In summary, the full discharge and full charge states of the hybrid battery pack depend on the NMC cell and LFP cell respectively. The capacity and SOC of the hybrid battery pack are calculated as shown in Eq. (10) and Eq. (11).
In the hybrid battery pack studied in this paper, the full charge of the LFP battery determines the full charge of the pack. However, because there are two different types of batteries in the pack, constant current and constant voltage charging is not possible. This means that the pack does not reach a true full charge state.
The two cells are pre-treated using 1/3C constant current charging and discharging before the individual cells are joined in series to create a battery pack. The initial SOC of the NMC and the LFP are 0 % and 10 %, respectively. The two cells control the empty and full states of the hybrid battery pack, respectively.
In the presence of voltage and current sensor errors, the estimation error can still be maintained at around 1 %, showing good robustness. On this basis, the capacity and SOC estimation of the hybrid battery pack also shows excellent results. Guan Wang: Conceptualization, Methodology, Software, Writing – original draft.
