The rates vary by state and provider. But here is a local co-op's rate page that explains it fairly well: So, let's say that you have a charging facility with 2 350 kW chargers on a 500 kVA transformer. The billing demand is the maximum kilowatt demand sustained for any 15 minute period...

Our local service center used to have these - they may still have one. But lately, mobile service has arrived outfitted in an older Model S with a cage and storage all throughout the back seat and trunk.

I'm sure this will be adjusted, whether through Massachusetts changing the law to allow for per kWh charges, or adjusting price for per-minute charges to equal the recovery needed. You're living on borrowed time right now and I'm sure it will eventually get adjusted. Likewise, I'm lucky in...

The DC-DC converter is only rated at 250A for the whole vehicle, and the little 12V battery can't supply much more than that as a burst. Your best bet would be to get a jump box or perhaps a small battery charger with engine start functionality. Personally, if I got that call today I'd grab my...

Unless you live or work next door to a DCFC charger, you're going to want to minimize the number of times you have to spend going to/from the DCFC location. I doubt you're going to go there only to boost your charge from 30-60%... You're likely going to run it lower and charge to get it...

That's roughly what I saw, too - about 4-5 kW used by the cooling system at the peak of charging.

Here's the question, though - would you pay for it as a subscription? Most manufacturers are saying they'd like to do what Tesla does, but they want to make it a subscription service (either directly or through partners like OnStar). I'd love to have TeslaCam functionality (sentry, general...

I have collected J1772 adapters over time, I had 4 of them - so I used an extra one I had lying around. Different Tesla cars have different charging configurations... Model 3/Y can generally only charge at 48A. Model S can charge at 40, 80, 48, or 72 amps, depending upon which generation...

That's the difference between the blocks just below the requested blocks... that's how much is going into the battery vs. the top blocks which are how much is entering the truck. In this particular case, this is early in the charging session and the cooling system seemed to be negligable.

In the early days of Teslas, the same conversation was had. Tesla offered free supercharging, but it cost money at home. Plenty of people were tightwads and would regularly spend a couple hours, twice a week, sitting in front of the Fremont factory doing e-mail and stuff while they charged for...

This is true - at least for cars that had radar. The FSD beta software disabled the radar and it made basic cruise unusable in the evening on 2-lane roads because the car would keep slamming on the brakes. The FSD team wouldn't even respond, much less acknowledge the problem. They have made...

Unfortunately, without blocking the parking aisle or dropping the trailer first, the only station I could reach was the 350 kW station, so I dealt with it. Watching the voltage vs. current, I could see that the 350 kW station seemed to be limited to around 315A or so. You can see the truck...

Not necessarily, although that can create the ground fault situation. And it should never purposely be done there. Grounds and neutrals are supposed to be kept separate everywhere but a single location. In olden days, this was considered ok, but then they figured out it gives people shocks...

It could very well be that you have some current leaking to ground somewhere - pump motor windings shorted to the case, or some of the control current going through the ground, etc. You can inspect all the wiring, make sure terminals and circuit boards are clean, but if it still doesn't clear...

I had to run to pick up some honey supers from our north apiaries today. Charged to 100%, left my home with the Lightning connected to my Big Tex 14TL 22' tilt-bed trailer. https://www.bigtextrailers.com/14tl-pro-series-tilt-bed-equipment My trip is 140 miles - 35 mi. running 60 on a state...

Once again, you're citing the completely wrong information. He's asking about how to connect the boxes, not load calculations. The web site for these boxes don't always address that.

So here's the concern with sharing the breaker using Polaris connectors - with continuous loads like this, you want to minimize the number of connection points which are typically the places where a lot of heat can be generated (loose connections, etc.). So the CMPs really want you to use a...

Well, in my opinion, they should nuke that requirement that you use the 60 degC table, because modern NM cable is just as good as THHN, but the CMPs don't feel that way. So will it work? Yes. Will it work safely? Yes. Is it code compliant? No, and that means if a buyer's inspector sees it...

That's from the newest code. OP may be using an older code. In my county, they specify 2008 still. :)

I can confirm the pedestrian speaker is not the source of the frunk beeps, I unplugged and tried it "Just in case".
