Yesterday Tesla announced that some of their superchargers are now open to non-Tesla cars, at the same time, on the Tesla Supercharger map a new Tesla charger installation, due Q3 of this year, was shown at Judds Lane in Coventry.
Doesn't say at the Arena, but would make sense, especially if it were in time for the Commonwealth games, and doesn't say if it will be open to non-Teslas.
