The SAE Combo standard doesn't affect home charging. It is for DC fast charging only, whereas home charging with Level 1 or 2 uses the standard J1772 plug. The SAE Combo is essentially an addition to the J1772, so a vehicle compatible with SAE Combo will accept J1772 for Level 2 home charging and SAE Combo for DC fast charging. It is CHAdeMO that requires an additional charge port.
