The worst part is they just need a couple dedicated normal outlets in the parking section. Most people would be fine charging their car off a tradional 13A outlet. 1.5-2 kWh would result in 6-8 kWh over night. And at an avr of 0.2kwh per km we get between 6-8km/h so over night that should be 30-50km which is much more than the average city travel.
