Abstract
The present invention relates to a method of estimating the internal state of an electrochemical system by a zero-dimensional (0D) electrochemical mathematical model for estimating the characteristics of a battery that are not directly measurable during operation thereof. For applications relating to hybrid and electric vehicles, the most significant internal characteristics are the state of charge (SoC), the state of health (SoH) and the thermal state (T). Reconstruction of the internal characteristics is achieved using a mathematical model of the battery. The method can be used with the operation of the battery itself (real time) with a concentrated-parameter (0D) or off-line mathematical model, for calibration, an optimization or a validation of management and estimation strategies. The method allows simulation of the thermal and electrical behavior of a battery. The method according to the invention can also be useful for battery dimensioning and for optimization of the energy and thermal management strategies as a function of the desired application.
