The paper presents a modelling approach which, starting from experimental measurements, allows automatically deriving a lithium-ion battery electrical model. This procedure is applied to a 47.7 kW lithium-manganese oxide battery unit in order to infer a third-order Thevenin equivalent electrical model of the unit itself. By means of a matrix representation of specific experimental measurements, it is possible to automatically derive the equivalent electrical parameters which represent the battery behaviour in any operation condition without having an in depth knowledge of the battery electrochemistry.

Abstract
The paper presents a modelling approach which, starting from experimental measurements, allows automatically deriving a lithium-ion battery electrical model. This procedure is applied to a 47.7 kW lithium-manganese oxide battery unit in order to infer a third-order Thevenin equivalent electrical model of the unit itself. By means of a matrix representation of specific experimental measurements, it is possible to automatically derive the equivalent electrical parameters which represent the battery behaviour in any operation condition without having an in depth knowledge of the battery electrochemistry.
