PEM, Power controller.

PEM, Power controller.

HI,

I am currently working on an Electrical propulsion project (not cars). We are struggling to engineer and produce a reasonable priced PEM.
The Model S power spec. is right where we are and the controller, I believe, would be perfect for us.
Does anyone know if Tesla are producing these them self or do they have a sub supplier?

Elon has said that his overriding aim is to promote electric-powered transportation (plus populate the universe). So I believe Tesla collaborates with anyone wanting to adapt or use their technology. By all means contact them directly.

I doubt you'll get insterest though. Tesla has, thus far, only dealt with large scale companies & orders.

If you just want a couple, then it's likely you'll be outta luck.

Vawlkus;
If it's a new design, intended for ultimate mass-market use, they might. R&D is something Tesla is very familiar with. And the "not cars" electric propulsion area is barely explored. Sounds intriguing, actually!

Many big ships and almost all submarines use electric propulsion. For boats of all kinds electric propulsion would be very sensible solution.

Thanks for the replys.. Does anybody know who to contact in Tesla or where to start?

BTW. I don't think I got one of my questions answered:

Does Tesla producing the PEM them self or do they have a sub supplier?

Nagero.

I answered that in your other thread of same question. Tesla PEM is Tesla build. AFAIK they have patented it.

Nobody makes PEM like Tesla, in Model S it is one tightly packed unit right next to engine and transmission, all liquid-cooled single module. Watch this: http://vimeo.com/18443073

(same is in blog http://www.teslamotors.com/blog/tesla-vehicle-engineering third video, but for some reason it doesn't work for me)

Thanks Timo. I couldn't remember if AC Propulsion had a hand in the R&D for Tesla's PEM or not. I remember there being a fight about it, but not what the outcome was.

Thanks again guys.

Again the big Q.... Anybody know who to contact at Tesla?

Vawikus - For the first prototypes Tesla paid a licence fee to AC-Propulsion. I remember vaguely that this was for the technique integrating the charger into the drive electronics. Later the PEM was completely redesigned and digitized. Tesla does no more pay for any licences.

Try calling the closest Tesla store and asking them. Maybe they have a contact at Tesla they can connect you with.

Alfred - It was not just the prototypes, it was all of the 2008 model, which is up through VIN 500. On the end of the PEM, on the driver's side, is a small label telling of the license from AC Propulsion.
