The present invention concerns the management of battery systems in order to determine the state of ageing parameter and state of charge parameter. The invention aims to reduce the calculation resources necessary for real-time estimation of such parameters. The invention concerns a method including a step (208) of estimating the state of ageing parameter and/or the current state of charge parameter by reading a predetermined mapping providing predetermined values of a state parameter dependent on a relative state of charge parameter (SOCen) and the state of ageing parameter as a function of predetermined values of the open circuit voltage (OCV). 本发明涉及电池系统的管理以确定老化状态参数和充电状态参数。本发明的目的在于减少用于实时地估算这些参数所需的计算资源。本发明涉及的方法包括通过读取预定图形估算老化状态参数和/或实际充电状态参数的估算步骤(208)，所述预定图形根据开路电压(OCV)的预定值提供状态参数的预定值，所述状态参数取决于相对充电状态参数(SOCen)和老化状态参数。
