Abstract
A method is provided in which a pair of transmitters having omnidirectional and directional transmission characteristics is provided when an associative connection is established between an electric vehicle and a charging station. Once the associative connection has been established in such a way that a directional radio link is formed, the associative connection is tested using an omnidirectional transmitter. The results of the testing may be used to prevent an unwanted associative connection to a compromising transmitter.
Claims10
A method for making an associative connection between an electric vehicle and a charging station, the method comprising:
- setting up the associative connection between the electric vehicle and the charging station by forming a directional radio link;
- and
- checking the associative connection between the electric vehicle and the charging station using an omnidirectional transmitter.
A connecting unit for establishing an associative connection between an electric vehicle and a charging station, the connecting unit comprising:
- an interface to at least one first transmitter, each first transmitter having an essentially directional transmission characteristic;
- and
- an interface to at least one second transmitter, each second transmitter having an essentially omnidirectional transmission characteristic;
- wherein the connecting unit is configured to use the first transmitter to set up the associative connection between the electric vehicle and the charging station;
- and
- wherein the connecting unit is configured to use the second transmitter to check the associative connection between the electric vehicle and the charging station.
An electric vehicle, comprising:
- a connecting unit comprising:
- an interface to at least one first transmitter, each first transmitter having an essentially directional transmission characteristic;
- and
- an interface to at least one second transmitter, each second transmitter having an essentially omnidirectional transmission characteristic;
- wherein the connecting unit is configured to use the first transmitter to set up the associative connection between the electric vehicle and the charging station;
- and
- wherein the connecting unit is configured to use the second transmitter to check the associative connection between the electric vehicle and the charging station.
A charging station, comprising:
- a connecting unit comprising:
- an interface to at least one first transmitter, each first transmitter having an essentially directional transmission characteristic;
- and
- an interface to at least one second transmitter, each second transmitter having an essentially omnidirectional transmission characteristic;
- wherein the connecting unit is configured to use the first transmitter to set up the associative connection between the electric vehicle and the charging station;
- and
- wherein the connecting unit is configured to use the second transmitter to check the associative connection between the electric vehicle and the charging station.
