Supercapacitor charging methods from 0 V.
<< < (3/7) > >>

The Maxwell super cap modules that I have (58F/15V, BPAK0058 E015) have 6 caps in series.  They sell two versions... the low standby discharge ones use op-amps and interconnecting cables between modules to do balancing.  The standard ones just have resistors (270 ohm?) in parallel with each cap in the modules.  They came out of wind turbines and had 20 modules (300V) in series.  Check their app notes for balancing info.

I forgot to mention that my bank has active balancing circuits made by Maxwell.

I have a 12V 1500W power supply and if I can add some type of resistance in series I should be able to limit the current to the max rated power output of my power supply.

Problem is finding a resistance that will handle the load and not glow red hot and melt!
drummerdimitri:
So I tried using my 500W 0.2 Ohm resistor bank and although it worked, the charging time is still quite slow since the current draw decreases rapidly as the charge of the capacitors goes up.

I am now convinced I need a CC power source that switches to a CV algorithm midway to get the fast charging I need.

Why not CC all the way?

You want to have supply which switches to CV *only* when nominal voltage reached - basically at the very end of the capacitor charging.
