METHOD FOR DETERMINING AT LEAST ONE STATE OF A PLURALITY OF BATTERY CELLS, COMPUTER PROGRAM, BATTERY AND MOTOR VEHICLE

摘要

The invention relates to a method for determining at least one state of a plurality of spatially combined battery cells connected to each other by circuitry, wherein the state is determined by observing battery cells by means of at least one observer structure (20), and wherein a subset (nx) of a collectivity of battery cells (ntot) is observed and the state derived from the observation is determined for more battery cells (10) than for the observed battery cells (10). The invention further relates to a computer program, by means of which the method according to the invention can be carried out, and to a battery comprising a battery management system, which is designed such that the method according to the invention can be carried out thereby. The invention also relates to a motor vehicle comprising a battery according to the invention.
