Project Statement
It is required to reach 2018 design a small size electric vehicle to be used for the transportation of a small size family. The electric vehicle uses a DC motor power directly by a battery system. The vehicle is supposed to reach a speed of speed of 80 Km/hour. The battery system bank supplies 120 V. It is supposed to energize the motor for 160 Km before being recharged. Give the size of the battery required in AH (Ampere Hour). Estimate all the design characteristics of the car (car dimension, motor type, batteries type, connection and AH rating and over all car weight efficiency). Give all assumptions taken with justification and references.

A lightweight electric car is powered by a series combination of ten 12.0-V batteries, each having negligible internal resistance. Each battery can deliver a charge of 154 A · h before needing to be recharged. At a speed of 82 km/h, the average frictional force due to air drag and rolling friction is 1.34 kN. (a) What must be the minimum power delivered by the electric motor if the car is to travel at a speed of 82 km/h? ________kW...

Question 2 (a) A small electric vehicle is propelled by a motor with the performance data shown in Figure Q2 below. The motor drives a gear with 12 teeth, which in turn drives a larger gear, which is attached to the vehicle's driving wheels. The diameter of the driving wheels is 380 mm and the vehicle is designed for a speed of 30 km/h. (Note: Errors of +10% in reading data from the graphs are acceptable for the purposes of...

Case 1: ALL ELECTRIC SHIP Design the electric power system for a ship of about 50 meters long, 7 meters wide, 4 meters deep, 3 meters draft design, and it has a cargo capacity of 1000 tons. The powertrain should be equipped with electric propellers and a mix of supercapacitors and battery pack. The powertrain reportedly should enable a range of at least 100 km on a single charge. Search the Internet to find the best type of high...

2. The electric vehicle Tesla Model S has a drag coefficient of 0.24, a mass of 2100 kg, and a frontal area of 2.4 m2. The coefficient of rolling resistance of its tires is 0.01. Recall the density of air at sea level is 1.3 kg/m3. How much kinetic energy is required to overcome rolling resistance and air resistance (drag) at Autobahn speeds of 180 km/hr for a 200 km trip? How much useful energy (in MJ) and money (in...

Zipcar: “It’s Not About Cars—It’s About Urban Life” Imagine a world in which no one owns a car. Cars would still exist, but rather than owning cars, people would just share them. Sounds crazy, right? But Scott Griffith, CEO of Zipcar, the world’s largest car-share company, paints a picture of just such an imaginary world. And he has nearly 800,000 passionate customers—or Zipsters, as they are called—who will back him up. Zipcar specializes in renting out cars by the hour...
