You can buy charges for two vehilces although I think they simply split the charge between the two outlets rather that charge the vehicles sonsecutively. They are expensive being really designed for commercial premises and don't qualify for the, soon to disappear government grant.
If by some chance you really need to charge two cars at the same time your best bet is probably to use the granny charger in a 13 amp socket for one of them. A least that way one of the cars is being charged at the charger's maximum rate rather than at 50%
