Electro-thermal coupling model of supercapacitor for online application
Online temperature observation is very important for the health diagnosis and safe operation of the supercapacitor energy storage system. The paper presents an electro-thermal coupling model to estimate the temperature in supercapacitor. Firstly, an electro-thermal coupling model is built for the purpose of online temperature observation. Secondly, in order to improve the accuracy of the model for online application, a H infinite filter is designed for the model. The results of experiments show that electro-thermal coupling model achieves good accuracy. The absolute error of temperature is less than 1.4°G. Moreover, after adding the H infinity filter to the electro-thermal coupling model, the accuracy of the model is greatly improved, and the absolute error is less than 0.4°C. Furthermore, an online implementation strategy for this electro-thermal coupling model is discussed.
