Pseudo open-circuit voltage (pOCV) curves of the anode, the cathode and the full cell are shown in Fig. 7c, respectively. Although a very low current of C/50 was applied, the charging and discharging curves do not overlap (see zoom-in in Fig. 7d). Based on Ohm’s law with the ...
the controllers20read the current integrated value ICV from the memories24, and acquire the variation capacity VC (also referred to as the variation battery capacity VC) of LFP cell based on the current integrated value ICV. Specifically, when the charging and discharging...
(ICA) for electric vehicles. Using cycling data from lithium-ion battery cells at various temperatures, we extracted the charging cycles and calculated the DVA and ICA curves, which are then filtered with an IIR-filter to reduce noise. Multiple features (i.e., peaks or valleys...

- Protection of the cell against under voltage by switching off the load in good time. - Protection of the cell against over voltage by reducing the charging current or switching off the charging process. - Shutting down the system in the event of excess temperature. -...
The charge–discharge machine used in the experiment had the following parameters: (Neware, CT-4002-5V100A-NA, 2 channels, voltage/current accuracy ± 0.1% FS, power accuracy ± 0.2% FS). All test batteries were discharged to the corresponding lower limit cut-off voltage using a 1/3C ...
4.1.2. Equilibrium Potential Curve A second important electrochemical parameter that characterizes the electrochemical model is the equilibrium potential curve of the cathode (OCV, open-circuit voltage). The curve should represent voltage as a function of State of Charge (SoC), covering a potential ...
