Development board for the is300h inverter arrived and it fits:)

Pcbs have arrived and they fit. Hurdle one passed:)

No not possible. You would need a battery or a power supply. The Tesla chargers will not run unless they see a battery voltage present.

Here is a video of my BMW E31 running on the dyno with a Tesla large drive unit and open source logic board.

To get the ball rolling. Here is a video detailing how to fit the open source Tesla small drive unit logic board to the Tesla current sensors.

That's on the way:)

Setting up a support thread for the open source Tesla Charger controllers. Wiki Gen2: https://openinverter.org/wiki/Tesla_Model_S/X_GEN2_Charger Wiki Gen3: https://openinverter.org/wiki/Tesla_Model_S/X_GEN3_Charger johu: I'm closing this support thread as it has become too long to be useful. Please ...

UPDATE : Sales of built and tested Tesla boards is now handled by Johannes. I am doing this in order to concentrate on new developments (model 3 etc) and focus on Toyota/Lexus in order to enable lower cost conversions. The opportunity is now there for someone to fill this gap. I would hope that if s...

UPDATE : Sales of built and tested Tesla boards are suspended as of 15/04/20. All orders placed will be fulfilled. I am doing this in order to concentrate on new developments (model 3 etc) and focus on Toyota/Lexus in order to enable lower cost conversions. The opportunity is now there for someone t...

Tom, the 177th pin is the big ground/cooling pad in the middle. They are using hall current sensors not sigma delta so that makes life a little easier. Good news is I have just enough info to make a stab at the design and it's more of a challenge reverse engineering something without it being in fro...

I'll leave the motor magic to Johannes. What I do know from experience however is that Tesla tends to do things the easy way. I recall being told how utterly impossible it would be to get the Gen 2 charger to run :twisted: Should only need a 4 layer board with a little trick from season 1 of Halt an...

oh yeah one other thing Johannes, this is a reluctance motor so will be a new challenge:)

Thanks Johannes :) Tom wins the prize:) Won't be quite as straightforward but Elon made the approach possible on the 3 as they no longer use a separate FPGA for reading the sigma delta current sensors and hardware shutdowns. The TI C2000 device also has the very same pitch as the STM32F103 just in a...

I was never any good at keeping a secret. Probably why I like opensource so much :) To date I have refused two offers of Model 3 drive units as the parties involved wanted me to keep everything under wraps with no sunset clause. I have no problem doing non open work but something like the M3 needs t...

You would need the gearbox with the aux oil pump (beware many ebay sellers remove this as it is a common failure part on the gs450h), inverter, hv cables and if possible the lv harness as of course all the connector plugs are custom. Started in on the GS450h inverter today. Our friends in Toyota are...

I'm using a GS450h gearbox in my E65 conversion. At 2640kg it should prove the system:)

Oh it's very much possible :

Naturally this guy decided not to share (probably planning to be the next Elon) so I'll just have to go do it.

Released a development board design for the Lexus IS300H inverter :
https://github.com/damienmaguire/Lexus-IS300H-Inverter
Uses the Hübner brain board and a jumper to select between running the MG1 or MG2 inverter.

I also had a recent donation of an ampera inverter. Must go get it running:)

I like it:)

First look inside the GS450H inverter. Uses the same connector for the igbt driver board as the Gen 3 Prius.

Final test fit with a cardboard template to check size and hole location before ordering prototypes.

Next up on the bench for hacking is the Lexus IS300h inverter. I believe this one is also fitted to the new model GS450h and LS hybrids also. Have another few Lexus inverters on the way including a few 2009 GS450h units that are available quite cheaply. Should work out nice for people who need more ...

Thanks Johannes:) I can't wait to see two leds blinking on the one board. Initial release of design files over on Github for those interested :
https://github.com/damienmaguire/Prius-Gen3-Inverter

Expect updates before I order prototype boards.

Done
