Hierachical battery Model with variable internal resistance

This circuit models a LiFePO4 cell voltage.

Based off of the model described in:
Liao Chenglin; Li Huiju; Wang Lifang, "A dynamic equivalent circuit model of LiFePO4 cathode material for lithium ion batteries on hybrid electric vehicles," Vehicle Power and Propulsion Conference, 2009. VPPC '09. IEEE , vol., no., pp.1662,1665, 7-10 Sept. 2009
doi: 10.1109/VPPC.2009.5289681

initial SOC [no units] (0.0 - 1.0)
initial charge capacity [Amphour] (> 0.0)

See this test circuit, which implements a hierarchical version of this model:
