Battery based electric vehicles of today and tomorrow.

[Grumpycat]

Only thing I learned is if a Tesla battery fails once warranty is over it will cost FAR more to replace than I ever paid for any of our ICE cars or trucks.

Not going to watch a 15 minute video for 15 seconds of data.

If you pay John Deere rates for a new engine you will pay out the nose. Just as happens if you pay Tesla for a remanufactured battery.

There are many videos on the internet detailing how to replace a Tesla battery. And how to use parts of one to resurrect 2 or more others.

No, i dont think the outside world really understand the US, people look at it as a single country but really every state is its own "country" with different laws and culture, and people know it through TV, and that are of course ivery fare from the truth. And the foundation of the US is so different from states that has evolved out of thousands of years history so little of the society is directly comparable, for me the big focus on religion is strange, here religion is a very privat thing that is not a subject you states in public.

And crime must be a much greater problem for people, it seems much resources are used on safety, guns and other safety related things in the US.

Very astute...

I wouldn't go so far as to say individual states are their own "country", but for many purposes regions could very well be. There was a book written in the late 70s called "Nine Nations Of North America", and while some of it is a bit dated the principle still applies. The "nations" didn't just encompass the U.S. but included Canada, much of central America and the Caribbean. The author defined the "nations", and explored the culture of each one. Cultures between nations can be quite different, it's amazing we as a country get along as well as we do.
Interesting reading if you can find a copy.

Every now and then I come across an online essay, usually written by a European transplant on how this and that is being done "wrong" by Americans. They don't seem to grasp that despite being "western" nations, their culture is as foreign to us as ours is to them.

Interestingly, people in large countries express distance, as compared to smallish countries. I was talking to someone about how a mistake in location, took me 3 hours out of my way, a person from Germany over heard and laughingly said he found it interesting on how Americans talk about distance. Now this might not be a very good generalization, because it's based off of ONE instance, that i had.

I think you’re right. I talk to Europeans who travel 250 miles to another country and think they’re worldly, international jetsetters who are so much more knowledgeable and cultured than those Americans who never leave the US. It makes me wonder if they realize how large and diverse the US is. You can drive from Rome to Prague and pass through 4 different countries. It’s further to drive from Texarkana to El Paso and never even leave the state of Texas. And if you think the culture of Miami and New Orleans and Seattle are the same you’re very mistaken.

The religion thing is mostly an urban vs rural thing and can vary quite a bit depending on where you are. Overall almost 1 out of 3 Americans don’t affiliate with any religion and that number is rising fast, so while you hear a lot about it in the news I’m not sure they’re presenting an accurate picture. Like so many things, you tend to only hear about those who yell the loudest and those are the extremists.

As to crime, that’s a hot political issue and I won’t comment other than to say it’s very localized and the result of a perfect storm of many causes all working together. I have homes in different places and different states and in one I literally never lock my doors and leave my keys in the car. In another we have an alarm and I keep a loaded gun next to my nightstand. Simply talking about ‘crime in the US’ tells you very little.

I seem to recall seeing that a Tesla charger is about $20k.

The Tesla charger level 2 sells for $415. An average expensive installation is about $3K.
Do you have a source for the $20K to see what it includes? Even with major electrical updates to the garage I can't see $20K as an average price. I can see $2K as an average installed price especially for people who already have at least 200A service.

Tesla starts selling home charger that works with other EVs

As it also starts opening up its Supercharger network.

www.theverge.com

Tesla should not even sell the level 1 charger since it takes 4 days to charge the vehicle. (These are the people who probably trade in their EVs for an ICE.

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...

You cited an EVSE not-a-charger Tesla Wall Connector with J1772 plug for $415. That product can no longer be found on tesla.com.

A Tesla Wall Connector sells for $550. It is a J1772 EVSE but with Tesla's North American plug. Many have purchased Tesla WCs then replaced Tesla's plug with a J1772. It appears this is exactly what Tesla did to create this product.

Tesla was forced to use their proprietary plug because the SAE committee would not agree on a common AC/DC connector. Tesla wanted AC and DC on the same pins, other members opposed. Forced to commit to production for the 2012 Model S, Tesla did their own thing resulting in the elegant Tesla connector as opposed to the ugly J1772 and the uglier bastardized hybrid CCS.

As for cost of installation: 6/2 CU wire and a 50A breaker. How hard is that for a TBNer? Yes, 6/2, not 6/3. EVSEs do not use neutral. 6/3 is required for a NEMA 14-50R outlet which requires neutral to split the L's into (2) 120V circuits.

The cited J1772 Wall Connector is Tesla's 2nd generation design. 3rd generation is current. Other forums found it attractive because up to 4 Tesla Wall Connectors can share the same circuit intelligently managing the load so one does not have to rotate multiple cars in/out as they charge. If 4 want to charge at the same time then each automatically gets 1/4th. But if 4 are connected but only 1 wants to charge then it gets everything. However, Tesla said this one would only load share with like WCs, not with other generation 2 WCs connected to Teslas. Had people scratching their heads. And now this unit is no longer listed for sale.

There seems to be no difference in charging speed between a 48 amp and a 80 amp charger.
I know the info is not from a Tesla site, but is it correct?

I found a 3rd generation Tesla charger on Amazon (last one) for $799, Where is it for sale for less? How do you know the maximum Amps required for the different models of charger? Is there a 48 amp and an 80 amp charger, or is charger variable dependent on the line into it?

Old data. Partially correct.

Early Model S had a factory build option to include two chargers in parallel on the same charge connector. Each 40A. Allowed 78 MPH charge rate with an 80A Wall Connector not-Charger. On L2 an EV charges at the lesser of its own capacity or what the EVSE offers. An 80A EVSE does nothing extra for an EV that can only accept 40A.

On the model update known as “face change” and introduction of the Model X the twin charger option was deleted in favor of a single 72A as standard equipment.

The Model 3 Long Range (and maybe others) have a 48A onboard charger. Base model is 32A. Early production did not charge at up to 250 kW at Superchargers but is my understanding all current production Teslas accept 250 kW initially if the battery charge is low. All Teslas slow the Supercharge rate as the battery fills.

Superchargers are chargers because the power regulation occurs outside the vehicle in the Supercharger. Tesla Wall Connectors are not chargers because the regulation occurs inside the vehicle. Wall Connectors are nothing but enhanced extension cords.

Tesla.com lists the Tesla Wall Connector for $550. All WCs for sale originated at Tesla.com. I do not know if they are back ordered. However if one buys a Tesla then a Mobile Connector is included with the vehicle. Am told you now have to order the adapter pigtail to match the outlet, whether NEMA 14-50R or one of the common dryer outlets.
