In this study, an online cell screening algorithm is proposed to estimate the maximum peak current considering the cell inconsistencies in battery packs for electric vehicles. Based on the equivalent circuit model, the maximum peak current is mathematically defined, and the inconsistency parameters affecting the maximum peak current are analyzed. T...

... time interval (∆t = 10 s) was determined considering that the instantaneous peak current generated during gradient climbing, rapid acceleration, and regenerative braking is generally shorter than 10 s [23,24]. The maximum peak current is estimated based on an equivalent circuit model (ECM) consisting of an OCV and a diffusion resistance (R s ) based on the voltage drop for 1 s, as shown in Figure 2 [25]. In plenty of literature, n-th order resistor−capacitor (RC) model was used to accurately simulate the polarization effects [10,24,26,27]. ...

Lithium-ion batteries exhibit a dynamic voltage behaviour depending nonlinearly on current and state of charge. The modelling of lithium-ion batteries is therefore complicated and model parametrisation is often time demanding. Grey-box models combine physical and data-driven modelling to benefit from their respective advantages. Neural ordinary dif...
