Electric Cars? Food for thought...
Other than all the other obvious reasons why most people can't afford an electric car the big thing I get out of the article is this:
" A home charging system for a Tesla requires a 75-amp service. The average house is equipped with 100-amp service. On most suburban streets the electrical infrastructure would be unable to carry more than three houses with a single Tesla. For half the homes on your block to have electric vehicles, the system would be wildly overloaded."
So an huge upgrade to electrical distribution and capacity is required before mass marketing these vehicles, Hybrids seem to be a better idea.

And then there's this:
Institute for Basic Science
Scientists in South Korea have proven that a new technology will cut the time it takes to charge electric cars to just nine seconds, allowing EV owners to ‘fill up’ faster than their gasoline counterparts.
And even those plugging-in at home will have the time slashed from 10 hours to three minutes.
The new device uses the laws of quantum physics to power all of a battery’s cells at once—instead of one at a time—so recharging takes no longer than filling up at the pump.
Electric cars were rarely seen on the roads 10 years ago, but millions are now being sold every year and it has become one of the fastest growing industries, but even the fastest superchargers need around 20 to 40 minutes to power their car.
Scientists at the Institute for Basic Science (IBS) in South Korea have come up with a solution. Co-author Dr. Dario Rosa said the consequences could be far-reaching.
“Quantum charging could go well beyond electric cars and consumer electronics. For example, it may find key uses in future fusion power plants, which require large amounts of energy to be charged and discharged in an instant.”
The concept of a “quantum battery” was first proposed in a seminal paper published by Alicki and Fannes in 2012. It was theorized that quantum resources, such as entanglement, can be used to vastly speed up battery charging.
+The researchers used quantum mechanics to model their super fast charging station with calculations of the charging speed showing that a typical electric vehicle with a battery containing around 200 cells would recharge 200 times faster.
Current collective charging is not possible in classical batteries, where the cells are charged in parallel, independently of one another.
“This is particularly exciting as modern large-capacity batteries can contain numerous cells.”
The group went further to provide an explicit way of designing such batteries.
This means charging times could be cut from 10 hours to three minutes at home and from around 30 minutes to just a few seconds at stations.
Co-author Dr Dominik Šafránek said, “Of course, quantum technologies are still in their infancy and there is a long way to go before these methods can be implemented in practice.”
“Research findings such as these, however, create a promising direction and can incentivize the funding agencies and businesses to further invest in these technologies.
“If employed, it is believed that quantum batteries would completely revolutionize the way we use energy and take us a step closer to our sustainable future.”

Let's
Heck many places in the US (California for one) are experiencing brown & blackouts for lack of electricity. And this year the water for hydro is extremely low
Yeah if you want to spend $65K plus another $15K for a home charging system to have a compact car that gives you 230 miles of range (when new) and maybe 8 years of driving then you can be an early adopter and get a free Social Justice Warrior Environmental pin to show all your friends at Bingo night.
It's fireproof and waterproof in case you have to sink.
Come on, You're Tryin' to Put Me On:
Let's admit the truth. The electrical system in the DR for sure, but certainly many other places, can not support electric cars en masse.

I am glad this is in the Clown Bin...........because whoever wrote the piece is clueless.
Tesla's or any EV for that matter does not require 75A service to charge at home.
75A does allow rapid charging and that system is usually installed by the vehicle owner at his/her own expense.......not the utility company. Ditto for the charging stations dotting the DR.
I am familiar with 20 Nissan Leafs currently being operated everyday up and down the east coast of the DR. They are charged as needed in the same location and CEPM has not been "wildly overloaded."

A Tesla at home rapid charger requires 80 AMPs at 240 volts, not 75.
The other slow & cheap one requires 20 AMPs and takes 4 days to fully charge a Tesla
Battery warranties expire at 8 years for a reason,
If you can show me how I can save that $20,000 in 8 years on FUEL alone ,
then I will buy one .
The LOGIC most people cant grasp is that the Battery is EXACTLY like a Gas Tank on a REGULAR CAR ..
The FUEL is extra ... but even if it is FREE,
Would you buy any car where the Gas Tank costs $20,000 to replace in 8 - 10 years ?
think on that a moment No amount of Fancy Fuzzy math can dance around those Facts .

20 is nothing, what happens when there are 500,000...etc.
I respectfully also strongly DISAGREE with Playacaribe on this one .
Ask anyone who works for a Utility company, or an Electrtical Engineer .
The Math just does not work .. the Grids can hardly handle AC units in the Hot Months and most Civilized Countries do Controlled Brown Outs or whatever they call them , to keep the Grid up and running ,
Add 500,000 Electric Cars = Disaster .. Hospitals will be FORCED to have Generators that can run 24/7
and those will be using DIESEL .
Probably nothing.
There are currently almost 500,000 in the country of Norway alone;

The stock of electric and plug-in hybrid cars in Norway came close to 817,500 units in 2022, representing a significant increase from 2012 when fewer than 10,000 electric cars were registered in the country.

The complete guide to Tesla charging at home, on the go and autonomously
Each level of charging delivers different charging speeds. Different Tesla configurations have a maximum charge power they can accept. Choosing the right Tesla charger minimizes hassle and installation costs. And maximizes your enjoyment of electric driving. Keep reading to make charging levels...

Well OK, but since the Tesla Level 2 charger can deliver up to 17.2 KW of power at the car battery, you would be under rated, since the amount of AMPs required for 17.2 @ 240 volts is 71.67 AMPs and depending on how far the run is from the power panel there will be some additional losses in the cable. So planning on 80 AMPs would be prudent to prevent breaker trips. And once a modern breaker begins to trip it gets weaker. An 80 AMP dual pole breaker costs from $40-$150 depending on the make of your main panel
At 50 AMPs a 240 circuit is rated to only deliver 12 KW
