Abstract：Battery’s dynamics need to be modeled accurately for effective battery management. A nengineering modeling method for power battery dynamics is proposed. This method is based on the internal physical-chemical mechanism of the battery dynamics and the nonlinearity of battery’s constant current characteristics. The core of the proposed method includes a model consisting of a constant current curve and an equivalent circuit model, and a set of procedures, i.e.battery test and data processing, for obtainingthe modelparameters. Compared with existing methods, the proposed method has better accuracy and wider applications, and is easier to be implemented.

Key words： Power battery dynamics constant current curves equivalent circuit model
