Re: "simple but elegant"
a charger with multiple leads
Of course, and is the thing I imagined when I said "one per space". You don't need one "station" per space, but realistically you will need (nearly) one "connection" per space. Depending on car park configuration, one charging station could probably serve between three and six parking spaces. Any more than that and you have trailing leads (two or four would be better) which could be a hazard.
