Submarine questions

When a submarine is running on the surface with both diesels on propulsion, does this mean he batteries are powering everything on board? Is there no other generator for lighting etc? How long would it take to charge up air and batteries at the same time? Would it be only one of the diesels connected to the dynamo or could both charge at the expense of propelling the vessel?

Also, if ballast is blown at a great depth would water need to be taken on on the way up to compensate for air in the ballast tanks expanding as the water pressure drops?
