Two equivalent circuit models of lithium-ion capacitor are established. The assumptions and preconditions of the two-branch model are deeply analyzed. A new parameter identification method is proposed for the two-branch model. Experimentation and simulation are compared under more complete working condition.
A method for SOC estimation of lithium-ion capacitor is proposed. The parameters of equivalent circuit model is obtained by using variable forgetting factor recursive least square. Adaptive square root cubature Kalman filter is adopted to enhance estimation accuracy and stability.
For MEMS technology based capacitors, 3 main parameters of concern are as follows: high Q factor, high tuning ratio, and low pull-in voltage. These parameters in turn depend on the materials to be used for the metal plates and dielectric layer.
The precise state of charge estimation is essential to utilize lithium-ion capacitor efficiently. In this paper, the electrical characteristics of lithium-ion capacitor have been studied and the corresponding equivalent circuit model is established.
This model is smooth, continuous and accurate throughout all operating regions. • Separate effective channel length and width are used for capacitance models.
