charging points are becoming more common
It takes around 5min to refill a tank with about 400mile range, diesel or petrol. An exceedingly high powered charger takes about 1/2hr. Just on that basis number of pumps would need multiplying by 6 and some one could still find themselves hanging about near 1/2hr before they could plug in. That is with ~100kw charger, 20min with 150kw. Work out what 20 of those would need in total. Probably getting near what a rather small subs station could supply. This would need an HV supply to bring the current down.
