You don't need a 100kWh pack. Most of the smaller cars are closer to 60.
If you’re comparing an ICE vehicle that can get 400 miles a tank to an EV then you are being completely disingenuous to compare it to an EV that only gets 100-150 miles of range. They’re not comparable. An EV that gets even close to the same range is going to way much much more than a comparable ICE vehicle.
If you got 400 miles on a 100kWh pack you'll be getting 300 on a 60kWh pack.
It completely depends on your drive configuration and aerodynamic efficiency rating. Also I don’t know why you think I said anything about getting 400 miles on a 100kWh pack. This conversation is about weight. You don’t just get to say “get a smaller battery pack and then the cars weight the same” because it makes them completely different cars. The average ICE vehicle (of the top25 sold) gets 460 miles of range. https://insideevs.com/features/527446/electric-cars-range-equilibrium/ (funny enough this article is literally what we’re arguing about!)
In any case, I’m not even arguing for larger batteries! I’m just stating that you can’t compare weight if you aren’t going to compare range. They go hand in hand.
2w old conversation, but what I was trying to say is that 100-150 miles (your example) isn't the alternative to 400 miles in an EV (which will absolutely require a 100kWh pack). As you reduce the range through a smaller battery you get some range back through reduced weight.
No it's not? 400 miles of range is completely unnecessary.
400 miles of range is 5 hours of driving (plus enough reserve to comfortably skip a busy, broken, blocked, or skeevy recharging point), recharge over lunch, and another 5 hours of driving. 400 mile range is where road trips become feasible.
400 miles of range, in the mountains, is 150 miles of range.
My ice has less range than 400 so this is a bit of an exaggeration.
ICEs can refuel during a bathroom break. EVs need a long lunch. Turning every bathroom break into a long lunch makes a 3-day trip into a 5-day trip.
I mean it’s not, we have two ICE vehicles with 400 miles of range, and one EV with 265 miles of range.
Weird, because I just did a several thousand mile road trip through the mountains last month with half that range.
And I can put in a leather gimp suit and have my partner spank me with a ping pong paddle. You don't shame me for my masochistic kinks, and I won't shame you for yours. Deal?
The overwhelming majority of us don't have a fetish for recharging stations, and don't want to spend 2 hours a day on our vacations to make short-range EVs seem feasible.
LOL I don't have a kink. It's really not a problem to stop every 3 hours to take a break.
Recharge every three hours?
Masochist.
🤣
It’s not. I own a very nice EV. I can make arguments for and against both EVs and ICE vehicles. If you are comparing battery size (which you did) then you are talking about range. If you are talking about range then you are comparing against ICE vehicles which have ranges from 350 miles to over 600. I used 400 because I own two ICE vehicles with that amount of range and one EV with 265 miles of range. The 265 miles is plenty for everyday stuff, it’s even good for road trips! But you made a comparison of weight. EVs are much heavier if they have equivalent range.
I wasn't talking about range, I was talking about weight.
I certainly don't and wouldn't consider it. But if someone wants 1000 miles of range, we probably aren't getting that without some major technological breakthroughs in material sciences any time soon without packs around 100kWh.
We don't need 1000 miles of range...all we need is more charging stations.
Lack of a need for that won't stop people from getting them if that's an option...
Economics of lugging all that extra battery weight around on daily commutes is why smart people wont go for the extra large pack.
Given what the top selling vehicles are in the US, I don't expect people to be smart, even if they're pay more upfront and long-term for their stupidity.
What people choose to buy does not make "EVs are heavier than ICE vehicles" true.
If you want an equivalent vehicle, you need that kind of capacity. If you want to match the range of a vehicle with a 24gallon tank (ie: if you want to convert a typical ICE truck into an EV), you probably need a 200kwh pack. If you want to match a ~12 gallon tank (ie: if you want to convert a typical ICE sedan into an EV), you probably need a 100kwh pack. If you had a car efficient enough to get 1000 miles on 100kwh, you'd be comparing it to a 3 gallon tank for an ICE equivalent. To match an 8 gallon tank (ie: a 2-seater car), you need about 60 kwh battery. Even if you want to compare a 80mile range fortwo EQ to a 300 mile range ICE fortwo, its already 300lbs heavier without even being close on the range and being quite limiting for even just normal commuting around here (assuming you don't have a guaranteed charger at work).
Don't want to, don't need to.
Really the only thing that matters for the purposes of this comparison is physical dimensions.
What people need and what people irrationally want can be two different things
For the purposes of this conversation, only 1 of those matter. The point is EVs are not inherently heavier than ICE vehicles. They're only heavier if you insist on unnecessarily large vehicles with unnecessarily long range. That's why a Chevy Bolt weighs 3600 lb and a Hummer EV weighs a patently insane 9k lbs.
