Abstract
The present invention concerns an adapter system for a motor vehicle which comprises at least one adapter of the adapter system and a measuring method for a motor vehicle in which the electrical energy transmitted to the motor vehicle is documented in a server unit for a price statement via the motor vehicle independently of the charging device.
Claims15
An adapter system comprising a first adapter which has an electrical energy measuring device for measuring an electrical energy absorbed or emitted by a motor vehicle a first communication module for a wireless first data connection with a server unit and a second communication module a second adapter has the second communication module for providing a second data connection to the first adapter and an interface which is set up to be connected to a data bus system of the motor vehicle in order to read out a vehicle identification number via the data bus system
A motor vehicle comprising a second adapter of an adapter system for measuring a charging current from a charging device, the second adapter being in the form of a control unit of the motor vehicle
A measuring method for at least one of:
- supplying and receiving electrical energy for a motor vehicle at a charging device by means of an adapter system and a server unit comprising the following steps:
- reading a vehicle identification number of the motor vehicle via an interface and a corresponding data bus interface to a data bus system of the motor vehicle by means of a second adapter of the adapter system;
- transmission of the vehicle identification number by means of a second communication module of the second adapter via a second data connection to a first adapter of the adapter system;
- storing the vehicle identification number in a memory of the first adapter;
- transmission of an adapter identification number of the first adapter together with the vehicle identification number by means of a first communication module of the first adapter via a first data connection to the server unit;
- comparison by the server unit of the adapter identification number sent and the vehicle identification number with an adapter identification number and a vehicle identification number stored in a database of the server unit;
- transmission of a release signal by the server unit to the first adapter by means of the first communication module via the first data connection to start a transmission process of electrical energy, if the transmitted adapter identification number and vehicle identification number match the adapter identification number and vehicle identification number stored in the database;
- reading a vehicle identification number of the motor vehicle via an interface and a corresponding data bus interface to a data bus system of the motor vehicle by means of a second adapter of the adapter system;
- transmission of the vehicle identification number by means of a second communication module of the second adapter via a second data connection to a first adapter of the adapter system;
- storing the vehicle identification number in a memory of the first adapter;
- transmission of an adapter identification number of the first adapter together with the vehicle identification number by means of a first communication module of the first adapter via a first data connection to the server unit;
- comparison by the server unit of the adapter identification number sent and the vehicle identification number with an adapter identification number and a vehicle identification number stored in a database of the server unit;
- and
- transmission of a release signal by the server unit to the first adapter by means of the first communication module via the first data connection to start a transmission process of electrical energy, if the transmitted adapter identification number and vehicle identification number match the adapter identification number and vehicle identification number stored in the database
