How the 12V battery gets recharged
In a petrol car the alternator charges the battery whenever the engine runs. In a Geometry, a DC-DC converter tops up the 12V battery from the main pack, mainly while the car is switched on or plugged in. Parked for a fortnight in a hot car park with the alarm and telematics awake, the small battery can fall below the level needed to wake the car, even with plenty of range showing.
