It will only depend on how the charging option is configured.
Whenever solar cells receive light/sun to charge batteries
Only when vehicle is switched off / stationary and sun/light is available charge batteries.
In my opinion option 1 makes more sense as the APTERA should charge whenever sun/light is available for charge.
This way while driving during daylight hours the batteries and solar panels would both provide power resulting in less drain on the batteries while driving.
My solar system at home works on the same principle - in the early morning the batteries carries the load until the sun is high enough providing enough light and the solar panels can carry the load. Then rest of the day solar panels provide the power while the batteries are also being charged. Late afternoon when the sun dips it once again is a combination of solar and batteries until the sun is down - then once again only batteries.

It appears it will always charge except by solar while on a rapid DC charger
