A method for monitoring a state of a rechargeable battery on the basis of a state value characterizing the respective state of the rechargeable battery

摘要

The invention relates to a method for monitoring a state of an accumulator, in particular a lithium-ion accumulator, on the basis of a state value characterizing the respective state of the accumulator, characterized in that during at least one time interval an electrical energy emitted by the accumulator and one by the accumulator recorded electrical energy are recorded and that a current state of charge or an instantaneous open circuit voltage of the accumulator is recorded, the recorded electrical energy output by the accumulator, the recorded electrical energy absorbed by the accumulator and the respectively detected current charge state or the respectively detected current open circuit voltage of the accumulator can be evaluated to generate the state value.
