    Is it safe to use 70 amp breakers for home wall connectors to charge Model 3?

    MY SR+ can only draw 32 amps from my WC, and therefore only requires a 40 amp breaker, but I installed it with a 60 amp breaker and thats perfectly fine. I could also have used a 70 amp or even a 100 amp breaker as long as the wiring would support it. People get confused as they think the CB is...

    Is it safe to use 70 amp breakers for home wall connectors to charge Model 3?

    No, that’s incorrect. Think of it this way, a regular wall circuit is either 15 or 20 amp, and you can install a door bell on one or an alarm system, sprinkler systems and or dozens of other things that don’t even come close to the circuits rating. There is NO safety issue with an item that's...

    Charging Costs

    Teslafi once you tell it your utility rate will compute each charge to the penny. If you look at my electric bill it says my rate is 11c per KWH, however if you divide total bill by KWH used, you get .14C per KWH. Seems AVERAGE US residential rate is 13.31c Per KWH Electricity Rates in the...

    Wall Connector Decision

    A few points, First these things we keep calling a chargers, are not chargers, the AC charger is in the car, Whether WC, or destination “charger” or travel “charger” or whatever, they aren’t much more than sophisticated plugs really, they provide a safe connection from the Grid to the cars on...

    Longer term Ohmmu experiences?

    unless I’m mistaken, the dark current of those mods is really minimal If you can get the OEM battery as cheap as we can in the US, you cant make a fiscal argument against one, but if OEM is expensive, there are other very good deep cycle group 51R batteries, notably Optima and Odyssey. US...

    12V Battery Just Died - Total battery failure

    14.3 and 13.3 are ideal voltages for good quality AGM batteries, 13.3 is float voltage of course. I’ve never heard of an auto dropping to float, but it’s the ideal way to treat a battery, most autos just run 13.8 to 14.2 V all of the time. If anyone is curious the Lifeline batteries are among...

    12V Battery Just Died - Total battery failure

    Your right, it’s not and for the reasons you say, and I’m nearly certain that the whole time we drive our cars the 12V battery is being charged at around 14V which is entirely normal and correct for a lead acid battery, but bad for Lithium. Easy to find out, just check the voltage of the 12V...

    Metal popping noises after control arm replacement

    I woud take it to a suspension shop, not saying lay them to fix it,but pay them to diagnose the issue, and have them show you, diagnosis ought to be on the bill. then go to Tesla. Obviously somethings wrong, the car is not supposed to pop

    MASTER THREAD: Removing marks from white seats

    I would call Ultrafabrics, They nave made Ultraleather for a long time and I wouldn’t be surprised if they are the supplier for Tesla. Ultraleather is impervious to most things up to acetone, acetone will soften it and of course should be avoided. Whatever you try, first try it on an...

    12V Battery Just Died - Total battery failure

    Oh a LifePo4 AKA LFP is a Li-ion battery, there are many chemistries all grouped under a common name of Li-ion. You can “trickle” charge any Li-ion pack, but the charge should be terminated once the pack is full or bad things can occur. However you can float a li-ion battery as long as float...

    12V Battery Just Died - Total battery failure

    Optima’s and some other better AGM’s can easily last far longer, the Prius we traded for our model 3 had an almost 10 yr old Optima battery in it, Optima makes a deep cycle yellow top for the Prius, Prius has odd sized terminals, but anyway the Prius use of a 12v battery is similar to a Tesla’s...

    Battery draw when idle?

    on average I believe Tesla says 1% per day on average, if you only drive 5 to 7 miles a day a regular outlet would suffice easily Nothing wrong with a extension cord as long as it’s a large enough gauge of wire, in your case if you had a 14-50 and an extension cord just turn the charge amperage...

    Rate my planned charging setup

    I have a 60 amp breaker and 6ga wire, to my WC wired direct. I didn’t want a plug as code requires a ground fault breaker for ANY plug in a garage, and the instructions for the WC specifically state to not install a ground fault breaker. I went ahead and maxed the CB and wire, because who knows...

    Rate my planned charging setup

    Back in I guess the 70’s aluminum was allowed in branch circuits to wire houses. There were many fires from the aluminum wiring, one issue is the aluminum expands more when heated than copper and this repeated expansion and contraction caused the wire to loosen where it was terminated, and...

    I bought a small generator for emergency charging of my Model 3

    If there are Mariana’s where you live they usually sell pure gas. Then there is this, it’s actually an App,but isn’t guaranteed. https://www.pure-gas.org/ it’s actually easy to test for alcohol, you need a graduated cylinder, a canning jar will work, put gas in it to a marked graduation, then...

    Paint Repair Outgassing Period?

    Paint will offgas, any plastic does and paint is a plastic. Offgassing is that new car smell BTW. Paint will usually offgas for about a month, but it is weather dependent, in the hot Arizona sun it will finish way sooner than in say the Pacific Northwest. Usually you can smell it, and once the...

    I bought a small generator for emergency charging of my Model 3

    Most small generators have a drain screw on the carburetor, drain all of the fuel from the generator and you can store it for years. If for some reason that generator doesn’t have a drain screw, just let it run out of gas. Also drain the tank. Besides charging your car, a small generator is a...

    Gen 3 wall connector will not connect to wi-fi, how do I make sure the current is set correctly

    If memory serves you do not set the amperage in the WC, you tell it the size of the circuit breaker, yes that determines the output amperage max, but by telling the WC that you have a 60 amp breaker, I believe the output limit is 48 amps. You can tell the set CB size by the number of green...

    Electric brakes? [speculation on brake by wire]

    Prius, it has a “stroke simulator” to give the feeling of brakes. When you open the door on a Prius if you listen you heat the buzz of an electric pump for a few seconds, thats the brake booster pump pressurizing the brake accumulator, the Prius uses a hydraulic system, but it’s electrically...

    Brake Lights.......at standstill

    Our other two cars are a CTS-V, a high performance car with a manual 6 speed, and a Mazdaspeed Miata with of course a manual transmission. Over the years I’ve been rear ended in the Caddy once and then again the other day while stopped at a light a large pickup truck locked up the brakes and...

    Good Article on Tesla Charging and Degradation

    I don’t think that's entirely correct, it’s not just charge level, it’s actually heat that’s damaging, A Tesla apparently pre-conditions it’s battery for Supercharging, meaning it heats the pack uo pretty hot, reason is power will flow either into or out of a battery faster at hot temps,that’s...

    What is the optimal battery temperature for performance?

    I’m nearly certain it’s way uo there at about 60C. High temps like this are bad for longevity, but power will flow into and out of a battery very fast at high temps. Supercharging apparently heats a battery up pretty hot as well. From a longevity standpoint batteries are just like people, pretty...

    Charging time 6.6kW charger for 2019 Tesla Model 3 SR+

    I think charging is about 83% efficient? If so then assume 50 KWH is needed to add to the battery so 54 div by 6.6 = 8.2 hours, but div by .83 to account for efficiency loss = 9.8 hours. I’m not sure about this as I don’t have actual experience, but it should be close unless of course there are...

    Zipcharge looks interesting

    Issue as I see it is your trying to charge an 800 to 1000 lb or so battery with whatever this thing weighs, just by the weight you can tell it can’t have much power in it. One assumes it would be DC to DC because if it’s not as was posted it would be rather inefficient and expensive. Without...

    Cold weather inflatable bed auxillary battery heater

    While I don’t think it will work, inflatable mattresses are available with a built in fan, that reverses so it will suck all of the air out a little bit faster than it inflates. As a Retired Army guy I have slept on an inflatable air mattress, there is NO insulation in the cold. Nothing wrong...

    Need Advice: NEMA 14-50 Sometimes Charges at only 16a

    Pick up an IR thermometer, looks sort of like a gun and you point it at something, pull the trigger and it gives you the temp. They are inexpensive and very useful, can use them grilling, checking tire temps, if you pull a triller you check bearing temps etc. Puts a number to feels warm, hot...
