Well I know that diesel Engines recharge the electric batteries but how? I searched google but all they keep on saying is "They get recharged by diesel engine". Well how does it get charged? By transfering energy to the batteries by using the "force"? http://forums.ubi.com/images/smilies/35.gif

This may seems stupid to you but i'm looking for a more complex answer then just "recharged by diesel engines". Damn google.

much like a car or a truck.. i believe they used alternators to transfer energy from a diesel to battery.

Thought so, thanks for confirming my thoughts. Well they could have used bikes to rechare it also if they are surfaced lol http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

Yeah, the diesel engines have a generator attached to them which is essentially the same thing as the alternator in a car which sap power from the drive screw to recharge the batteries.

I suppose theoretically, the electric motors could be used as generators themselves but I don't know enough about U-Boats to be able to say for certain.

When you're charging use the camera to check the props on your sub. Only one prob is running, other diesel is charging.

I never noticed that before. Well spotted.

AFAIK, the electric motor doubled as a generator for charging the batteries. It was coupled to the diesels via a 'clutch-plate'.

SO on the surface the clutch was engaged, and charging mode set. Underwater the clutch was disengaged and set for electric motor mode.

Vaguely remember this from somewhere.. http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif

Ah, that would be known as the "Gilligan" generator.

Hmm odd. Where are all these ships going and coming from http://forums.ubi.com/images/smilies/blink.gif Good enough hunting place at sector AN82. Well they go inbetween the 2 islands but I tried seeing where they go or leave so I could hunt some down. Well its more down south then I thought and I would have gone furter in with my U-1 IIA but my new VIIB was waiting for me. Hell of a storm cut me back also so I couldn't see where they were at. Well I think the VIIB is now to tall to go into sector AN86 so if anybody wants could you see if theres a hidden dock there? http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif

For those that cant think of the top of their heads. (map below)

One other point regarding charging the batteries, the diesels only generate so much "power" if the AI is right, and you want full or flank spped, the disels should not be putting much juice back into the batteries. If the AI is correct you need to go slow to recharge the batteries. I usually use slow or 1/3 out of habit, but I really don't know if it's necessary in this game.

The game as in real u-boats takes one whole engine to recharge the batteries.

You will note that ahead flank is slower when recharging for just that reason.

The engine linked to recharge is disconected from its prop. This means that you don't need to move to recharge the engine. It also means that the recharge rate is the same no matter what speed setting you use.

And yes, in german U-boats the e-motor doubles as the generator.

US boats were different, they had deisel electrics. That is the engines are attached to generators only and not the props. When running on deisels, they just power the motors directly from the generators.

Here's a tricky question:

While recharging the batteries, was the non-operating shaft set at neutral or was it locked?

In real life a locked shaft and screw (propeller) creates a lot of drag and reduces the hydrodynamic capabilities of a sea-going vessel. Was this modeled in the game?

Maybe it worked like this..
2x diesel engines = 2 electric motors = 2 chargers = 2 banks of batteries (with the neccessary cross-over links - those monstrous railway junction levers)

When running on Diesel, I've noticed vessel "looses" speed ( 1-3 knots mostly) , therefore either to a less engine or to hydrodynamics it seems that it is modelled.
