How much energy does it take to supercharge an EV.

Sure, but my figures were running load, that 23 amps.

Probably a 3-5 x inrush. 

Meaningless in an actual usage figure. 

Watt.  Unit of energy

No, a watt is a unit of power.  A watt is a Joule per second, where Joule is the unit of energy. 

Killowatt or KW..     1000 watts, or think of is as 8.33 amps at 120 volts irrelevant to time.

Yes.

Kwh   Killowatt hour           the amount of energy used, in the above  120 volt circuit, drawing 8.33 amps for 1 hour

Yes.

 

Make sense now?

Does what make sense?

 

The Tesla charges are throwing hundreds of amps at 400 ish volts. 

Impressive, but that's why the numbers are so big.

Definitely a lot of power, agreed.  

See comments above.

Missing the point...it's not just usage but load on the system at a given time.  His home usage is accurate as is his load.

Maybe you should change the thread title to “How Much Power It Takes to Supercharge an EV” rather than energy.  These terms are not interchangeable.

True.

They are not the same thing

Many dc charge locations are using battery systems to shave demand charges on highly utilized superchargers.  Even competing manufactures are using Tesla battery packs at their stations.  Also it’s pretty much impossible for all EV’s to pull max kw’s just cause of charge ramp ups and down based on  EV battery capacity.

Wonder when and how they’re going to start collecting road taxes on EV’s. Should be higher than a properly powered vehicle too

My state adds cost for registration.  Feds will likely just tax the rich more or borrow the shortfall

That goes against their subsidy bullshit.  It would be really easy to adjust tabs by not only value but weight.

When you vote better.

The budget will balance itself in 2035 when their is nothing to buy but EV’s in our Dopia Utopia.
 

You not get the program?

Perhaps you are working with the older version of Newspeak?

Easier to explain with 200,000 less words to use.
