First file: A friend with a long range, Model 3 visited one of my two, L2 chargers, for a quick test: 40A - definitely expected, the maximum rate for that EVSE test at 1 minute - the Tesla Model 3 did a brief current drop which is how to test if the EVSE and circuit breakers are at a marginal rate. Resuming at 40A means this is a full power circuit and the Model 3 can easily handle a full 40A. Very clever, Elon's team. Bob Wilson
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.
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.
It is a 50A circuit and the EVSE is rate limited to 40A. Right now I have the reservation and costs. So I’m working on getting everything ready. The Prius Prime will be cleaned out and taken for detailing to clean out the dog hair. Bob Wilson
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.
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.
A more recent tweet suggests the real time intervals are "2-4 months", not "2-4 weeks." <GRINS> Source: Tesla produces first batch of standard Model 3 vehicles - Electrek Less than a week after having launched the new base versions of the Model 3, Tesla has already produced the first batch of Model 3 vehicles with the standard battery. The long-awaited standard version of the Model 3 is not only available to order, but it’s now also rolling off the assembly line. Electrek was able to confirm with a source familiar with Tesla’s production that the automaker produced an initial batch of over 500 standard Model 3 vehicles over the last two days. Today, Tesla has 550 standard Model 3 vehicles ready to ship. . . . Elon just said that Tesla shouldn’t reach volume Model 3 standard battery pack production until ‘mid-year’. Source: Tesla shouldn't reach volume Model 3 standard battery pack production until 'mid-year', says Musk - Electrek That makes more sense. I assume production of the new version is going to be fairly low in the coming months. After all, they have been presenting the base Model 3 has been dependent on Tesla slashing its retail costs and as we reported last weekend, Musk admitted that they are just starting a review of the operations that will last for a few weeks. Actual meaningful savings probably won’t happen for a few months – when Tesla is going to start producing the $35,000 Model 3 in volume. With the increasing numbers of options now available for Model 3, I am starting to be curious about the mix of sales – especially when it comes to the battery packs. Before launching the Model 3, Musk estimated the average sale price at around $42,000 once all options would be available. Bob Wilson
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.
Week 01 :: ordinary e-mails and phone calls to resolve questions. Encouraged by: Tesla Model 3 Standard Production Already Exceeds 550 Tesla Model 3 Standard (the base battery pack option) is not only available for order but reportedly, the first batch of more than 500 were already produced. According to Electrek’s sources, some 550 Model 3 Standard are ready to ship. It’s more than one would anticipate in the initial stage, which suggests that Tesla is already ready for volume production of the Standard version. . . . Bob Wilson
