Do some simple calculations for yourself before you psot something silly
What simple calculations are you referring to? Lithium batteries take 1 hour to charge. The Tesla simply uses a large array of lithium batteries. If one charge worth’s of electricity flows at 110V in 8 hours, the same amount should flow at 880V in 1 hour... providing you can safely transfer the electricity. My question, and I worded it as a question, (even adding “and this might be in the category of just plain ignorant”) was whether that could be done.
