Coyote: thanks for that. I've got the files converting in VirtualDub.

hey, you should put some higher-than-youtube video quality on your site so then we could actually read what the gauges say which is really hard on many youtube videos :)

I have lots of bandwidth if you need it :) my service is for 2tb of traffic a month.

ForkenSweet! Congratulations on your very laudable achievment. :thumbup:

Nice, congratulations :)


So, what's next for the forkenswift? You were talking about a controller bypass -- is that in the works with your fancy clutch safety?

MetroMPG 10-27-2007 02:54 PM

Thanks, SW.

Went to the EV meeting in Ottawa yesterday.

Get them! If you don't use them for the car I'm sure you could figure something else out interesting for them...electric scooter!

MetroMPG 10-30-2007 06:31 PM

Yeah - no shortage of things to do with a bunch of batteries... Just time!

MetroMPG 11-04-2007 05:52 PM

I picked it up this evening. We've got a few issues.

MetroMPG 11-04-2007 05:58 PM

Also: since last posting, our 24v charger stopped working.... and with help from an EVDL E.E., I fixed it! (It was a burnt out SCR on the circuit board, which I replaced/upgraded to a more robust component on his advice.)

SVOboy 11-05-2007 05:24 AM

It's so cool how you ev people help each other out so much!

Whatever happened with that batteries you just got?

MetroMPG 11-05-2007 05:47 AM

Yeah, the EV community is pretty awesome.

Gearshredder 11-05-2007 08:13 AM

hey when you find out which of the batts are strong and weak, i dont know if you know but there was an article somewhere telling how to arrange them so that you get the most power out of them.
The battery resistance causes the batteries closest to the power connectors, depending on how arranged, are drained faster.

Edit: heres the link: https://www.reuk.co.uk/Interconnectin...ttery-Bank.htm

That's really interesting!

The example only discusses a parallel string though - four batteries of the same type connected so the pack voltage is the same as the nominal individual battery voltage. I'm not sure it applies to a series connected pack, though, which is what most EVs use (though some use several series strings which are then paralleled, or a series string with each battery having a buddy (individually paralleled neighbour).

EDIT: there was actually a discussion in the EVDL about where to place the ammeter shunt in a series connected pack to measure current. The poster asked: will I get the same current reading if I connect the ammeter at the end of the pack vs. somewhere in the middle, between 2 batteries?

The answer was: in a series pack, current flow is equal through all batteries. So I think the example you linked to only applies where batteries are paralleled. Still good info though.

It's a transmisison mount on the driver's side "frame rail". There seems to be a lot of play in the big rubber bushing, plus it makes the funny sound when the drivetrain is torqued up.

For anyone who might be interested in joining the Electric Vehicle discussion mailing list (EVDL), the link above (https://www.madkatz.com/ev/evlist.html) contains outdated subscription info. The current info is at

Thanks!

MetroMPG 11-06-2007 07:25 PM

Thanks for pointing that out - I changed the earlier reference too.

Question is: do those bushings fail and allow excessive play? Or am I just hearing a new noise with potentially the same amount of play that was there before?

The rubber in these mounts does tend to dry rot, crack, and fail, causing a loose mount. The cheapest and easiest solution is to go to AutoZone (do they even have those in CA?) or equivalent, and get a product that comes in a caulk tube called 3M Windo Weld:

Get a caulk gun, load this up, pull the mount out of the car, and just fill all the voids in the rubber part of the mount with it. Let it cure for about 24 hours before putting it back in the car. I have in the past purchased urethane inserts for my mounts and even expensive urethane mounts, but this stuff is 90% as good and WAY cheaper. It is messy though!

Excellent tip. Thanks, Dax.

Hi! Just found your thread. You do GOOD WORK!!!
 
Thoroughly enjoyed reading you and watching your videos.

I like your approach: Jump in head first and engineer around obstacles as they pop up. I am a minor scholar of Thomas Edison and he used the same approach.

Unfortunately, this spirit of discovery has all but disappeared today. I am trained as a scientist and I believe people permit technology and communications to confirm every new idea is impossible or impracticable.
e.g. "Were it possible, one would already be doing it...!" The same sort of thinking which nearly shut down the US Patent Office in the 19th century.

We are fortunate to have some hardy pioneers as you and Ivan in your generation. Our society and our planet depend upon you!
