I went to a Tesla showroom a few month ago to confirm that on a model 3, if you open the electric charge port cover it blocks the hatch, which I heard will still open and just snap the charge port cover off. Well that's my story, thanks for reading.

Can confirm that the trunk lid and charge port do not touch each other. I don’t know who started that one, but it’s a nonissue. Source: I just opened and closed both of mine.

Duck and Cover posted:Duck and Covers totally fair review of the bolt and the Model 3. The Bolt is mine, The Model 3 got like 20 minutes drive not on a highway and through road work sooooo not really the best but I have been a passenger in multiple Tesla 3s. Oh did I say the interface is nice? Apparently the tap targets are too small. That's okay though it's not like the touch screen is used for practically everything.

I've always been a bit of an induction nay-sayer, I've just been owned by the Oak Ridge National Laboratory. https://www.ornl.gov/news/ornl-demonstrates-120-kilowatt-wireless-charging-vehicles quote:OAK RIDGE, Tenn., Oct. 19, 2018—Researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated a 120-kilowatt wireless charging system for vehicles—providing six times the power of previous ORNL technology and a big step toward charging times that rival the speed and convenience of a gas station fill-up.

RZA Encryption posted:Wow that's neat. Does it heat the battery pack? Any charging must heat the battery pack, otherwise you will be arrested for violating the laws of physics. But it probably doesn't heat the pack like an induction hob heats a pan. There is an induction (inductive? inductee? inductivated?) loop in the car as well, absorbing the energy and turning into a charge flow.

RZA Encryption posted:I guess I meant "more than plugging it in would" Probably not in a way that makes a big difference. Think how a mobile phone can induction charge without seeing any disturbance on the screen or any problems with WiFi/4G. But 120 kW of anything will heat something, somehow.

RZA Encryption posted:I guess I meant "more than plugging it in would" Shouldn't be any difference.. It's the same amount of power, wired or wireless. Maybe you are thinking of how Qi charging on phones generates a bit of heat? That is mostly down to inefficiency.. Qi charging is at most 60% efficient; a good bit of the energy is wasted in the coils as heat, thus heating up the phone and by extension the battery given that it is often directly in contact with the Qi receiver coil. 97% efficiency on the other hand is probably the same if not better than using a cable and connector, given that connectors can be corroded and vary in resistance.

Yeah, any time you see an efficiency rating, the inefficient portion is energy that's converted into waste energy. Energy can't be destroyed, but it can be converted into stuff we don't want/care about, like heat, noise, or unwanted movement. Presumably most of that 3% inefficiency is heat, with a little going to noise.

How practical it will be to replicate those laboratory results in the real world remains to be seen.

Time for the obligatory "winter stole my efficiency" post, or perhaps more accurately, the heater stole my efficiency. From 115MPGe, to 65 MPGe Why couldn't you have used a heat pump GM? WHY?!?

Ola posted:I've always been a bit of an induction nay-sayer, I've just been owned by the Oak Ridge National Laboratory. At the same time though a practical wireless charging solution would beat the poo poo out of gas stations from a convenience standpoint. At worst a modern EV matches the convenience of fueling an ICE vehicle, if we're counting speed as a separate thing. You go to the place, you open the cover, and you put the handle thing in the hole so fuel can flow. Some of us may be able to refuel an ICE at work, but almost none of us can do it at home. EVs have a massive convenience advantage in that way, if you can charge somewhere you park for long periods of time you may almost never have to actually think about charging or take time out of your day to deal with it beyond 15 seconds hooking and unhooking the vehicle. A practical high-efficiency inductive solution would even eliminate that level of thought from the process. IMO that's what the marketing should focus on, who cares about speed when your vehicle will be parked there for hours?

3.6 kW of heat from the 120 kW is a significant amount of heat. Significantly more than typical engine block and indoor eaters used in cold climates. Nothing that an EV cooling couldn't handle of course, but the cooling probably needs to be active while charging at least.

I'm more interested in a theoretical 7.2KW garage mat version, ~220w of waste at about 20mph for a 3 is much more reasonable in terms of overhead and dissipation. The 120KW+ versions make a lot more sense for transit-- put coils at scheduled bus stops.

I would think the missing 3% went out during the wireless transfer. Although the article doesn't make it clear.

builds character posted:How absurd would it be to put a bunch of them in freeways + roadside solar panels to provide small maintenance charges as you drive? Pretty absurd. I can't imagine that the hardware involved in a high-wattage inductive loop is particularly cheap in terms of cost per square meter covered. Roadside solar panels also are not anywhere near power-dense enough to provide meaningful extra power. If you want to charge while you drive, install a conductive rail in the road and have your car tap into that. But then your "car" is a trolley.

Somehow the fact that almost all cars were RWD up until the late '70s and the roads are full of older BMWs, Porsches, muscle cars, and pickups that get driven year round seems to just slip by them, marketing has them convinced that if they don't have AWD they want FWD.

I thought the exterior was kind of ugly but earlier I saw the interior; it has an asymmetrical dash. The i3 though does have some sweet wheel options. Edit: Oh I didn't make this post clear I think the interior is awful. Duck and Cover fucked around with this message at 17:34 on Oct 23, 2018 |

RZA Encryption posted:You have to add a gas motor to get close with their current configurations, right? It's a little weird when it runs, because it'll poop out 5 miles of range or so then go quiet, then ramp up again when your range gets pretty low. Plus, there's a major limit to how much it can produce, so you're hosed if you're going up a hill or need to maintain your 75mph cruising speed. VvV It's not an electrical issue. It's literally designed as a battery charger to get you to the next plug-in point. Which, to be fair, is not exactly a point made obvious by BMW.
