I put my Roadster 2.5 into Storage Mode in July and now it's down to 12 Ideal Miles. Is this normal, or should I start looking for a problem? I leave it plugged in to a ChargePoint system in my apartment garage through a CAN JR adaptor and changed the mode from Time of Day (formerly 2am) to the normal Charge at Plug In. I have the Tesla Motors car cover on the Roadster, and the vents are aligned such that they should allow air flow properly. I thought that Storage Mode maintained a 50% charge, but searching the forum here I see that it's really about 20% only. 12 Ideal Miles seems to be less than 20%, though, at least according to my math. The car had at least 50% change or more when I stopped driving it daily, so I'm a bit alarmed about the fast drop in charge over just a couple of months, but comments in the forum seem to indicate that the charge level can drop fairly quickly in Storage Mode, even when plugged in all the time. We have had unusually warm weather here in Seattle of late, with the smoke from Pacific Northwest forest fires covering the skies. Is the charge loss due to heat and/or cooling? I have noticed that the ChargePoint system didn't seem to work well with the Time of Day mode. It seems that the ChargePoint charger wants to shut down after the first cycle, or at least I never noticed it catch the second cycle when parked over a long weekend. I'm not really sure what's going on there, but I used to plug in at least 5 times a week, so it wasn't much of an issue. The meter shows hundreds of hours now, so I assume that it hasn't cut the power after a single cycle. I also hit the Top Off button inside my Roadster after noticing the low Ideal Miles, but I haven't pulled the car cover to check again since then. Maybe it's time to install OVMS! p.s. I stopped driving the Tesla only because the license tabs expired, and Seattle rates for a 2011 Roadster have increased to $982.75 per year.
