Battery based electric vehicles of today and tomorrow.

Next election will quite likely bring the EPA out of the clouds and back to reality...

God forbid...

Europe: Plug-Ins Accounted For 26% Of New Car Sales In November 2021

Auto executives say more than half of U.S. car sales will be EVs by 2030, KPMG survey shows

If the supply of batteries could keep up with demand, these numbers would be even higher.

I recently read about Shell Oil and a Chinese company working on a standardized, modular battery system. The idea is that you could basically swap battery modules at a filling station in a couple minutes, so one side of the station sold gas and the other had battery sections. It seemed like pretty ingenious solution that addresses range and the dreaded “what happens when my batteries go bad?” type of questions.

In China, NIO already has 142000 battery swap cars on the road and over 500 battery swap stations.
Seems to be working well as a system so far and the driver can chose a bigger battery when swapping when they have a longer trip planned.

What is the cost post subsidy?

Supply chain issues is something I keep bumping up against.

I found the content of this video helpful personally. It's not a feel good video.

Financialization: The belief that companies can make high profits by not producing anything. Once you remove the productive workers from the system, shortages are inevitable. Look at what 2008 did to skilled construction workers. They had to find some other way to make a living, and picking up those tools again after 4 years riding a chair means you are out of shape and out of practice. Many didn't bother, particularly when they realized getting out of construction meant they had stable employment without layoffs.

Finding skilled workers was a constant moan from contractors last decade. Now there is a housing shortage that is not going away, and low income renters are ending up on the street. Sometimes the supply chain is years long.

I don't, but we'll see...

As far as taxpayer funds, not so sure I agree with your thoughts on that either

Roy you know they are unless you see new EVs setting dealership lots.

Where we are moving to ev's or not is no longer a question that is already predetermined. For financial reasons at this point in time is the big showstopper other than EV back orders are so deep.

Without upgrading the grid in major cities, where is the electrical capacity going to come from. I think that is going to be a hidden tax in the EV push. Cities will need huge inflows of capital investment to upgrade the grid. The BBB bill hid those subsidies in the form of charging stations, but the real money was going to companies that could upgrade infrastructure. The thing that will kill EV fast and hard is when people have to make a choice on what to spend their limited electric resources on; home use or transportation use.

That is not a concern in the USA outside of CALIFORNIA. In KY it is 3 cents a mile in my case. It seems like some people are under the misunderstanding that ev's use a lot of electricity.

I don't see the grid as much of a problem, but generation capacity will be quite a bottleneck. The only grid upgrades I see as necessary are connection points to incorporate distributed generating capacity. Urban growth power systems are paid for by the urban growers. Rural people are already used to having to pony up $60k for electricity to their new house.

Hydro is maxed. Nuclear is a bugaboo. Fossil is what we want to avoid. That leaves geothermal, wind, and solar. Geothermal is the only option for gigawatt point installations, though gigawatt capacity is possible with wind and solar.

The average household uses 40kWh a day.
The average EV uses 30kWh per hundred miles.
The average distance each person drives 40 miles a day.

So if the average household will roughly use one and a half times more electricity than now that the grid will be expected to supply. I don't think there is a misunderstanding.
