Abstract
A battery system for an electric vehicle includes a battery module having battery cells and a controller module connected to the battery cells, the controller module being configured to measure voltage values, current values, and temperature values of at least one of the battery cells, and a controller unit connected to the battery module and configured to communicate with the controller module via a data line, the controller unit being configured to determine an inherent physical property of the at least one of the battery cells based on the measured values of the controller module, to compare the determined inherent physical property with a reference value for the inherent physical property, and to perform an authentication of the at least one of the battery cells based on the comparison.
