The motors have never been the problem, it’s always been the battery. See train engines, they are a diesel generator with electric motors.

This is where history pisses me off. We should have been headlong into battery research after the oil embargoes. Could have been 40 years faster.

Um piss off. It is not irrelevant or misinformation. That is exactly what petroleum is.

You clearly can’t understand a factual statement from an opinion I never said it was good I never said it was bad I just said it was. If you’d bother to take a moment to think about it. You would realize that I was referring to the fact that petroleum is extremely energy dense. For the very reason I stated. That is fundamentally why petroleum has become a successful energy source and why it’s been so difficult to replace.

You’re welcome to point out where I said it was renewable. I think you’re going to have a difficult time finding that statement.

Oil is honestly an amazing product, chemistry wise there is so much we can do with it and energy wise it’s a extremely concentrated and easily transported form of energy.

Energy wise one liter of oil is equivalent to 10 person working for a day !

I repeat, using one liter of oil is like having 10 “slaves” working for us for a day.

Its easy to see why oil became the base of our modern civilization, and easy to see why we don’t manage to stop using it even though it’s destroying us.

Yes, but no one’s even glancing at it for use in vehicles. The one that’s finally getting into production is 70wh/Kg. Not nearly energy dense enough yet for ev’s. Lithium batteries are closer to 300wh/Kg. In other words, they take up 1/4th the space and weight. EV’s are already a thousand pounds heavier than non ev’s and that’s already causing extra tire pollution issues and having to overbuild suspension parts and bearings. Making them another 3,000 pounds heavier than that is just out of the question. Let alone making the space to fit the battery.

Sodium is going to change the world with its power storage capabilities connected to solar. Anyone on like 75% of the planet could 100% live off the electric grid problem free with enough solar panels and a big sodium storage battery.

Exactly this. Imagine if gas powered motor could recharge in mere 12 hours and run for up to half the distance. Ah, that would be the dream.

And if you and 5 of your neighbors decide to refuel at the same time during peak hours you have a real chance of overloading your neighborhood grid. And your fuel tank is dead in 5 years, replacing which is more than half of your used cars cost.

Everything non-portable uses electric motors from the time the first wire was invented.

https://www.cnbc.com/2023/07/01/why-the-ev-boom-could-put-a-major-strain-on-our-power-grid.html You can read cnbcs article on how the grid is already pretty spread thinn with us already increasing our power demand by almost 3,000% in the last decade without even considering ev charging

https://www.motortrend.com/features/how-long-does-it-take-to-charge-an-ev/

According to motor trend DC charging is the fastest way to charge your EV and it still takes just under two hours Couldn’t find a source that studied how long a ice takes to recharge but considering how ices are currently extremely common you can easily test that yourself and probably already know it’s so quick you don’t even think about it

According to car and driver those lithium ion batteries you mentioned while yes they can last a decade most cars typically stay on the road for give or take 30-35 years and lithium ion batteries are inherently expensive and prone to thermal cascading ie catching fire also full charge and depletion wears the battery down over time

It’s exactly this. Convenience. We’ve become accustomed to how convenient it is and don’t want to be put out.

On the other hand, it’s super convenient to never go to a gas station again, and to wake up to a full tank. So if you drive less than 60 miles a day, and have acess to another car for long trips, an electric is even more convenient.

It’s one of those things where people feel like they’re going to take a road trip every weekend, but most people are just using their car to commute to and from work and maybe take one or two longer trips per year. The time saved by not having to stop at a gas station throughout the the year is less than the additional time taken at a fast charging station for the rare road trip.

All EVs come with Level 1 chargers that plug in to your standard house outlet, NEMA 5-15R. If there’s an outlet nearby you can charge your car.

Are those two things actually important?

Electric motors are a lot more efficient, and battery technology is quickly approaching the place where you can get the same range with an electric motor as with an ICE.

As for refuel rate, I spend no time waiting for my car to charge because it charges at home while I’m sleeping, so the refuel rate doesn’t matter.

Plus the technology to battery swap is well in use for electric vehicles (see Nio, who have thousands of battery swap stations in China and some in Europe too). 3 mins and you have a full battery.

Although own an electric car, I believe range is still an issue. I was specifically addressing fuel density and charging time. EVs have their issues, but I believe they will be solved over time even though they are unlikely to beat an ICE in fuel density or charge rate for a long time. But I don’t think those things are actually important, because the problem is solved in a different way.

Yes, for people who can’t charge at home. I’d love to swap to electric, but 1 hour trip to go charge the car at the nearest charging station is not realistic - especially since I’d need to do it twice as often as 10min trip to refuel.

Also there’s the EV prices, starting at 2-3 times more than my current whip lol

My point is that we should be focused on the outcomes we want. It isn’t really important that fossil fuels are a lot more energy dense if the electric cars can travel twice as far. They can’t, but I’d be willing to bet we will get to that point with fossil fuels still being more energy dense.

But also as I mentioned in the comment you relied to, Nio have a vast network of battery swap stations where you can get a full charge in a couple of minutes, the same as filling up at a gas station.

The price of EVs are a problem, and not the only problem, but my point was that the specific things mentioned don’t stop us having better EVs than ICEs, because we will get the same outcome in a different way.

i doubt we even have enough rare metals for 8 or 16 billion batteries. most of them are being mined in politically unstable or to western civilization unfriendly countries, with terrible effect on the environment.

efficiency matters, it is not a question of how good single battery is.

As for refuel rate, I spend no time waiting for my car to charge because it charges at home while I’m sleeping, so the refuel rate doesn’t matter.

Hey mate I’m just here for some friendly discussion, I’m not here to argue until I’m blue in the face.

There is a difference between your above points and the original claim.

Fuel density doesn’t matter, what matters is how far you can drive on a charge.

Charge time doesn’t matter if you can swap a battery in 3 minutes instead of waiting to charge.

For your new point of rare earth materials, this isn’t related to the original energy density or charge time points, but high density batteries that don’t use rare earth metals already exist, the problem is cost. That will change over time.

Also you’re ignoring that fossil fuels are also dug out of the ground.

Dude…

Norway is incredibly sparsely populated and has an adoption rate of 80%+. We also have stupid cold winters, loads of fucking mountains and require AC in summer.

Your comment makes me think you have no experience with EV’s at all and are spreding false claims.

There are literally two scenarios where an EV is not better than ICE (if purchased new today).

One is for people frequently traveling far beyond the cars range and the other is for people without access to AC charging at all.

And no, I’m not a EV lover/gasoline hater. I ride a motorcycle powered by dinosaur juice too. I just like having 400+ BHP and 700 Nm of torque in a car priced like a Toyota Avensis, and a full tank every single time I leave my driveway with said full tank costing me <$5.

If you don’t drive for work–and I mean get paid to drive hundreds of miles every day, not just a long commute–or take a road trip every month, and have a place to charge at night (most people do, at least in North America), then an EV is just better.

Otherwise, a plug-in hybrid or a “gasoline boosted EV” like a Volt is sufficient. ICE cars for regular people shouldn’t have even existed once the Volt proof of concept was proven!

Real answer: power density. Pound for pound, gas still contains more energy than our best batteries.

Googling tells me that:

  • Electric cars have 77% efficiency
  • Gas cars have 30% efficiency
  • Electric car batteries have 270 Wh/kg (converts to 0.97 MJ/kg)
  • Gasoline has 46 MJ/kg

So the math here says electric gives you (0.97 * 77%) 0.75 MJ/kg output and gas gives you (46 * 30%) 13.8 MJ/kg output. Plus, as someone else said, spent gasoline no longer weighs you down.

And let’s not forget that fueling your car requires a tank, a decently sized pump and 2 minutes of your time. A quick charge will hopefully charge your battery to 80% in 30 minutes, while giving you less km and running 300kW of power through hefty cables and big transformers, consuming the amount of energy that a family house consumes in a few days.

(And yes, battery manufacturing and disposal consume enormous amount of resources)

Electric and gas have different situations in which they shine. Gas/diesel engines are just a bunch of steel and some control chips, optimized in more thana century of technological development if we couls develop carbon neutral fuel, electric cars would not be needed. Unfortunately, it woulf be difficult to do at scale of current fuel consumption. More (electric, battery-less) public transport, less road goods transportation, more nuclear, electric for vehicles that move 100% of the time (delivery and logistic vehicles) and carbon-free fuel for other kinds of vehicles (personal transportation) is a good balance, in my personal, ignorant, armchair opinion.
