“...their new battery cell to reach 85 percent charge, while delivering an energy density of 240.4 watt-hours per kilogram.”
The equivalent for gasoline is 12000 watt hrs/kg
(still some research to go, here)
What are you saying? The Chicoms got us beat in the batteries. We win if batteries are good don’t we. Solar power to feed them is free.
Whatever happened to fuel cells?
You are wrong. That’s comparison is as A FUEL, not motive force.
But a car has to have MORE than fuel- it has to have motor, transmission, etc, which are heavy. Most of the energy in gasoline is lost to heat in the motor/tramission/braking, etc. Batteries are heavy, but so is a motor, transmission, etc.
So, 230-300k hrs/kg battery in an EV is better than a gasoline car - why? Because with a 4500 lb EV vehicle, you can drive 600 miles (more on how this is possible later). Right now, the range of a 4500 lb EV is only about 350 miles With a gasoline car, you need a 16-25 gallon tank to go 400 miles...
I have a Tesla model Y and a Ford Mustang GT. I drive all over Texas in both. My mustang has a 385 mile range, while my tesla has a range of 357 (i have the long range premium model Y). 2 weeks ago I drove from Dallas Texas, to Woodville Texas, in my Model Y. Just today I got back from the same drive in my Mustang GT.
Much cheaper in the Tesla. It now costs me ~60$ per tank on the Mustang. I charge at home at night so unless i supercharge for long travel, my max fuel cost per month is 15$ - that’s right 15$ to charge every night, unlimited.
I supercharged about 2/3 the way to Woodville (it cost me about 7.50$), and supercharged on the way back (that as about 8$) - grand toal 15.50$. it’s a 466 mile round trip - so the Mustang it cost me about 76$ in fuel (@ 4$ a gallon)
What’s funny is Tesla Model Y is on around 170-180 watt hr/kg and i get ~ 350 mile range.
Now DOUBLE that - because with the new generation batteries that are already in production the are getting 250-310 whr/kg. - which would give a range of 550-620 miles. And they charge FASTER, to boot, at the same vehicle weight.
You guys who don’t own and drive both types of vehicles should at least ask somebody who has practical experience.
With this latest battery improvements (By the way, they use sodium, instead of lithium), the game is over. You might want to hang onto your muscle car though, as it will be even more of a collectable. At least until they are antiques.
so, you don’t need 12000 wh/kg, do you?
