I have a caravan with a 75/15 solar charger and I was wanting to know if I can disconnect the solar panel and connect it to car while I drive as a D.C. D.C. Charger?

75/15 as a D.C. D.C. Charger
It is a step down converter so it needs 5V more on the PV entries than the battery to be charged to initiate. Your car will only reach that if you have a 24V system, your alternator is faulty or the battery in question is drained beyond sensible levels. It then stops charging if there is less than a 1V gap between both sides which is no good either for fully charging.
So in theory yes, in practice not so much. What you want is a battery booster for fast charging or something out of the Victron Orion series if you have little more time on your hands.
