Re: Full charge in 10 minutes?
Oh, it's so nice to be patronised…
Your maths is still off as you asset that charging the car is faster than filling the tank: wrong on both accounts - it takes longer and you need to do it more often. More importantly, taking as least twice as long to charge as to fill means needing twice as many chargers as fuel pumps to provide the same capacity. This will make a big difference as the number of electric vehicles picks up, currently tiny in most countries. Here in Germany we're already starting to see limits on household charging points because the grid can't cope with lots of them on the same street. Again, you have to provision for the maximum draw.
It also provides the lie to your assertion that 300 kW lines aren't a problem. I routinely see lines of cars waiting to fill up at petrol stations: batteries will be quickly flattened if the number of electric vehicles gets anywhere near that of petrol cars.
But it's also nonsense to play hydrocarbons against electrics as they are undoubtedly a much better form (energy density, flexibility) than batteries.
