I just got a 2015 i3 REx a couple of weeks ago and I keep getting a message when I turn on the car that says “increased battery drain while parked or something like that. It’s summer and we’re in extremely hot SW Florida, so I’m wondering if it’s from AC — I try to get the car cooled for our 2 year old and 4 year old before they get in.
Anyone know more about this or do I really just need to take it to a service center?

Hi, I believe it is related to the heat and the fact that the battery thermal management will try and cool the batteries, and if not plugged into a charging station it will drain from the batteries, themselves.
It's always best to be plugged in if you can, especially with a level 2 charging station. A level 1 will help, but the batteries will still drain, if just a bit slower.
(ABC--Always Be Charging)
i3 BEV--2019 8 miles ;-)
13 REx--2017 29,457 miles onto CPO somewhere 330e --2017 27,500 miles, RIP I3 REx -- 2014 41,191 miles RIP RAV4EV -- 47,500 miles RIP Active E--26 months, 28,000 miles RIP
Its also hot here. Never get this message. I would at least call and ask.
Also, there is no need to use a Level 2 EVSE unless you need the car to charge faster. Level 1 is all I have used for 3 years now. Drive it every day, 40-60mi per day, 180mi every other weekend.
Level 2 charging is not required to cool the car down, neither is Level 1. The cooling system was designed to work, plugged in or not. Works great. Car cools very quickly as it is a small car. Do it all the time. Never get message. I would call to check just incase it is something serious.
From what I've read most people that get that message find out it's the 12 volt battery that's about to fail. It's a small battery and they don't last long in the heat. Best to get it checked out by the dealer and within warranty it will be replaced for free.
