and if he lets it sit for a day he has to start all over again ?

Approx 37kW-hr for 1 gal gasoline.
Therefore 250kW-hr is similar to 7 gal of gasoline.
However, electric motors are 95% efficient vs gasoline engines, which are 40% efficient.
So you would need ~16gal of gasoline to do the same kind of work.

Last I checked, Hummers had 32gal gas tanks. Gasoline Hummers had twice the energy that EV Hummers have... and can be refueled much faster.

If someone invents a lightweight gasoline fuel-cell (gasoline-to-electricity), you can make a gasoline-powered EV which gets the twice the range of gasoline because the electric motor is 95% efficient.

Potential EV buyers cannot possibly understand the advanced math/calculation. Their heads are filled with virtue signaling and good intentions, the right brain is so big that the left brain doesn’t have a chance.

Wow! You sucked in a trove of light readers on this one, John! This may be the most comments I’ve seen on your satire gumbo!

How quickly will this diminish the lifespan of the battery?

Turning one charge cycle into two seems like it would do just that.

Not sure on tesla batteries, but I know older Prius batteries were good for about 200k or 10 years.

“Not sure on tesla batteries, but I know older Prius batteries were good for about 200k or 10 years.”

Prius is a hybrid, not an EV.

Tesla has been testing a battery that shows so little capacity loss that they are saying it could be a 100 year, one million mile battery.

Tesla real world data shows that their batteries installed years ago are good for 20+ years and several hundred thousand miles.

I am aware of the difference between the Prius and the Tesla.
I only mentioned the Prius battery as That was a Battery data point I am familiar with. It is significantly smaller and used less. to me, a larger Tesla battery would have less of a lifespan.

Thanks to your info, I see I was wrong.
My only question is how exactly is Tesla testing that battery.

Lab tests will always outperform “real Life” statistics. Still, I figure the battery would need to last for 200-300k to well outlive the average lifespan of most Vehicles. so the lab test, even if its grossly over estimated, will still surpass the 300k mark.

This means that using teslas as Grid batteries would be feasible and not negatively impact the Performance of the battery, which is good. Decentralizing the grid is a good thing, even if its just a small thing like this.

“My only question is how exactly is Tesla testing that battery.”

They perform discharge charge cycles. There are different technologies but basically batteries are made “larger” by just adding more cells.

It’s satire, dolt.
