Ans.1- Given data, Required Power = 150 KW Required Voltage =  120 V. Batatry capacity = 3500 mAh or 3.5 Ah Battery Nominal Voltage =3.6V For finding the current we know that , Power(P) = Current(I) * Voltage(V) Current(I) = power(P) / Voltage(V)                  = (150 *1000) / 120 Current(I) = 1250 Amps a) Design the…

OBJECTIVES: Create a detailed MATLAB model of an electric rickshaw (three-wheel passenger vehicle) as per the details below:  Rear wheels driven by PM brushed type motor Assume efficiency points of motor controller and motor Make an excel sheet of all input and assumed data  Results: For any three standard driving…

Solution: The electric vehicle is a vehicle, which uses one or more electric motors for propulsion. Depending on the type of the vehicle motion may be provided by rotary motor or by a linear motor (in the tracked vehicle). The electricity stored in battery-powered by electric motor & battery can be charged by plugging…

Ans. An Electric Vehicle (EV) is a vehicle that uses one or more electric motors or traction motors for propulsion.  Components of an EV -  EVs have no need for the fuel engine and gear transmission, the two of the most crucial components for internal combustion vehicles. An electric powered car has three primary components…

Part A)1.- Aircraft Gross Weight:The aircraft gross weight is the total aircraft weight at any moment during the flight or ground operation.An aircraft's gross weight will decrease during a flight due to fuel and oil consumption. An aircraft's gross weight may also vary during a flight due to payload dropping . At the…

Ans.1 Here i used "New York Drive Cycle". Getting the Data from the EPA website and prepare a Excel data sheet. To calculate the energy required for braking, here we have 33 decelerations points were made during this driving cycle, So 33 braking energy is to be calculated and sum it up to get the Total braking energy.…

Ans.1- In the model named 'Speed control of DC motor using BJT H-bridge'. Four switches are used and for providing the gate pluse four pulses are given to them. Here H- bridge DC chopper circuit is designed to control the speed of the motor. IGBT acts as BJT in power switching devices. Four IGBT switches are used for inverting…

ANS.1-Power Converter circuit is a circuit which converts the one form of electric energy into other form of electric energy. It consists of power electronic switches, transformers, electric choke,resistors, capacitors, diodes.It can be classified into 4 categories: AC to DC: It is also called "Rectifier". It converts…

Ans-1.Mapped Model Mapped Model are data base modeling like it makes on the basis previous collected or estimated data. The engine or motor torque is sensed and the engine of motor block generates the required torque output just as defined in data witout realtime sensing. It is faster then Dynamic model as it is not real…

Ans.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. 1.Fristly Run the advisor in Matlab And Select the Metric for Calculation in kelometers(Km). 2.Then in ADVISOR Vehicle Input GUI selesct Load File "EV_defaults_in" from the drop…

 Solution: Driving cycles:- The term "driving cycle" refers to a test that measures vehicle speed over time. It is used to evaluate a car's fuel consumption and pollutants emissions in a standardized way to compare similar vehicles. The driving cycle is carried out on a chassis dynamometer, where tailpipes automobile emissions…

Solution: IN this model we use 10 series configuration of the lithium-ion battery pack. These are all battery cells connected in series. This battery pack charges or discharges by using the controlled current source and signal build in signal builder. For this cell enables the temperature effect and aging effect option…

Solution:  A step-down DC/DC converter is a device capable of converting an unregulated input voltage into an regulated output voltage lower than the input voltage.A buck converter steps down the applied DC input voltage level directly.  Given: Vin = 48V Vout = 12V Output Current = 10A **Inductor current ripple(dI/I0)…

ANS-So, for building the battery pack we need to do some calculations:Given Data: Vehicle Weight=300kgMotor Rating=1200wh.65VRange=225KmMax Speed=50 kmphLets calculate Motor CurrentPower = V*I1200 = 65*II = 1200/65I = 18.46 ACurrent withdrawn By Motor 18.46 AmpAssure Current Loss 1-10%After loss new motor current 18.46*1.05=19.38…

Ans- In pulse width modulation speed control the motor with a series of 'ON-OFF' pulses and varying the duty cycle, the fraction of time that the output voltage is 'ON' compared to when it is 'OFF', of the pulses while keeping the frequency constant.The power applied to the motor can be controlled by varying the width…

Ans: Defining the parameters of for DC motor Jb,Km,Kt,Ra,La Taking the Matrix A and F from Statespace model  A = -10.0000 1.0000-0.0200 -2.0000 F = 02 Desired poles of equation; Vs(s)= (Jla)*S^2+(JRa +BLa)*S +(BRa+KtKm)get roots of the equation and feed them in command Place(A,F,P) we get Kp as K(1) and Kd as K(2)…
