I have been watching this for awhile now and ever since I had the P5327 recall done (which I understand to be some software fix for the relay in an electronic brake booster) I've noticed (according to LeafSpy Pro) that my car is spending a lot more time charging the 12 volt battery, that is the DC/DC converter spends way more time outputting over 14 volts (more like on an ICE vehicle) than it did prior to the update. It also has been colder here, but not below freezing until very recently. I know TomT, Nubo, and others here speculated that the software update may cycle the relay more in cold temps to keep it from freezing so I'm wondering if part of that was reprograming the charging protocol to keep outputting higher voltages to support the cycling.
Has anyone else noticed this behavior (assuming you run LeafSpy Pro all the time or otherwise monitor battery voltage)?
