Nonlinear Structural Model of the Battery

摘要

A nonlinear structural model of the battery that can be used for modeling the operation of alkaline,acid, and lithium-ionic batteries is constructed. This model retains all the advantages of traditionalstructural models: namely, it contains as many parameters as can be determined from experimentalstudies for the battery as a whole. This model, as well as all structural models, is graphic andunderstandable from both electrochemical and electrotechnical points of view. However, the proposednonlinear structural model can be used for modeling the operation of the battery at high currents thatare usually found in various modes of their operation. This is the main difference between the givenmodel and traditional structural models which are used only in the theory of an impedance, that is,during the use of small alternating currents.
