battery recharge question:historic

brett25 · 02-07-10, 09:06 PM

I noticed in SH3 that I am able to recharge the battery without moving the sub, as long as the engines are running and im in recharge mode. Does anyone know if this is historically correct? Did the uboats have a gear that disabled the propeller shaft allowing the engine to stiull spin the shaft to recharge the batteries withput having to be in motion?

I belive when U boats are rechargeing they use one engine to spin one prop and the other to recharge.

so, i believe if the were stopped, they would have 1 engine rechagreing and running and the other stopped.

Task force is correct. they would also run extremely fuel efficient-like, by running 1 diesel through both electrics to run the boat. that was a solid 4 Kts.

ok thanks that makes sense. do you know of any good books covering the engineering and mechanics off the uboat?

Recharging batteries whilst stationary is not realistic...but simply a glitch in the game that has not been addressed thus far.

One book, a biography on Wolfgang Luth goes into detail about the IXD2. Clay Blairs' Books go into alot of detail, if you read both front to back, (done that 4 times here

)

@jibuna , do you know if this was because the crew typically did not do that, or is it because its not possible mechanically speaking.

@ryanglavin thanks for those suggestions
