Program Description:
Methacton High school has an electric car and has recently built a solar photovoltaic solar cell array to charge the car. This program will show how battery electric vehicles work, how solar cells produce electricity and the practicality of using renewable energy to charge an electic vehicle - - from both student and teacher perspectives.
The car itself has a fiberglass frame, three wheels and runs on 17, 12-volt lead, acid-gel batteries. The car, with the batteries, weighs 2150 pounds. The three wheels make it lighter, producing less friction, which demands less energy. The Lorax has a three phase AC induction motor. The Solectria controller takes the 204 volts from the batteries and converts them to a three phase AC pulse to make the motor run. It has 700ft/lbs. of torque at the drive wheel. The car has been driven at speeds of up to 80 mph. The first part of the presentation will focus on its design and performance.
This is an 'open forum' videoconference event - - students and teachers are encouraged to ask questions throughout!
About Methacton High School's Electric Car Club:
The goal of our club is to educate the public one car at a time. The program will focus on how the electric car was built, how it works, the positives and negatives of this particular car and how we are using solar energy to charge the batteries. Our goal was to no longer be dependent on the local utility company (which provides nuclear energy) and make the car totally renewable. Any background information that teachers could provide on these topics would allow their students to have a greater understanding for the material being discussed.
