“75 kilo watt hour charge in 1/6th hour would require a 450 kilo watt source.”
Where did you get that. Tesla is advertising 200 miles in 15 minutes. That would be 50 kwhr in 1/3 hour or 150 kw.
Their superchargers are rated for 250 kw. Others have chargers rated even higher.
I have a Tesla, so I’m not a naysayer. That said, the questions that remain about the practical hurdles for electric cars are legitimate and have not been fully addressed yet.
As you’ve pointed out, the performance characteristics of electric cars is remarkable, given the instant torque. I love the performance of my Tesla. However, I’m not convinced that I’ve done a great thing for the environment by buying one.
“Where did you get that. Tesla is advertising 200 miles in 15 minutes.”
They also say charge to 80%, don’t go below 20%, avoid using fast chargers unless necessary and avoid charging a hot battery when possible.
