Das et al. proposed a real-time regulation method for the coordinated charging and discharging of EVs based on a dynamic planning method that takes into account the cost of EVs and the operational needs of the grid, effectively reducing the charging cost of EV users and alleviating the pressure of the grid .
So, here we are using a supercapacitor that charges and discharges in less time. The design of electric vehicle will remain the same, but we are adding a super capacitor bank inside the EV for charging the battery. The super capacitor is supplied from through the off-board charger with the plug-in configuration.
We developed an innovative change in the existing infrastructure for rapid charging in EV based on super capacitors.
Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
The charging and discharging process of this system mainly consists of two parts: the consumption of electrolytes when the voltage is higher than the open-circuit voltage and the migration of lithium ions when the voltage is lower than the open-circuit voltage.
However, the charging behavior of EV users is random and unpredictable , which will increase the control difficulty of the grid , reduce the voltage quality and the stability of the power system when large-scale EVs are connected to the grid [10, 11].
