Ultracapacitor Charge Balancing

Posted on April 11, 2013April 13, 2013 The Engineer

I have finally  got round to designing the balancing circuitry for my ultracapacitor banks, which have a total voltage of 15v when fully charged. The 2600F capacitors have a max working voltage of 2.5v each, so to ensure reliable operation, balancing is required to make sure that each capacitor is

SEPIC Regulator Test Rig

Posted on December 9, 2012December 9, 2012 The Engineer

Here’s the regulator hooked up with test clips, on the right is the supply from the ultracapacitor bank, while on the left is the output, feeding a 2.3A brushless fan as a test load. These regulators do get warm, even with no load, with a 2.3A load on the output,

Ultracapacitor Voltage Regulation

Posted on July 29, 2012 The Engineer

As an ultracapacitor has a pretty linear discharge curve, some electronics are required to make them behave more like batteries, such as as SEPIC converter. On the right is a MuRata Power Solutions UQQ-12/8-Q12P-C switching regulator, which will accept a 9-36v input source & output a constant 12v at 8A

2600 Farad Ultra Capacitors

Posted on July 22, 2012 The Engineer

Just a quickie to note down the current progress of another project – Ultracapacitors. Pictured right is a bank of 6 2.5v 2600F Maxwell Boostcaps, for a total of 15v at 433.333F. A total energy storage of  48.7kJ. Coming soon will be the inclusion of charge balancing, using Zener diodes &
