I've just read through this whole thread. I have a few comments, then a question....
After installation I was able to charge with my Wall Connector, so I went to the grocery store where Francis Energy has four 50kW chargers. I tried each one, but kept getting the message DISPENSER_OVERCURRENT_ERROR on the charger. I went to another Francis location and tried both of the 50kW chargers there and got the same error.
There's a YouTuber called
Crazypostman who did a series of videos about a year ago with the Setec CCS adapter, mostly on Francis Energy fast chargers, and IIRC he ran into that error on some of their units. I can't reference a specific video right now, but you might be able to dig a bit to find them. If I'm remembering correctly, then, this may be a problem with some Francis Energy units generally.
I thought the 2022s come saying CCS1 enabled?
A friend of mine bought a Model Y about two weeks ago, and his came with CCS enabled. (I was with him for the delivery, and we checked this detail.) Of course, as others have said, YMMV....
Have you found a good website or data resource that shows how your/our battery degradation means and averages? I read online blogs from Teslarati and other online sites of "2-3%" degradation over 50k or 100k miles, so I've been a bit disappointed that I may only have a 65-68kWh capacity left, though I do admit that most of my charging has been done with Supercharger or CHAdeMO fast charging, rather than L2 or L1 charging. However, after my first year of ownership, I was quite good about keeping my car between 20-80% when not regularly driving, though I wonder if my regular driving of 400-500 miles (95-100% down to 15-20% twice a weekend) every other weekend for 3 years caused some of the quicker degradation.
I've subscribed to TeslaFi since a few days after taking delivery of my new LR RWD Model 3 in March of 2019. I'm currently at 27,230 miles with a current range of 301 miles (down from 325), vs. a fleet average of 300 miles (for cars with similar odometer readings). Thus, both my and the fleet average degradation over 3+ years and ~27,000 miles is a bit over 7%. This makes me think that 2-3% degradation over that, or longer, periods is a rarity, not the typical amount. That said, it could be that forcing the BMS to fully recompute everything by doing a deep discharge followed by a 100% charge would improve TeslaFi's report for my car, and for the TeslaFi average, too.
My question:
The Bundle of Wires that makes a Gen4 ECU work with a Gen3 ECU actually discards the port-heating pins - they go nowhere, but the ECU thinks there's a heater there. The problem is, there's no hardware in the port that could "heat", so there's nothing to connect to. The ECU also always thinks the port is hotter than it is (due to the thermistor issue, "patched" to a safety-functional degree with those resistors), so if it's 10F outside, it probably thinks the port is sitting happy at 60f. It wouldn't heat properly even if it could.
How would this impact those of us in cold-weather areas? I live in Rhode Island, and both park and charge outside -- my house has no garage, but I do have a driveway and an outdoor EVSE. I know that Tesla implemented a hack of unlocking the charge port in freezing weather to keep it from freezing shut, prior to adding the heating feature to the Gen4 charge port. Do you know if Tesla's unlocked-port hack relies on the charge port's thermistor reading, or is it based on some other temperature data? If the former, then I'm guessing that adding the Gen4 ECU and the Bundle of Wires, which reads 60F in 10F weather, would tend to cause Tesla's cold-weather workaround to fail. Do you concur? This might not be a complete deal-breaker for me, but it would be a serious drawback. (I could be careful about charging in particularly cold weather to compensate.)
Also, if it
did get cold enough (presumably sub-0F weather) to trigger the port heater, what would happen? Would the car detect the absence of a heating element and throw an error, or would it just ignore the absence of the heating element?
Oh, and just FWIW, I took my car to the Warwick RI SC today for routine maintenance (tire rotation, etc.), and I asked about the availability of Tesla's official CCS update. The woman I asked (the service manager, I think) said she didn't know. She also said that I'd be notified when it became available, but I don't believe that for a moment. I'm not even sure she knew what "CCS" meant, and was just saying what she thought I wanted to hear.
