What the actual fuck⁈ “Batteries can catch on fire.” Sure, whatever could go wrong with a 1000l tank of FUCKING GASOLINE.
AAAaaaaHHhh I hate people!
Going with the “batteries catch on fire argument” is stupid. “Batteries are heavy and expensive” is probably more compelling. But yeah, wires are better solution for things going in fixed routes.
The ammount of water required to put out a normal car is infinitely less than the amount required to put out a battery fire.
Not to mention the extra weight, nor the retention loss per recharge meaning we need to change batteries every 2-4 years polluting a lot more, we ain't even talking about the energy loss when doing the conversion to electric and then again to mechanical.
The electric transport is the way to go in the future, but firts it needs to have a solid foundation, and nuclear is the way to go at least in this moment. Otherwise we are only making things worse.
Edit for those wondering about the battery degradation: https://www.geotab.com/blog/ev-battery-health/
we need to change batteries every 2-4 years
Wait, what‽ No. We don't need to change batteries every 2-4 years. That's what you do with TV remote controls and temperature sensors, not electric car batteries, LOL!
Electric car batteries are made to last at least 7 years (from a warranty standpoint) but in reality it's more like 10. Not only that but they're not single, gigantic objects. They're made of lots of "cells" so if one of them is going bad you can replace just that one bad cell.
Anecdote: The batteries in my Prius lasted 15 years before I had to replace one of the cells. Then a year later I had to replace another one. A year after that I sold it so I have no idea how the batteries are doing right now but I'm sure another cell would probably need to be replaced by now 19 years in service).
I'd also like to point out that the latest electric car batteries are vastly superior to the ones in my Prius.
Yeah, what I've heard is that water cooling the batteries (like almost every EV does now) massively extends the life. Early Prius batteries had no cooling and the heat degraded them faster. 15 years is a pretty good life still.
On the subject of battery warranty:
The federal government requires manufacturers to offer an eight-year/100,000-mile warranty on all EV batteries. California does one better, mandating a warranty of 10 years or 150,000 miles. Some companies will cover a battery only if it completely stops working, while others will replace the battery if it falls below a certain capacity, usually 70% of the original, while still under warranty.
It's important to note, a degraded battery, even with 50% of its original capacity is still useful. Someone who doesn't need the range could drive it, or the battery could be taken apart, and have the cells repurposed or recycled. Lithium and some of the other rare metals used in batteries are quite valuable for recycling, and our abilities to do so are getting better every year.

Sincere question, what happens with the second hand electric vehicle market? New electrics make a ton of sense, but in my mind the 'used car' market becomes essentially unobtainable for poor folk. If a 12 year old electric vehicle hits the market, eventually the second or third owner is going to have to replace the batteries and poor people can't afford the 5000 plus labor to get new cells for it.
This isn't a situation that affects me, at the moment, but there are millions of people around the globe who buy the $1000 car and drive it until it just doesn't go anymore. I don't see that being an option for electrics.
Sincere question, what happens with the second hand electric vehicle market?
Doesn't and won't exist. And it might be a "conspiracy theory" but I do think it is totally intentional.
I didn't mean it literally, but easily it could be considering how u lose performance if u use a battery powered vehicle in somewhere to hot, or to cold.
Also, look how much degradation suffers the battery's https://www.geotab.com/blog/ev-battery-health/
According to Geotab a Tesla will be at 90% of it's initial State of Health (SoH) after 5 years of use while a Leaf (which is well-known for shit thermal management and poor battery quality) will be at 80%. That's worse than their other charts which show averages of 85% SoH in an equivalent amount of time.
Regardless, even operating at 80% after five years is completely fine. The curve isn't really linear anyway so after about 10 years the batteries will likely be operating at about 70% of their original SoH in the worst case scenario.
Also consider that the price of lithium ion batteries has dropped consistently year over year for the past decade. There was a bit of a hiccup because of COVID but that's over now and the price is continuing to drop. That means the cost of a replacement battery pack in 10 years will likely be 60-90% cheaper (if the current trend continues) than it is today.
So? First of all, my platina already has more than 12-13 years and if I lose any performance if I lose any at all, is gonna be maybe, MAYBE %3. And the real matter is all the implications of making those batteries, contamination, and NO FUCKING IMPROVEMENT OVER A NORMAL CAR, in any case it would be worse. What's the point of making ur car battery dependent when the energy used to charge it comes from burning the same fossil fuel as before, but now losing energy in the conversions from one kind of energy to another.
That's without even talking about all the draconian software locks, how companies r starting to lock functions wich already come with the vehicle, how they r trying to kill the right to repair, etc, etc, etc. We don't even know if changing batteries is gonna be allowed or if its gonna be illegal in some way as apple shenanigans already did it in Mexico where its now illegal to even install linux in a computer u already buy it since it would be "alteration without agreement". Want a real change and really helping the planet? we need better public transport and changing how we produce electric energy as a whole, because right now just putting a battery in a car and calling it a day is just additional problems to the already present ones in traditional cars.
Sure, that replacement time isn't 4 but 15-20 years (well, except early Leafs that didn't have battery temperature management of any kind), but my 20 year old car's gas tank fits just as much gas as it did 20 years ago.
If you think any ICE car is going to outlast an electric you're mistaken. EVs have a fraction of the moving parts of an ICE car and as a result are expected to last a lot longer. 30+ years for an electric car isn't out of the question. Especially the latest ones with their water cooled batteries.
The number of moving parts is just one (albeit a great big) factor as to why EVs are a lot more reliable and will last a lot longer than an ICE car. There's other elements as well such as the regenerative braking... You basically have an expiration date that tells you when to replace the brake pads instead of a number of miles (or thickness). Because the brake pads themselves will never wear enough from normal driving to warrant replacement. Instead you have to figure out the replacement time based on exposure to natural radiation (LOL) and seasonal hot/cold cycles.
The magnets in the motors lose about 5% of their strength every 100 years. So again, the thing you're accounting for when figuring out how long the motors will last is the exposure to natural radiation degrading the insulation of the wires (LOL).
I'm aware an ICE car requires more maintenance. But, two things. My gas tank doesn't get smaller over time and good luck taking your Tesla or Chevy Bolt to an unauthorized repair shop and let them try to fix anything without access to OEM diagnostic tools. Yes, new ICE cars are also full of this bullshit, but hey, my 20 year old ICE car isn't!
Good luck finding or affording gas in 20 years!
You'll have to go down to the boat dock to fill up your ICE car because there won't be gas stations anywhere else.
No small thanks to the German government ;)
Just remember that "good" solutions are still preferred over "bad" solutions, and there are never any "perfect" solutions. I see too many people think electric cars are terrible because of what they've been told, like the batteries. For me, it's like "Yeah, but they're still better than ICE vehicles". They'll get better, they're definitely not perfect, but they are just better
YOu can't really stop a lithium ion battery fire, all you can do is keep it from catching other things on fire around it, you pretty much just have to let it burn out.
Which means you need to dunk it in a pool. How many of those does your local FD has? 1-5?
and nuclear is the way to go at least in this moment.
Nuclear is about to go away, looking at the statitics.
Nuclear is about to go away FUCK FUCK FUCK FUCK German government
Frankly, I don't mind as long as I can get enough electricity at any time of the day.
So you don't mind paying 40 cents/kWh?
That would be if we had nuclear only.
Well, there is a push against nuclear and for renewables and prices are going up. Something something ccorrelation causation
I'd be paying that anyway for renewable power given the geography of my country, where nuclear is impossible (ABSOLUTELY impossible). If someone could cut the natural gas from our energy pie and give us clean electricity as a replacement we'd be grateful, given our limited space and relative lack of renewable resources.
And I'm paying that thanks to the German government who made us reliant on cheap and "clean" Soviet natural gas instead of making our own power with our own resources. But hey, shifting emissions to Siberia is easier!
Atomausstieg was plain stupid, agree. But legitimately. I have no idea how my country will survive decarbonisation. We're a tropical island; we have money, but not much else with regard to resources anyway.
Yeah.... not really something I want to see happening.
Ideally solar + nuclear could be the solution we need.
I thought he wanted nuclear energy in cars?
Small nuclear reactor in your car is stupid, but I would love if every city had its own nuclear reactor. Central power and heating!
I'm aware of the Nucleon, that is why I don't want this in my car. But, I would love to have a tiny nuclear reactor in my neighborhood substation or something
Why would I want a ducking bomb under me ? No, I want I city with solar+nuclear power energizing public transport and THEN maybe u could use a battery personal vehicle to move like an autonomous trolleybus.
My problem with "electric" cars right now is where the energy comes from.
Yup batteries are not the way. By the time the batteries need to be replaced you might have helped slightly but probably not. Batteries is a illusion to going green right now. Just another product that has a demand and an easy market for it.
I think we're all aware of the costs associated with recycling batteries.
Are you aware of the costs associated with high CO2 levels?
Have to choose the lesser of two evils.
What would be a better alternative if you exclude the use of fossil fuels?
fixed overhead wires, as OP suggested?
You’re aware that diesel is quite hard to catch on fire
That's why he said gasoline tho
But that’s not relevant for busses
No it's not. It's harder to catch fire than gasoline.
It still catches fire easily.
You can toss a lit match into a puddle of diesel and the match will go out. Diesel burns, but since it doesn't evaporate as fast as gasoline, you don't have those flammable gases hanging in the air. A trail of diesel that's being burned at one end will not spread, unlike gasoline.
Okay
Gasoline doesn't burn that easily, either. Cars with gas tanks don't burst into flames while sitting powered off in a garage. Even when they get wrecked they don't usually burst into flames.
On the other hand, gasoline is slowly causing the world to burst into flames…
Well yeah... You need a spark to cause a fire. To have ignition you need oxygen, fuel and a spark.
Nothing burns easily if there's no spark.
Gasoline burns accidentally when fumes are released, as the stoichiometric mixture has to be pretty specific to combust.
Gasoline in a gas tank does not achieve this mixture. That's the entire job of the fuel pump and throttle in modern cars. As the other user said, there are lots of sparks and live electricity in a car crash, it's just not easy to set gasoline on fire or make it explode.
Diesel does not appear to achieve this vapor mixture readily at standard temp and pressure, like gasoline does, and therefore is technically safer in this specific regard.
Okay.
There are plenty of sparks in a car crash.
Gasoline doesn't burn that easily, either. Cars with gas tanks don't burst into flames while sitting powered off in a garage
Diesel combusts at 140 degrees. A care could reach those temps in a car accident as well if we're making that argument.
Gasoline and diesel can be extinguished relatively easily. Extinguishing an EV means throwing it into a tub of water for a day or two
Gasoline vehicles also don't tend to catch fire spontaneously while parked. That risk exists with every unattended lithium-ion battery undergoing recharging. People technically shouldn't be plugging their phones in at night and then going to sleep, but everyone does it anyway.
Doesn't matter much for phones, but when talking EV charging... Night electricity tends to be cheaper when it's not solar energy season.
Can't wait for miles of 240V extension cords when EU makes even used non EVs illegal. Yes, millions of city dwellers in apartments totally have a garage to charge in.
There will be solutions by 2050 (the proposed timeframe for having a zero-emissions fleet). For an example, vehicles with combustion engines can still be newly registered after 2035 if they use only CO2-neutral fuels. I think EU would rather ban sale of fossil fuels than ban used cars that can technically burn fossil fuels. If only plant-based fuels are available, it doesn't matter what the cars can technically burn.
The German big 3 are already developing cars that would only run on non-fossil fuels I believe.
Secondly, chargers near apartment buildings and on sidewalks can be added. We have plenty of time.
And I'm sure Germany will water down the regulations even more so in the end, I'm fairly sure they'll consider new MHEVs fine after 2035.
And finally, those who can't charge at home will do so at the charging stations. It's not a huge issue if you have a battery with 500+ km of range. Might be an issue for i-miev and first gen Leaf owners though.
Unless we get mass producable, cheap fuel like CHOOH2, "cars can use co2 neutral fuels" is translation to "in reality no ICE cars for the mass population"
Secondly, chargers near apartment buildings and on sidewalks can be added. We have plenty of time.
And who will pay for those? My town can barely get enough money to maintain street lights, who will install and maintain the charging infrastructure on streets where it will inevitably get destroyed?
And finally, those who can’t charge at home will do so at the charging stations.
Oh yes, so now instead of 15 minute wait at a gas station I will only have to wait 2 hours before a space is available and then 30 minutes to charge, all while thinking "how much is this quick charge degrading my battery"
There's 27 years to go till EU's predicted (not required by law) end of ICE cars. There's time to invest, time to innovate and hopefully time for your town to reduce crime and gain more resources.
Also HVO is pretty affordable nowadays. Maybe 20% more than regular diesel fuel at most. It is claimed to be carbon neutral. I'm sure something similar will be developed for otto cycle engines.
Also unless you're planning to use a first gen leaf past the 2050s, quick charging isn't very bad. All modern EVs have battery cooling and will also throttle charging when the temperature rises. The don't full on go 350kW for 20 minutes straight.
Waiting 2 hours is solved by installing more chargers. Clearly a regional issue with fuel pumps as well because I never have to wait over 2-3 minutes.
27? Last time I checked 2025 is 2 years away and 2035 is 12 years away.
crime What crime?
Waiting 2 hours is solved by installing more chargers
Again, how will a town of 25k people that can barely maintain street lights and roads be able to afford 15 thousand chargers?
27? Last time I checked 2025 is 2 years away and 2035 is 12 years away.
It's EU's prediction for when the last ICE cars will be off the road, which was the initial point made - when USED ICE cars are gone.
What crime?
Ia destroying public or private property not a crime over there? You said they were definitely going to be destroyed, I'm assuming you have a high crime rate there.
25k people, 15k chargers
Takes my town of 90k, fewer than 100 fuel pumps to have a nonexistent wait time. Do you think everyone in your town will pick the exact same day and hour to go to the fast charger?
It’s EU’s prediction for when the last ICE cars will be off the road, which was the initial point made - when USED ICE cars are gone. Because of fuel or bans?

I'm Czech. The problem is with a certain group and in todays political climate is unsolvable.
Takes my town of 90k, fewer than 100 fuel pumps to have a nonexistent wait time
Yes, exactly. You need just a few gas stations
Do you think everyone in your town will pick the exact same day and hour to go to the fast charger?
After work? Yes. Again, can't wait for those extension cables hanging from my building's 7th floor
Please don't put lithium in water; that will make it worse.
Tell that to firefighters.
