DETAILED DESCRIPTION

[0027] FIG. 1 shows in a schematic side view an embodiment of a battery charging assistance system 10. The battery charging assistance system is external to a motor vehicle 12, wherein the motor vehicle 12 is at least partially electrically operated. In particular, the motor vehicle 12 is fully electrically operated such that the motor vehicle 12 can comprise a battery 14 which can be, in particular, a high voltage battery. The battery charging assistance system 10 at least comprises a communication device 16.

[0028] A method for operating the battery charging assistance system 10 can be realized through the battery charging assistance system 10. A charging request 18 and an actual position P of the motor vehicle 12 are transmitted from the motor vehicle 12 to the battery charging assistance system 10 by a first communication network 20. This communication network 20 can be, for example, a mobile network. Depending on the position P and the charging request 18, the battery charging assistance system 10 may choose a battery charging station 22 out of a plurality of battery charging stations and the one battery charging station 22 is reserved from the battery charging assistance system 10 by transmitting a reservation signal 24 to the one battery charging station 22 by a second communication network 26. The second communication network 26 can be, for example, a mobile network.

[0029] It is provided that if the one battery charging station 22 is occupied by a further at least partially electrical operated motor vehicle 28, which is also referred to as further motor vehicle 28, a leaving message is computed from the one battery charging station 22 and/or the battery charging assistance system 10, which is shown in FIG. 1, and transmitted to the further motor vehicle 28 in order to ask the further motor vehicle 28 to leave the one battery charging station 22 and if the further motor vehicle 28 is leaving the one battery charging station 22, a compensation action 32 for the further motor vehicle 28 is initiated by the battery charging assistance system 10.

[0030] FIG. 1 shows further that a connection sensor 34 of the at least one battery charging station 22 is detecting a connection and/or a disconnection of the further motor vehicle 28 at the one battery charging station 22. In particular, a connection status of the at least one battery charging station 22 is transmitted to the battery charging assistance system 10.

[0031] In particular, a state of charge of the battery 14 of the motor vehicle 12 is monitored by an electronical computing device 36 of the motor vehicle 12 and depending on the monitored state of charge, the charging request 18 is transmitted to the battery charging assistance system 10. In particular, the charging request 18 is transmitted when a predefined state of charge threshold of the state of charge of the battery 14 is reached and monitored by the electronical computing device 36.

[0032] FIG. 1 shows further that an actual route 38 of the motor vehicle 12, which is provided by a navigation device 40 of the motor vehicle 12, is taken into consideration by choosing the one battery charging station 22 out of the plurality of battery charging stations by the battery charging assistance system 10.

[0033] The compensation action 32, for example, covers a payment for the further motor vehicle 28 and/or a cheaper charging fee for a current charging and/or a future charging for the further motor vehicle 28 and/or a discount on a system of the battery charging assistance system 10.

[0034] Furthermore, FIG. 1 shows that after the transmission of the leaving message 30 to the further motor vehicle 28, a user of the further motor vehicle 28 is asked to confirm the leaving and the confirmation is transmitted to the battery charging assistance system 10. Furthermore, it is shown that after the reservation of the one battery charging station 22 a reservation confirmation 42 is transmitted to the motor vehicle 12.

[0035] FIGS. 2A-2C show a schematic flow chart according to an embodiment of the method. In a first step S1 the method starts. In a second step S2, the battery charging assistance system 10, which can also be called an original equipment manufacturer (OEM) back-end, receives from the motor vehicle 12 a critical state of charge notification. In a third step S3, the OEM back-end 10 identifies at least one close by battery charging station 22. In a fourth step S4, an OEM back-end 10 requests to identify at least one in-network further motor vehicle 28 charging at the battery charging station 22. If the at least one in-network further motor vehicle 28 is charging at the at least one identified battery charging station 22, a fifth step S5 is performed, where the OEM back-end 10 requests to identify the at one least in-network further motor vehicle 28 and requests that the at least identified in-network further motor vehicle 28 ends the charging session. In the fifth step S5, the OEM backend may request the at least one identified in-network further motor vehicle 28 to leave the battery charging station 22, thereby ending the charging session of the at least one identified further motor vehicle 28, by providing the motor vehicle's 12 arrival time to the at least one battery charging station 22 and providing a compensation action 32, which may also be referred to as an incentive, to the at least one identified further motor vehicle 28. The method then proceeds to a sixth step S6 where the at least one further motor vehicle 28, also referred to as the responding vehicle, approves the request.

[0036] If the responding further motor vehicle 28 agrees to end the charging session, the method goes to a seventh step S7, where it is determined by the OEM back-end 10 if there are more than one responding further motor vehicle 28. If there are more than one responding further motor vehicle 28 that approved the request by the requesting motor vehicle 12, the method proceeds to an eighth step S8, in which the OEM back-end 10 selects the responding further motor vehicle 28 at a battery charging station 22 with the highest charging power and shortest distance to the requesting vehicle 12. From the eighth step S8 a ninth step S9 is performed, where the OEM back-end 10 shares the location of the available battery charging station 22 with the requesting motor vehicle 12 and confirms that the selected responding further motor vehicle 28 will end the charging session by at least the time of arrival of the requesting vehicle 12 at the battery charging station 22. From the seventh step S7, if there is just one responding further motor vehicle 28, the method proceeds from the seventh step S7 to the ninth step S9. Coming from the ninth step S9, a tenth step S10 is provided wherein the responding further motor vehicle 28 ends the charging session, leaves the battery charging station 22 and the requesting motor vehicle 12 arrives to the battery charging station 22, and incentives are distributed by the charging assistance system 10 as per the compensation action 32. In an eleventh step S11, the method ends.

[0037] Coming from the fourth step S4, if there is no in-network further motor vehicle 28 charging at the at least one identified battery charging station 22, the responding further motor vehicle 28, through the OEM back-end 10, identifies alternative motor vehicles, which may be out-of-network motor vehicles, charging at the at least one identified battery charging station 22 in a twelfth step S12. The twelfth step S12 can also be performed after the sixth step S6, if, for example, the at least one responding in-network further motor vehicle 28 disagrees to end the charging session. After the twelfth step S12, a thirteenth step S13 is performed, wherein the identification of at least one out-of-network vehicle charging close by is performed by the responding further motor vehicle 28 through the OEM back-end 10. If the OEM back-end 10 identifies at least one out-of-network motor vehicle charging at the at least one identified battery charging station 22, a fourteenth step S14 is performed. In the fourteenth step S14, the responding further motor vehicle 28, through the OEM back-end 10, requests that the at least one identified out-of-network motor vehicle ends their charging session and leave the charging station 22 by providing the requesting motor vehicle 12 arrival time and a compensation action 32. From the fourteenth step S14, a fifteenth step S15 is performed, wherein the responding out-of-network vehicle approves the request. If the responding out-of-network vehicle agrees to end the charging session, a sixteenth step S16 is performed, wherein the responding further motor vehicle 28, through the OEM back-end 10, communicates the responding out-of-network vehicle approval with the requesting motor vehicle 12 through the OEM back-end 10. After the sixteenth step S16, the seventh step S7 can be performed.

[0038] Coming from the thirteenth step S13, if there is no out-of-network motor vehicle charging at the identified battery charging station 22, a seventeenth step S17 is performed, wherein the at least one responding battery charging station 22 back-end attempts to identify charging motor vehicles present at the at least one battery charging station 22. In an eighteenth step S18, the at least one battery charging station 22 back-end is confirming the identification of at least one motor vehicle at the at least one charging station 22. If, in the eighteenth step S18, at least one motor vehicle is confirmed to be charging at the at least one battery charging station 22, a nineteenth step S19 is performed. In the nineteenth step, the responding battery charging station 22 back-end requests the at least one identified charging motor vehicle to end charging and leave by providing the requesting motor vehicle 12 arrival time at the at least one identified battery charging station 22 and providing a compensation action 32. After the nineteenth step S19, a twentieth step S20 is performed, wherein the at least one identified vehicle is approving the request. If the at least one identified motor vehicle approves to end the charging session, a twenty-first step S21 is performed, wherein the at least one identified battery charging station 22 back-end shares the at least one identified motor vehicle approval to the requesting motor vehicle 12 through the OEM back-end 10. After the twenty-first step S21, the seventh step S7 can be performed.

[0039] Coming from the fifteenth step S15, if the responding out-of-network vehicle disagrees to end the charging session, the seventeenth step S17 can be performed.

[0040] Coming from the eighteenth step S18, if there is no charging motor vehicle identified at the battery charging station 22, or, coming from the twentieth step S20, if the charging motor vehicle disagrees to end the charging session, the eleventh step S11, in other words, the end of the method, is performed.
