Hi Jay -

There are no Ontario-specific regulations for EV conversions. EG. if you convert an already registered & licenced vehicle, you just have to inform the insurance company of the change.

There has been some discussion on the EVDL mailing list recently (http://evdl.org) that converted Canadian vehicles are breaking the rules if they exceed the curb weight after the conversion. (I haven't confirmed this.) This would be a federal (Transport Canada?) restriction. It would also mean that every conversion in the country is breaking the rules, since it's next to impossible to do a conversion with golf cart batteries that doesn't exceed the stock curb weight.

Your insurance company may dictate whether or not your vehicle needs secondary inspections (eg. TD Melloche Monnex may ask that a qualified EV person - such as REV Consultants in Ottawa - inspect the vehicle). This was the case with the ForkenSwift.

Insurance will be your biggest challenge - unless you have a friendly broker willing to work with you, expect to hear "no" repeatedly if you ask random companies via phone or online whether they will insure a conversion.

Insurance co's hate the term "modified" - when they hear that, they have visions of riced out, slammed imports and the high-risk nut jobs (profiling!) usually associated with them. Say "converted" instead, as in propane conversion.

good luck-
Darin

Motor bay pics!





(Yes, the cartoon colour scheme was intentional.)

Nice Photos, but what is the round thing right in the middle of the motor bay that looks like a round headlight?

I also noticed you painted the battery tie-downs to match the body color - nice touch!

Of course, that will be easy to do on mine, seeing as how it's black!

It is a headlight - off the forklift. In its new life, it's the precharge resistor for the controller.

Does that mean the controller shorts around it with a contactor after a time delay?

[MetroMPG]

When the keyswitch contactor closes, it delivers pack voltage to the controller. It's in parallel with the pedal contactor. There's no relay for time delay or anything, though. It only lights briefly (1 second or so).

It was also probably one of the most asked questions we got on the weekend. We tried to come up with a better, funnier answer than "precharge resistor" but failed!

Stopped by the forklift place again this afternoon to show off the new spanky underhood stuff. Had a good chinwag and one of the managers offered to sell us batteries at cost if we ever want a new pack. That'd be roughly 800-900, instead of 1200-1300 at current prices up here for the equivalent battery.

I thanked him and said I'd talk to Ivan.

But on the way home I got thinking: we don't really need new batteries! 20-ish km is enough range for around here.

You and your friend have built a really impressive EV. Looking at those pictures, I'm amazed at how well the paint has held up. I suppose you guys don't get as much UV damage...or is that shine from blood and sweat?

Why don't you protect the exposed metal (control arms, transmission, etc.) with paint or some kind of covering? Also, I would think a complete underpan would help keep salt spray and junk out of the motor bay.

I'm impressed...can't wait for the saga to continue.

Since getting back from the EV Expo, both Ivan and I had commented to each other that the car seemed more gutless than usual.

Yesterday I noticed that it seemed to be coming to a gentle but definitely perceptible "stop" when coasting down to zero in neutral. Today I jacked up the rear wheels and sure enough, the parking brake was dragging on both sides - and pretty severely too! I had a bit of difficulty turning the wheels in the air, and was surprised it wasn't more noticeable than it was when driving.

A couple of sharp hammer whacks on the drum freed it up instantly, but it stuck again on the next application. I'll have to pull the drums and lubricate the cable & pivots.

This all started after dragging the car up to Ottawa through torrential downpours for the show. Must have got some water inside the drums.

Combination of both, I guess. The exterior paint was dry and oxidized, but after a light going over with polishing compound, it really comes up nicely with a coat of wax.

It's all on the to-do list!

Had another first over the weekend: a guy pulled over a minivan while I was reinstalling the LED pack monitor (in the driveway). He wanted to see the car and show it to his two sons who were with him.

Turns out he's a mail man, and he'd seen Ivan driving by in the car a couple of weeks ago and noted the lack of noise. "It must be electric!" he correctly surmised.

He recognized the car when he was going by so stopped to come over for a chat. I gave him the full tour and promised to stop by his house next time I'm in his part of town so he can have a closer look at it in action.

very clean!!!!

I would do love one, I just need a 50 mile range

a sad attempt at a flux capacitor

Ok, if this has been asked i sincerely apologize I only was able to skim a couple of the 35 pages if it's already been asked could you point me to the correct page?

Have you or has anyone else looked into a transmission from a fourwheeler or snowmobile for this application? something CVT like?

[WannabeEVer]

I saw you guys on TV last night on CBC! looks like the whole ev conversion idea is getting peoples attention.

[bennelson]

Does anyone have a copy of that video? Us non-Canadians need to be able to see that video!

[WannabeEVer]

It took me a while but i finally found it. Here's the cbc link for the story: CBC.ca - Video

[WannabeEVer]

does your guys sound work for that video...or is it just my computer?

Sound works fine

[Peakster]

Awesome video! Looks like there's a lot of people across the nation getting fed-up and taking the electric plunge .
