The aging mode of the battery is quantified by the capacity ratio of electrodes and the SOC bias of the positive electrode. To better understand the variation of internal parameters with battery aging, the simplified electrochemical model is used to identify the parameters in Ref. .
Three aging modes of battery are quantified by the established OCV model. The semi-empirical models are proposed for three aging modes. The model of aging modes on ohmic/polarization resistance is established. Remaining useful life and SOH are predicted by proposed models and particle filter.
To identify the aging mechanism of the battery by using the OCV curve of electrodes, it is necessary to establish the correlation model between the aging and the OCV curves. Besides, considering that the SOC i of the electrode can not be measured directly, it is necessary to map the SOC of the whole battery to the electrode SOC i.
In the beginning, the loss of delithiated material in the negative electrode only has a weak effect on the battery capacity, because the negative electrode has excessive active substances, and the OCV curve of the negative electrode remains unchanged at the low SOC stage.
The indirect method is based on voltage, current, and temperature, combined with incremental capacity analysis (ICA), differential thermal voltammetry (DTV) and other means to evaluate cell aging. The cyclic aging behavior of lithium-ion batteries at room temperature is investigated by ICA and differential voltage analysis (DVA) in Ref. .
The results show that the loss of active materials accounts for at least 83% and 81% of the total capacity loss under 10C and 5C current, respectively. Ref. proposes a method to estimate the battery SOH based on the optimal partial charge voltage profiles.

I have the MPPT absorption voltage = 28.4V and fixed absorption period of 15min.

The setup will always be active day and night. The batteries may or may not become full during that day depending on light and energy usage. I''m a little confused on float, keeping it the same as the absorption makes sense to me. For example the absorption at 20V will get the pack to 20V, then a float of 20V would keep it fully charged.
