Therefore, DVA of all cells in the first and second temperature phase were performed to reveal the underlying aging mechanisms. DVA is a well-known tool for investigating aging mechanisms by separating anode and cathode contributions in full cells and shifts in the electrode balancing .
At first, conventional cell terminal voltage based ICA/DVA methods are transformed to SOC based ICA/DVA methods, which are insensitive to the changed battery resistance and polarization during battery aging processes.
The reliability and safety of battery operations necessitate an efficient battery management system (BMS) with accurate battery state of charge (SOC) and capacity estimation techniques. This paper investigates the incremental capacity analysis (ICA) and differential voltage analysis (DVA) methods for onboard battery SOC and capacity estimation.
While DVA is defined as the rate of change in voltage with a change in capacity (dV/dQ), ICA is defined as the rate of change in charge with a change in voltage (dQ/dV). From a literate explanation this can initially appear somewhat complex. .
Degradation pathways (loss of lithium inventory vs. loss of electrode capacities) become apparent in Differential Voltage Analysis (DVA). Figure 8 a shows the voltage profile of a fresh full-cell as recorded during a constant-current charge at C/25.
Accurate battery SOC and capacity estimation can contribute to reliable and safe battery utilization. In this paper, ICA/DVA methods have been developed for onboard implementation for battery SOC and capacity estimation. At first, the conventional cell terminal voltage based IC/DV curves were transferred to the SOC based IC/DV curves.
