I've never noticed any power drop at low SoC. The car typically warns you of power drop... I've done full power runs up to interstate speed before with only 1-2 miles showing on the Guess-o-Meter and it still went to 120kW on the dash. But anyways I'll try it with the ODBII app next time I get close to depleting the battery. Also that app is a bit strange, it was designed for the Gen 1 Volt. Some of the ODB PIDs are different from the Gen2, so I am wondering about the accuracy on certain things. Though I believe the kW and thus the Volts/Amps to be accurate, as they jive with what the car shows on the dash. I need to get a proper TorquePro template for the Gen2 and use it instead.

Yeah I've lived my whole life within 5-15min drive of the places I work and I'm going to try very hard not to ever change that because it makes everything so much easier. Living in a smallish city helps a lot with that though.

That and the tesla charging network, I suppose I honestly haven’t been in a Bolt yet, just the two generations of Volts. Some people will poo-poo the minimalist design, but its powerful, if nothing else. I didn’t get to drive it, obviously, but it doesn’t seem unnatural thus far. Visibility is excellent, the seats (from what I could tell from a three-five minute stint) were very good, the thing feels solid as hell, with doors that have a really pleasing kerchunk. The door handles feel substantial, it just FEELS right, in most ways. The interior materials are nice, as well. I eyeballed the trim lines and panel gaps, and there wasn’t anything glaringly wrong, though obviously this is the only one currently on display in the South Florida market, so it very might well be a ringer, or have been gone through prior to shipment.

I was driving behind a Bolt the other day and noticed that it still has incandescent turn signals. Maybe taillights too. All-LED lighting seems like a super obvious feature to have on every electric car (both cause it's high-tech and because it saves a noticeable amount of power) and I have no idea why GM didn't do it.

In the Gen2 Volt, every light in the interior are bright daylight white LEDs... EXCEPT for the single inside rear hatch light. It is a tiny, very, very yellow and dim incandescent. And when you have the hatch open, it is so far up in the air, the light barely reaches the rear trunk area at all. The very first thing I did in the first week of owning the car was replace that with a LED. https://www.amazon.com/gp/product/B00NCGFNB0/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 . So if your Volt needs a better trunk light, I can recommend that one. I easily puts out 10 times the amount of light. I really don't understand it... Festoon the entire car with LED lighting, and then skip out on the one light that DOES need to be super bright because of its location.

quote:Also, quality LED headlights are incredibly expensive, hence why GM didn't use them to begin with. The reason they are expensive is due to the fact that many LED bulbs are thrown away from a batch due to inconsistent output and results. I get his point about not retrofitting LEDs but it's kind of bullshit that GM cheaped out on them, they are common on luxury brands and let's not forget the Bolt starts at $38k. I think that is the biggest problem with the Bolt, everything about it screams cheap, it looks like a $12k Chevy shitbox and things like skimping on LED headlights just contributes to that perception.

Charles posted:Why don't they? That's their nature. LEDs are happiest when they're being driven at their design voltage and current, and though you can theoretically dim an LED by turning the current down, that's a relatively complex and expensive piece of electronics to do so, and furthermore for a variety of reasons it's less than ideal (consistency and color, primarily). However, LEDs are really good at turning on and off really quickly, and creating a square wave is super cheap and easy, so that's how LEDs are dimmed. If you drive an LED at full current and voltage but using a square wave that spends 50% of the time on and 50% off, it will look half as bright (roughly, your eyes aren't linear). Easy. Obviously for this to be effective, the drive frequency needs to be fast enough that you can't see it happening. 50Hz or so is fine for a stationary lamp. Something that's moving needs to be driven at more like a few hundred hz to not have the lamps break up into dots. Once you get into the kHz range, no one can tell that it's not continuous. So that's why the manufacturers keep using LEDs that have an inherent flicker to them. Why they don't use high-frequency components that would make the flicker unnoticeable, I have no idea. Probably because they're cheap.

I would think mostly because shielding is expensive. The higher the base frequency of a square wave, the stronger the radio-band harmonics are. And the more shielding you need to put in to pass whatever regulation governs radio noise from cars in the US (or maybe per state? I have no idea, your country is complicated).

Trash Trick posted:this led me to google which led to an interesting discussion about car headlights That is pretty much correct regarding headlights, but what applies to headlights doesn't really apply the same to almost every other light on the car. Headlights need to shoot a lot of light in a carefully controlled beam. HID bulbs in projector assemblies are really good at this. Even properly designed OEM LED headlights or aftermarket retrofit LED projectors don't match the light output of comparable HID assemblies. Even the one vendor selling retrofit LED projectors recommends using their HID projectors instead unless you specifically want LED light. Drop-in "plug-and-play" HID or LED bulbs intended to go where some other kind of light source originally lived are universally bad to use in headlights. Indicator lights on the other hand don't have the same requirements. Basically all you need from them is to cast enough light in roughly all directions so the reflector can spread it further. Optical engineering isn't really critical., so drop-in replacement bulbs work great. There are good reasons to not use LED headlights for now (though this is likely to change as LED tech continues to advance), but there are no good reasons to not use LED indicator lights. They can pack more brightness in to less area and come up to brightness faster, while effectively lasting the life of the car if properly designed. No new or redesigned cars should still be using halogen bulbs in their turn signals. Those that do are cheaping out, end of story.

I'm not super sensitive to flickering light, but a little bit. I don't notice it at all in our lightbulbs at home, we've replaced all incandescents or halogen with LED. Just tried filming in slow motion (96 fps I think it is) as well, where it usually sticks out a lot, and it seems constant. We've specifically purchased non-dimmable, perhaps that makes a difference. You'd think it would be better to switch off individual LEDs in an array rather than dim all of them anyway.

Three Olives posted:GM offers LED headlights on Cadillacs, Consumer Reports even called them the best headlights on the market so they apparently think they are good enough for their highest paying customers. Many makers have been using LED headlights for some time. I know Toyota uses them on some Corolla and Accord models, but usually for lowbeam only. The Gen2 Volts have LED headlights as standard for low beam.. For highbeams it kicks on an additional set of halogens. And I can confirm that on lowbeam they will not melt any ice or snow off. I've had to brush/scrape the ice off a few times over the lowbeam portion. The highbeam side will melt anything off.

Automotive lighting is area that needs a ton of innovation and potential regulation reform. It's silly that your car may have the capability to read road markings to keep you in your lane and have radar to auto set cruise control, but your lighting has two settings that need to be manually toggled with a lower setting that's hobbled to actually limit light throw. I know BMW has an adaptive lighting system, but that poo poo needs to be on more cars as standard safety equipment. Visibility is key to avoiding crashes.

drgitlin posted:You better tell Audi and all the other companies that are using matrix LEDs that they’re morons then. I didn't say there are no reasons to use them nor that they're all bad, I said there are good reasons not to. It's harder to make a good LED headlight because you generally have to have multiple actual sources of light versus one single piece of filament or arc. The ones in the Corolla for example are pretty terrible. The headlight retrofit community jumped all over them when they first showed up because they were cheap and available, but has largely abandoned them because they just don't perform well. CR also calls out the 2018 Audi Q5's low beams as being particularly bad, and I recall hearing some major publication knocking the F-150's as well. What I'm saying is that apples to apples, LED headlights aren't as mature as HID just yet. They will almost certainly be at some point soon and there are already plenty of things that if an automaker wants to do them LEDs are the correct answer, but when we're talking about plain old high/low beam headlights they don't really offer any significant benefits over the less expensive established technology.
