    …Three-phase power to their individual parking spots – higher cost, faster speeds, exclusive access? …

     

    I would advise against a high powered, three phase supply to individual parking spots. Writing as someone who has been driving electric cars since 2009, I can tell you that people think they need high powered, faster charging before they get an electric car because they are still doing petrol-thinking. When you don’t need to go out of your way to fill up and spend many hours at home, you can quickly adjust to trickle charging top ups at home and find they are plenty. Hardly anyone needs high power charging.

    I have access where I park to a single-phase 32A supply (7kW) but I can rarely be bothered to get my portable 7kW charge cord out of the car to use it. Instead I use the 10A (2.3kW) cord that I leave in our carport plugged into an ordinary power point ready to use. 10A can add about 200km of range overnight. [15A would add 300km. 7kW/32A single phase will fill any car overnight no matter how large or depleted the battery is. 3 phase is overkill for home charging.]

    Marbles, if you would like to talk all this through by phone, you are welcome to send me a message via this site and then we could arrange a time to chat. Without talking, it is hard to know what level of understanding (or misunderstanding) the other person has. I could get a lot more technical or start a lot more basic. Depending on the details of your building, there are probably some options that can be crossed off the list pretty quickly, saving some potential for confusion.
