You know Tesla has supercharging stations that are free, right? And I think most people who buy an EV are willing to add another dryer outlet to their home. But people who have a short commute don't really even need that.

No one needs a "level 3" station at their home. Thats just unreasonable, unless ypu are rich and don't care about the money.

Seriously.
You have no idea how electrical systems work
you can’t just add outlets to your house if your service won’t support the add. You would have to apply for a second service to the house which isn’t an easy permit to get

Electricity has to be produced as needed. It isn’t stored up. If the transmission lines in your are are near capacity like a lot of Tennessee you’re not getting that permit.

I live on the ridge in Chattanooga. There is playing of land but less than 400 new construction permits available for the ridge. Ain’t nobody getting a stage 3 permit up here.

You are not changing in under 10 hours without a stage 3.

is a Level 1 Charging Station?
A Level 1 charging station is the simplest of the three types. The charging cable that comes with the purchase or lease of an EV is essentially a Level 1 charger. These chargers use basic house electrical current—110-120-volt AC—and many simply plug into a standard grounded wall socket using a common three-prong plug.

The simplicity and low cost of Level 1 chargers are appealing, but their downside is slow—sometimes agonizingly slow—battery recharge times. A good rule of thumb for recharging an EV using a Level 1 charger is four to six miles of battery range for every hour of charging. If your EV has 200 miles of range on a full battery, it can take 35 to 50 hours to recharge the car fully.

We recommend using Level 1 charging solutions only with plug-in hybrid electric vehicles (PHEV). With a typical PHEV, you can easily recharge the battery overnight.

What is a Level 2 Charging Station?
Next up on the EV charging station scale is the Level 2 charger. Level 2 units use 240-volt circuits—the kind typically used for electric clothes dryers.

Some Level 2 charging stations are portable and use the special multi-pronged plug and associated outlet used for clothes dryers. Many homes have such a circuit and outlet in their laundry rooms. But, of course, it is inconvenient to unplug your dryer so you can plug in the charger for your electric car.

For that reason, the vast majority of people who install a Level 2 charging station in their home hire an electrician to run a 240-volt circuit to their garage. Once the power is accessible in the garage, consumers can have the charging station "hard-wired" into that circuit. Or they can plug a portable Level 2 charger into that special 240-volt socket in their garage while also enjoying the ability to take the charger on the road with them.

Indeed, hiring an electrician and changing the home's electrical system can be a costly hassle. But the big advantage is much faster recharging rates that speed recharge times. A Level 2 charging station will often recharge an EV battery in a quarter of the time it would take with a Level 1 charging unit, making it the best charging station for people who buy a purely electric car.

You can recharge the battery for an EV with 200 miles of range in about 10 hours or less. Use a Level 2 charging station with a PHEV, and you can recharge in under four hours.

What is a Level 3 Charging Station?
The third type of electric car charging station is a Level 3, and it is designed for commercial use or for those looking to make a quick stop before getting back on the road.

Level 3 charging stations enable DC fast charging (DCFC), which provides much quicker charging times. Some Level 3 charging stations can bring an EV battery up from discharged to a full charge in an hour or less. Some of the newest EV models offer 400-volt and 800-volt charging architecture, which may allow a high-power battery to replenish from 10 percent to 80 percent in under 20 minutes. That may be lightning-quick, but one can expect Level 3 charging times to get even shorter. The eventual goal is to rival the time needed to fuel a vehicle at a conventional gas station.

Complete installation of a Level 3 charging station could easily cost $50,000. But even if you have that kind of money to spend, it is unlikely that your electricity-supplying utility would authorize a Level 3 charger installation in your home because the electrical grid in many residential areas won't support it.

I'd bet that Level 3 charging generates a lot of battery heat, and that generally shortens battery life. Any time you pump a lot of power into or through an electric device, heat becomes an issue and a lifespan killer.

Streaming was pretty much free or low cost until they hooked enough people. Free charging stations are like drugs; once you have people hooked, then they pay the real price for owning/driving electric cars. How long do you think Tesla and others can get away with providing free power ... think of your own electric bill before answering.

Short of going on a road trip, it’s pretty unlikely that a normal commuter is going to require a full charge in one sitting very often. It’s actually bad for the battery to charge to 100% too often. You can program most EV’s to maintain within a set a threshold.

The charge time and infrastructure are real drawbacks to fully replacing internal combustion. I’d be fine owning one for daily commuting and trips within 100 miles, but if you ever want to go on a road trip anywhere past Atlanta, you’ve got to plan around an EV in a way that you don’t have to for an ICE. No thanks.

The pollution and effect of strip mining to build the batteries are legitimate issues, but that will probably happen regardless.

Funny, there are a half a dozen charging stations in my town that used to be full. You would go to work, and plug in your vehicles while at work. These days there are no vehicles parked in the spots. lol.

Today, the wife and I went to a popular biker bar to get really good burgers. This place is the local biker hang out, these are motor heads. A guy pulled up and parked in an all electric mustang. Everyone just stopped and stared. You heard hushed whispers while he parked.

The world is changing on me again.

Auto mechanic career definitely about to sense the winds of change.

Maybe EV supporters could take a moment and realize they are advocating for something worse then gasoline.

You are asking for a lot there. It's right in front of their eyes - rolling blackouts and power producers asking for consumers to conserve, and EV advocates don't see the problem because they are clueless. Half the people in the country have no understanding of technology, but because they can manage cellphones, they believe themselves technological gurus.

still brakes, suspension, transmission, hvac, and all other components

I'd say that the move to electronics and fuel injection had almost as big an impact as the move to electric motors will have on the fate of the auto mechanic.

In many ways you'd expect EVs to be simpler than our current cars. There's a lot of stuff that's changed in the past few decades because emissions limits have drastically changed how gas and air are mixed and fed to the engine, and the exhaust monitoring changes engines into a semi closed loop system. The added technology that manufacturers won't share has to have hurt independent shops badly.

I don't really have a problem with the evolution of combustion to electric, but what I have a problem with is everyone putting the cart in front of the horse

Indiana, for example, derives 85% of their power from coal. If tomorrow we give all 2 million drivers in Indiana a plug in car what would that help?

The grid upgrade to Nuclear and other alternatives needs to come first, then we can all go home and plug up

I believe Australia, Canada and USA combine for about 50% of uranium deposits...what are we waiting for
