Abstract
The invention relates to a method for controlling a security system of a charging station for charging electric vehicles, the security system comprising the following elements: a charging plug, the charging plug comprising a sensor unit for recording biometric data of a user that are used for authenticating the user on the security system, and a control unit for evaluating biometric data of the user. For this purpose, according to the invention, the control unit extracts a plurality of features from the biometric data of the user, and the control unit evaluates the features of the biometric data in a plurality of stages.
Claims20
A method for controlling a security system of an electric vehicle charging station for charging electric vehicles, the security system comprising a charging plug, wherein the charging plug comprising a sensor for recording biometric data of a user that are used for authenticating the user on the security system and a control unit for evaluating biometric data of the user;
- the method comprising, by the control unit:
- extracting, a plurality of features from the biometric data of the user;
- conducting a first stage, comprising first stage analyzing of at least some of the plurality of features to authenticate the user and to broadly separate out incorrect authentication attempts;
- based on a successful authentication in the first stage evaluation, selectively conducting a second stage to authenticate the user, comprising a second stage analyzing of at least some of the plurality of features, which second stage analyzing is more detailed compared to the first stage analyzing;
- and
- selectively authenticating the user for use of the electric vehicle charging stating based on the successful authentication of the user in the first stage and a successful authentication of the user in the second stage.
A security system for an electric vehicle charging station for charging electric vehicles, wherein the security system comprises:
- a charging plug, wherein the charging plug comprising a sensor for recording biometric data of a user;
- and
- a control unit, connected with the sensor for evaluating the biometric data of the user;
- wherein the control unit is configured to:
- extract a plurality of features from the biometric data of the user;
- conduct a first stage, comprising first stage analyzing of at least some of the plurality of features to authenticate the user and to broadly separate out incorrect authentication attempts;
- based on a successful authentication in the first stage, selectively conduct a second stage to authenticate the user, comprising a second stage analyzing of at least some of the plurality of features, which second stage analyzing is more detailed compared to the first stage analyzing;
- and
- selectively authenticate the user for use of the electric vehicle charging stating based on the successful authentication of the user in the first stage and a successful authentication of the user in the second stage.
