Re: Cost of installing charging units for electric cars?

I can only advise in relation to a Tesla Model 3.

Maximum rate of charge A/C (alternating current) of a Tesla is 11kWh. It is almost certain that the system you are considering will be A/C. D/C is much faster and more expensive to install. Ionity and Tesla Superchargers are DC and charge at rates of 130kWh and more.

My Tesla Wall Connector (not charger, the charger is in the car) cost CHF500 and the installation to our garage through existing channeling of a 3-phase supply from cellar to an external garage about 4 metres away. Including, mounting the unit etc was an additional CHF1900. So CHF2400.-.

11kWh adds 65kms per hour of charging. A public charging point is likely to be less than this. Maybe 6 or 8kWh. Though at 6K a pop they really should be faster.

Also will charging be free and will the bays be exclusive to electric vehicles?

I'm very encouraged that communities are thinking this way. It's the future!
