Resumen de: WO2023006505A1

The invention relates to the field of battery management systems (BMSs). It is particularly advantageously used in the management of cells, modules or packs for electrochemically storing energy. The premise on which the proposed model is based is that the form of the discharge voltage follows, within a homothety and a translation, a single curve, regardless of the mode of discharge. The simplified and improved diagnosis and monitoring of the behaviour of a battery (i.e. state of charge/state of health), and the subsequent simplified and improved management thereof, in particular when high depths of discharge and/or high speeds are used, are advantageously achieved. Indeed, estimating the state-of-charge values of the battery from discharge voltage and current measurements is greatly facilitated thereby.
