Abstract

The invention relates to a method for providing data for activating a charging station (200), comprising the following steps carried out by a charging cable (100) for connecting the charging station (200) to a vehicle (300): identifying (310) a plug-in process of the charging cable (100); determining a current location (321) of the charging cable; and transmitting (320) the determined location (321) and an identifier (322) of the charging cable (100). The invention also relates to a method for activating a charging station (200), comprising the following steps carried out by a (further) computer unit (400) at a distance from the charging station (200): receiving (330) a location (321) and an identifier (322) of a charging cable (100); determining (340) a charging station (200) to be activated based on the received location (321); and initiating (360) the activation of the determined charging station (200) for a charging process.

Abstract

The present invention relates to an operating method (100) for a fuel cell system (300). The operating method (100) comprises: - determining (101) a first state of the fuel cell system (300) at a first time; - on the basis of the first state, setting (103) an interval time and/or an amplitude for an input of moisture in an intermittent mode, in which there is a repeated alternation between a humidifying mode and a drying mode; - determining (105) a second state of the fuel cell system (300) at a second time that is subsequent to the first time; - on the basis of the second state, setting (107) a corrected interval time and/or a corrected amplitude for the input of moisture in the intermittent mode; - ascertaining (109) a difference between the interval time and/or the amplitude set during the initial setting operation and the corrected interval time and/or the amplitude for the input of moisture in the intermittent mode; - assigning (111) a characteristic value of the ascertained difference according to a predefined assignment scheme; - outputting (113) the characteristic value on an output unit.

Abstract

The present invention relates to a method for operating a fuel cell (1) of a fuel cell system (2) for a vehicle. According to the method, a predetermined load reduction is implemented in stages so that, combined with cooling of the fuel cell (1), unacceptable operating conditions, which can, for example, lead to increased wear of the fuel cell (1), are avoided. The invention also relates to a fuel cell system (2) for a vehicle.

Abstract

A method includes receiving audio stream data associated with a data capture environment, and receiving sensor data associated with the data capture environment. The method also includes identifying at least some events in the sensor data, and calculating at least one offset value for at least a portion of the audio stream data that corresponds to at least one event of the sensor data. The method also includes synchronizing at least a portion of the sensor data associated with the portion of the audio stream data that corresponds to the at least one event of the sensor data, and labeling at least the portion of the audio stream data that corresponds to the at least one event of the sensor data. The method also includes generating training data using at least some of the labeled portion of the audio stream data, and training a machine learning model using the training data.
