I have read a topic about research of the capacitor recharging http://oldforums.eveonline.com/?a=topic&threadID=116993
As I can see, no final formula of capacitor recharging have been discovered. Well, here it is
Capacitor energy calculation is based on "ticks". In above formula Cmax is capasitor capacity, C0 is capacitor energy in t0 time, C1 is capacitor energy in t1 time. Tau is recharge rate, divided by 5
I have made graph of capacitor energy vs. time for hypothetical ship with capacitor capacity of 100 and recharge rate 100 seconds. In addition, one more graph or instant recharge rate to average recharge rate vs. capacitor energy.
You can mange different capacitor capacity and recharge time in excel table.
Conclusions:
1) Capacitor recharging determines by capacity and recharge time only.
2) 90% of capacitor energy can be gained in 60% of recharge time.
3) Peak capacitor recharge rate is in 25% of its capacity.

I think so. It's seems that shield and capacitor restoration has same algorithm.

You may have missed it but it was posted on second page. And it gives correct results but with your formula peak recharge is shifted (Actual peak is at 29.5%).
I have grabbed video to find peak of capacitor recharging. UI updating once per second and it is not enough to catch the peak. Speed of recharge is same at 25% and at 30%. Please tell me, how can I try to find peek moment more precisely?
P.S.: Formula from previous topic use trigonometric. Such functions is also "hard" to compute.

Big capacitor, slow recharge time.
I'd recommend something like Dominix full of capacitor batteries and shield power relays 
Start/stop warps until cap depleted, wait for it to recharge.
Might take a damned long while, but gives awesomely precise readings.
Thanks, I'll try it tomorrow.

I have made some tests to find peak of capacitor recharging. Raven with 5 Shield Power Relays and 5 Large Peroxide Capacitor Power Cells has capacitor capacity of 10695 units and capacitor recharge time 4142.8 seconds (with my skills). Here are the results.
Some comments. I've write down capacitor's charge readouts for 270 seconds (from capacitor charge 17% to 33%). For each tick, we can easy find a capacitor's charge increment. Unfortunately, due to readouts rounding this is not enough to find peak. Nevertheless, we can easily find a moving average (I used 120 points) to isolate the peak. Finally, peak recharge rate is located on 25.2% of capacitor's charge. All of this is in excel file.
P.S.: Mathematically, peak should be on 25% exactly. This can be found from formula (get the second derivative and find extremum).

Gripen, can you give some comments to my test. I'm i right and peak is at 25% ?
