In this paper, a data pieces-based battery parameter identification (DPPI) method is proposed. The target of this method is to identify comprehensive battery parameters including battery capacity, OCV-Ah relationship, and impedance-Ah relationship simultaneously only based on battery operation data, e.g. voltage, current and temperature.
In order to perform battery parameter identification, long driving cycles have to be cut into many small “unit data pieces”, as shown in Fig. 1 (a), the red grids and green grids cut each long driving cycle into 22 unit data pieces by two layers. Each “unit data piece” is the basic unit for battery parameter identification.
6. Conclusions This paper has proposed a data pieces based battery parameter identification method (DPPI) to identify battery OCV-SoC relationship, capacity, and impedance based on battery operation data.
These models facilitate enhanced performance analysis and optimization in battery management applications. The state of power (SOP) of lithium-ion batteries is defined as the peak power absorbed or released by the battery over a specific time scale. This parameter has gained increasing importance as a key indicator of the battery’s state.
The Bayesian algorithm is often used for parameter identification in electrochemical models. In , a Bayesian parameter identification framework for lithium-ion batteries was presented, wherein 15 parameters were identified within a pseudo-two-dimensional model.
The current parameter identification method mainly uses the collected voltage, current and other parameters; combined with the mechanism and algorithm used to identify the parameters of the established battery model, the error and robustness need to be further improved.
