Battery charging is spot on!!! - Page 3

I had just finninshed one attack wave on a convoy off of Japan. It is late 42 and I am in command of a Tambor class boat.

Following the attack and run away, I am parelleling the convoy's last known course. At first I was going at full speed. I checked my battery level and noticed it was charging really slowly if at all, so I dropped to standard (still about 12 knots), and saw a small jump in the charge rate, then out of curiostiy I dropped it down to 2/3 (or the step below standard) and saw a bigger jump. Then it dawned on me.

The devs did their homework, just like they did with SH3.

With the German boats for battery charging one engine was dissconected from the prop shaft, and left connected to only the generator, leaving one prop stopped or "windmilling". This was simulated in Sh3 quite well.

With SH4 the same is done with the 2 engined/ direct drive S-boat. When charging one prop is stopped.

Now the newer fleet boats had four engines, none directly connected to the drive shafts, instead they were connected to a generator which in turn was connected to either the batteries, or directly to the drive motors. When traveling at slow and charging the boat would be proppelled by one or two engines, while the other two or three would charge the batteries. At standard it was two engines connected to the motors, and two to the generators. Then at full three driving one charging. At full all four would be driving, with a little bled off for charging, and at flank, no charging.

In SH4 this is simulated quite well. You will also notice there is no increase in speed when the battery indicates fully charged, like you get with the older or german boats. Also, while charging both propellers are turning.

I have to say, I am impressed.
