efficient in output when compared to dynamic motor models. Although…

Week-6 Challenge: EV Drivetrain
1.Which types of power converter circuits are employed in electric and hybrid electric vehicle? Sol: AC to DC Converters (Rectifiers): An AC to DC converter or rectifier can convert AC voltage to DC voltage. Rectifiers periodically reverses directionof AC to DC (which flows in only one direction). The reverse operation…

Week-7 Challenge: DC Motor Control
1. Run MATLAB demo ‘Speed control of a DC motor using BJT H-bridge’. Modify the model such that armature current doesn’t shoot up when motor changes direction from forward to reverse. Sol: The following image shows the Simulink model: i) At 75% duty cycle: Here the motor starts in the positive direction with a duty cycle…

Week-11 Challenge: Braking
1. For a defined driving cycle, calculate the energy required for braking. Sol: The drive Cycle considered is attached in the attachments & is as follows: The time period of the drive cycle is from 0 to 60 seconds. The MATLAB script is as follows and also has been attached in the attachments. PLOT: So for the given…
