Overview:

Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

It's completely self proclaimed, but I'm a battery guy and electronics and automotive repair type of guy. Right down to rebuilding my gen 2 Prius battery that now has about 300,000 miles (482,000 km) on it, including when the original battery failed.

You should worry about both of those things if you're buying used.

Prius batteries last so long because they keep a pretty narrow charge\discharge range, despite the total batteries capacity.

But beyond that, the EV batteries in almost all the fully electric vehicles on the road don't have a km used until failure issue. They have an age issue. Lithium batteries have a shelf life, so to speak. It doesn't matter if the battery has 30,000 km on it or 300,000 km. None of them will last beyond 20 years before they start going bad and there's nothing you can do about it.

That being said, LifePO4 are absolutely the most chemically stable and long lasting lithium based battery currently in any EV's. if you're in the market for an older EV with a lithium battery, either plan on replacing the entire battery at some point (check how much it may cost you. Ranges from $6,000 to over $25,000 in some cases) or at least find one that uses LifePO4 as the battery.

Jury is still out on the semi solid state or solid state batteries. Sodium based batteries "should" outlast the vehicle they're in, but there aren't many in production outside of China yet and they aren't as energy dense so will typically be in shorter ranged vehicles.

It totally sucks that everything is littered with hard to get to and expensive to replace electronics they all use. It will be a pain trying to have a classic ev in the future when caps start leaking everywhere and you can't find replacement necessary to function touchscreens.

there's a useful life for ev service, and there's a useful life after ev service. seeing these arrays being recycled for power storage is the way.

that said: good luck getting all the complex shit in an ICE car to last 20 fuckin years lol. something is gonna give. EVs seem complex, but it's far simpler than the array of shit needed to make gas blammo work as motive force for transport.

OMG. So first of all, I literally have two working ice vehicles right now that are over 20 years old.... So lol to how ignorant you are on the subject.

Which also flows right into old EV batteries being used for power storage. A 20 year old EV battery would be absolute dogshit for power storage. Like I said before, it isn't a cycle degradation issue as much as a time issue. The battery chemistry cause cell failure over time. It can't be meaningfully used for energy storage. The cells go BAD.

hey now let's leave the deities out of it....

you literally have two working ice vehicles that are 20 years old and haven't had anything changed / replaced?

like, there's components on both platforms that will need to be replaced eventually. brake pads. hvac coolant. I'd be amazed if your 20yr old ice vehicle had it's original alternator, water pump, etc.,

because the burning focus you're placing on the cells themselves is silly when you think about all the maintenance and repair / replacement an ICE vehicle will require.

[–] ColeSloth@discuss.tchncs.de 0 points 4 days ago (1 children)

Oh no. Not the little cheap repairs.

I do repairs myself. But engine coolant is like every 7 years and costs $40. Brakes are $50 every 5+ years. Fun fact, you're supposed to replace the coolant and may have to replace the coolant pump on EVs as well. They run liquid cooling for the battery and the inverter.

An alternator is typically sub $200 and takes like an hour to replace.

You skipped the most frequent thing. Oil changes.

None of that little stuff at all ads up to the ruining of value cost of a $15,000 battery going bad. I've been driving older vehicles for nearly 30 years. I know the costs pretty damned well. Most EVs are still more of a cost sink for regular people than a small ice vehicle that gets 35+ mpg. Tire changes are less frequent and cheaper. The upfront cost of an EV is more, the resell value is a bigger loss, and you're not saving that much in fuel unless you can charge your ev for free. It's getting pretty close to the tipping point, and it will get there, but it hasn't yet. Not unless you're in a country that gives you access to low cost Chinese made EVs.

lol keep moving the goalposts. your ice vehicle is gonna require way more repairs over it's lifetime, chump.

oh did you forget the point of it all? tho the costs are fucking cheap for each little component, your ice bullshit is going to destroy the ecosystem. goddamn every two minutes you petrol heads have to be reminded that your fucking fetish is killing us all.

GODDAMNIT WHY CAN'T EVERYTHING BE CHEAP LIKE THIS MASS PRODUCED PRODUCT THAT'S BEEN MADE IN THE BILLIONS FOR OVER A HUNDRED YEARS? WHAAAA

you fucking babies are going to kill us all

meanwhile, you know how much I spend to drive an EV 45 miles each way to work? $44, PER MONTH, and it's charged on solar and (if for some reason there's no sun for ages) hydro.

good luck getting that out of an ice car while you choke on the exhaust.

I've literally have over 20 year old vehicles and it literally has not cost me that much at all for any of them. Not even close. You aren't spending $15k on an ice vehicle unless your engine and transmission both need replaced and you're paying someone else to do it.

[–] mojofrododojo@lemmy.world 1 points 3 days ago (1 children)

i get it dude, you don't care lol.

your kids will tho. tsk.

[–] ColeSloth@discuss.tchncs.de 0 points 3 days ago (1 children)

Lol. Go research where emissions contributing to global warming are coming from. This is like the plastic recycling push in the 80s. The government and big corporations are making it sound like it's your fault there's a problem and you could fix it. But that's total bullshit. They're the ones causing the majority of the problem, but they're blaming you for it instead. passenger cars are just a small portion of heat causing pollution.

Ironically enough, making electricity is doing more to polute the earth than ice vehicles. Big corpo keeps burning coal and oil and natural gas to make electricity and the government hasn't done shit about it because $$$.

You want to save the planet, quit worrying about cars and start doing something about actual large scale pollution. Every single passenger vehicle on the planet could switch to electric this year and it's not going help save the planet.

oh ok cars don't pollute bwahahaha you fuckin dolt

WE HAVE SOLAR AND HYDRO, it's not polluting more than your ice vehicle and if you believe so go buy stock in shell and exxon, you're already deep throating their propaganda, you fuckin dolt.

goddamn you really believe you have no impact, how fucking dumb

gonna block you petrol shill, you're in the wrong fucking sub

Thanks for the tip: When buying a used RV it’s how old the batteries are plus how many miles.

And I don’t care that there won’t be “classic EVs” because I haven’t seen one other than the Slate that seems more than an appliance.
