Tesla's new charging network will halve waiting times

Tesla Inc. is updating its charging network to halve typical wait times as the Model 3 fleet grows larger and rivals like Porsche ready their own powerful infrastructure.

After doubling power at Tesla’s stations and vehicles preheating batteries ahead of arriving at a plug, charging times will drop to around 15 minutes, the electric-car leader said on its blog.

The problem still remains, where is all this peak power coming from? It is fine while the electric car market is small, but with some half decent adoption rate the power grid will need to have major power upgrades/changes

95% of the time a slow 8 hour charge overnight during off peak hours at home will suffice. I think these fast charges would only be used when the car is being used on long distance trips.

You're only time shifting the problem. If 95% of people are plugging in overnight, you've just created a massive peak power demand around the time people get home. Which is already the biggest power peak (start of dinner). So now you need to create algorithms/programs to ask car chargers to shift their charging times, which again just shifts the problem. At least in the middle of the night there is usually spare capacity and the pattern of use will be fairly consistent so it's more manageable.

But you still needs tons of peak power to drive these fast chargers for the 5% who need to fast charge. Just think about it like this - six of these chargers is the equivalent power as required by a modern day sports stadium. So whatever infrastructure you need for a stadium is essentially what you need for just six chargers.

Tesla already has location-aware scheduled charging...

Grids are changing to adapt to renewables anyway, so it's pretty much happening in lock-step with the increase in EV transportation.

Renewables aren't good for peak demand, except Hydro of course.
