As stated in the image. In this case no action is taken for the 12 Volt accessory battery. It is left to discharge Endlessly. This is an even worse case than the minimum attention given to the 12 Volt battery when the traction battery is above 40%.Don't forget this part: As long as the HVB is at 40% SOC or higher.
What have stated in my comment that is not possible?This is an out take from my post (#16) You should read all of it.
I don't think you're testing it properly because you're trying to tell
me something that's not possible, unless the car has an issue.
The Hybrid/EV Powertrain control module (HPCM2) will check the 12V battery every 4 days (2.5 to 3 days) and if the voltage is below a threshold of 12.0 may activate battery maintenance. If the high voltage battery state of charge is greater than 40% and the propulsion system is not active, Hybrid/EV Powertrain control module (HPCM2) will send the voltage set point to the engine control module (ECM). The engine control module (ECM) will send this to the 14V Power Module. Battery maintenance mode will charge the battery for 45-90 minutes..
You say "not possible" without saying what is possible. Answer the question!So you don't drive the car ? Unhook it and charge it with your battery tender.
I don't understand why you would even own a car if you never drive it.
Good guess for moderate temperature where thermal management is not in play. Even so you ignored the SOC part of the question.12.4 to 12.6 if you start with a 12.6 or better SOC. I don't think you're testing your battery properly to get the reading you claim.
