Separate names with a comma.
I'm not denying anything. Your constant mischaracterizations are fundamentally dishonest. It makes having a civil discussion very difficult. Are...
Exactly. 50 miles per charge without adding any weight is easily doable from an engineering perspective. I think Toyota is working with...
I'm comparing the total 8.8 kWh of the Prius battery vs. it's 265 lb. weight. And as far as the suitability of 18650 batteries for EV use, that's...
I "claimed" the energy required to move a mass a given distance is independent of the energy source. That is a fundamental fact of physics. It...
This thread is about EV range, so gasoline efficiency isn't germane. It's still an interesting discussion, and I'd be interested to see data...
What would make the thermal efficiency change when driving over a hill versus driving in the same conditions on level ground?
I was just getting ready to add that Toyota's current battery has a specific energy of 73 Wh/kg. Even my Panasonic 18650 cells I use in my...
The Prius Prime's battery weighs in at 265 lb, which is 10.6 lb per mile of EPA range. Bumping the car's EPA range to 30 miles would require...
I'm sorry I missed it. I skimmed this thread and didn't see any posts of that nature from you. Could you please link to the one with the...
Please explain for me using physics and showing your calculations how you can move a Prius over a hill using no more energy than moving it the...
The only silly thing in this conversation is the idea that you can drive a vehicle n miles up and down gentle slopes using the same energy as...
The slope is irrelevant. You cannot recapture 100% of the energy used to climb a hill by rolling down the hill. It's impossible no matter what the...
It cannot be recovered in any sense. There's no way to travel up a grade and then coast down using the same net energy as traveling the same...
You can't recover it all. You'd have a perpetual motion machine if you could. If that were true, when and where you use EV would be largely...
If you have to give it more "gas" to go up the hill and/or use the brake pedal on the way down it will be less efficient than cruising the same...
40 miles round trip uphill/downhill will use far more energy than 40 miles on level ground.
It will always be the same delta, about ~40Wh/mile less for a 0.75% slope.
It's always more complicated than the net elevation difference because going uphill uses far more energy than is recovered or avoided going...
That's a steep enough slope to roll the car in neutral, so it won't take any accelerator to keep moving. That can go on indefinitely as long as...
Just going by potential energy of rolling a Prius down a 1,500-foot slope, it "adds" 1.7 kWh to the trip. So, 25 - 38% left would be about 0 - 10%...
