Batteries

I found:

Picture 1 shows situation when a submarine is surfaced. DC generators/electric machines (EM/G) are powered by diesel engines (DE). One part of produced electric power from the DC generators/electric machines is used for propulsion of the submarine propellers (P) and the rest of produced DC electric power is used for battery (B) charging. In this situation the diesel engines are full loaded. When the submarine's speed is faster the time of the battery charging is longer, because fast speed needs more electric power. Opposite, when the submarine's speed is slower the time for the battery charging is shorter. In that case, slower speed needs a smaller part of the electric power and the bigger part of the electric power remains for the battery charging.

This means on the surface at low speed?
