What are the Bonn hive mind thoughts on the Nissan Ariya? I get the feeling that other AI threads seem to consider Nissan a borderline predatory lending manufacturer. The early preproduction models of the Ariya do look kinda nice. If even half the stuff the YouTube reviewers are showing make it to production, I think there might be something to that vehicle. The haptic integrated buttons in the dash and center console do look pretty nice. I wonder if they provide any real savings over physical buttons. The extra space in the front row has the potential to be nice for my giant frame as well.

I watched the video Bjorn Nyland (Tesla Bjorn) did yesterday or so. It looks nice? Without pricing and all the stats it's hard to say how competitive it will be. People generally like their Leafs though, right?

Looks decent, I’m sure it’ll have proper battery management now and Nissan has more ev experience than anyone really. Should be a good car. Piano black plastic on the outside is a seriously bad idea though, hopefully it was just a pre production thing.

One of the videos I watched mentioned that the batteries were liquid cooled, and were supposedly going to be capable of 130kW DC charging in either size pack. And that they were going to the CCS port standard in the US.

They'll probably except EV chargers, but it would be awesome if instead they had an attendant in a 40cal suit sitting by the chargers to connect and disconnect you. Now that I think about it, the way current DCFC probably gets around any high volt safety requirements is that the chargers don't put out high voltage until they're properly connected. Speaking of, Hey DoomTrainPhD, what do the DC fast chargers look like inside? Is it a transformer connected to a full-wave bridge rectifier, or is it an IGBT/inductor assembly that boosts voltage while rectifying it? Is there any reason chargers couldn't be connected to distribution level voltage and then use IGBTs in a buck configuration? Seems like that would save some copper at least.

Also sorta on topic, I got recommended a YouTube video on a company called Witricity claiming 91-93% wireless charging efficiency using a form of resonant inductive coupling. Reading Wikipedia, they weren't even able to successfully market a laptop charger, so I'm calling total BS. Still, would be cool if I'm wrong.

Wireless charging makes a fair amount of sense for small electronics, a couple watts lost due to the lower efficiency is barely worth noting. You'll pick up and put your phone back down numerous times per day, always plugging it in would be annoying. A car uses way more power, so the efficiency losses are more salient, buying an expensive device plus paying an extra 5 to 10% to charge your car vs just plugging it in once or twice a day, seems like a hard sell.

I remember seeing something about having induction coils under highway segments to allow for at speed charging, that must be hilariously inefficient. So no wonder it was just fringe-y.

So no wonder it was just fringe-y. It's not the same technology as standard induction charging, because both coils resonate, so it's hypothetically way more efficient, if true. https://en.wikipedia.org/wiki/Resonant_inductive_coupling Somebody smart at physics can interpret that. https://en.wikipedia.org/wiki/WiTricity Here's their Wikipedia article. They made one wireless charging adapter for a Dell laptop in 2017 and that's it. I can't even find any reviews for it. I don't even know if they sold it.

I hadn't seen this posted here yet: https://www.autoevolution.com/news/aem-ev-delivers-more-power-to-tesla-ev-conversions-with-its-new-control-system-155435.html Stand-alone controller for the large Tesla drive units that bump power up 26% vs the stock unit. As if I needed more of a reason to dream about EV swapping a 1960's Buick. It is impressive that there was that much power left on the table.

Is it a transformer connected to a full-wave bridge rectifier, or is it an IGBT/inductor assembly that boosts voltage while rectifying it? DC fast chargers (DCFC's) don't look like much on the inside other than some fans, pumps, networking wires, and a controller board. DCFC's really aren't "chargers" so much as passthroughs. All the real power comes from the Power cabinet units (PCUs) and power electronic modules (PEMs). The DCFC itself talks to the PCU which in turn talks to the PEM. The PEM itself will say "Oy, you want ${requested_voltage} and I have ${actual_voltage} so that's what you are getting."

I followed a Model S along the autoroute that runs along the east end of lake Geneva last night. It seemed to be having difficulty staying centred in the lane and was braking quite sharply at the speed limit changes. It is a pretty twisty bit of motorway, but is that the Autopilot experience? Could of course just been a lovely Swiss driver but either way I wouldn't have enjoyed being a passenger. Luckily Porsche Innodrive is sufficiently bad that I am not tempted to use its more advanced features, but the lane keeping at least is solid. It's a nice autoroute as they go.

How's the road markings and lighting? bad road marking can induce some unpleasantness with autopilot, but otherwise it should be pretty solid. In my experience it doesn't brake very hard at speed limit changes either. It's impossible to know for sure if the car was on autopilot or not without looking at the dash though MrOnBicycle posted:Didn't Model S motors burn out frequently? At least on the older models. The early drive units failed a lot due to design/manufacturing flaws, but the newer drive units are good as far as I know.

Apparently my heat pump on my Soul EV doesn't work due to a faulty software update. I didn't even realize because I bought the car used. On reflection, it should be obvious because a compressor is pretty loud. :facepalm: From what I can find dealers and even corporate are totally clueless about this and don't know the difference between the resistive heater and a heat pump. Fortunately there's news from Norwegian owners of a fix on the way.

A lot of the Model Ys and 2021 Model 3s have been experiencing software and sensor issues with the heat pump as well. I used to be a bit jealous I missed the cutoff for the Model 3 heat pump but now I'm ok with it after reading about all of the issues online. My Model 3 was basically flawless, gaps and all. Apparently the ID4s coming to Canada will have heat pumps too, though oddly the US specific variant will not.
