Put the vehicle in sport mode so you can see the tachometer and rev the engine to 3-4k until you see power flow being sent to the battery. Hold the RPMs at the point where the charging is operational until the desired charge level is achieved.

It also occasionally recouples during idle to temporarily charge for a few seconds so that the battery doesn't run down too low.
So this is interesting are you revving the engine in sport mode while driving or in neutral?

As I mentioned before, I already knew that when the car is idle, it will automatically recouple the starter/alternator and charge the battery up to the 2nd blue bar only...so revving to 2-3k+ rpm in park just is the same result but done manually without waiting for the car's computer to manage it.
Were you able to charge the battery with your method to the 3rd bar? Full?
