Capacitors aka super caps, can accept & store a huge amount of electricity virtually as fast as the grid can supply it.
The closest thing to becoming a reality would be Al-ion which can charge almost as fast as a super-cap. Super-caps have had their reputation tarnished by failed deliveries. If you look up “grabat” which was the graphene based super-cap developed in Italy, it was marketed as being sent to manufacturing back in 2016, but it never happened. In fact, they are still working on it. Super-caps have technical issues which have not been resolved yet, at least to make auto batteries viable. The problem with super-caps is the layers are thin and rated to small voltages, and the electrolyte can break down and super-cap layers can short. There is a lot of surface area that can fail. You’ll probably see Al-ion before super-caps.
Capacitors are definitely a work in progress, I see them being used to reduce the charging time needed by taking on power quickly then releasing it into the batteries as required, and also to make 'regen' energy capture faster and more complete, again to be released into the batteries as required.
Possibly even a hybrid battery cell that combines both high capacitance for charging and gradual power release for driving.

Apparently a shortage of microprocessor chips is a substantial reason for the current delay in vehicle production. Does anyone here know if bitcoin mining has absorbed much of the chip production?

The answers to every question EV owners get asked by the uninformed.

Despite which semiconductors are being produced, you can only produce them so quick, while testing and binning takes a lot more time. There have been a few disasters that have affected the semiconductor industry such as the fire at renesas, water shortages, and other various problems. Certain production was slowed when the pandemic hit. Now the foundries are playing catch-up. There are endless products with semiconductor parts… even individual FETs are becoming more difficult to get so the problem is not just large or powerful processors, but all parts including transistors, power regulators, capacitors, resistors, etc. the semiconductor parts on a video card is such a tiny cross-section of parts the entire electronics industry uses.

EVs can have up to twice as many semiconductor parts.

Doesn't seem to be slowing Musk down.

New a man in San Diego, who in the mid 1980's started a company that salvaged components from circuit boards, three or fours years later sold the company for 3 million bucks.
It turns out that salvaged chips are just as reliable as new, if they test good after salvage. The chip salvage industry is doing quite well thank you.

Due to the extreme shortage, auto manufacturers are omitting some features, reducing some features and in some instances, swapping digital for analog displays. The chip shortage is worsening. For the average electronics based industries, lead times can be a year or more for many types of microcontrollers. Companies are re-designing to use alternate parts, what-ever can be found. Salvaged parts (which most would not want to use) does not begin to plug the hole nor does it necessarily give you the parts and volume needed. Chip manufacturing is a slow process. Thankfully the US will be adding more capacity, but it can take 5 years to build a chip facility.

Tesla has to some degree, redesigned and re-wrote software for alternate available chips. It also helps to have 6 months of extra stock like what Toyota does.

Here is a funny video of a deep green activist trying to go to a conference in an EV.
Needless to say, she gets all flustered, confused, and late.

Ford developed the Mustang Mach-E. The Mustang Mach-E is a new American icon that should be celebrated. Seeing Ford take one of its best-selling and most prominent vehicles and electrify it is great. However, had they done that before Tesla was founded, then they would have been considered the leader of the EV revolution. Instead, they have been far behind Tesla.

Ford and General Motors are not leaders and will not be until they are selling more EVs than ICE vehicles. They have to beat themselves, not Tesla, to win. For now, it seems they are only here to beat Tesla — and they aren’t even close.

Resent cold snap that hit the area I noticed numerous mustang mach-e’s on back of tow trucks, it spoke volumes. Biggest stay the hell away.

When Al-Ion batteries come available, hopefully there is an upgrade path.
I think I'd rather wait. IF and WHEN Al-Ion comes, then, charging is no longer necessary at home and few stations would be needed in the city. A far better solution in every aspect.

EV ranges have almost doubled in the last 3 years, there is a ton of research going on with battery chemistries, so we can expect range to increase and charging time to decrease over the next few years.
Will have to wait and see, but the writing is on the wall, Electric cars are on the way.

That is the company making the big promises. Starting with coin cells, then branching in to devices and auto batteries. So far it is just a promise with lots of research money. Not as though it is the only company too and that is why I am skeptical. I've seen these sorts of promises many times and previously with the graphene super-cap battery. That promise failed 6 years ago. So we will see. I'll wait for Al-Ion since it will likely be here before solid state lithium and be a lot cheaper. Once they start installing the Megawatt chargers, then the real revolution will start.

Amazing that you saw numerous Mach-es you must have seen both of the two in the Okanagan.

Check out this article about electric school bus in Alaska excerpted below;
Electric vehicles are continually proving to be able to handle the cold unexpectedly better than many tend to think they do. There have been several cold-weather tests in Teslas and other vehicles since the Virginia highway winter disaster earlier this month, and there were many others for years before that. One such experiment took place in Canada, where temperatures recorded were 22 degrees below zero and 31 degrees below zero. Although that’s not as cold as 48 below or even 80 below, this does show that the myth that EVs don’t work in the cold will be known as such by the mainstream.
