It may not be as simple as just dropping in a new charger itself and updating the firmware. If such is the case, it may not be financially feasible to make the swap.
The battery would not need to be altered in any way, since it is already capable of charge and discharge rates well above 6.6kW (80kW max discharge, at least 30kW charge via quick-charge/regen)
If the cables leading from the charge port to the charger aren't up to snuff, it should be a relatively simple matter to swap them out. I don't think this is likely since the J1772 connector is rated 80 Amps, so the wiring should be at least that. It's possible it isn't of course - but it should be a quick fix since it's a single run from port to charger.
The upgrade can almost certainly be done in under an hour if the cable needs to be swapped, half an hour if it's just the charger. Well within "while you wait" duration IMHO.
