Fisker's Tesla competitor has 400 mile range and charges in just 9 minutes

I am curious, can someone explain how is designed a 600 kw cable used to charge an electric car that have a 90kw battery in 9mn? (I am not interested in batteries technologies).

I am interested specifically in the cable technology and the apparitus from which the cable takes its power, and where does this energy comes from, is it from a direct connection to distribution sub-station?
