Tesla Charger Support Thread

[Kevin Sharpe]

Yes i did one more mod. That is rather important.

Can you open an issue on Damien's charger github so that he can decide whether to implement this change?

[joromy]

Yes, but this is only an issue if you turn on/off 12V power to your charger.

Does anyone know what they weigh?

~16kg

Smuggling one back from the US worked out, thanks Kevin.

I got a -G slave, no obvious damage. Rev 4 charger board populated today, just waiting for the fancy 24 pin connector to arrive. I'll try to fire the board up and load the firmware in the meantime.

I got the sketch compiled and loaded into the board OK, and it looks like it's working to some extent.
Is there an easy way to check that the micro is talking to the modules, before I install it in the car?

Hello to all ! I purchased the Tesla gen3 charger and I need advice on this:
1. I want to make a board myself, but I can’t find software for gen3 on github (only PCB info)
2. Is the board from the second generation suitable for the third generation changer ? Why am I asking - the second version board is constantly evolving and there is already a fourth version with the ability to use Chademo (and other) protocols for charging station side. (depend on software)
Advise which board to use for the third version of the charger so that there is the possibility of working with Chademo controller (or Tesla Super charger ) in the future

P.S. I have a Tesla Model S P85 2013, unfortunately single-phase, and I want to do Chademo Station (or may be Tesla Super Chardger) for personal use (but of course I have no protocol information yet for charging side)

Thanks!

I'm not sure I understand this comment... If you're trying to use public CHAdeMO and SuperChargers on your Model S then why not just buy the upgrades from Tesla? This is much easier and cheaper than trying to develop something yourself. You'll find the CHAdeMO adaptor hardware in the Tesla shop (here) and Tesla will need to turn on fast charging in your car.

If however you're trying to develop your own CHAdeMO or SuperChargers then you could 'simply' stack a load of Gen 2 chargers together (five for 50kW) and pay someone to develop the control software... I'm sure Damien would scope the project for you (his consultancy fees are listed on his website (here)).

I have one-phase Tesla from US, so for max power I need 3-phase charger at home (for equal line loading) . Also I am from Ukraine and want to have mobile 3-phase charger on the board (because Super Chargers is absent in Ukraine).

[Wise]

1. ..... can’t find software for gen3 on github (only PCB info)
2. Can a third-generation charger be turned on in parallel to achieve fifty kilowatts?

[Jack Bauer]

Gen2 and Gen3 charger controllers use the same software.

Rewiring the charger in your car to support 3 phase will be difficult given the US car connector and the modifications that are required in the HV Junction Box.

What you could do is use your Gen 3 as an external charger and plug it into your cars charging connector. You would need to emulate the supercharger or CHAdeMO protocols to communicate with the car but the advantage is that no changes would be required to the car itself. Unfortunately, this would require the development of software that does not exist today and it will not be trivial.

Thank you!
Can I use gen2 board for gen3 charger ?
I am asking, because gen2 board is booming ! (V4 already)

[Kevin Sharpe]

2. Can a third-generation charger be turned on in parallel to achieve fifty kilowatts?

You can run *any* number of Tesla Gen 2 chargers in parallel. A Supercharger is ten Gen 2 chargers in parallel. I don't know whether Tom's software has any limits on the number of chargers and doubt it's been tested with more than two Gen 2 chargers.

AFAIK no restriction on running Gen 3 in parallel but doubt it's ever been tested.

That's right, I did not want to redo the car. Initially, I meant an external charger.

OK, so the answer is yes you *can* do it but none of that software or hardware exists today.

In a nutshell you will need both hardware and software for a CHAdeMO (or SuperCharger) charger controller that follows the standards close enough so that the Model S will work. This is a significant amount of development effort. It will be much cheaper to buy one of the low power CHAdeMO chargers from China.

Yes, thanks, I'm in the know. But I want to do it myself. Maybe this is unrealistic, I just want to try.

Great! I'd recommend you start with CHAdeMO because more of that information is in the public domain. Here's the JLD505 software used by various car side development efforts;

And here's some recent car side hardware/software development;

70+ pages on the MNL forum... don't know if they ever built a "Mini-QC Rapid-Charger" or just posted about the idea

Thank you ! Will try Chademo.
Yet one question.. Can I use gen2 logic board for gen3 charger (with any manipulation) ?

[Kevin Sharpe]

Given they use the same software why not compare the schematics and decide whether you can cope with the hardware differences?

Clearly, this is all I wanted to know so as "not to step on the rake".

Thanks.

Here's a video demonstrating what you are trying to build (in your case replacing the charger power stage with the Tesla Gen 3 charger)... unfortunately AFAIK the CHAdeMO control hardware/software was never shared despite the project being "open source"

[Roadstercycle]

Are we still rolling the dice on buying a Gen 2 charger and crossing our fingers it works? I'm just about at that point and I'm not overly thrilled with running an ELCON charger.

Damien has two controller boards for me and i'll try to spend some time testing the chargers that we have next week.

Thank you Kevin, that will help a lot in the near future.

Hi Kevin, Any luck on testing chargers?

Hi ! I want to buy a printed circuit board for Tesla Charger GEN2- is it the fourth version?

[bulletbug]

I'm attempting to build a Gen2 V4 board. I've found a few errors in the Gen2V4 BOM that may need correction.

2 types of errors:

1. Qty. field not matching qty required (this becomes an issue if you use a supply houses BOM building copy and paste function to order like I did.)
2. Items required on board, not found in BOM[/list]

Quantity related items that I believe are incorrect:
LED 1, 2 - qty shows as 1
D1,2 - qty shows as 1
Z1, 2 - qty shows as 1

Required Items not included in BOM:
R20
C115
C114

On these last 3, can someone help me understand the component parts that are required in these positions? MFR or Mouser part numbers would be great.

[Jack Bauer]

V4 BOM updated with corrections. Thanks for the feedback.
