Abstract

Embodiments relate to initiating a charging process of an electric vehicle according to predefined charging preferences. An association between the electric vehicle and a user profile including the predefined charging preferences is established. The user profile is stored in a memory within a distributed processing network. A charging request message related to the electric vehicle is provided to a remote charging request message processor of the distributed processing network, the charging request message indicating a charging need of the electric vehicle. The charging request message is processed using the user'"'"'s predefined charging preferences stored in the user profile to obtain user specific result data, including information on one or more charging stations corresponding to the predefined charging preferences. From the remote charging request message processor, a result message related to the electric vehicle is provided including the obtained user specific result data for initiating the charging process.

Claims

1. A method for reserving a charging station for an electric vehicle according to predefined charging preferences, the method comprising:

establishing an association between the electric vehicle and a user profile comprising the predefined charging preferences, the predefined charging preferences comprising at least one filter criterion for filtering results in response to a charging request message, the filter criterion comprising at least one criterion of the group of electrical charge pricing of interest, charging station type of interest, charging station provider of interest, and a preferred charging station reservation period, wherein the user profile is stored in a memory within a distributed processing network;

when a current state of charge of the electric vehicle falls below a minimum state of charge defined by the user profile, and depending on a way of driving the electric vehicle, providing the charging request message related to the electric vehicle to a remote charging request message processor of the distributed processing network, the charging request message indicating a charging need of the electric vehicle, wherein the charging request message is initiated from a processor module installed within the electric vehicle, the processor module having access to navigational or charging state data of the vehicle;

processing the charging request message using the user'"'"'s predefined charging preferences stored in the user profile to obtain user specific result data, the user specific result data comprising information on a list of available charging stations corresponding to the predefined charging preferences and a time of obtaining the user-specific result data; and

providing, from the remote charging request message processor, a result message related to the electric vehicle in response to the charging request message, the result message comprising the obtained user specific result data for initiating the charging process; and

reserving a charging station meeting the user'"'"'s predefined charging preferences based on the user specific result data.

2. The method of claim 1, wherein processing the charging request message is further based on charging station information provided to the remote charging request message processor by at least one charging station provider the charging station information comprises at least one of the group of geographical location data of charging stations, availability of charging stations, type of charging station, and pricing of a charging station.

3. The method of claim 2, wherein the obtained user specific result data comprises a match between the user'"'"'s predefined charging preferences and the charging station information provided by the at least one charging station provider.

4. The method of claim 2, wherein the charging station information is provided essentially in real-time by the at least one charging station provider.

5. The method of claim 1, wherein said charging station is reserved based on at least an expected arrival time of the electric vehicle at said charging station.

6. The method of claim 1, wherein the user profile comprises an identification of the electric vehicle.

7. The method of claim 6, wherein establishing the association further comprises obtaining a unique authentication code indicating the association between the electric vehicle and the user profile.

8.
