METHOD FOR ESTIMATING A STATE OF AN ELECTRICAL ENERGY-STORAGE SYSTEM, AND SYSTEM FOR DETERMINING A REMAINING CAPACITANCE OF AN ELECTRICAL ENERGY-STORAGE SYSTEM

摘要

The invention relates to a method for estimating a state of an electrical energy-storage system, in particular a motor vehicle starting battery, wherein, to this end, an internal resistance and/or an impedance of the energy-storage system and/or a variable coordinating with the internal resistance or the impedance of the energy-storage system is determined and is evaluated with regard to a remaining capacitance of the energy-storage system taking into consideration an age-related decrease in a maximum available capacitance of the energy-storage system.
