QUESTIONS For a defined driving cycle, calculate the energy required for braking. Why electric motor can’t develop braking torque at high speed similar to starting? How electric and mechanical brakes are coordinated?  Make a MATLAB program which plots contour of given motor speed, torque and efficiency values.…

ANS 1: THEORY - Pulse Width Modulation (PWM) A far better method of controlling DC motors is to use pulse width modulation or PWM. With PWM the motor is sent a series of pulses. Each pulse is of the full voltage that the motor can handle so a 6-volt motor will be sent 6-volt pulses while a 12-volt motor will be sent 12…

AIM: Which types of power converter circuits are employed in electric and hybrid electric vehicle? To calculate the steady state speed of the EV if the duty cycle is 70%. Author’s perspective on Induction vs Dc brushless motors. ANS 1 TYPES OF POWER CONVERTER CIRCUITS EMPLOYED IN ELECTRIC AND HYBRID VEHICLE The types…

ANS 1: Mapped Model: Model uses a set of steady-state lookup tables to characterize engine performance. The mapped model is one type where the data is defined in lookup tables by default and are provided to the model beforehand. This type of model requires data to be given to all systems previously by the user and cannot…

AIM: using the ADVISOR tool analyse the following To determine whether the vehicle subjected to FTP driving cycle will be able to travel 45km if the cargo mass is increased to 500kg with other parameters remaining the same. Perform the same simulation with the change of battery capacity. To perform a gradeability test…
