Method for determining a damage rate of a battery cell for an electrical energy store of a motor vehicle, method for determining a settable pressure, computer program product, computer-readable storage medium, electronic computing device and pressure control device

Abstract

The invention relates to a method for determining a damage rate (DC) of a battery cell (16) for an electrical energy store of an at least partially electrically driven motor vehicle by means of an electronic computing device (12), the method comprising the following steps: determining a capacity degradation of the battery cell (16) depending on a force generated as a result of a cell swelling of the battery cell (16); determining an ageing condition (SOH) of the battery cell (16); and determining the damage rate (DC) depending on the capacity degradation and the ageing condition (SOH).
