1. Design a battery pack for a car roughly 150 Kw with 120 V. Use 3500 mAh 3.6V nominal NMC chemistry cell. a. Design the battery pack configuration.  Ans. Given, Battery Pack Power = 150 kW Pack Voltage = 120 V Cell Capacity = 3500 mAh Voltage = 3.6 V So now as we know, P = V*I I = P/V I = 150kW/120 V = 1250 A If the…

To Create a detailed MATLAB model of an Electric Rickshaw (three-wheel passenger vehicle). Objectives: Rear wheels are driven by PM brushed-type motor Assume the efficiency points of the motor controller and motor Make an excel sheet of all input and assumed data  Results: For any three standard driving cycles show…

Introduction -  Electric vehicles (EVs) are automobiles that use electrical energy to operate. A motor/generator, motor controller, power converters, wheels, and batteries make up an EV's basic structural elements. The power is necessary for the wheels to move and produce traction is provided by the electric motor.…

Why Electric Vehicle? Electric Vehicle (EVs) is the future of the automobile industry. This requires a highly accurate and efficient model that would run on clean and green energy. For now, the energy we use to recharge EVs mainly comes from non-renewable sources, but this would also shift to renewable sources. If…

PART-A 1) Search and list out the total weight of various types of aircraft.  Ans: To understand the different types of aircraft and the total or Gross weight of the aircraft, we need to understand the meaning and how the weight is measured or considered for an aircraft. The term used for the total weight of…

1) Braking: Braking is the process of slowing down or stopping a moving vehicle when necessary. Brakes can be applied using a variety of mechanical or electrical means. The method that uses friction is the most popular. It consumes energy. Consumed kinetic Energy can be derived as following equation where braking energy…

1) A) When we talk about Speed control of DC motors using H-Bridge. As we can see the circuit and terminal explanation of the DC motor. As seen in the circuit there are 4 switches SW1, SW2, SW3, and SW4. When the switches are turned on in a synchronized pattern, such as SW1 and SW4 are closed at the same time would make…

1)  The components used in EV and HEV can be understood by the layout shown below,   In the figure shown above, there are different components including a Fuel tank, Engine (in the case of Hybrid), Battery pack, Power Electronic converter, Traction motor, and Transmission.  The Power electronic converter…

1) Mapped models: Mapped models are those type of models that comes into use when the behavior of a certain type of model is not of our interest or is not required to redesign and can be modeled with predefined values in the form of lookup tables. The Mapped Models such as motor, engine and generator give us an ease to…

 (1) In the below screenshot the vehicle selected is EV_defaults_in. The Cargo load is entered as 500 kg and the rest specifications used are default data. In the Drive cycle, the type used is FTP as mentioned in the question. Number of Cycles = 5. And the Time step = 1.   As shown in the statistics that has…
