EV owners of today and tomorrow

[sd455dan]

I wanna "like" your post, but most of what you have shown in my quotes are things I never typed!

Just getting the word out that the US version of the 2024 Model 3 P is exceptionally quick and Pulls hard on the top end which the previous versions do not. My guess is the 2025 Model Y will get upgraded in the top end acceleration as well.



Heh Heh those were my responses to your posts sometimes answering multiple posts I get it screwed up to where I can't break my response out and place it under the quote. Not sure what I am doing wrong to cause that.

Saw a commercial yesterday for the Hummer EV. You can lease one for $850 a month! LMAO!

Plus the required full coverage insurance.

What a bargain

The chart I saw, showed that power level roughly between the motor speeds of 3,500 to 5,000 rpm’s. It falls off pretty sharply below that, which makes sense because you don’t have the rpm’s with the single speed transmission, and more gradually above those speeds.

Who, other than Tesla engineers really know how much of the dramatic drop in motor torque above 4,000 rpm’s is due to air gap concerns due to centripetal force of the rotor, or simply the normal torque drop of the electric motor without severe over driving them.

If they’re purposely limiting torque and resulting HP above 4,000 rpm’s or 50 mph as you stated, and if it is due to concerns of thermal expansion closing the air gap(1.5 mm?) then you would think they would allow roll ons, like 40-70 mph to be driven at full power to the motors since you wouldn’t have the heat build up in the rotor, and resulting thermal expansion from a standard start 1/4 mile.

My guess is it’s a combination of all 3 factors

I watched a few in-depth videos on the subject, and if I'm understanding/remembering correctly, they wrapped the motor's rotor, under tension, with carbon fiber strands. There was something like 3,500psi of tension on that rotor. Much like the carbon fiber wrapped (4,500psi) air tanks they use for air guns and air soft etc.

The idea being that the CF would stop the rotor from expanding at high RPM. Not sure if it was centrifugal force or heat that was the primary driver in the need to contain the expansion. Apparently, the tiny gap between the stator and rotor is key to motor efficiency, so they can't just solve the problem buy starting out with a bigger gap.

My wife drives about 200 miles per day when showing homes...

So 60 miles of charge per night, wouldnt cut it on those days. She would need level 2. Simple math

No, but your tractor sleeps dry and warm while her car sits out in the weather and she has to brave the weather to get in/out. She gets a good paycheck when she sells a home. EV or ICE, you are a bad husband!

A 240V 50A circuit isn't difficult or expensive. I'd move the one I installed years ago to the outside of the garage wall for access on the carport, but I'm building a new house and don't think it worth my effort. 120V gets the job done and when it is iffy I can park under the dripping maple tree to reach the 240V.

New garage will have a Wall Connector just inside each garage door so I can park my 1 EV in either bay, or have a visitor charge, indoors.

The (handshake agreement) buyer of my Porsche 928S spent 5 days cleaning out my garage, going over the car from head to tail, rolling it out and washing, then rolling it back into the garage. Couple months ago. Pending sale of his other Porsche, which the people begging him to sell got cold feet once he was ready to sell. Not too worried about waiting, he did a fantastic job cleaning the car and garage. If the deal falls through, I still have that.

Once the 928S is gone the Tesla Wall (it's not a charger) Connector is sitting pretty at the left rear corner of where the Y will fit. Tesla charge ports are on the left rear.

I'm a bad husband? How so? Quite a declaration from someone who doesn't know me, and who claims I can't have an opinion without literally owning a certain product. . You are too funny. My wife's car is parked indoors. It's the one car that always has been. My point was, not all people have level 2 charging available if they don't have a garage or use street parking at home. In those cases 110v cords to the street would not work because the charge rate is deplorable.
Every single piece of equipment I have is under roof... That's how great a husband and equipment owner I am

250-300 feet of walmart 16/3 extension cords should work well for that 120V overnight charge

Even better when you wake up and it snowed and it’s all somewhere under snow and ice
Fun fun

Sometimes it's simpler just to just insert your reply in capital letters especially if your using cell phone to reply......but Grumpy has difficulty reading that way, ( or any way for that matter ) so you will probably get negativity from him.

This is from the UK and it looks like Tesla is going to be the only 100% EV company come 2030 even after many years of claims from other OEM types.
