Q8: How long to fully charge a car?

To know how long to charge a car, you need to know the OBC(on board charger) power of the car, the car battery capacity, the charger power. The hours to fully charge a car =battery kw.h/obc or charger power the lower one. For e.g, the battery is 40kw.h,obc is 7kw, charger is 22kw, the 40/7=5.7hours. If the obc is 22kw, then 40/22=1.8hours.
