Default EV turbobrick - the turbobrick way?

Since I'm still kind of stoked on the idea of building a hybrid/full EV turbobrick, let's have a discussion on how to do it with cheap junkyard/Chinese parts.

Stuff I've ran into:
Fork truckmotor on the driveshaft
https://www.diyelectriccar.com/threa...good-one.7598/

Chinese hub motors for the front wheels maybe?
http://www.cnqsmotor.com/en/article_list_91.html

Tesla motor, this guy is doing a pretty cool job with those in his shed, recommended watch:p

Mercedes 48v e-alternator setup, fast and simple but weak?
https://x-engineer.org/automotive-en...s-continental/

Theoretical benchrace budget let's say 2-3k including some Chevy volt batteries, or a DIY laptop battery pack. Tesla stuff is also good but $$$ from what I've seen, in a wagon the spare wheel well should provide plenty of space with decent weight distribution

This style is pretty interesting to me. A mild hybrid approach seems like a reasonable option.

I wonder how much all those components cost. Could be a good way to get great MPG in an old brick and not have range anxiety issues.

Yes I had a look at them a few years ago and the motors went for about 1000€ at scrapyards, they came on the latest mercedes a-class back then. Continental used to have a page on the concept with some numbers I believe.

Kl racing and ACM offer a b230 rib belt conversion so assuming the unit has the normal alternator mounting, you'd only be looking for a cooling setup and the electrical system

Hi Hubert,

I understand, however I'm at a more hobbyist angle here, simple parts that bolt together. 80% Vs 99% efficiency won't make the difference on a simple hybrid brick for me. I do the electrical engineering for work, the hobby mechanics in the weekends for fun

Just add some sketchy mounting interface and some batteries:

Pulled this from a post from the future:

Here are some places that sell components for the DIY EV community. If you know of any more, please add them.
Most of these places will sell a "kit" with a motor and controller that are matched well. This will give you an idea of what the costs will be if buying new, and using a decent quality product from known suppliers.

The APD drives are neat, but they wouldn’t be the best choice for a ground vehicle like a EV
Volvo.
Their power ratings are with constant air flow (they’re designed for electric planes), and if you want the controller mounted on your roof or bumper, that may be ok.

They also can’t handle a significant amount of regen current, which would be a really big issue in a car EV.

It’s what their website says.

Keep that in the other thread, please. This thread seems to be aimed at cobbling OEM stuff into volvos. I will clean this up later.
*edit for HE WHO SHALL BE OUTRAGED: "cheap junkyard/Chinese parts."

I mean, the internals of the motor I posted is OEM for a large EV motorcycle company.
If you’re going strictly EV power, you’re going to want a much larger motor. If you want a hybrid setup, the ME1507 is really hard to beat from a cost/ performance/ simplicity perspective.

Oh, that's not much of a budget. A LS swap is much more, and that's _just_ an engine swap.

Adding an e-Alternator seems like it might work, and would give better acceleration from standstill. What sort of Hybrids are showing up in your local salvage yards these days, and do any of them have anything somewhat bolt-on?

I haven't kept up with the production Hybrids -- it would be great if one of them (probably an AWD) had a usable electric motor built into the rear axle/differential that you might be able to use for a RWD Brick (still Hybrid).

Whatever you do, I'm guessing that you'll need a new aftermarket motor controller (think MegaSquirt for electric motors), unless someone knows of good tuning package and/or hacked production controller??? That's hundreds, or more, of your budget.

Toyota Highlander had one in the rear but I think (it was a school a long while back) the front hybrid system was like a prius but v6, the rear was electric-only.

The bigger hybrid GM SUVs used a very nice Remy electric motor. That’s getting into the power levels to move along a brick well enough (150 peak HP I think?).

Using an automatic without a torque converter would go a long way into extending the operating/speed range, as well as extending the battery run time.

I’m waiting for cwdodson88 to come in here and tell us where all the cheap e-motors and controllers are
I know the company he works for sells AEM interfaces, and I assume they work with their controllers.

There’s currently a small company working on integrating a small ~15hp brushless DC motor into the drive lines of pickups. Just enough to give a nice boost of passing power and recover some energy when braking.
