S Class not recharging batteries

[Peto]

If this subject is already covered elsewhere, I apologize and would appreciate being pointed in the right direction.

After installing 1.3 it seems my S Class boats no longer charge their batteries--or at least it takes a Very...Long...Time. Not workable when I like to dive for the day because it takes longer than 1 night to recharge. Has anyone else run into this or is there a fix?

Thank You All for the Great Work You Do!!!!!

yup i have this too

annoying...

My periscopes dont animate either, pain...

Takes hell of a long time to get a charge... very slow...

Had a quick look at sim file...

She has her diesel eng_power lower than her electrics, checked a few other boats, they are all fine, suggest increase diesel eng_power, maybe that will fix it...

Will test...

[Peto]

Thanks Jace! Good thread going over in the general forum too!

Salute!!!

I increased diesel_eng power to 4200 (still less than a porpoise) it was set at 1200 while electrics were >2000..

Didn't change much, still takes too long to charge up..

[Peto]

Thanks for the update Jace! I'm going to try to track down the problem too although you're more experienced with this program than I am. If I discover anything I'll let you know right away.

Cheers!

The problem appears to be in all boats. Someone complained in patch 2 that the batteries were unrealistice. I think the Devs went too far in the other direction. I have also tried the solutions mentioned above, but to little avail. Example: Battery down to 50% off Honshu - halfway between Midway and Pearl on return vovage running at flank speed battery finally recharges. Am I to believe that to be realistic? Help needed Please.

[Bando]

It seems to me that running at flank speed is not going to charge the batteries any time soon. With 4 diesels aboard running flank speed, all diesels will be used for propulsion rather than recharging. Normally, the less diesel engines you need for propulsion, the more diesels are available for recharging, hence at slow speed, recharging should be quicker.

Having said that, I think Bear is right. All the boats seem to have this in more or less state, the S class being the worst.
To Jace, the change of Horse power is not going to speed up the recharge proces. I'm not a wizzard, or expert, I tried to set it very high, no change.
Therefore, HP is not the solution. I did not figure out what is, still an ongoing process.

I was going to post a subject on battery recharge till I read this thread. It seems most subs take a long time to recharge, I was almost out of batteries when I got a chance to surface, It took 2 days to recharge.
It seems like it wasn't recharging till I switched between speeds, flank to 1/3 back to flank, an then it started recharging, but vary slowly.
I searched for anything that might refer me to a recharge time but with no luck.
Maybe the dev added a new line that the tweak files don't have?

[Mechman]

If somebody figures out how to fix this, maybe it can be rolled together with the battery life mod.

[THE_MASK]

Simple fix...when submerged travel at 1 knot during the day...works a treat...

[pythos]

The 1200 diesle power for the S boats might be because the S boats had only 2 600 horse power engines. The electric motors were 1175 for the S18 class, and 750 hp for the S-42. (remeber to multiply these figures by two for the full power of the electrics. So indeed the electric motors were more powerful than the surface propulsion.

The porpoise class had 4x1,300hp diesles, and 4x521 hp motors.

The batteries on subs drained quite fast at high loads, and charged quite slow. It did take nearly an entire night's running on the surface at 2/3 speed to charge the batteries. This is why subs were more diving boats than true submarines.

Compared to the German boats, American boats were not all that great, until the advent of the Gato, and Balao class subs. The Uboats could charge batteries quicker, but also had smaller capacity compared to the american ocean cruisers (which aside from the Sboats all american subs of WWII were.).

The charging times may in fact be accurate.

[Mechman]

Still, with the lower charge the s-boat batteries hold, a 24 to 36 hour charge time is a bit much.

[Peto]

Agreed Mechman. It takes me more than 24 hours to recharge batteries. Much more if they're below half.

While your points are accurate pythos--and well researched :yep: --this problem is a game bug. It makes the S Class pretty much unusable for a Career boat in my opinion.

Cheers All! I'll buy a drink to anyone who figures out this little annoyance. But I'll want to see some ID to make sure you're of legal age LOL.

I found if I run at slow speed my batteries recharge faster, if I run at flank batteries charge at ~1% per hour.

See post 7

[Bear]

I will try that, anything other than diving down and sitting still all day to preserve battery life. In patch 2 when they did run down it appeared to me the harder you ran the faster they recharged, but what you say about the engines makes sense. Thanks.

[Ducimus]

Try lowering the Emotor Power (by half if neccessary), and offset any speed loss by increasing the top speed porportionate to the speed loss.

[Mechman]

What? That just means increasing speed after you cut speed, and doesn't help any.

[Peto]

Actually--I see what Ducimus is getting at. True: you're adding speed after cutting speed but you're also cutting the power (hence power requirements) of the electrics.

Has anyone tried this yet? I'm sporting around in the Perch right now and everyone is counting on me to keep the Japanese out of Darwin.

Cheers!

Has anyone had any luck fixing the problem with the S-Class?

[Bando]

I've played for over a week with the S class now, and it doesn't bother me that much. Meaning the reload time. I think of it as being actual and pay extra attention to draining the batteries.
It's a feature to me really.....:up:

U-boats could stay under a LOT longer than the American boats could though. U-boat electric engines were probably more efficient than the American counterparts and if they weren't better necessarily, they didn't have to push a boat as large as the American Boat through the water. Even though in terms of batteries, size does matter, its worth pointing out that AFA's batteries were very high quality.

The American boats were far supperior to the U-boat when on the surface in terms of general cruising. Except for the S-boats a VIIC would leave one of them standing.

Still I do like the American subs, they had radar technology which was above and beyond the german equivalents.

How do you figure?


VIIc: 80/4

IXc: 64/4

Gato: 100 nm at 3 knots (185 km at 5.6 km/h) (maximum) submerged
http://en.wikipedia.org/wiki/Gato_class_submarine

Looks about the same to me.

Most sources give the Gato 48 hours submerged endurance.

[Ducimus]

Endurance is all about how fast your going. At 2 kts a gato had a 48 hour endurance from all ive heard. Uboats weren't particuarlly superior at anything except deeper diving, and probably submerged turning radius in the type 7 varients.

If i remember correctly In terms of recharging batteries, The Us fleet boats had it over the uboats. Uboats and two direct drive engines as i understand. When on the surface a clutch was engaged the purpulsion was switched where the engines directly drived the props, with the Emotors unused. If they wanted to recharge, they had to put one engine "off the line".

In a fleet boat, the emotors are what always drive the props, what changes is the power source. Batteries, or four diesal engines albiet smaller then the two engines the germans used. But since its an indirect drive, the battery recharge and needs for surface propulsion had greater flexbilty, and its surface propulsion relativly unphased.


Now as to that bloody S boat, ive tried all sorts of funky stuff, about the only thing i ever manged to do, was reduce the battery drain, thats about it.
