If the circuit breaker installed is 60amps, then the car will pull 48amps from a properly configured HPWC. The code for continuous draw is 80% of max, so 80% of 60amps would be the 48amps you are seeing.electrician cam back by, so its now at 240v, 48amp, and 34mi/hour, is this more normal?
we finally looked the RTFM, which i honestly thought was a switch or something and had to google it... LOL
i have a model s p90d, 2015.
However, there is the idea that low temperatures and high SoC can induce Li plating. Anyone have thoughts on that?The US Army study is on the Roadster chemistry (LiCoO2) and the NREL study is on the Model S chemistry (NCA). Both studies have similar results, and Tesla battery management is similar for both the Roadster and Model S, so the general principles can be applied to both.
The Battery Management System tries to keep the battery above freezing and below 104F. The US Army study has three runs, one at 32F, one at 68F and one at 104F, so it's an excellent match for the BMS range and can be used to bracket what we'd expect to see in the real world.
The overall conclusion is that low temperatures and low SOC help extend battery life, and high temperatures and high SOC reduce battery life. Both in combination are especially bad. A low SOC can help protect against high temperatures and low temperatures can protect against a high SOC.
Even Elon said the batteries should last forever in Alaska. If you're in a warmer State (or have a hot summer) then lowering the SOC will help protect the battery.
Personally I don't think this is too complex for the average person, but will take some education. I think it's mostly about managing expectations for potential buyers.
When I bought my Roadster I expected the battery capacity would drop to 70-80% over 8 years. If I run at 90% Standard Charge in a warm climate that's probably true. Now that I know I can get better numbers by dropping the SOC I'm a very happy camper, especially since I don't need the full Standard range on a daily basis. So far I've seen no degradation after three years by running at 50%.
different peopleYou can still set the charge to 90% (standard was 92%) and leave it. Not too complicated.
People asked for this feature so Tesla provided it. Now people say it is too complex.
Do you think that 40A (9 kW) is better or worse than 30A or 20A (4.6 kW)? I mean with a Wall Mounted, where you have a choice of currents. Would love to hear why there might be a preference for one over another.Notes taken at the recent Tesla Tech Talk in New York say that you should charge at 40A when you can (i.e., better than 110V/12A)
i only had a certain amount of current or something, kinda naive here, to address to the tesla part becuz of a/c and other electrical stuff i guess... if this seems normal, then i def feel better about it. My theory was, i sleep, then when i wake up , its charged; which now seems like is logical at 34mi/hour...Well, for 28amps, you are getting about what you should be getting. The real problem is you should be getting more than 28amps from the HPWC in the first place. I have a feeling it's set low or the electrician screwed up somewhere else.
Here's what the manual says for settings.i only had a certain amount of current or something, kinda naive here, to address to the tesla part becuz of a/c and other electrical stuff i guess... if this seems normal, then i def feel better about it.

You guys are all overthinking this. If you don't need or want the control, set it to 90% or whatever and don't fiddle with it. We're talking about a relatively small difference over the life of the pack.
I agree. I have a 2015 Model S 70D that will be 4 years old this October. My loss maximum travel miles has decreased from 285 to 283. I keep my charge level at 200 miles for daily which is roughly 70%. I still have over 5 years of warranty life left, so I am really not worried about it. i believe I can get 12 to 15 years out of this pack. I will have another Model S by that time or whatever Tesla current model monicker is available.
I find this hard to believe... the Model S 70D range was 240 when brand new. Tesla Model S - Wikipedia

I also believe that the EPA rating is an average based on certain standards, like speed, weather conditions, slowing down for slower traffic and speeding up above the average speed. I believe that standard is 65 mph.
How are you calculating your range... rated or ideal?
You’re not “losing” mileage to power other items, (except a little for A/C and more for heat which wouldn’t apply in Florida). You’re using more energy to propel the car at a speed faster than the EPA test cycle. If you would drive the EPA test cycle you would get the rated range. That’s what rated range means.Generally speaking on my Model S I have observed if I keep the speed at 65 on the interstate, during daylight hours, I only lose about 10 to 15% of total mileage that is used to power other items (a/c, main screen, dash screen, etc ..) So net driving miles at the high level is about 240 miles. I believe Tesla places a Supercharger around every 140 to 160 miles apart.

No it’s not. The EPA test cycle is a complex pattern of multiple speeds for different amounts of time, and none of them are as high as 65 mph.I understand that. I drive 65 which is the rated speed by EPA.

I really don’t care about all the weed dipping. I’m done with this argument trying to say what is right or wrong. I just know what happens with my Model S. I am sure you know what happens with your Tesla. Have a good day.
