The Topsail High School electric vehicle class is dedicated to the pursuit of exploring alternative solutions
to internal combustion vehicles, and increasing environmental awareness as well. The students work hard to
secure funding in order to achieve their goal of converting normal vehicles to clean electric power. Thus far
the Topsail EV class has successfully converted three vehicles, and have won over 70 trophies while competing
against other schools with similar programs.
Topsail recently took the 144 volt Paseo and ran in the auto cross competition at UNCW. The event was put on by
the Cape Fear Chapter of the Carolinas Region of the SCCA. They were kind enough to let us run our laps free of
charge. The car ran about 9 seconds off of the fastest time recorded that day. The car could have performed
better if it had auto cross wheels and tires, because the car actually gained such high speeds on the long course
that the tires were not able to handle the corners very well. Overall it was a good experience, but now we are
currently working on the conversion of a 1996 Ford Ranger, that was donated to us by a man from Georgia.
In 2000 the first year EV class converted this 1996 Ford Ranger. The truck was donated by Sanders Ford in
Jacksonville, NC, and all of the conversion parts were purchased from EV America. The total cost for conversion
was $5,500.
The Students began the conversion process by researching conversion techniques, design engineering the vehicle
for the conversion and providing supporting data for the calculations of expected range and top speed of the
completed conversion. With the engineering process complete, the students began the arduous task of securing
the necessary funding. The class developed a sponsorship package to present to local businesses and individuals
who may have wanted to donate money or services for the completion of the project. After securing the necessary
funding they began ordering the parts for the conversion.
For two months the Ford Ranger was transformed into a clean running electric vehicle. During this time fabrication
of battery boxes, motor mounts, transmission coupler, and control board were completed. The wiring and electronic
component connections were made and tested for the maiden voyage. The newly converted truck rolled out of the garage
three days before the final event of the EV Challenge competition was to be held in Raleigh, North Carolina.
The final event was a success and the team won three trophies including the rookie of the year title. The future
looked bright for the electric vehicle program and sights were set on more conversions in the coming years.
The 2005-2006 class was successful in converting a 1985 Pontiac Fiero. The car began its life as a six-cylinder
sports car that was notorious for overheating and catching fire. Obviously this spelled the demise of the first
mid-engine sports car produced in the United States. Our goal was to retro fit the Fiero with electric drive train
components and batteries to create a cool running, environmentally friendly mid-engine electric vehicle.
The conversion process was mapped out early in 2005 as the EV class had acquired two Pontiac Fieros, which would
serve as donor vehicles. The first step was to identify which of the vehicles was best suited for use as the rolling
chassis. This decision was easy since we only had a title for one of the cars, and the other car, which was donated
by West Carteret High School, could not be used since it had gone through a previous conversion. The next step was
to isolate the best parts off of each car that would end up on the finished vehicle. While this process was going
on another group was taking the combustion engine out of the vehicle that would be used as the finished vehicle.
After removing the internal combustion engine, the electric motor was then mounted to the cradle of the car, which
houses the motor, transmission, and the rear suspension. Next we wired the car and put in the motor controller, which
would soon be connected to the battery string. Following this process the battery boxes were fabricated and mounted
to the car. The car was multicolored since parts from several different vehicles had been used to piece it together.
The car was sent to the painter about a week before the final event and we got it back just two days before we left.
The final event was a success for the new car. It performed better than expected, and helped the team to bring back 14
trophies including first place overall. This first place overall continued to the teams dominance of winning first
place since the 2003-2004 final event. First place trophies received included vehicle design car class, vehicle design
truck class, troubleshooting, autocross car, autocross truck, oratorical presentation, vehicle range in the car class,
and vehicle range in the truck class.
