Re: Tesla Model 3

Tesla unsuccessfully sued British television show Top Gear for its 2008 review of the Tesla Roadster (2008) in which Jeremy Clarkson could be seen driving one around the Top Gear test track, complaining about a range of only 55 mi (89 km), before showing workers pushing it into the garage, supposed...

Arlo, Awesome build, watched alot of your YouTube videos today. I had a question about your inverters and saw you prefer PMs on this forum, but I think I'm "too new" and it won't let me send PMs. Love the CRX build! It will let you Send PM's But if its related to this EV build at all you should ask...

Re: Tesla Model 3

I think the Model 3 is a lot more fussy about charge adaptors than the S and X. Guy here in Perth has been struggling with his 3 on the Circontrol Trio chargers. About 50% success. Got a bit of a story today from a local with a 2015 leaf. IN 2014/2015 he said someone from Japan came and put all the...

I watched one of Arlin's videos on the Axiom he's using in his Honda and he suggests there might be Torque Vectoring possible/coming? I assume Traction Control is already possible through VESC software anyway, but are there plans for Torque Vectoring to be available or is Arlin developing this just...

Why build this boost converter and not just use field weakening ?

Arber, you want to measure after the boost converter, so at the power stages.
Yup boost converter = fail. This is only added losses!

Just because someone else did it doesn't meen its the right way to achieve a goal.

Yeah I used a 100:1 voltage divider to bring it down to 0-5v 5v = 500v Then a isolation chip this one with a op amp and brought it back up to 0-5Vdc isolated on the output. https://docs.broadcom.com/docs/AV02-3563EN I have 2 verions.

Only way for an OFFICIAL time is for Nuremberg to put on an event and the cars to come as OEMs otherwise Nuremberg considers it unofficial ......... Yes, but that means you wont see an official time for Tesla for a long while as it is not a production car. Personally, i am more interested in. Disco...

Re: Tesla Model 3

A sadly misinformed pair of Tesla fan boys. They need to get their facts correct. There was no lap time , unofficial , or hand timed, because Tesla never ran more than one lap without recharging. And that means you do not cover a full lap..the exit is before the start point. They did not need hand ...

No time is posted because they have yet to run a 7:20. The data logging reveals that putting together elements of other laps, the car as is will run a 7:20. They are running in a manufacturers pool, they are running into traffic multiple times a lap. Theoretical lap from peak deviation is a standar...

Re: Tesla Model 3

Design constraints really I see it as, as we need more power we have to up the voltage so we dont end up with a bus bar system thick as the back of a distribution switching panel. But if a car has 100kw max then 800v is not needed and the tesla can control more power with less volts so Porsche syst...

Re: Tesla Model 3

Guys, You can charge just as fast at 400v as you can at 800v As for efficiency its very close to a wash... VERY much all the same just 400v needs 2x the thickness of wires. But its about 100x less likely to kill you and 50x less challenging to get the systems isolated and safe. Think BMS...... You B...
