Exactly. Or find the wire inside the car, cut it and plug the electronics in between.


I am thinking of potential issues with the fix in the car.

If you use a separate external battery. Say for example you use a small 9v battery then regulator then resistor in parallel with Pp and Pe pins ...

Looks like this will become academic -- perhaps it played a part in prompting some belated action:


We will probably never know what eventually forced them into some action (assuming a solution does arrive or its not just more of there BS) Probably a number of factors. "Ludicrous feed" was ...

re:330 ohm resistor. Here is a screen shot of proximity circuit for CCS1 from IEC 61851-1 2010 standard. The value should be 330 +- 10%. From web address

Here is a more detailed description of the prototype attached. If anything doesn't make sense then please ask.

Give me a couple of days and I will draw something out. However a working circuit is very simple. You need an adapter with CCS2 pinouts at either end. On the car end you simply have a 1500 ohm resistor from the PP to PE pin. So the car thinks a charger is plugged in. At the charger end you could get ...

If anyone with a BYD is looking at this post as a solution to the Tesla Supercharger V3/V4 incompatibility issue. The issue is with the Resistor hanging off the PP pin to 5v. Communications on the CP line work correctly. Look for my post in the charging section for more details.

I would just like to confirm that the only issue is that the pull up resistor is incorrect in the Atto3. Thanks Uni22 and Johu, I appreciate the help.

Here is a quick description of my fix. As it is a relatively new car I wanted to avoid messing with the wiring so went with an external adapter. As ...

Thanks. It appears to be very difficult to access the back of the CCS2 plug in the car, so am thinking an external CCS2 - CCS2 converter and play with the PP line. Just need to find such a converter I can hack.

PP voltage on no load is 4.99 V
With 1.5K ohm resistor in parallel is 0.63 V

Thanks for the reply I appreciate it. I'll do some research to understand the potential issue. When measuring the PP voltage do we need to be connected to the Tesla SuC or can we use an AC charger?

As a background I have a 2023 Atto3 which will charge on Tesla V2 supercharger but not Tesla V3. BYD indicates that they will not address the issue. I believe the MG5 in the UK had a similar issue but MG supplied a solution. Hence I am thinking of creating my own adapter. The first step is to ...
