At my parents we had the "two cars, one AC circuit" problem (plug both cars in and the fuse blows) so we used timers to alternate power between the cars. That worked better than you might think, although the timers froze up occasionally and the fuses blew again

Eventually we just punched more wires through the wall and now can plug 3 cars in simultaneously.

Of course that was also about the time everyone moved out; now there is only one car and my parents don't go out when it's cold anyways...
