DETAILED DESCRIPTION OF THE EMBODIMENTS

[0065] FIG. 1 shows a schematic representation of an embodiment of the charging system 1 according to the invention for dynamic charging of electric vehicles 2 comprising one or more mobile devices 3 (for reasons of clarity, only one mobile device in an electric vehicle 2 is shown here as an example) which each comprise a navigation function or can be connected to a navigation device 22 in the respective electric vehicle 2 and a software application 4 installed and executed on the respective mobile device 3 as well as a plurality of mobile charging vehicles 5 each with a navigation apparatus 51 which is configured, inter alia, to transmit a current position P5 of each mobile charging vehicle 5 of charging system 1 to software application 4. The software application 4 is configured to display at least the next mobile charging vehicle 5 on the mobile device 3 located in an electric vehicle 2 and, in case of an electric battery 21 of the electric vehicle 2 to be charged, to transmit a charging request for this electric vehicle 2 as well as at least one current position P2 of the electric vehicle 2 to the displayed mobile charging vehicle 5, whereby the current position of the mobile device is equated with the current position P2 of the electric vehicle 2 since the mobile device 3 is located on board the electric vehicle 2. The navigation apparatus 51 of the charging vehicle 5 is in turn configured to transmit coordinates of a suitable common meeting point TP and a suitable meeting time TZ for charging the battery 21 of the electric vehicle 2 to the mobile device 3 in the electric vehicle 2 to be charged on the basis of the received charging request, whereby the software application 4 is configured to convert meeting point TP and meeting time TZ into navigation instructions for a driver of the electric vehicle 2 to be charged. The software application 4 can only generate the navigation instructions from the common meeting point TP and meeting time TZ for the electric vehicle 2 after transmitting a confirmation of the charging request at the common meeting point TP to the charging vehicle 5 via the software application 4. In an embodiment, the software application 4 can also be configured to display all positions P5 of all charging vehicles 5 to enable the selection of a desired charging vehicle 5 for charging the electric vehicle 2 by an operator of the mobile device (e.g. the driver of electric vehicle 2).

[0066] FIG. 2 shows a schematic representation of an embodiment of the electric vehicle 2 with an electric battery 21 for the operation of the electric vehicle 2 and with a mobile device 3 and inventive software application 4 installed on it. Here, the software application 4 can be configured to convert meeting point TP and meeting time TZ into navigation instructions for a driver of the electric vehicle 2 to be charged, wherein the software application 4 can display the current position P5 of the charging vehicle 5 on the way to the common meeting point TP on a navigation display in the electric vehicle 2. The navigation display can be the screen of the mobile device 3 or the screen of the navigation device 22 connected to the mobile device 3 in electric vehicle 2. For this purpose, the mobile device 3 can be connected to the navigation device 22 via a cable or an interface for wireless near field communication (e.g. Bluetooth). The software application 4 provides appropriate interfaces for data transfer to the navigation device 22. In one embodiment, the navigation apparatus 51 of the charging vehicle 5 can transmit the current position P5 of the charging vehicle 5 at least periodically to software application 4 for retrieval in the electric vehicle 2 on its way to the common meeting point TP until the charging vehicle 5 has reached the common meeting point TP.

[0067] FIG. 3 shows a schematic representation of the calculation of the common meeting point TP based on position and movement data of the electric vehicle 2 as well as the routes FRE, FRL of the charging vehicle 5 and the electric vehicle 2 to the common meeting point TP. Provided that together with the charging request only the current position P2 of the electric vehicle 2 is transmitted to the displayed mobile charging vehicle 5, the navigation apparatus 51 of the charging vehicle 5 can, without knowledge of the previous route BR and the planned future route GR of the electric vehicle 2, use only a meeting point area TG1 (circle represented by a dash point line) around the current position P2 of the electric vehicle 2 to calculate an appropriate common meeting point TP, the diameter of which is determined, for example, by the road conditions and assumed speeds of the two vehicles 2, 5. If, on the other hand, the common meeting point TP and the meeting time TZ are determined by the navigation apparatus 51 of the mobile charging vehicle 5 taking into account a previous route BR of the electric vehicle to be charged 2, another meeting point area TG2 can be assumed on the basis of the assumption that the previous route will continue approximately in the same way, extrapolating the previous route BR of the electric vehicle 2 into a corresponding forward movement, here represented as a dashed drop-shaped area TG2. A common meeting point in area TG2 disturbs the route of the electric vehicle 2 significantly less than a meeting point in area TG1 based only on the current position P2 of the electric vehicle 2 at the time of transmission of the charging request. For this purpose the software application 4 transmits the previous route BR based on correspondingly recorded position data with the charging request to the mobile charging vehicle 5. If the software application 4 transmits in addition to the previous route BR also the route GR planned for the electric vehicle 2 up to a route destination RZ to the charging vehicle 5, the navigation apparatus 51 of the charging vehicle 5 can take into account the planned route GR for the calculation of the common meeting point TP and the meeting time TZ as shown in FIG. 6. Here the common meeting point TP is exactly on the planned route GP of the electric vehicle 2 to the route destination RZ. Therefore, the planned charging of the battery 21 of the electric vehicle 2 does not interfere with the route BR,GR of the electric vehicle 2 at all, since the common meeting point TP and the driving distance FRE of the electric vehicle 2 to the meeting point TP corresponds to the planned route GR and therefore no detours and additional driving times have to be accepted. The navigation apparatus 51 of charging vehicle 5 can automatically calculate the fastest route for charging vehicle 5 to the meeting point TP and display it as driving route FRL in charging vehicle 5.

[0068] FIG. 4 shows a schematic representation of the charging vehicle 5 according to the invention, which in this case has a battery storage 52 of more than 300 kWh and a DC charging unit 53 and an AC charging unit 54 in addition to the navigation apparatus 51. Other charging vehicles may also have more DC and/or AC charging units 53, 54. The multiple charging units 53, 54 enable simultaneous charging of several 2 electric vehicles 2 each with battery 21 and mobile devices 3, on which the software applications 4 are installed and executed.

[0069] FIG. 5 shows a schematic representation of the data storage product 10 according to the invention with software application 4 stored thereon, which is suitable for the execution of the steps of method 100 according to FIG. 9, which are related to software application 4. Data storage products 10 can be any memory suitable for storing software programs such as software applications, for example data sticks, CDs, hard disks, servers and other devices suitable for this purpose.

[0070] FIG. 6 displays a schematic representation of an embodiment of the method according to the invention 100 for dynamic charging of electric vehicles in a charging system according to the invention comprising a software application 4 installed and executed at least on a mobile device 3, which comprises a navigation function or can be connected to a navigation device 22 respectively, and a plurality of mobile charging vehicles 5 each with a navigation apparatus 51. In this embodiment, the method comprises the steps of transmitting 110 of current positions P5 of each mobile charging vehicle 5 of the charging system 1 to the software application 4 by the navigation apparatus 51 of the charging vehicle 5; of displaying 120 at least the next mobile charging vehicle 5 on the mobile device 3 located in an electric vehicle 2 by the software application; transmitting 130 by the software application a charging request for the electric vehicle 2 and at least one current position P2 of the electric vehicle 2 to the indicated mobile charging vehicle 5 in the case of an electric battery 21 of the electric vehicle 2 to be charged; transmitting 140 coordinates of a suitable common meeting point TP and a suitable meeting time TZ for charging the battery 21 of the electric vehicle 2 on the basis of the received charging request to the mobile device 3 in the electric vehicle 2 to be charged in the electric vehicle 2 by the navigation apparatus 51 of the charging vehicle 5; and converting 150 of meeting point TP and meeting time TZ into navigation instructions for a driver of the electric vehicle to be charged 2 by the software application 4 for navigating the electric vehicle 2 to the common meeting point TP. In an embodiment (dotted arrow), the method comprises the additional step of at least periodically transmitting 170 the current position P5 of the charging vehicle 5 on a way to the common meeting point by the navigation apparatus 51 to the software application 4 for a retrieval the electric vehicle 2 and displaying 180 the current position P5 of the charging vehicle 5 on the way to the common meeting point TP by the software application 4 on a navigation display in the electric vehicle 2. Subsequent to step 130, the method may comprise the additional step of determining 160 the common meeting point TP and the meeting time TZ taking into account at least one previous route BR of the electric vehicle to be charged 2 from the navigation apparatus 51 of the mobile charging vehicle 5, wherein the software application 4 transmitted the previous route BR to the mobile charging vehicle 5 together with the charging request on the basis of correspondingly recorded position data. Furthermore, in addition to the previous route BR, the software application 4 can also transmit the route GR planned for the electric vehicle 2 up to a route destination RZ to the charging vehicle 5, and the navigation apparatus 51 of the charging vehicle 5 can take into account the planned route GR for calculating 160 of the common meeting point TP and the meeting time TZ.

[0071] The embodiments shown here are only examples of the present invention and must therefore not be understood in a restrictive way. Alternative embodiments considered by the skilled person are equally covered by the scope of protection of the present invention.
