So I have a power supply that produces 75A constant current at 13.5v.

My alternator runs at around 14.7 in this weather, around 14 in the summer, it is a factory 90A alternator.

If I wanted to give my cars electrical extra charging current on my drive way, could I connect my power supply while running the car to have a total of over 150A going to my batteries and amplifiers? Or is there a chance of reverse current flowing back into the PSU because the alternator produces higher voltage?
