One thing that seems to have been forgotten in the discussion, is where is all the additional electricity required for these chargers going to come from?
If you look on the Gridwatch website, you will see that on some particularly cold winter days, we are already getting close to maximum grid capacity.
Can you imagine the chaos that would ensue, having 1000s of electric cars vying for power, you may well be limited to night-time use only, when demand is lower.
It takes years to build a power station and the government is not even thinking about this issue at the moment.
Also, most houses have a limited power input capacity of around 25Kw, my house is only 15 Kw (ie 60amp main fuse)
Nobody will be fast charging from a domestic supply!
Whilst i applaud the concept of electric cars, i don't think the long term affects have yet been thought out.
