Perhaps one step further would be a standard sized battery pack that a robot could change out - thus eliminating charge wait times and all range anxiety.

Sodium batteries can fast charge, are cheap and work well in the cold and there have been some recent advances in the area with a couple of manufactures already producing them. They figure in a generation or two they could get thousands of charge recharge cycles out of them without any serious degradation. That means a battery that can outlast the vehicle or even two or more! EV's are a lot cheaper to make than ICE cars, except for the battery, there are far fewer moving parts, less maintenance and less cost to run, so the cars themselves should last longer. Some EVs even have the electric motors in the wheel hubs and other than the wheels and steering there are no moving parts. Brakes are seldom used with regenerative braking so they should last the lifetime of the car too, no cooling system, no exhaust system, no oil, fluids, no transmission, just windshield washer fluid. Cheap batteries mean cheap cars and better batteries are a lot less bother than the current crop of Li-ons that need cooling systems and complex charging systems.

that would be awesome, but that's asking for a level of uniformity from several different auto makers that have never had to or wanted to cooperate to such a degree before...that may be a large problem.

Better batteries and more fast charging stations have pretty well eliminated the replacement option. Getting them to cooperate on charging connectors will be like herding cats FFS

the government can force the issue, especially if Mexicao and Canadia get on board with the same hardware
but as you say, the replacement idea is probably moot, the extra hardware at the charging stations would be a negative, too many moving parts, requiring too many maintenance type people.

now the question is, was this operator error, or muck trying to commit negligent homicide?
i know which answer i'm expecting, but i'll withhold judgement till there is more info.

In a stunning precident the courts will rule that those who died while self driving cars died of stupidity and manufactures were not held liable. Death by stupidity will make new law! :lol:

To get the federal rebate the car would need to have the standard plug ins, that should do it!

you're damn straight, time for some accountability in the world of high finance.

never mind finance. It’s the hard sell of a technology that does not meet spec. When the spec says 330 miles, that needs to be at minus ten into the wind at full vehicle weight with the accessories on.

The “MPGe” of everything out there needs to be made honest across the range of conditions a vehicle is expected to meet. So add two bikes on a roof rack to the above challenge. Draggy little fuckers.

They are already forcing the issue with the connectors for phones and other devices to reduce the amount of e-waste ending up in landfills. I believe it's the USB type connectors used for iPhones is the one selected. I liked the magnetic ones they used for the old MacBooks but they were just for power and more connections are needed for data transfer. When a pet or kid or being too high got the cord tripped over it just popped off with zero damage unlike what we have now.

Now if they could come up with a standard POS machine at stores I'd vote for whoever pulled that off. Such a PITA the way they work now.

I don't see an EV in my future. Too many long distance trips from the middle of nowhere here and -30C will tax the hell out of any battery.

:peace:

I believe the industry agreed on a standard EV connector design (J1772 in North America) with the only exception being Tesla. I would imagine at some point Tesla may allow (or will be forced) non-Tesla EV's to use there chargers using an adapter, but it's not possible right now as the chargers must verify it's a Tesla.

ICE vehicles will be around for a really long time, and I would put a good wager that we will see manufacturers produce EV's that still use gas/diesel. Ram has said the "extended range" version of their EV trucks will use the on-board generator option rather than a bigger battery. It will still be a fully electric vehicle/drivetrain, just using the on-board gas/diesel generator to recharge the battery when running low.

I think state licensure of chargers might be an elegant solution. Treaslas are really big in CA, and Superchargers are everywhere. I imagine the chargers must be up to date on annual registration and safety signoff.

Simple: Tesla can keep nonconforming Superchargers operating, but at a serious surtax compared to compliant charging stations. Situation should sort itself out, fast.

As for Diesel-electric trucks, the tech is quite advanced for, say, locomotives. They get great thermodynamic efficiency (% of fuel energy turned to usable work) because they are tuned to work at one rpm and a steady heavy load. Turns out they are two-strokes! (Big ships, similar deal except mechanical energy goes direct to the screw(s).)

So an electric Ram with a small two-stroke Diesel sized to provide most of the power needed to pull a fifth wheel under highway conditions sounds to me like best of both worlds. I’d be surprised if Freightliner isn’t working on something like that for semi tractors.
