JCT - are you saying that the only time the 12V Battery gets charged is when the ICE is running? My journeys are alsmost all short, local ones on EV only and I have already had one flat 12v Battery incident.

...........However, I have noticed that, when set for EV only operation, the car does switch to HV for short periods. Is this to put some charge into the 12V Battery?

The 12v Battery is charged from the traction Battery, but only after the 12v has fired up the computer, which activates the traction battery…. This is why a dead 12v is a pain.

the engine charges the traction Battery, but is only started by the traction battery…
