Abstract:
A method for monitoring a state of a rechargeable battery based on a state value which characterizes the respective state of the rechargeable battery, characterized in that, during at least one time interval, an electrical energy which is output by the rechargeable battery and an electrical energy which is received by the rechargeable battery are detected, and in that an instantaneous state of charge or an instantaneous no-load voltage of the rechargeable battery is detected, wherein the detected electrical energy which is output by the rechargeable battery, the detected electrical energy which is received by the rechargeable battery and the respectively detected instantaneous state of charge or the respectively detected instantaneous no-load voltage of the rechargeable battery are evaluated in order to generate the state value.
