In a new white paper, the group notes that boosting efficiency allows for smaller battery sizes, which in turn cuts costs. Most EVs average 2.5 miles per kwh, according to the paper, but the Tesla Model Y averages 3.5 miles per kwh. That’s a 40% increase which, assuming similar range, allows for a 40% reduction in battery size that’s worth up to $4,800 in cost savings, the ACEEE reasons.
It’s absurd to me that the new norm in EVs is to pack 90-100 kWh in a car. With this amount of capacity, I could run my house for almost two weeks (8kwh/day).
Lets build and maintain a proper charging nework so we don’t have to buy batteries that last 600km/400 miles.
With good charging options, 50kwh should be enough for most people.
Shit just make an actually efficent car and you don’t need that massive of a battery to get those ranges. Instead manufacters keep pushing this hideous EV SUVs. The model 3 gets 40 more miles of range out of essentially the same car, just are more aerodynamic shape.
I still don’t understand why not a single car company besides Tesla in its early days is like, shit, let’s look at what consumers actually value and build it. Easy cash grab that puts us ahead of the curve. But no.
That’s the beauty of capitalism.
We could build what consumers actually want. Or we could force them into something they don’t want but makes us more money.
The poor design and manufacturing of EVs by most American car makers is absurd. The EV hummer is just disgusting.
Using my Model Y effective range for comparison, this would drop the range in ideal conditions to about 200mi. In cold weather this would probably look more like 150mi or less. With the recommended 80% limit for regular charging, that could be as low as 120mi. That’s also assuming it’s always plugged in at home which isn’t the case for everyone, and harder to do when you have two EVs sharing a home charger.
The other significant tradeoff is the time it will take to charge on a longer trip. You’ll be charging more frequently, a smaller battery may charge slower, and you’ll need to charge to a higher percentage in order to continue your trip. It may take 20 min to get that first 80% charge at an L3 station but if you need the last 15-20% it could take an additional 25 min. This is also ignoring the increased utilization of busy charging locations, where two vehicles at a single stall will each charge slower.
I’m a huge advocate for EVs but I would not be comfortable with that range or happy with the experience on longer trips, and these are top concerns for potential buyers.
I bought a Model 3 in 2019 with a 50 kWh battery and can confirm that 50 kWh is more than enough for the average person given that efficiency is up to par.
It is now 5 years later and the 50 kWh Model 3 is still the most efficient EV.
Since then everyone just slapped bigger and bigger batteries onto their cars to get larger range numbers, driving up price and reducing efficiency.
I’m excited that we finally see an EV that values efficiency again with the Aptera.
The Aptera looks very interesing and futuristic. I’m not sure that this car will find enough buyers though…
Hopefully they sell enough to make it to Europe, would love to drive one.
It looks so cool, would really love to try it. But if I’d buy an EV, it would probably be something like the Citroen E-C3, starting at 25.000€.
That’s a pretty good price for 44 kWh. Efficiency is not the best and it shows that they used the same base as for their combustion engine cars. Looks like a solid car if the range is enough for somebody.
Not sure where you live, but 8kWh/day is very low for a house. You’d have to have gas heat/hot water and no/minimal AC to get anywhere close to that. Just putting this out there for perspective - almost nobody will get 2 weeks of power out of 90-100 kWh, and if they do it’s usually because they’re burning other fuels. I’m in Colorado in an all electric home and use 3x as much as you. Totally agree that we dont need such bloated EVs though.
You’re right, this is both without heating and cooling. We have district heating, the only thing that is running in my house is a pump. And no AC.
