Abstract
The invention relates to a computer-implemented method for predictively detecting a malfunction of a device battery of a technical device after an operating disturbance occurs in the technical device, comprising the following steps: providing a temporal operating variable profile, the operating parameter change curve over time represents the operation of the technical equipment and the equipment battery; determining an operating disturbance by evaluating the operating variable curve over time; when determining the operating disturbance, determining at least one disturbance event characteristic indicating the state of the technical device and at least one battery state variable indicating the state of the device battery, and evaluating the at least one disturbance event characteristic and the at least one battery state variable by means of a data-based disturbance event model; an output vector generator for obtaining an output vector having output variables, the values of which are each assigned to a fault type of the fault; and notifying a user of the technical device of the processing indication as a function of the output vector.
