Found the problem. The maximum voltage was sent wrong based on the configured value 270V. We fixed the code to send the value gotten from chademo and it charges now as proven by a multi minute test session. There are some remaining questions about how to handle the maximums reported by the charger.

I can imagine one option would be to get a batch made of some sort of compact carrier boards without the mcu or anything "extra", to concentrate supply issues to an otherwise trivial board, and then more leisurely develop mcu+i/o boards that can utilize it without any other hard to find pa...

The Leaf motor is a permanent magnet motor though. I don't think the magnets can handle 170°C.

What do you think is a reasonable maximum temperature for the motor? In the Previa, I have have the battery and motor/inverter coolant loops running in parallel through the big original radiator. The problem then becomes in high speed summer driving (e.g. 120km/h uphill at >25°C) that the motor star...

Is the QCA700x available for purchase in small batch quantities?

It seems to me NACS is basically CCS2 with a different physical connector, so that's not an issue. However you bring a good point about payments. I hope Tesla activates payment via app for all EVs in the US like it has done in Europe. While Europe is better positioned for this as Tesla uses CCS2 her...

Apeldoorn was the only Tesla Supercharger site that didn't work, out of probably more than 20 so far. We switched to a Tritium Veefil PK by Shell there nearby.

You sometimes have to switch stalls on Superchargers though, due to melted plugs or otherwise inoperable stalls.

After more than 3000km of driving, we have reached the alps.

Long story short: I was planning a road trip around central Europe with the Omega, but just in the final days before the trip it started acting up and killing vital components, so I set up CCS in the Previa instead, got new tyres and the paperwork and set it up as a mini camper all in like 2 days an...

2023-05-14_150855_circontrol_r.zip - Circontrol 50kW CCS+Chademo combo unit works now. 2023-05-14_15_delta_r.zip - This is a 100kW Delta charger (Delta SLIM 100 seems to match what it looked like) - It communicates but wouldn't start charging - It is a dual CCS unit and I tried both CCS plugs - Inf...

It might make sense to just use paths relative to the script file location. Do this at the beginning of the script: dir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" And then just use paths like "$dir"/log/$date"_pevNoGui.log Then the paths ...

As always, when you add Tesla to the equation you start asking whether the others are even trying. I really like the combo of Tesla + an open standard.

Yes I did. The procedure you should follow is: - Pick a "katsastusasema". Preferably one that is popular with car enthusiasts. - Ask them for list of things that need to be done, rules to be followed and things that will be checked - Remember to follow the axle mass and power limitations o...

2023-05-12_152_kempower_m.zip - The original Kempower - On the first attempt charging didn't start, but on the second attempt it charged fine. I wonder what the issue was on the first attempt, haven't had time to look yet. 2023-05-12_163352_tesla_k.zip - Multi-minute Tesla V2 Supercharger session. ...

Shows my crappy SoC calculation a bit too well! I have some fixes to it underway. I don't have much time for focusing on that now though. Anyway, graphs are nice.

A spring CCS photo with the summer wheels and new tyres. My tyre choice was a mid priced fuel economy focused one: Hankook Ventus Prime 3. I like them so far. Not sponsored.

The final log for the day. It is a 1020 second log, of a succesful charging session, where no DHCP requests can be found. I think I'm set for a new attempt at the Tesla Supercharger. That'll be for another day though. Overall this is definitely the smarter method to this. Always test changes on this...

On the Kempower now. I confirm that uhi's commit and johu's NetworkManager config example seem to be working. [EDIT: No, turns out I didn't have uhi's latest commit in use here yet...] I need to look at the pcap file and see if any DHCP requests are going on now. If I don't see any, I need to go to ...

Did a long test run today. It was miserable. Nothing worked. I'll try to describe the events, attach the logs and hopefully we can draw some conclusions. I will be marking chargers for my own reference using letters inside []. You will not find a single EXI message being received by pyPLC in any of ...

Ah yes. I might not have added eth0 to the ignore list of networkmanager, that's definitely a possible source of problems. Why isn't the problem occurring on other chargers though? EDIT: Or I guess maybe it does occur, but the timings are a bit different and/or the other chargers look a bit differen...

I agree the most interesting thing surely is going to be how you're going to fit the model 3 modules both in terms of space and also in terms of weight. They're 2 meters long and weigh about 400kg total.

Not able to check right now, but I suppose the OS is Armbian 23.02. Recent bog-standard Linux. I do wonder if there are any kernel parameters to play with. Does the car send the ack to one of the attempts but not the rest? Some sort of ack rate limiting or something? I'm not experienced with network...

Here are the logs as described in the previous post. EDIT: I think I have a 4.7 nF capacitor and no series resistor. Good enough? Well... I suppose kind of, but I'll swap something closer to the spec. EDIT: Swapped in a 220 ohm series resistor and a 1nF capacitor that looks like it's about 50 years ...

Quick news: I literally just extended the stateWaitForCurrentDemandResponse timeout and V2 Supercharger works perfectly now. Looks like it simply transitions into a slower update interval after some time of charging. Anyone know the required intervals by the standard? Eh... Well, not so fast. It abr...
