In April, a group of people in a red Tesla driving through the Moroccan desert were glued to the odometer on the car’s giant touch screen. “Two million, Hans! Two million,” exclaimed the front-seat passenger to the owner and driver, Hansjörg von Gemmingen-Hornberg.
Ah, it's gonna be one of those fluffy wanker articles.
Good luck with that. Planned obsolescence is a key ingredient in capitalism. I mean what better way to make line go up than to turn a one-time purchase into a repeat purchase? This shareholders and executives will never be able to step on the working class if they can't gouge customers. Won't anyone think of the shareholders?
power density just needs to grow until someone can easily kit-swap a range of battery and motor options into any platform - then we can ev-ify whatever we want to drive around.
It would be wonder if they last forever and easly could be repaired. Making it better to keep the car then buy a new one. It just need to be upgradedable to the latest standards that might be more safe, efficient and agree with current law.
But I am pretty that would never exist - too hard.
There's not much room for improvement in terms of efficiency for EVs, except maybe lower rolling resistance tyres and better aero. You generally have to replace the whole car for better aero though unless you don't mind having some bolt on mods 😂
Ok, but it might be in other areas. Example lets see someone invent very high efficiently on solar panels with no weight at all. Or lets get rid of rubber wheels and do sifi so the car can hover over the road.
I think people need to start being educated about how their climate influences how they can use the electric car. Many people know if they live by the sea or where roads are salted that corrosion is an issue. But people might not be aware that with some EVs, they should leave it plugged in if they're in an extreme climate, so the car can air condition or heat the battery. I caused some battery degradation to my Volt because I wasn't able to leave it plugged in living in Tucson.
That is too general of a statement. I have three EVs in my family, none of them do any temp condition of the battery just by being plugged in. However, EVCC turns off the wallbox when they reach 75% SoC and there is no appointment that day in our shared calendar. Sitting at high SoCs kills batteries, especially in warm climates.
You have a point; some EVs like the Leaf don't even have conditioning. The Volt does have active conditioning, and being a PHEV instead of a BEV has battery charge and discharge limits which were limited by the factory to preserve longevity at the expense of being able to charge to a true 100%. If extra range is needed the ICE is activated instead of stressing the traction battery.
Yeah I've only ever had one LED bulb die, and I think that was because it was faulty in some way. I've had a much better experience with them compared to CFLs.
Usually it's a badly designed heat sink that's meant to cause an eventual short so that it has to be replaced. Or just shoddy low material builds. LEDs really can last an obscene amount of time and they don't die another part does.
Most LEDs run on DC, and the built-in transformer is the most likely component to fail. If the LED is failing and getting dimmer, it's most likely due to poor heat dissipation.
If we had little 12v adapters and separate LED modules, you could reduce waste by only replacing the part that fails, and manufacturers would have greater incentive to improve build quality. Instead, we get cheaply manufactured bulb-shaped disposable units that need to be thrown away when one part fails.
I was looking at rv lighting as some options over wise just doing custom jobs (LEDs in whatever fixtures I think look nice). It helps like domes, reccesed, and ambiant lighting I think.
Oh yeah electricians are allergic to DC lol (I used to be one, and yeah that was big knowledge gap in codes, breakers, etc).
Electricians don't want to touch DC circuits because it is illegal to mix low voltage DC and high voltage AC circuits. At least it's illegal in Europe. You need to rebuild your walls to ensure separate and independent wiring channels. And that's a very expensive nightmare.
Yeah, I definitely get it. It would be illegal to mix low and line voltage in the USA, too.
I ended up running the cabling myself, all class two circuits powering 12 24vdc spots. The nice bit is that they are all addressable RGBW spots, so I can control them all individually or as groups. And it's all automated. The downside is that I'll probably have to remove them if we ever sell this house, because nobody but me understands how it works.
The thing is that it is a lot easier and a lot safer to buy some ESP32 boards, flash them with WLED, plug into 5V/12V/24V box, hide all of that in a 3D printed enclosure and call it a day than to rebuild the bloody walls (: And you won't be breaking any regulations and every sparky will be fine with that.
Running all your house with two wiring systems is dumb AF that's why no one will ever do that for you. That's my point.
I used to work for a European home automation company. Thing is, their gear is most cost effective in new construction and was very popular in Germany, Austria, Czechia, and Poland, but convincing anyone to wire for low voltage devices in the UK or US was like asking for ketchup on pancakes. There are a lot of reasons to like their tech, but they don't really do retrofit, so it hasn'tanaged to make a dent in the market.
Yeah. Its about 50/50 for the ones who failed me. Gets too hot and burn out or the power supply fails. More prevalent in the compact formats like spots and g8 or g4.
LEDs themselves don't get dimmer and don't fail. Their drivers fail and run LEDs at higher voltages so then LEDs burn out. If the LED is driven correctly, it won't dim over time and will last pretty much forever in terms of human lifescales.
“Unlike gas-powered engines—which are made up of thousands of parts that shift against one other—a typical EV has only a few dozen moving parts. That means lessdamage and maintenance, making it easier and cheaper to keep a car on the road well past the approximately 200,000-mile average lifespan of a gas-powered vehicle. And EVs are only getting better. “There are certain technologies that are coming down the pipeline that will get us toward that million-mile EV,” Scott Moura, a civil and environmental engineer at UC Berkeley, told me. That many miles would cover the average American driver for 74 years. The first EV you buy could be the last car you ever need to purchase.“
No way a car would last me and my family 74 years. First year I owned my car I put on almost 35k. Was driving 100 miles back and forth to work at that time. We typically take a road trip from colorado to near Vermont every year for a vacation.
A lot of midwesterns will drive 14 hours to get some where
In the San Francisco Bay Area, it's not uncommon for people that work here but can't afford to live here to have commutes of over an hour with good traffic (2+ hours with heavy traffic) each way. That's the case in a few major metro areas in countries like the USA and Australia.
My commute in the Bay Area is 15-20 mins without traffic, but it can be 50 minutes if there's some incident on the 101 or if I accidentally try to commute during the highest peak period.
I'd love to take a train to work, and I used to take Caltrain every day, but it's just not feasible where I live now.
Round trip was 100 miles every day. This was rural Ohio driving to Columbus so it was not to bad 2 and 4 lane roads till you hit the city most of them time. If we got a lot of snowfall it could super suck but I was from NE Ohio so most of the time it was not that much white knuckle driving. You just listen to a lot of audiobooks and podcasts or call some friends on your hour or so drive home
Sure, there's always going to be outliers. Most people live and work in the same metropolitan area though - they're not driving 50,000km+ a year.
Besides, having a vehicle with 5 times the effective lifetime is going to be a big win regardless of how much you drive it.
Last nearly forever? That needs to be broken down into details. Aren't batteries for EV limited to about 10 years of use? And they're a costly replacement?
A good solution would be to make EV batteries easily swappable instead of "charge stations"...
There's a couple thousand in China for Nio, but they haven't really taken off anywhere else.
By contrast there's over 1.8 million public EV chargers in China alone.
Batteries are heavy, which makes them hard to move and requires secure attachment to the vehicle. EV chargers have no moving parts and require much less maintenance.
I think we will stick with built-in batteries rather than any kind of swapping. I always thought the battery swapping idea was neat, but the real world cares about money more than anything.
To have ubiquitous battery swapping stations would be a huge amount of infrastructure. But to have ubiquitous vehicle charging you basically just have to run wires to existing parking spots.
That is combined with the fact that I think batteries, especially LFP batteries, have a lot more cycles in their lifetime than your 10 year estimate would suggest. I’ve read 4000 cycles for LFP in a few places. That’s more than a decade even if you fully charge and discharge the battery every single day. Drive a more realistic number of miles/kms per day and then the chronological age of the battery might be more important than how many cycles are on it.
Electric motors can last a really long time, assuming no defects, they should outlast the battery by a Longshot.
That leaves the battery, and an LFP battery should also last a hell of a long time, probably a decent way into a million km before you have degraded to about 80%.
If you got those key items lasting, then it just depends on how well the rest of the car holds up, but replacing small parts while the motors and battery works is probably always going to be more cost effective.
The problem is the battery is a wildcard still.
We know how long those LFP batteries should last in a car, but they're also pretty are in cars and we don't have that real world data yet.
I also fear that OEMs will still gouge us on replacement batteries 15 - 20 years from now when costs are even lower and replacing the battery shouldn't be so expensive.
The battery doesn't have to fail for the car to be useless. One of those circuit boards that holds it all together goes and it's "whoops, we don't make that any more".
I had already read of the first teslas model S getting to 1M km with ordinary maintenance alone, so it should be pretty easy to achieve. Of course it won't be done as it wouldn't be profitable.
