For most use, charge time is irrelevant, as you simply charge the car at home, at night. If you need to drive more than 320km per day, (200 miles) then charging becomes a problem. I very seldom need to drive more than 320km in a day, so for me, it would be ideal. The most I drive, other than a few times a year, is about 200km in a day, with the average day being no more than 70km per day. At a Tesla Supercharger, you'll get about 170 miles / 270km from a 30 minute charge.
In these parts it's a problem. Around here a 450-500 mile round trip is a day trip.

How often do you drive those sort of distances Jim?

One of my best friends has just come back from 9 weeks in China. He's a professor and was sent there by his institution to teach a class - pretty complicated chemistry that's completely over my head.
One of my best long time Pentax pals is also a professor, and has done several year long tours there over the past decade. He has given me a ton of insight into a rapidly changing China. I think all in all, it has greatly impressed him. They are passing us up lickity-split on education for the masses.....very fine education.....and in areas of renewable energy and making a clean environment. We seem to be going in opposite directions.....

He is also a skilled photographer and processor.....as well as a gifted antagonist....we've been thrown off several Forums together over the years...including this one! Pals to the end...right or wrong!

Here is some of his work and some of his China shots.....some very interesting stuff!

Electric cars......self driving cars.....it is all in the future and the future is very, very, near. The batter charging problem will be solved....there is too much money involved for it not to be.

Regards!

In the US the power grid will simply not handle millions of cars charging overnight.

Been to many of those back in the days of my youth. I hated it when they were not close to the house...and for aromatic reasons, they seldom were. On a cold dark rainy night, we guys could pee off the back porch.....ladies had their "bed pans".....but if you needed to do more, it was a really painful experience. Cold...wet.....not a time to get stomach cramps or diarrhea!

For fresh bread or donuts in South Dakota, a man's gotta do what a man's gotta do.

I very much doubt we'll break the grid any time soon. There's huge surplus capacity at night and the take-up of electric cars is slow.
See, for instance, Will Electric Cars Break The Grid? | CleanTechnica

Here by us, greater than 81% of our electricity is from renewable sources (mainly hydro and wind). In your case, that may not apply.

the rest of the world doesn't get it

i'll put 200-300 miles on just running from site to site taking pictures or fishing
and I do that two or three times a week

several times a year we do 500-1000 mile days while traveling
I remember my longest one day as 1273 miles

it helps that we try to avoid going east of the Missouri or the Mississippi at worst
too many people driving too slowly

The limitation on electric cars is the time it takes to charge the batteries. If some breakthrough could bring that down to around 30 minutes (=enough time to eat lunch) with a reliable distance of about 350 miles (= about as long as anyone should drive without stopping) even when running the heater/wipers/radio, that is when electrical vehicles will really revolutionize personal transport. But, it may not be a problem that will have a solution. Because we can imagine it, and want it, and hundreds of top engineers and scientists are working on it does not mean that it is possible.


I have thought about the problem of the recharge time for electric cars. A solution would be for the whole industry to agree a single car battery pack standard, or perhaps two. The packs would be designed to drop out quick and be replaced, kind of like F1 wheels. So we would go to the battery change place, just like a petrol station, drop out our batteries and put in a freshly charged set from the rack, and get going. The time would be like for a refill of petrol.


Now you ask, who pays?


Well, when we buy the car we do not buy the batteries. The batteries belong to the electric supplier, and we pay for a change over fee and the metered power we took from the batteries we are dropping off, rather than for the power that charges them. The owner of the batteries will notice over their life that capacity decreases, resulting in it costing them more to charge batteries to get the same sales revenue. That would result in the owner of the batteries recycling the old ones and replacing them based on their business return. In turn that would save the vehicle owner from being confronted with a huge lump sum cost to replace the batteries.


So power would be sold as a service, just like petrol, rather than as a product, requiring big lumps (bunches) of money.


If the industry cannot work out the standard, get a legislator to declare the standard. Self-interest would result in the industry working out a good standard.

But my problem is, I can afford one car (like many people), so the same car I commute in is the one I take when I go on a longer journey. The solution needs to be satisfactory for both uses.


In Australia, when petrol prices went really high a few years back, people seemed to drive cars about as much because their lifestyle demanded the transport and they do not have enough money to have a low fuel use vehicle, like a small motorbike, to use for the trips where it would make reasonable sense, and make it much easier to find somewhere to park.

Education in China.


Our political rhetoric is that education is the right of the citizen. Therefore it s seen as a current cost on government.


Their political rhetoric is that education is the responsibility of the citizen, to submit themselves and to learn in the education system, and the personal rewards for education are high - nicer jobs that pay several times what basic jobs do. And the government views spending on education as the government's investment in a life time of higher income tax revenue from the educated person. Simple business ROI calculation. Also, research at the universities is treated as the front end investment in new ideas to help carry them over the valley of death between the fundamental science published in the journals and the stage where a company can see the technology is mature enough to commercialise.

I have been following, with interest, what Elon Musk is doing with Tesla. He's manufacturing in the USA, of course, and if he delivers what he promises, I predict we'll see a technology change, in our lifetimes, not unlike the change from the horse and cart to the motorcar.
The numbers I have found say that about 25% of new cars sold in Norway so far this year are fully electric, with another 25% being hybrid dinosaur/electric driven. The increase in electric cars has come very quickly indeed, and it doesn't look like the trend is about to turn.

In South Africa, a big day's drive would be 800km / 500 miles. Here, because of our (slow) roads, 650km is about the practical limit for a day's drive. Either way, that will require two charging stops in a Tesla, adding 1 hour to the journey. (not counting petrol stops and bathroom stops in a petrol car) I can live with that as those are distances I do, at most, a few times a year. For the rest of any given year, my daily needs are such that I would not need to stop for a charge. I realise this is not ideal for everybody. In the USA, I have driven as many as 500 miles in a day, so even there this model could work for me.

I would not want to try it on for a 4x4 offroad adventure. For that I'd prefer my scratchy old Landrover!
