33 Machine electric 818e build- Sold! Headed to China!

[Bob_n_Cincy]

Great job Erik,
My 818S_E has been on hold while I work on the wiring diet for the 818S_ICE.
I like your Nose, I will be blocking off mine also. Remember flat black doesn't reflect police laser's.
A couple of suggestions,
Add some grommet edging on the CF motor cover. That stuff is conductive and will cut right through wire insulation.
I would add some nomex 410 paper between motor distribution block post. They are closer than I like.
Can't wait to see an electric version on the road.
Bob

...Remember flat black doesn't reflect police laser's.

But the headlights still do reflect, all too well. Well enough that they are all that is needed to get a reading.

Speaking of headlights......

HIDs. Nice. I got the normal ones (won't drive much at night) with halos, not the LED bar. Gives me an idea how mines will look, pretty neat.

[Samiam1017]

Are they an aftermarket headlight. Or did you modify the lights that came with the kit?

[Xusia]

Aftermarket. Look at the blinker.

[ehansen007]

Our project manager is testing for electricity....getting close....

[metalmaker12]

Lol love it!!!

[David Hodgkins]

How did you get that shot?!?

[Frank818]

That's easy with today's camera's/phone's burst mode.

It really is a shot to remember.

[jayguy]

That's awesome!

[ehansen007]

Video removed. More video coming soon!

[longislandwrx]

Nice! looks like you need some more lock and faster hands

[Olli]

Cool video!

[Bob_n_Cincy]

Great job Erik, and nice video.
It looks the low center of gravity is keeping the car very flat.
Do you know how much current you were pulling during you test drive?
Bob

[Frank818]

Were you producing movie trailers sometime in a past life?

[wleehendrick]

Need Moar opposite lock!

Great vid, but you forgot the rating

Hey Bob, Not sure how much current yet. We need to get the Xantrex hooked up. We had the motor controller gauge going and we noticed that we were dropping voltage and we brought it back immediately. We had two cells that were below 3V and one was at 2.6 so it's either bad or just lower than the others. We charged the two back up to match the others at 3.10avg and we'll drive it again. If they hold we'll bottom balance from there and then charge them up! Unfortunately we didn't get the video of doing donuts out in the street.

[Bob_n_Cincy]

If your at 3.10 you are already at the bottom balance starting point.
Which BMS are you using?
Bob

[wallace18]

Awesome!!!!!!!!!

[Rasmus]

Vroom vroom!

...err....

..ahh..

I mean... Wiii - wiiiiiiiiiiiiii!

Looking good, EH. Looking good.

[metalmaker12]

Wow your the man!!!

[Frank818]

There seems to be quite some torque in that thing! And the sound is better than I expected, maybe the tranny sound for some of what we can hear?

It may end up we don't need a BMS if one doesn't over charge or under discharge. Read page 6 and 7 if you haven't already: http://media3.ev-tv.me/cellcare.pdf

Yup that's our philosophy. Thanks for posting. And of course, as with any automotive power discussion we realize there are varying opinions. EV buffs can be as passionate as any group when it comes discussions like this and the BMS discussion is a big one. In this case, the grey cells are fairly new and we have to go with what has been proven to work to this point. The good news is that in this world, more now then ever before, development is progressing rapidly in battery technology. Hope you enjoy the videos and progress to this point.

What's your to-do list looking like?

[ehansen007]

Get the car home this week.

1. Weld in the harness tabs and install the seats
2. Get the windshield frame painted (maybe dip it?) and install glass
3. Get working on the body
4. Interior with center console to house 10" ASUS tablet

I'll hopefully have it ready for the HB show. I won't be painting it yet so I won't be doing a ton of bodywork. Mostly just touch up.

[Gary Livingston]

Nice Job Eric! Woohoo another EV Grin. Looks good. How did it feel? Looks like you are pushing it pretty good there after a few laps...lol I really enjoyed that.

I concur with the No-BMS direction. I'm not totally against some types of BMS's for certain chemistries. That said, I've been running my CALB's for several years now sans BMS. I've had no problem with balance. I Bottom balanced and under charge. Jack is right. You can always add a split pack monitor if you want. (Compares two pack halves to each other) This will give you early warning. Undercharging costs almost nothing in range. . . there is almost no capacity above 3.5 volts on LiFePo4 anyways.

Way to go man! Git er done!

[ehansen007]

Thanks man, the car feels quick at half charge so I'm optimistic of a full charge! I was able to do donuts pretty easily. Didn't get it on video though.

[blueoval_bowtie_guy]

No picture - it didn't happen!

Would love to see pics of the console with the tablet mount. Very interesting idea.

[esff32]

That is sooo cool. I love how all you hear are the tires squealing as the car goes around the building. Looks like its pretty torquey. Awesome Erik.

Best part of EV no rear main leak. !

Other good parts of EV.
- not having to wait for gas tank to fill in the freezin cold.
- instant heat
- no brake jobs (with regen)
- no oil changes... practically no maintenance at all... no belts, hoses, exhaust systems, fuel systems etc .
- low end torque. 150 hp competes with 300+ ice hp.
- the best of all..... "saving the world"

Sorry, Kenny. . . couldn't resist...

[ehansen007]

True, true. Some recent work includes a nifty little motor stabilizer (mostly for looks but it should work) as well as the harness tabs and floor

[ehansen007]

I had to reroute the ebrake and create a custom set up. You can barely make it out here. But it works pretty well.

[Gary Livingston]

Dang that motor looks sweet with the carbon fiber wrap.

[Frank818]

I agree it's really awesome.

[flynntuna]

Can't wait to see your amazing work at HB next month! You are setting the bar at a very high level.
