1. Voltage balancing with balance resistors/passive method The simple and most cost-effective way to balance the voltages across the supercapacitors is to connect resistors of equal value across each supercapacitor. As the resistor is connected permanently across supercapacitors, the power dissipation in the resistors will be continuous.
The set supercapacitor voltage should be twice that of the threshold voltage. Each capacitor will charge to the gate threshold voltage. But this will be an expensive method of voltage balancing as the cost of these dedicated ICs is more.
For applications where the supercapacitor needs to be charged to more than 2.5V or 2.7V, engineers are forced to connect multiple supercapacitors in series as the standard supercapacitor voltage is rated to 2.7V and they are of lower cost.

Würth Elektronik technical article written by René Kalbitz explains some theoretical background of supercapacitor balancing methods and verify it is effectiveness in practical measurement and comparison.
This leads in voltage imbalance across supercapacitors since one supercapacitor voltage will have greater voltage than the other supercapacitor. As the temperature and age of supercapacitors increase, this voltage imbalance become worst and the voltage across one supercapacitor may increase to more than the rated voltage.
For this application, the supercapacitor must be charged to 4.5V, and during the backup, the supercapacitor voltage is boosted and regulated to 4.75V when the actual system voltage is absent.
