Hello all.

Previously, projects for Tesla Model 3 and Tesla Plaid inverters were completed. Now I managed to get a printed circuit board for Tesla Cybertruck. I sent the video of the work to the big boss of this site. It probably takes 3-6 months to make a cybertruck. I plan to develop these ...

Great. Do you have a link to the code? I'd be interested to compare with my own efforts. Thanks!


Somewhere on this forum I have already shown an example code for working with a tlf chip.

Vector control is used.I use MPTA algoritm.MPTV is reaching now.The second core handles the resolver ...

Did you port the OI code or something else? Anything on github?

The program code is written independently.

Addendum:The control of oil cooling pumps is also implemented...Plaid has 3 of them.

Hello, colleagues.The next step was to write software for Tesla Plaid rear-wheel drives.A special feature of Plaid is the locked control chip and the rejection of direct measurement of the temperature of the electric machine.The task was difficult but interesting.The parameters of the Plaid and ...

Hello.

May be it help....

Test with original tesla pmsm 3....
Rotate it 1000 rpm without field weakening.
Measure emf at a given speed.
And further, approximate the emf voltage at 18000 rpm.

Now ,I don't have the original pmsm.

Maybe someone knows the emf pmsm of Tesla 3?

My thoughts ....
I have experience designing inverters for pmsm.

First, the self-induction emf is determined at maximum speed (without field weakening).

Power switches are selected with a margin.

For example:
If the self-induction emf at 6000rpm gives 500 volts of the voltage in the Ud link in ...

Hello.!
I have an incomprehensible problem.
I decided to cheat the discharge circuit.
Removed the key that switches the discharge resistors.

And I have a problem.
Without 12 volts, and a voltage ud greater than 70 volts, I have transistors turned on.
And the engine cannot be rotated.

When I turn ...

Hello.
It seems to me, there is a simpler option:


Finished debugging 95 percent.
The loader will try to post on this week.

There is a consideration:
Break the squib activation circuit with voltage OFF.
And debug tesla plaid inverter.

Breaks two of the three output buses.

What do you think of the idea to hack the tesla plaid inverter?

The probability, is more than 95 cents ...)))

The biggest problem, as I see it, is the squib.

I will prepare a bootloader project and post it.
A little bit later.
Now, I'm debugging the main program.

The resolver is used.
Bootloader is first loaded via jtag.

Then the main program and calibrations are loaded through can.

Private can is for debugging and oscilloscope.

There is support for uds download, but it has not been tested.

I have been developing electronics for many years and got a Tesla inverter on occasion I have PMSM control projects, including for texas instrument processors.
I decided to transfer my code to a tesla inverter.

Thanks Jack Bauer!

If the moderator posts a video, then that will be good.

I am also ready to answer questions about the program.

Hi guys!
I'm Dmitry from Russia.
It seems to me ... I was able to write a bootloder and foc program for tesla inverter 3.
