According to google, it's around 3,000 watts. That's a whole lot more than watching TV or lights left on. More like a clothes dryer or an electric furnace.

Whirlpool dryers typically require 2100 watts of energy for one hour. (2.1 kwh)

So 90 minutes of drying.

Level 2 charging (240 volts 16 amps) is capable of 3940 watts per hour. (3.9 kwh)

Solution to not overloading the grid? Don't charge the car and run the dryer at the same time?

I could look it up, but, I wonder what the new Tesla semi tractor charge rate is? I bet it's a whopper!

20ldman,

No idea. But a typical daily commute here uses about 6 to 8 kwh of power. So on a 32 amp 240 volt charge station like the one in the garage then it takes about an hour.

And if it is a 12 amp 240 volt charge station like the one in our driveway it takes closer to 3 hours. Pics for clarity.

Megachargers can provide 750 KW. But the truck can actually charge faster than that. But the existing megachargers that pepsi has installed are 750 KW.

The only issue is that your Li-Ion battery is only good for something like 25000-30000 charges. If you are recharging every day, you are going to get shocked when you hit that number and you need to replace your batteries.

The Li in my RV can supposedly last a lot longer if it's not run down to 10-20% or so before charging. Maybe a car is different.

I have no doubt battery technology will improve, the grid will improve, and all these doomsday predictions will fade away. And then there'll be some other new technology to complain about. [emoticon]

Its cycles. Not charges. So 2 X 50 percent charges is one cycle. And I think its 2500 to 3000 for NCA batteries and higher for LFP batteries.

Can't wait to see one going up a grade at highway speed.

It’ll be awhile for us as we won’t be doing the grapevine till March of 2024. We’ll be hauling our little trailer. Hoping that Harris ranch has their campground in by then. We’ll be on the homebound route by then.

This is a Megacharger. There are only 4 of these and they are all the same (although one is still under construction). This one is at the Tesla semi factory in Nevada. The others are at various pepsi depots.
