Re: Tesla's NACS and the Future of Fast Charging in North America

It would be a "man in the middle" that would read incoming data from either direction and repeat it out the other side. The concern with just passive sniffing is you don't know which way the data is coming from. Tesla's documentation on NACS isn't thorough enough, and I'm too cheap to pay...

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)

It is a model Y, with CCS2 charge port. I use my own SECC in my test, so the detail in SLAC timing and CP signal could be different here. From what you described it look like PEV does not go into sounding state, possible cause could be EVSE pwm signal is out of spec, check the timing and voltage lev...

Re: Tesla's NACS and the Future of Fast Charging in North America

Will share the pcap file when I get back to the lab, in around two weeks. It is an incomplete session, time out after 12 sec at pre-charge. The session is to find out if Tesla close DC contactor during simulated charging, but it does not. Regarding your plan to build an adaptor, is it passive sniffi...

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)

Ok I have already tried the scenario with 2 amps in the response but no difference. And if I actually follow the requested values from the car both timeout pretty quick after about 20 seconds. Hmm...it does not check during pre-charge, but instead does this during charging. Can you post the pcap fi...

Re: Public DC chargers experience

Don't know how you obtained the data for each EVSE, but if I understand it correctly the under current column you have "target" which is set by the EV and "delivered" which is reported by the EVSE. From this, it is look like all chargers that you collect data from seem to behave ...

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)

Luckily, the Ioniq does not timeout such fast. Latest results: Without drawing energy from the port, it keeps the contactors on for 10 minutes. Then it turns off, but a new session can be established after disconnecting and re-connecting the plug. Did a session where I connected two bulbs with 230V...

Re: Open source CCS using AR7420

For Q3: Regarding the power-relay in the charger, I have no experiences. Basically it needs the possibility to avoid voltage on the plug, not sure whether this needs a relay. What it definitely needs is some circuits to fulfill the cable check and the precharge. I do not have details regarding this...

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)

I have let it run for some minutes, there was no timeout. Will run longer tests hopefully soon. The "simulated precharging" means: THe charger sends EVSEPresentVoltage with the same value which the car wants as target voltage. This makes the car thinking, that precharging is successfully ...

Some small progress on the Tesla SuperCharger: SLAC and TCP connections work perfect, also with the headless Raspberry3 as controller. In contrast to the other chargers, the SuperCharger use only 8 characters session ID instead of 16. This case is not yet considered in the OpenV2Gx. At the moment t...

Re: Hyundai Kona CCS controller

The other approach would be to pretend to be a CCS charger and initiate a charge session to get it to close the contactors - this would be a cleaner approach and may also be applicable to other cars. The only possible hurdles is that it may time out if no charge is received, or it may complain if c...

Re: CCS2 Controller failed at CableCheck state

You are truly expert on this, kudos.

I have found the bug, will fix it and let you know the result.

BTW: It appeared that ABB also require multiple messages during Charge Parameter Discovery state, but it probably more forgiven to this type of error and let the session continue.

I forgot to mention, the last response message from IES also indicate that the insulation testing is ongoing and few second later it show error screen, this may be due to my side terminate the session, see attached picture.
