Slight thread drift, but I was talking to a friend who has just got a Tesla Model 3, and some of his answers makes me doubt if UK plc car fleet can ever go nearly all EV as Boris would like.
For example, in order to maintain the battery charge and condition, he is told to keep it plugged in all the time ('tethered') when it is parked. If he parks it at an airport for a 2 week holiday (some chance at the moment!) he will come back to a severely depleted battery and the first thing on leaving Heathrow/Gatwick will be to find a charger. Is this the case with all EVs?
In other words, rather than just having x number of chargers, won't there need to be almost 1 charger for every EV so that every time an EV is parked up it is plugged in having it's battery conditioned and ready to use whenever the owner wants? With a block of, say 30 flats with maybe 3 chargers, if three owners are plugged in all the time to condition their batteries, how are the other flat owners supposed to charge up unless there is almost 1 charger per flat? With an ICE, we fill it up with fuel and that full tank is ready to use whenever - we don't need to keep the fuel hose in the car whilst we are not using it.
Is this the case with all EVs? Genuine question.
