Mathematical Models of Flash Charging Method for Supercapacitors

2022-10-29
● Recently, a lot of mobile equipment has installed “Electrical energy storage devices” that are available in various markets. It is preferable that all kinds of mobile equipment will be used in the condition of high efficiency.However, the idle time relating with moving to charging stations and recharging the devices is inevitable. To save time, supercapacitors, such as “Electrical Double Layer Capacitor” or “Lithium-Ion Capacitor” with huge capacitance, can be employed because of their excellent rapid charging abilities.
● In order to charge them, a power supply that can provide a supercapacitor with enough electricity is required. Although supercapacitors have such great benefit, it is very difficult to find the power supply whose cost or weight is satisfactory. With this in mind, a simple rapid charging system while using a supercapacitor is strongly advised. Flash Charging Method is a solution that enables charging supercapacitors rapidly.
● This paper presents Mathematical Models which can implement to calculate the charging time when Flash Charging Method is applied to charge supercapacitors, even though both a required “State of Chargeʢ SOCʣ ” and a required charging time are settled prior to the system design. Results of experiments to demonstrate the models are also presented.
