I had to check your numbers on that. So using rough math round numbers, a typical home uses about 11,000 kWh per year. So that comes to about 1.25 kWh per hour. A Tesla needs about 125 kWh for a full charge. So rough math, assuming it takes 1 hour to charge, one fast charging Tesla uses the same amount of energy as 100 homes during that hour - on average.
I am totally open to correction because I did this math quickly and used quick search results for the data.
And, with slow charging, the typical secondary distribution transformer in your neighborhood can handle four EVs. The transformer serves 10-12 houses. To serve more homes, you need larger transformers. But then you have wire capacity limits from the substation to the transformer.
The dirty secret is that the current power system cannot support the wholesale changeover to EVs. It was designed for the days when you had lightbulbs, a vacuum cleaner, a toaster, a dishwasher and a clothes washer.
Last year we drove our EV 26K miles, with 16K of those miles charged at home. That took 4,900 kWh of charging at home.
The rest of the house used 15,900 kWh last year.
Details: According to the inverter telemetry of my solar equipment: my electrical panels used up 20,800 kWh (ignore from now how much of that came from solar panels, how much came from solar batteries, and how much came from the grid). Subtract from that the EV charging and it was 15,900 kWh to power my all-electric, two-story, 2,300 sq ft home in warm climate Alabama. That's with a variable speed heat pump to cool and warm the home (with heat strips when the weather is too cold for the heat pump), and with a hybrid water heater that runs at 380W to warm the 50-gal water tank (and during the warm months I divert the cold air by-product from the water heater into my HVAC intake to utilize that free cold air).
it may be that. It may take a thousand homes to charge EV if all 16 stations were active. I wish I could find the video. It was either on X or Tik Tok
