Recharge time vs. Surface Speed?

[Fade Anadarkus]

Does your batteries recharge at different rates based on the different surface speeds? If so which is the most efficient at charging batteries?

Thanks for the help

[CapnBlood]

The two slower speeds on your dial charge faster b/c only 1 diesel is needed for propulsion while the other works on charging the batteries.

As CapnBlood said

If you're really on a tight fuel constraint, charge at night while stopped, this charges the fastest obviously

If i can i always charge at night so saving fuel and always tend to have a load left when each patrol is over

Really?

I havent noticed any change in the 'recharge rate' regardless of speed set. It takes about the same amount of time wether at ahead flank or sitting still.

It appears that at least game engine wise that recharging batteries siphons off a set amout of fuel over a period of time. The longer the charge the longer the period of time. The amount of fuel consumed appears to be a constant.

Yes you can recharge while sitting on the surface at all stop. But it does continue to consume fuel.

It might be interesting to do some controlled experiments to 'prove' my impressions.

Best add the main mods i use have always been TM/TMo and ROW/PE3/PE4

Think that CCIP did the battery mod for Trigger Maru to make things more intense

I've always used the above mods and assorted others, I got that used to using them i sometimes forget that others might not be using them

If i get chance later i'll time flank speed charge time and all stop charge time

Maybe just with TM/TMo and CCIP's batt mod

Ok i made time for a fast time compression test lol

Using TMo PE4 and assorted visual skins

All stop charge from drained batts to fully charged was 10hrs 21mins

Flank ahead charge from drained batts to fully charged was 34hrs 18mins

Quite a difference lol

I guess Stock has no modded charge states/times ? (never really played stock you see so wouldn't know)

And for sure you use loadsa diesel up charging for longer (again maybe just the devious CCIP and Ducimus tweaks in TMo)

Just curious, based on your test, did you watch the fuel consumption during the trials? I have been trying to get a grip on my fuel consumption so that I can better plan my patrols. I beleive -PV-, in a previous post, recommended that I recharge at 1/3. I usually recharge at the halt when possible, because I believe it is reducing my fuel consumption during the process (no numbers to back that up however).

Generally speaking best range at speed appears to be around 9.5 knots. You can verify this easly by changing speeds, waiting a few minutes for things to 'settle down' and pushing the 'range at current speed' button. Note that I have checked this with and without RFB installed and the results were roughly the same. TMO may be different.

At 10 knots the range goes down a bit, at 12 it goes down alot, at flank it is almost 1/3 of the range at 9 knots. Supprissingly at 8 knots the range is also less :hmm:

Now I havent tested this with batteries charging and without. Havent really worried about it to be honest. Unfortunatly there is no fuel flow gauge available so were relegated to a lot of guess work.

I may do a little testing tonight to try and verify things a bit more.


By the way where the hell are my manners?

Wow! Charge at night while stopped. Does nobody care about playing realistically? That is playing like the vast majority of too-old captains at the beginning of the war whose lack of aggression and complacence required most of them to be removed from commmand and the age ceiling to be lowered for those considered for future commands.

Battery life is a matter planning, of staying on the surface every possible second and submerging only if your life depends on it. In your sugar boat you have the nimblest sub in the fleet and you can pull the plug in a hurry. Stay on the surface until you see a plane. Keep those batteries ready for use and don't let them get below half charge.

With RFB, run ahead standard and you can search maximum ocean surface area while still keeping batteries charged up. Plan ahead and there's no excuse to run around with flat batteries.

Well I do bob around full stop when I get those 'patrol' missions assigned out away from the shipping lanes. No use in burning fuel when Im pretty sure there is nothing else out there.

I do dive when aircraft are likely to spot me but spend the majority of time on the surface.

While were at it... why can I dive in roughly the same time from a complete stop vs ahead at flank... Hmmm ??? :rotfl:

By the way RR I know that RFB is supposed to offer best range at ahead standard, but check your range at current speed at ahead xxx er standard, then drop your speed to 9.5 knots and check again

Ouch....

Nothing like getting your A$$ chewed by an admiral on your day off. Should have just went in to the office today.

No more casual bobbing for this guy. All Ahead 1/3, next stop, Tokyo.

..."casual bobbing"...I don't think came out right....

Ahead full and ahead standard are different. You lost me there. Is ahead standard faster than 9.5 knots?

In my sugar boat, ahead emergency is onlly half a knot faster than 9½ knots. Settin' the world on fire!

woops bit of a typo... meant ahead standard Ill go fix it

Sugar boats seem to be the exception to this 'rule of thumb'. But they have a hell of a range anyhow.

But in the other boats ahead std is about 10 to 11 knots, drop it to 9.5 knots and the range increases by a good bit. Dunno why, just a sweet spot in the games programming.

Don't sweat it too much. We're nice folks here.

But we all take turns at having our 'moments'.

I used to like it when Trigger Maru had ahead 1/3 set for 9 knots, best fuel economy. Then somebody talked Ducimus out of what was a masterful scheme. RFB is OK with ahead standard being close to best fuel economy, but when I get out of the S boat it looks like I'll discover it needs tweaking.

So Steve, you think 9 1/2 knots is a more economical speed than 9? I sure hope you're right. An extra half knot would come in handy sometimes.
