What Is EDLC?
EDLC stands for electrochemical double-layer capacitor. Energy is stored predominantly through charge separation at the electrode–electrolyte interface.
What Is ESR in a Supercapacitor?
Equivalent series resistance is the effective resistance in the capacitor current path. It determines an instantaneous voltage drop and contributes to heat under load.
How to Calculate Supercapacitor Energy
The ideal energy in a capacitor is E = ½CV². Usable energy depends on the minimum voltage your load or converter can accept.
How to Design a Supercapacitor Module
A module is more than a number of cells connected together. Balancing, protection, terminals, enclosure and thermal management must be designed as a system.
How to Connect Supercapacitors in Series
Connecting cells in series increases the bank voltage capability, but reduces equivalent capacitance. Individual cell voltage must still remain within its limit.
How to Connect Supercapacitors in Parallel
Connecting matched cells in parallel increases equivalent capacitance. The allowable bank voltage does not increase.
Supercapacitor Balancing: Passive vs Active
Balancing limits voltage differences between series-connected cells. The right method depends on leakage, standby power, charging behavior and complexity.
