Installing EV Charging Units in Petrol Stations

Petrol stations have various strict requirements regarding their electrical installations for obvious reasons. How will adding a MW size supply for a few high power chargers be dealt with, separation? Will earth leakage currents be a problem? If I remember correctly the reason the canopys are so high is to move the lighting into a different zone.

    I ought to try and work out for every 0 to 60 in 5 seconds, by how many miles does that burst reduce the nominal range.......


    Tesla Model S "Plaid" does 0 - 60 in 2 sec with 1000 bhp peak. So that is 750 kW for 2/3600 of an hour = 0.42 kWh. Ordinary Model S takes 3 sec with 670 bhp peak = 0.56 kWh.


    Range is about 400 miles with a 100 kWh battery so that is 0.25 kWh per mile.


    If the acceleration is linear, the average speed during the acceleration phase is 30 mph. In 2 sec that gets you 30 yards down the road, so I think that we can ignore that.


    So the answer is that each burst of 0 - 60 flat out loses a range of about 2 miles.


    I think that such fierce acceleration on the road would be as unpleasant as it would be dangerous.
