TdS Report #18: Team Profile: rEVolutionaryride

Liz Lovell said, "North Haven is a 7-by-12 mile island 12 miles off the coast
of Maine. We live in the town of Rockland. We converted a VW Vanagon Microbus
into battery-electric vehicle. It will be used at the school for picking
people off the boat and bringing them to the school, or transporting kids for
projects. It matches our needs exactly."

Neil Thayer added, "We picked it for it's functionality, it holds a bunch of
people and has 4-wheel drive. It is great for island life. We get snow that
gets pretty packed down on the roads and gets icy." The 4-wheel drive will
help then.

I asked how they would charge on the island. Wind power? Liz said, "I think a
wind tower will be built as a project next year."

Neil has been working on the project for two years and has already graduated.
The rest of the team is juniors. "We only have one senior. She didn't come."
17 people did. (The high school class is 27 students.) The van has been
drivable for a couple of weeks.

The idea originated with Phil DesLaurius, an electrician on the island. "We
work on it and he comes in to check the wiring, give us new ideas, and make
sure that it is safe." They have had help from other people on the island.
Two students made the steel battery boxes with the help of the welder on the
island. I could see the metal box which would support the first bench seat.
While we were talking, a pair of students were working in the battery box.
Both were wearing rubber gloves and safety glasses.

A 100 Watt solar panel on the roof helps maintain the 12 Volt battery for
lights radio and such.

I was particularly impressed by the control wiring. It is laid out with super-
neat care. Every wire color coded and ever connection clearly visible. The
charger, DC-to-DC converter, traction controller, contactor and relays were all
easy to inspect. A clear plastic cover kept fingers away. It had originally
been intended just for display, but they are now going to add forced
ventilation so it can be left in place during operation.

Lifting the cover that held all the circuitry revealed the motor mounted on the
rear transaxle, with both a first gear and a low gear, and a locking rear end.
All wires to the motor and solar panel are in flexible conduit.

Program blurb A spunky group of junior and senior physics
students from the smallest public high school in
Maine (on an island, no less) have spent the last
18 months making a perfect island car: an
electric 4WD Volkswagen Syncro 7 passenger van.
This entry has been an all-island effort, joining
students, a boat electrician, the town's welder,
and island artists.
