The contol board from Tesla Gen3 charger

Not sure is anyone is interrested, but I have "extracted" the control module and took some pistures. As I did not want to remove the phase modules and completely strip the charger (as I believe its working), I took sligtly different approach.
The board did ...

Hi All,

Please can someone clarify "Activate" and "Eanble" signals?

The Gen 3 charger Wiki pagehas this picture image.png which suggest that pin 3 is the activate and it needs 3V signal, but the table under suggest pin 3 to be low and pin 4 to have 3V.

I have connected my charger and when pin 3 ...

Is there a way to use the Tesla OBC Gen 3 for fast charging??


I guess that depends on what "fast charging " means for you.

I'm working on a DIY DC charger project where the plan is go use pyPLC combined with tesla gen3 charger (one to start with) to have 18kw charging capability at home for a ...

Hi All.
Does anyone have the schematic of the charger module?

I'm specifically interrupted inthe input section on the AC side with intention to examine the component rating for possibility of running the charger from DC (HV battery) supply.

Any info, help, suggestions will be greatly appreciated ...

I have decided to take one unit completely apart(it's faulty for sure so..)..
So here are few more pictures..

And yes there is a burn mark next to one of the diodes I guess..
If anyone wants to see specific detail just let me know

Then I have enabled HV DC and sent the two messages ...

No luck getting this unit to do anything useful.
I have another unit (same part number) and I'm trying to replicate what Damien did in his video. Unfortunately no luck so far getting it to do DC/DC to change the 12v bat. Did not get around to try V2L or hv battery charging yet.

Can anyone help ...

I think it is the same unit, but Damian will have to confirm is unit is also EP2CCU6625A.

Once I test what is still working, I will probably try to get the PCB off to dig deeper (especialy if nothing is working).

Hi All. I got my hand on "faulty" MG5 on board charger (EP2CCU6625A).

I did not have a way to tedt, so I decided to look inside 😉
Not the best idea ever, as due to the cover being glued on, it was hard work and i have damaged the unit a bit.
So I'm sharing info/pics, so you don't have to repeat my ...
