How does the process of recharging of the batteries? and why the submarine it is on surface during charging?

[HW3]

Batteries are recharged by electric generators powered by one of the diesel engines, so the sub must be on the surface, or using a snorkel, to supply the air needed to run the diesel engine.

[Markey33]

But when the submarine is submerged, and not the electric motor that works?

[HW3]

The batteries are used to power the electric generators to provide propulsion and power the submarine.

[Markey33]

Yes I understand, but what I didn't understand and that when they are using the Snorckel the submarine is submerged and as it is loading the batteries if the diesel engine is stopped

[HW3]

When the snorkel is used they are running the Diesel engines drawing in air through the snorkel.
