  ,, comprising eight to-be-calculated parameters, A11′, A12′, A13′, A21′, A22′, A23′ A31′ and A32′, representing a relation of converting Pn into Qn in the ith winding layer,
i represents the number of winding layers; and
Pn and Qn are acquired according to the photographed picture of each of the winding layers of the reference battery, and Pn and Qn are imported into the relation PnTFi′Qn=0 to calculate the to-be-calculated parameters in FC of each of the winding layers.
