To deliver the required energy and/or power, supercapacitors are usually connected in parallel. Connecting supercapacitors in parallel increases capacitance and decreases the equivalent series resistance (ESR). This connection is suitable when higher energy and/or power are required.
When connecting supercapacitors in series, it is important to ensure that there is equal distribution of cell voltage. In applications that demand higher energy and/or power, more than one supercapacitor are required. To deliver the required energy and/or power, supercapacitors are usually connected in parallel.
Individual supercapacitors are limited to 2.5 V (P Series reaches 5 V using two supercapacitors in series). As many applications require higher voltages, supercapacitors can be configured in series to increase the working voltage.
If a series resistor is used, ensure that the voltage outputs of the supercapacitor are connected directly to the application and not through the resistor, otherwise the low impedance of the supercapacitor will be nullified. Many battery systems exhibit decreased lifetime when exposed to high current discharge pulses.
In addition, supercapacitors that are connected in series require a balancing circuit to ensure that there is a voltage balance. Consider a system in which two supercapacitors with same part number are connected in series. Despite the components being similar, their insulated resistance and capacitance can be different.
Many manufacturers design customized supercapacitor modules to meet the requirements of a specific application. Supercapacitors have low cell voltages, typically 0.9to 3.3V, and they are commonly connected in parallel or series to form modules.
