Currently a Tesla Solar customer and I’m interest in purchasing the home charging system for my CyberTruck. Does anyone have any experience with that or can offer first time experience tips? Thanks in advance.
I have two of them. One hooked up to 80 Amps and the other hooked up to 30 Amps. (I got a signed one for free with 2 referrals.) I definitely recommend having your electrician run wires for the 80A circuit. Don't mess with anything below that. The 30A is fine for every day charging, but there are times when I need a quick charge, so I move into the other garage and use the 80A.The High Powered Wall Charger (HPWC) is capable of delivering 80 Amperes when wired to a 100A circuit. More than one of these can be connected to that circuit for charging multiple cars with the 80 A shared between them. The most current current production S,X and 3 can draw is 48A but older X's can take up to 72. 80A is 19.2 kW for 19.2 kWh delivered each hour. As the CT's will need about 0.5 kWh to go a mile this translates to about 38 miles per hour range added at 80 A - actually probably more like 36 because the chargers are not 100 % efficient.
Because the CTs energy use is appreciably more than Telsa's current largest offering (the Model X) which takes about 300 Wh/mi I speculate that they will probably return to 72 A (or maybe even 80) maximum charge rate at least in the Tri Motor as picking up over 300 miles in a 10 hour overnight charge seems reasonable for a truck with 500 mile range (one usually charges from 50% to 75% or 80% most of the time).
There is tons of discussion on HPWC installation on other Tesla fora most of which centers on how big a circuit one should put it on. Most people settle for a 60 A circuit because up to and including that capacity no separate, lockable disconnect switch is required by the NEC (but local codes might demand it) and that's the most a single Tesla of the current design can take, If Tesla sticks with 48 A rectifiers there is no point to going to a larger circuit unless you plan to charge multiple Teslas. If Tesla installs larger chargers in the CT's then there is motivation to go to heftier circuits. Whether you can do that or not depends on your service and your panels and your willingness to put out more $ for more miles/hr of charging. From this perspective it may be wise to wait to see what Tesla decides to do with respect to charger size (note the HPWC isn't a charger - it is EVSE that feeds the charger which is in the car or truck) in the CT's. You will need to get an electrician in, one who has done EVSE installations before to evaluate your particular situation.
You can go to the Tesla store online and download the HPWC manual.
OP asked generally about HPWC and after digesting that word salad I feel like I need two 100 amp circuits, two HPWCs, and a substation in my garage. I wonder whether it depends on the daily commute expected whether high capacity charging is needed. Does anybody really have multiple 100 amp circuits available? What time is it? [AJ starts typing how to build a watch].Thus it seems to me that if planning for a CT or CTs the most charging flexibility is obtained by putting each of multiple HPWC on separate 100 A circuits which would allow maximum rate charging of two CTs but a much less expensive approach for charging a CT and a 3 or X or S would be to put two HPWC on the same 100A circuit. As I have said before, the is no single correct answer to the configuration question. For more information on the HPWC go to the Tesla store and download the installation guide.
You do if you want to charge multiple vehicles as quickly as possible. Tesla's current and coming (CT) vehicles are considered to be 60 A loads when charging at the maximum rate which is 48A. It doesn't take a PHD in math to be able to figure that you can, therefore, only charge 1 Tesla at the maximum rate from a 100 A circuit. It also doesn't take advanced math to figure that you can charge two at the same time if you dial each of them back to 5/6 of the maximum rate(40A).OP asked generally about HPWC and after digesting that word salad I feel like I need two 100 amp circuits, two HPWCs, and a substation in my garage.
Yes, of course it does. Say you have a single Tesla which you must drive 100 miles per day and that's its consumption is 400 Wh/mi. It will need 40 kWh of juice per day. At the maximum rate the chargers in Teslas deliver a bit less than 48*240/1000 = 11.5 kW say it's 11. Thus you must charge at the maximum rate of 40/11 = 3.6 hrs each night. If you have 3 cars each of which goes 300 miles per day the story is quite different.I wonder whether it depends on the daily commute expected whether high capacity charging is needed.
As the example above showed if you have 12.5 hours available each night you can charge 240 kWh worth of miles with a single 100 A circuit with 2 or more HPWC on it. At 3 or more miles per kWh for S, X and 3 and 2 or a little more for a CT that's a lot of miles (500 - 800).Does anybody really have multiple 100 amp circuits available?
I'll answer that with a little anecdote. I was once in a meeting with Gernot Winkler. As is the case with most meetings it was a pretty boring so I began to wonder what sort of watch the man who was running the Naval Observatory's Time Service Department might wear. So I contrived to drop my pencil and while recovering it glance up his jacket sleeve. He was wearing no watch at all. At a break I ran into one of my colleagues in the hall and reported to him that Gernot Winkler does not wear a watch. "Of course not" he replied without a moment's hesitation. "It's whatever time he says it is." I always thought Bill was a pretty bright guy but I subsequently found out that Einstein had, in response to the question "What time is it?" had answered with "It is whatever time the guy with the clock says it is." I enjoyed working on that stuff. It's fun to be able to go to a party and tell people you are a horologist.What time is it? [AJ starts typing how to build a watch].
