-In principle, it would be possible to keep the DC/DC converter on permanently, or to add a second, smaller device that feeds the 12V grid while the car is idle. An additional device could be optimized for prolonging the battery life by doing all that ctek voodoo of different charging phases at different voltages.

+An additional, small DC/DC converter could be optimized for prolonging the battery life by doing all that ctek rituals of switching between different charging phases at different voltages. I am imagining to use a small 15V output DC/DC converter module as a power supply, followed by a microcontroller circuit that fine tunes the output voltage.
 With a permanent power supply, the battery is not drained any more while the car is idle, and it's size can be substantially reduced.
