You might consider installing one of these Sigma charging centers. I just installed one and used a spare circuit & fuse in the converter panel.
Running wiring around a ceiling isn't as hard as one might think. I've done lots of it now. Take down anything from the ceiling that can provide access into the ceiling cavity like skylight bezel, AC vents, lights, speakers, etc. Use a coat hanger or electricians fish tape (available cheap at HF). You will probably have to leapfrog from access point to access point. You can go up and down inside walls if needed to run far enough horizontally. You can also cut small access holes in the ceiling inside cabinets, fridge compartment, etc. Use a sharp utility knife for cutting luan. If there is wiring on a wall already, there is a chance if it goes up into the ceiling space, you can fish another wire or two down in the same hole. I've done that a few times.
The hardest part about running wiring in a ceiling cavity is that it is very cramped and if you have big hands, you may not be able to reach in very well. If you have one of the new arched ceilings, they are really cramped, especially at the outer edges.
Watch out for sharp screws too. The factories like to use lots of sharp tipped screws in ceilings and you'll even find wiring laying on top of them.
