Re: Comm Required on some public slow chargers?

It always stays at 50%ish PWM and continues to stay like that with PLC.(Haven't got the foccci yet so no proper comm yet..)

Re: Comm Required on some public slow chargers?

I have borrowed an osiloscope, and have tried quite some chargers(10 different brands), and i have managed to get all working.
I had to make a switch so i can switch the 1.3k resistance on and off the line.(many of them required it to go thru the states.)
Also, i have found a charger with PLC in it ...

thanks for the useful info, I'll probably use the 3aef7c9 commit then.... or 2cc0fae

Re: Comm Required on some public slow chargers?

Currently, I don't have any osiloscopes but i have a friend to borrow one.
and the chargers that i have tried is all cable with plug.
for the focci, i can skip the contactor drivers and some unnecessary ICs and order with only STM and qca + some supporting components only?
because the homeplug ...

Re: Comm Required on some public slow chargers?

"normal" EVs are charging without any problem on the charging spots that my resistor diode setup fails, so far saw Tesla, Ioniq 5 and etc.
I wonder what hardware I will need to test it,like ordering foccci with only the essential parts?(Modem, supporting components and STM?)

Re: Comm Required on some public slow chargers?

I do already think quite most of the chargers here are not backwards compatible.
except some old ones that really does not have any PLC inside, most of them get updated and gets the backwards compatability removed

Re: Comm Required on some public slow chargers?

I'll try to do that, State B on plugin and flip of a switch then State C. but i did hear about the news on some chargers getting a PLC with it for some stupid reason(preventing fire from limiting the charge to 85%) and previously working charger that did not care with stupid charger not working ...

Comm Required on some public slow chargers?

Hi openinverter forum, first time writing at here since getting large help of infos from here at building my own j1772 to 220v outlet adapter.(just a resistor and a diode on cp pin)
I have realized that some public slow chargers requires a plc communication to charge (even tho its not a ccs!),
so ...
