Battery Degradation Platform and Model for Realistic Battery Use Cases

In this paper, the mathematical evaluation model, extended wear density function (WDF), that evaluates battery remaining life is proposed. Also, a data platform to be utilized for the extended WDF is proposed. The previous WDF doesn't consider three factors; operation temperature, current, and operating state-of-charge (SOC). To build more practical WDF, we proposed the extended WDF model and data platform for the extended WDF. The measurement value of operation temperature, current, and operating SOC are transformed into coefficients for the extended WDF. The proposed data platform stores the measured data with the information of batteries specifications. The extended WDF model is trained by the gathered data so that it estimates battery degradation with the new experimental data which has the same attributes as the training data. In the simulation, the proposed extended WDF and data structure in the proposed platform is verified.
