I noticed that the blue LED for the 12V charging now comes on every 24h to maintain the aux battery, so apparently Nissan knows of the problem and has updated the firmware to increase the aux battery maintenance. Huh. The DC-DC converter comes on periodically when the car is off? We had a discussion about Leaf 12V batteries a year ago: https://www.mail-archive.com/search?l=ev%40lists.evdl.org&q=subject%3A%22%5C%5BEVDL%5C%5D+Leaf+12+v+battery.%22&o=newest I suggested that EVs should not have house batteries and instead the DC-DC should always be on. The main counterargument seemed to be that the high voltage system should be isolated for safety when you're not driving. But now you're saying that the software turns on the HV system periodically to charge the house battery. This seems even less safe than having it always, for example if someone is working on the car when the HV system turns on unexpectedly.
