Abstract
The present invention relates to a method for generating a security identifier for a control unit () of a battery system (), comprising the steps of supplying an operation voltage to the control unit (), outputting calibration data from a non-volatile memory element () of the control unit (), and generating a security identifier from the calibration data using a security algorithm. Therein, the calibration data is based on at least one testing process performed on the control unit () and is required for a faultless operation of the control unit (). Further, according to a method for generating an activation key for a control unit () of a battery system () an activation key is generated based on such security identifier and output from the control unit (). The invention further relates to an activation method for such control unit (), wherein a control unit () is activated in response to the validation of such security identifier. The present invention further relates to a control unit () for performing such methods and further relates to the use of calibration data for generating a security identifier.
