In 2008, the students at Waterloo Collegiate Institute took up a challenge issued by the Reduce The Juice Foundation and began
to create a solar-recharged electric vehicle.
While the mechanical aspect of the project was well understood, there
was little information available with respect to the electrical and control elements.
An original vehicle design was replaced
after students from the University of Waterloo Alternative Fuels Team (UWAFT
) provided engineering support for a stronger-framed vehicle.
new design would require close to a year to build, and it would be many months before the students would be in a position to start
adding the electric motor, batteries, and controller.
With support from Cybersystems Inc and the Navitas Vehicle Systems division
of Accelerated Systems Inc, a small-scale "test bed" was created to teach the fundamentals of motor control.
of the project included:
- basic electric circuits and diagrams,
- learning to solder,
- learning to "unsolder",
- safe sequencing rules
- switch requirements (key, direction, "deadman")
- DC motor voltage/RPM relationship
The knowledge gained in this project was applied to the full, scaled-up eCar project.
The eCar was successfully
driven in the 2009 Oktoberfest parade.
