Well, the use case is not specified in the good old CCS standard from 2012, but latest version wants to address this use case, too. So the "old" cars have some room of freedom, how they react in the case of negativ current. Some are happy for a while, some are ending the session quite fast, and some, like the MG and the self-made Touran just work without complaining.

Don't wait for it, build it :) I think Growatt would also work but this is SunGrow :)

That'd be cool. With REST API for all communication, none of that stupid modbus crap

Hi thermoratz, bist du schon bei den Nordkap-Vorbereitungen :-) What was the question? You mean which cars are supported by this approach? We collected some experiences in the openinverter forum, topic "Drawing power out of CCS port". Or do you mean which electronics of the Touran we are talking to? This is the open source CCS controller, aka Foccci. Basically at the end each CCS car is a candidate for such an approach. With some exceptions: Your 800V car would require an hybrid inverter that supports this voltage. Some cars are not happy with closing the contactors without beeing charged, e.g. the good old Ioniq classic terminates the session after 10 minutes of "not been charged."

I communicate with the CCS charging interface in the car. Inside the car the CCS interface communicates with the BMS for safe charging limits

@@ReddyToGo. Yes, question was which cars are working with this approach. I expected some communication specialized for the brand of the car. Ok, there is a list. Thank you. Nordkap Vorbereitung, was ist das? 😉

Yes, read more here: github.com/uhi22/pyPLC/blob/master/doc/hardware.md

Good to see you here 👍 love your videos

@ Happy to be here 😃 Thanks ☺️

Tesla needs physical precharge voltage, then it closes the contactors. The test results of different brands are collected in the openinverter forum, subject "Drawing power out of CCS port".

@ReddyToGo. Good to know. Thank you.

@@ReddyToGo. That physical precharge is actually mandated by the CCS standard

The inverter cost me 550€ used, would be 850€ new. The PLC modem is from a consumer PLC bridge and was like 10€. Fuses, power supply, cable, enclosure and CCS plug say 200€. The computer is a BeagleBone green with comms cape and cost another 100€. In my case that was already present. So 760€ of additional hardware in my specific case

Yes absolutely. If this turns out a problem I might wire it up that way.

We got a Ioniq 38 and it close the traction battery relay to charge (via Dc-Dv converter of course) the 12v battery which is a pathetic 40Ah 12v.... It die every 2 years cause of the multiple cycles it does being recharged multiple times a day (at the end of it 2 years life). So clearly in this car and too many EV, they under evaluated he 12v draw.....I'm now doing a specific support to replace the stock 40Ah with a bigger 60Ah.

​@@honumoorea873If you don't experience freezing, but a lifepo4 in there. I have a Porscha 40Ah in my 1.9 TDI during the summer. 😅

Right now, yes, probably. For most cars an additional circuit must be added that actually applies a voltage in the precharge state. Another issue is the long startup sequence of the inverter. It takes like 2 minutes from giving the start command until power delivery or consumption. So this must be cleverly times with the CCS state machine to not run into timeouts on the vehicle side.

@@EngineersFear There must be quicker inverters out there that work? Grid support services need quick response times. Seconds are already a long time.

Thanks :)

Yes on the communication side the project is based on readily available components like a standard homeplug modem. For actual power delivery I would heavily advise on a proper inverter as it is grid connected. They are no that expensive anymore.

basically yes, but: Not all cars will be happy if the charger needs one or two minutes until the current flows. So there will be combinations (of slow "according to the regulation" inverters and picky cars) which will not work so easily.

@@ReddyToGo. Exactly, timing can be critical. I found the inverter runs its startup sequence once it sees sufficient voltage on the battery input. So if that is all prepared it should work

Many thanks!

Hier haben wir einige Autos getestet: openinverter.org/forum/viewtopic.php?t=3551

Das kommt auf das BMS (bzw die Software des Ladecontrollers) an. Manche Fahrzeuge erlauben mehr, andere weniger. Der Touran ist open-source, da geht's natürlich völlig problemlos. Ein paar Erfahrungen mit anderen Fahrzeugen wurden im Forum gesammelt, unter dem Titel "Drawing power out of CCS port"

Not sure I understand right. The 100 kg bike creates a hazard or the 20t truck? The road is marked out as a cycling track because it's otherwise rather quiet

@@EngineersFear Ah, I forgot the #1 maxim of pleasure cyclists--we weigh less so nothing can ever be our fault. Carry on, your recreational activity trumps all other considerations.

@@HanginInSF omg you were serious. It's not the truck being driven irresponsibly but the bike who has the same right to use the road. I forgot the #1 maxim of (pleasure-)motorists: the road belongs to motor vehicles and motor vehicles only. Have you ever wondered what spawns the increasing opposition to cars?

@@HanginInSF you might want to watch this one kzbin.info/www/bejne/Y5CXeI2kfNFoa8U

Again, #motornormativity. It was the cyclists fault that he chose to ride on a road that is also used by motor vehicles. Now you enter your favourite route planner and make me a route from Göteborg to Östersund that does not involve road sharing. Or in fact any 1000 km route anywhere. Then think again whether your comment was worthwhile. I'd rather think motorists who overtake that risky should be prosecuted for attempted murder or something. Maybe that would raise awareness.

@@EngineersFear nope it was not the cyclist fault, but just because you can do something that does not mean you should do it. You can go climb Everest in flip flops and short pants, but you have big chances you will die or at least get frostbite. Truck driver was a douche to overtake him while another car is coming, and if an accident were to happen truck driver would go to jail but the cyclist would most likely be dead.. Is the risk worth it? I don't think so. I used to cycle on roads like this when I was a kid. Now that I am a driver myself I gave up on it and I just do downhill in the woods, or cycle in parks and places where my life is not in the hands of careless drivers.

@@teabaggins3517 Well it would mean I'd have to completely give up on bike packing which isn't going to happen. I'll rather keep fighting even if it's dangerous (handed over the video to the police) Comparing riding on a road that has one car or truck every 5 minutes (should have published the full rather event-less video) with climbing Everest is a bit out of range ;)

@@EngineersFear well, I just hope you stay safe. Enjoy your cycling and I hope you do not encounter anything dangerous again

@@teabaggins3517 Thank you!

Since it's the second scooter with the problem I think it's a general design issue with the BMS. Would indeed be interesting to check in like half a year or so.

@@EngineersFear Ahhh! I thought it was the same one in again for the same fault. My bad!

@@alibro7512 To confuse you even more: it was :) and before that the other scooter.

Thanks. The relationship is linear to some degree. More voltage, more top end torque, more top speed.

For me it is indeed hard to say 😀

It is possible, but I think it's the AMOC not Gulf stream that slows down. Every liter of fossil fuel burned makes live more cumbersome in the long run.

sorry, missed that. I'm currently working on it

@@EngineersFear imho EVERY eCar should have possibility to DC DC charge simply with 10x40V solar panels in series X-D

Enjoy the rest of your adventure.

#motornormativity - it's always the cyclists fault. This is Sykkelroute 9, an official cycling track. It's not like there's many roads to choose from around here

@@EngineersFear I'm not trying to say it's the cyclist's fault, more that it's a government oversight to not supply cyclists with an alternative. But personally I'd simply not drive my bike on the same road as HGVs, it's just a horrible accident waiting to happen. Those accidents are terrible and sad for all involved.

Well in that case it would only be possible to go bikepacking in the Netherlands. One if the few governments that doesn't prioritise cars, cars, cars. Had something happened here I wouldn't even call it an accident. The road was straight-ish and I'm wearing hiviz. Driver must have seen me well in advance and decided it's fine to put my life at risk

Most Norwegian/Swedish drivers slow down and wait until they can pass safely. A douchebag is a douchebag, no matter what road designers do - other than putting the cycle path behind the guard rail
