I’m sure the electricians on here will provide some educated advice. However I suspect that your choice of cable size, routing and length are going to come in for some questioning.
Even without knowing very much about electrics, if you’re going to want to charge at 7.2kW and your supply is above 230v, that cable would need to support 32amp for a sustained period which means you’re going to need a 40amp fuse.
