2. Recharging, under the best of circumstances, takes several hours. More common is plugging into a home charging station for an overnight process. How long will it be before recharging can be accomplished in the same time as filling a gas tank?
There is quick charging. I think most can quickcharge to half capacity in under an hour nowadays. But to get a full charge, I think it does still take a few hours.
Quickcharging will probably improve too.

Do any battery manufacturing research?
My wife works for the 2nd largest battery manufacturer in the world.
AT their last corporate meeting, the were showed an R&D video about a gel they're researching to store electricity. Could be the next big thing. This, of course, is proprietary info so I can't speak too much about it.

For No. 1, you could actually use the batteries in the vehicles as part of the grid. Which is kind of cool, regardless of what you think about the environmental benefits or lack of.
Could you explain this a bit. How can car batteries be used as part of the grid? Maybe you’re confusing car batteries with solar panels, which generate electricity, and batteries for home electrical systems, which store some of that power for later use when the sun is down.
Is the idea here that a home owner’s car batteries can be used in the evening, after dark, to power a house?

I hope it doesn't involve lithium, or anything else that is pyrophoric. Please show her my above WAG about electric vehicle fires. It may be completely wrong, but I do believe it is something battery manufacturers need to sort out.

That settles it. Looks like the OP has really researched things.

I'm down once that happens.

Because it makes them feel like they've done something and in their minds if they feel like they've accomplished something then it becomes their reality.
When they finally get to that point of realizing the shift they'll then focus more on power plants to demand more wind, solar and hydro plants in exchange for coal/gas. Eventually they'll go after nuclear as well.
What will be interesting is to see where the debate goes when solar panels get cheap enough and can perform well enough (and for long enough) that a majority of people no longer rely on companies for their electricity.
On the topic of the cars themselves: I've been saying for a while now that if an electric car comes out with at least 200hp, can travel at least 200 miles on a single charge and is below $30k (and looks half-assed decent), it will change the entire automotive game.

What kind of hydro plants? If you think the greenies are going to dam up more rivers for the purpose of power generation or anything for that matter, you are mistaken.

So lithium batteries are that heavy? I know Lithium is #3 behind Helium but that is a lot of weight.
Ok 1100 pounds on the high side. That's ok.

Electric/hybrid vehicles have always been a scam sold as "green" alternatives to gas/diesel vehicles. You are correct that it's basically a shift, but batteries are arguably worse for the environment in the long term because the materials to make them are much more toxic than petro fuels. Also, we don't really have a way to dispose of them or recycle them.
The other thing is that the power grid works as a sine wave for the load throughout the day (max consumption at peak hours in the middle of the day), so the power companies have been trying to make the load more linear for years. Cars with batteries that will most likely be charged at night is one of their solutions to drive the load up during the typically low points. If they can get the load to be close to the traditionally max load through most of the day, they can produce more power/make more money. As with most things, it comes down to making more money regardless of the consequences.

Yeah, tesla high capacity batteries are like 700kg

I was spitballing on that one. I can see greenies fighting each other on it as it's super green but it has a large impact on local plants/animals.

No, during peak hours to help with demand. Not all cars are charging even though they are plugged in, so they can be used to draw energy from during peaking times while you are working at your desk or in school, or watching reality TV on your couch. I would assume you'd have to authorize it so you don't come out to your car and its only 75% charged and you need 100. Just thought it was a neat concept.

I'm pretty sure now some of you posters are pretty sharp and entrepreneurial. Go for it!

Absolutely correct on all points. I included batteries in the electric vehicle problems, but maybe didn't give it enough emphasis.
