Method and system for proving a charging contract of a user for enabling a charging process for charging an electric vehicle at a charging infrastructure

摘要

The invention relates to a method for proving a charging contract of a user for enabling a charging process for charging an electric vehicle at a charging infrastructure (14), comprising the following steps: a) generating a feature associated with the charging contract of the user by a power supplier (10) (step 100, Step 300); b) encrypted transmission of the feature associated with the load contract of the user from the towing provider into a secure memory of the mobile terminal (12) of the user (step 120, step 320); c) transmitting data from at least the mobile terminal to the charging infrastructure using the feature associated with the user's loading contract (step 140, step 340); d) checking the data received from the charging infrastructure using a feature associated with the charging contract of the user (step 220, step 360); and e) enabling the charging process by the charging infrastructure upon successful verification (step 240, step 380). The invention further relates to a corresponding system for proving a charging contract of a user for enabling a charging process for charging an electric vehicle to a charging infrastructure (14).
