How much time will it take to recharge these batteries? With energy
coming from what energy sources? How are national power grids going to
cope with the load of millions of EVs requiring dozens of kilowatts of
electrical power to get fully recharged in a practical amount of time?
Battery capacity (= car range) is a serious issue for electric cars in
the short term, but unfortunately, not the only one in the medium to
long term.
