Yeah if you get a feel for how quickly it charges, I'd imagine you could just put it on any old timer, as long as its using the 120V charger and not something with more balls.
Also, could use one of those little solar panels to keep the 12V guy up if you're parking it outside.
The solar trickle charger for the 12V is a great suggestion, Papa. Now that you mention it, I installed a lighter socket connected direct to battery on a '13 for just that purpose, the owner got frustrated after being towed in for "duh" codes after an unsuccessful jumpstart. He just parked it with a south facing and tossed the panel up on the dash, as far as I know it worked well for him.
Regular appliance timers will work okay with the 120V charger, but the timer needs to be a good one that can handle the high current draw. Nissan even posted a bulletin specific to the 120V chargers about people burning up the plugs with poor connections to the house socket. Not that it's fatal to the charger, any good electrician can cut off the bad plug and put on a new one, but Nissan won't
warranty that. Still, the SOC cutoff is much less hassle for vehicles that have it. I did think about building a gizmo that would cut off house juice to the charger by optically monitoring the flashy-lights on top of the dash, killing it about an hour after the third lamp went blinky. Trouble was it would have needed UL approval to interface with house wiring. It could have also been done by interrupting the security circuit that tells the car the charger plug is fully seated, but that could have had product liability consequences if it failed and stranded people with an unchargeable car. So I never built it.
