There have been several different observations and suggestions on the discussion board about dealing with battery conditioning when the car is sitting at your house in hot weather. This last one by plj leaves me confused. As described in that post, the battery conditioning came on when the car was plugged in; but when the battery wasn't plugged in, with the same temperature and with the SOC over 30%, the conditioning didn't activate. It wasn't clear to me from the post if the car was actively charging but I'm thinking it was. Some posts have said that if the SOC was over 30%, the conditioning would come on even when the car wasn't plugged in. This seems contrary to plj's experience. Some have said the conditioning would occur in this circumstance but at a lower level. True?
I will soon be on TOU so would like to charge only at night but have the conditioning available in the day time. I also subscribe to the idea of reducing the number of charging cycles by recharging only when I get down to around 20-30 percent SOC and using Hill Top Reserve to limit the top end. So I'm very interested in knowing for sure if conditioning will occur if the car is unplugged but over 30% - the status of my car most of the time. I take plj's post to mean it might not.
A clever post by SparkE - viewtopic.php?f=21&t=6754&p=22229&hilit=vacation+storage+plan#p22229
- suggests a method for keeping the car plugged in but with only a minor charge occuring, by setting up the car's programming to only charge for 15 minutes a day using 110. While a bother to switch the plugging schedule and the cables back and forth, this would work for my charging program if I knew for certain that plugged in but not charging was sufficient to cause conditioning to occur. But I'd prefer to keep the car unplugged when I don't need a charge, if I can rely on the conditioning to occur with the charge over 30%.
Sorry for the lengthy post. Any clarification is appreciated.
