TSLA in my hands

I saw the title and thought "Man! That was a quick delivery!"

 

I was thinking that this was a placeholder and a confirmation that Bob will be sticking around for a while.

One thing about Bob.
We'll know exactly how much he paid, how fast it charges, range, repairs, etc.....

Looking forward to it.

 

finally, the truth will out.

 

Wow that was quick! Looking forward to your findings Bob!

 

It was in his hands until his friend took it back

 

But did you drive it?

 

Bob, is your EVSE's breaker at 50A, and you're charging at 40A? Did you set the charge rate limit on the car's screen, or did it automagically set itself at 40A charging rate?

Still using the eMotorWerks 40?

And I also misread your thread title as meaning you now have your 3 already.

 

Those dogs. Hope it likes the new ride.

I've got the same EVSE as you, but it is on a 40A circuit, with our house total at 100A. Great for the Prime, but I doubt highly we could install a 50A breaker for it, legally. But I think one can limit the car (3) to whatever one wants to limit charging to, at the upper end, i.e., 32A or something close. Would just take longer.

 

They should be comfortable with the new Dog Mode on the model 3.

 

If you have a 40 amp EVSE that is not locked down to a lower draw, it should not be on a 40 amp circuit.

An electrical circuit rating is for the peak amperage it can draw. The max continuous draw for anything plugged into it should be 20% lower. That is why vacuums with 15 amp circuit plugs aren't available at higher than 12 amps.

The Prime's charger has a max draw of 16 amps, which is why you haven't had issues. Plug in a car that can draw the full 40 amps from the EVSE, and the base case is the circuit breaker regularly tripping.

 

I am getting out over my skis here. But my understanding is that you can only reach that 40a rate with the Tesla proprietary HPWC (High Power Wall Connector) which results in a 37 mph charge rate. A NEMA 14-50 (which is what I have) is less expensive and limited to 32a and a 30 mph charge rate. I'm sure I will be corrected if I am wrong.

 

Yes, no problem with Prime. 240v @ 16 amps is the most it can take anyway. Doesn't stress the EVSE or circuit in any way.

Re: Model 3... I've learned that the current Model 3 has a charging limit of 32A (@240v) on the lowest of the three range battery packs. A 40 Amp 240v circuit should do just fine and is all that is required. The LR (325 miles) version's charger is 40A, which means a 50A breaker and wiring is suggested, at minimum. However, the charging can easily be software limited in the car to less than that - 32A for example, which essentially can ramp it down to the lower three battery pack top charging limits. Easily set on the screen.

 

TSLA??? Oh, I see, using market symbol. (TSLA.O)

 

I'm pretty sure the 20% I mentioned between the circuit rating and max load is in the electrical code. In other words, your EVSE may not be legally wired up. It may be possible to set the max load an appliance can draw to lower than what the equipment can handle, but these won't be settings an user can easily change.

 

@jerrymildred our resident electrician needs to chime in here.

 

Did your wife get a look at the Model 3? What were her impressions?
