This takes the pressure off the battery, preventing large current surges and deep discharges. However, the battery remains the primary source of power for continuous operation. Once the transient passes, the battery can replenish the supercapacitor's charge and continue powering the system.
This approach addresses the common limitation of batteries in handling instantaneous power surges, which is a significant issue in many energy storage applications. The development of a MATLAB Simulink model to illustrate the role of supercapacitors in reducing battery stress is demonstrated.
Their recyclability and extended lifespan compared to batteries make them environmentally advantageous.

Overcoming this limitation has been a significant challenge for researchers and engineers working on supercapacitor technology.
Supercapacitors could charge from a very small current. When charging, it stores chargers inside the layers of the supercapacitor. Due to high charge density, the voltage of the supercapacitor keeps increasing until it reaches the maximum rated voltage. Beyond the rated voltage, the supercapacitor would blast.
