文摘
- •
A combination of data-based models for modeling battery power dynamics is proposed.
- •
The Takacs hysteresis model is used to describe major and minor hysteresis loops.
- •
The state of charge can be estimated within the proposed battery model.
- •
A recursive Instrumental-Variable method is applied for parameter identification.
- •
The model aims to be applied for battery systems in an electric grid.
