The voltage is directly proportional to the Amps. The current will not flow if the voltage of the battery is more than the charge rate. The higher the voltage difference between the battery and the alternator then the more current will flow.
So by having a higher alternator output voltage, allowing more current to flow, more water will boil off...
I = A/E
I learnt that during my apprenticeship quite some ago, and haven't forgotten it, yet.
