My GT can sit unplugged with the LVB SoC at 60s% for hours or days and the DC/DC converter will not kick in to charge it. Then immediately when I plug in the charger it starts charging both the HVB and the LVB and I can see the LVB SoC going up.The LVB doesn't necessarily get charged every time the car is plugged in. The car monitors the voltage of the LVB, and the DC/DC converter kicks on to bring the voltage back up when it gets low. This can happen whether the car is plugged in or not.
I am almost sure that the algorithm prefers to charge the LVB when the car is plugged in to external power. I don't know if the HVB is charged for 22 hours (say it is plugged near empty to a 240v 16amp charger) if the DC/DC converter will condition the LVB for 22 hours as well but it is worth a try.
