Does it need to be plugged in 24/7? New owner, sharing charger with Model S.

As mentionned by some of the guys, active cooling when returning from a drive with the roadster requires 220V.
I've never seen the front fans quick-in on 110V to cool down the pack.

I charged exclusively on 110V the first year I had my Roadster. I can confirm that the fans do in fact kick on and the car does do active cooling at 110V - it just isn't nearly as frequent and doesn't happen immediately upon plug-in as it does with 220.
