Recharge batteries

Bathrone · 05-13-13, 03:35 AM

Is the rate of recharging batteries dependant on sub speed setting (e.g flank)?

How to maximise recharge time?

Hi Bathrone
There are orders to stop charging the batteries and I have noticed that my maximum speed drops a few knots while the batteries are being charged which is not good if you need that extra bit of speed to reach an intercept point.
Best wishes Peter

Ah yes quite true but not what I was asking

Ofcourse the speed drops when charging cos one diesel goes to the generator not the propellor

What Id like to know is if higher speeds charge the batteries faster or if I just go dead slow theyll charge at the same rate

I think so. Higher RPM should charge batteries faster. Didn't test it really in game, but it seems to me...

It shouldn't matter. the diesel charging the battery always runs at full speed, just for that purpose. In SH3 you could look at the guages and see one diesel running at slow speed (or whatevery you set it for) while the one doing the charging raced as fast as it could go. It should be the same in SH5.

This is how the engines code of SH5 is working. When recharging batts the starboard engine is set to ahead flank (or is it the port engine?) while it's disconnected from the shaft.

I've thought about adding a new command to the game - extreme battery recharging. This would allow both engines to recharge batts at the expense of no propulsion

Could be quite handy sometimes.

Also thought about adding another new command to game - one that would allow the electric engines to be coupled to the diesel engines when at ahead flank for a little more knots.

Cool ideas, but were them realistically feasible in RL?

I know the coupling of electric engines to diesel engines was used for emergency situations or to gain a few knots of top speed. As far as the extreme battery recharging goes I have no idea. One would think that they could do this and probably did when they needed batteries recharged quickly. If someone can find documentation of this being used that would be great. It wouldn't hurt to add it to the game - user would have option whether they wanted to use it or not.

Hey bud

Do you know any possible way to mod a reductio of recharge times from 12 hours to sh3´s 4-6h?

Bathrone · 05-18-13, 05:39 AM

The game with the usual suspects of mods doesnt portray this. While recharging batteries both engines display what the speed is set to not one of them on ahead flank and the other set to what the speed is set too

It's not correct..
As you can see in the picture - battery level is 88, so batteries are recharging.. starboard engine's tachometer shows high rpm i.e. ahead flank, port engine's tachometer shows low rpm i.e. ahead one third i.e. ordered speed..

I agree, it should work that way. The only question is whether they designed it that way. They should have, but did they?

So I had a look at the original reports from the captured U-570 and found some surprising facts:

Quote:

The drive is direct connected diesel. The chief engineer stated that switching arrangements are provided so that one engine can drive its own propeller direct, and, with its motor operating as a generator, drive the other propeller by electric drive.
-Section II - C - 1 - General

http://www.uboatarchive.net/U-570ONIReport.htm

This would imply that while recharging both propellers would still be turning. If the starboard engine was recharging the batteries that propeller would be turned by the starboard motor, from electricity supplied by the port engine. Would this mean the port engine would have to run a little faster than normal to drive both propellers?

The above is from the American report, and doesn't say whether both engines can charge the batteries.

I couldn't find anything in the British Report that said anything about whether both engines could recharge the batteries or not.

Thanks for that Volodya, nice to see it can work. So I unset all my mods and deleted my SH5 documents folder and tried it again. Now its working, must have been some sort of mod induced soup.

What UI mod is being used in this screens hot?
