How long does a full charge last?

The EPA rates the Volvo EX30 at 253 miles combined. Cold weather, motorway speeds and a loaded car all reduce that; the EPA number is a standardised test, not a guarantee.

Does this include charging losses?

Yes. The EPA's 31.1 kWh/100 mi figure is measured at the wall socket, so the energy lost in the charger and cabling is already in the number. No extra efficiency factor is applied.
