1.  For EV_defaults_in file with cargo mass of 500 kg: The mass of the vehicle is changed to 500kg. The simulated drive cycle under cyc_UDDS output for 1 cycle is shown below. The simulated drive cycle under cyc_FTP output for 1 cycle is shown below. With 1 cycle, the distance covered by the EV is 17.8km. With…

 1. (a)Difference between mapped and dynamic model of engine, motor and generator. Mapped Model: Mapped model is also called as Static model. The mapped model is preferred when the behaviour of the component model is not required. It is modelled with the predefined datasets in the form of lookup table to perform faster…

1. Types of power converter circuits employed in electric and hybrid electric vehicle: The power electronic converters are the key elements to interface energy sources to the drivetrain of the EVs in electric and hybrid electric vehicle. Advanced DC/DC and DC/AC converters are the type of power converter circuits…

1. A. Speed control of a DC motor using BJT H-bridge To create a chopping voltage and regulate the speed of a DC motor, an H-bridge simulation is employed. There are four BJT/Diode pairings in the H-bridge (BJT simulated by IGBT models). The simultaneous switching of Q1 and Q4 or Q2 and Q3 involves two transistors. When…

1. Energy required for braking: Indian drive cycle is created in excel using time(s) and speed(m/s) datas. The braking energy is calculated using, Braking energy=1/2*m*(vi-vf)^2 where, m-mass of the vehicle vi-initial velocity vf-final velocity The mass of the vehicle is assumed as 1000kg. Braking energy Calculation is…

Part-A 1. The aircraft gross weight  is the total aircraft weight at any moment during the flight or ground operation. For each flight, different weights are taken into account for several reasons. Manufacturer's empty weight (MEW)It is the weight of the aircraft "as built" and includes the…

Electric vehicles are expected to become the next disruptive force in technology and transportation. They have the power to completely alter the ways in which energy is produced, used, and directed. The negative environmental effects of conventional cars can be mitigated in part by using electric vehicles. However, they…
