I don't understand how this would happen, unless you made a mistake in your math, or your procedures. (You must let the boat reach an equilibrium before you have your navigator estimate the max. range, otherwise, his figures will be inaccurate.) Did you charge batteries on the way back? Could you have set the speed higher than you meant to?

In general, it is best to avoid using the battery as far as fuel is concerned. Charging uses up a significant amount.

I follow the same general procedure you do; that is, tabulating the fuel consumption at different speeds, and then computing what I will need as the patrol progresses. It always works for me. However, I, and most others here, play v1.5 of the game, with mods, so there may be oddities in v1.4, that I don't know about.
