Realized I didn't really answer your question fully. Again, I don't think my experience is going to be helpful to you because you are planning a residential space and I built a garage designed to charge 3 BEV (MX, Rivian and CT) of which I have only the X at the moment with doubts as to whether...

Yes, it was. As I said in an earlier post I'm afraid to look at the actual bill but the average cost for PV in Virginial is 2.88/W and I've got a 13 kW system so that would be 37K USD before incentives. Powerwalls are $8,500 USD so 5 of them comes to $42K before installation and incentives so...

Because they are the ones with the money! (nod to Willy Sutton).

Apparently someone misinterpreted my post as saying it’s OK to leave a battery at 0%. It doesn’t say that at all. It is my policy to stay out of the bottom 20% if possible.

Very important that people understand that leaving a battery at 0% may not damage it at all (e.g 0% set for 3.0V) whereas letting it sit at 0 V will most probably destroy it.

My comment was based on my recent experience with building a charging carport i.e. a shelter in which I could park and charge my BEV from the sun without any grid connection. It transmogrified into what the contractor starting referring to as my "garagemahal". It has 45 panels (13 kW) and 5...

A "bit". Have you run any numbers?

Yes, the contradictions here are plain. To beging with nothing was said about this in the video. It was about battery production by various manufacturers. In the second sentence it talks about handshaking with its charger which makes it sound like he's talking about a car and then in the same...

No. Current Tesla architecture is 400V. If you intercepted the com link between a SC and a current Tesla and asked fo 900 V and the charger complied the battery would draw way too much current and its protective fuses would blow. The motors are designed for 400V. The insulation is suitable for...

HPWC in use. Located so as to keep cable off floor: Same HPWC with wand stowed in internal "socket". No electrical connection: WallBox Pulsar stowed. No internal socket:

I doubt very much that your land lord would want to do that. It is more probable that if you wanted to use this feature you could get around the 200A limitation by installing at your house two or more HPWC on individual 60A breakers. The inspector looking at your panel sees 120A of vehicle...

The Tesla HPWC can communicate with each other through WiFi. I'm not sure how much of this has actually been implemented yet (simple sharing has) but if your landlord wanted to offer charging at a flat rate he can put individual chargers anywhere (i.e. in each individuals house/condo/appartment...

Hardly. It's job is, first, to detect that a car is connected to it. This is so that it will not energize if the plug is not safely buried and locked into a vehicel charging port and disconnect if, during a charge, the vehicle somehow gets disconnected. Second, it detects whether the cars...

I think the video makes the answer pretty clear. There isn't enough advantage in going to 800 V to make it worth while and the marginal advantages in going to 900 do not add enough to make 900 worth while either.

As the ancient philosopher said "The more I know the more I know I don't know".

I forgot to respond to this last bit. Power is the rate at which energy is transferred. It takes 482 Watt hours (energy) to move my car 1 mile. Thus if I drive (and must replace) 100 miles per day (the average American's round trip commute is 37.6 miles per day) I'll need to replace 48200 Watt...

Yes The thing installed in your house is not a charger. It is an Electric Vehicle Supply Equipment (EVSE). All it does is communicate with the car and the house wiring and connect them if everything is appropriate. The charger is in the car and it is a 400, 800, or 900V charger using 240 V a 24...

That's akin to asking whether the cost per potato or the number of potatoes one buys is more important in determining the size of one's bill. The battery charges by moving ions and electrons from cathode to anode across a potential (the cell voltage ~ cost per potato) through, resepectively...

I don't know anything about the baking industry but I do know something about brewing. It takes a brewery years to develop a new beer worthy of being included in its portfolio. In the brewing industry there is plenty of tasting along the way (that's why the fermenters and lagering tanks have...

It's terrible as you might expect understanding what it is. It is the car's estimate of what is left in the battery relative to the 0 mark divided by the rated consumption. How accurate it is depends on haw closely you match rated consumption in the future and actual consumption can vary quite a...
