Unable to drive for 6 months

Good evening all,

I did a few searches of the forum and couldn't find anything that matched my situation. I am leaving my 2013 ED for work for six months. While I trust my wife to spin it around town every week or so, in the event she doesn't, what precautions should I take in the event life happens etc? Seeing all the posts about the 12v dying and the HV battery bricking has certainly terrified me. Should I get the 12v charger and keep that plugged in while it's not driven? What about the HV charger?

Thanks!
