[0007] The invention is based on the objects of providing a method for transmitting data between a vehicle and a delivery device which delivers at least one energy source to the vehicle, a communication arrangement for a delivery device and such a delivery device which facilitate an estimation of an ecological footprint of the vehicle.

[0008] These objects are achieved by a method for transmitting data between a vehicle and a delivery device that delivers at least one energy source to the vehicle, having the features of patent claim 1, by a communication arrangement for such a delivery device having the features of patent claim 4, and by a corresponding delivery device that delivers at least one energy source to the vehicle, having the features of patent claim 6. Advantageous embodiments with expedient further developments of the invention are specified in the dependent patent claims.

[0009] In order to provide a method for transmitting data between a vehicle and a delivery device that delivers at least one energy source to the vehicle, which facilitates estimating an ecological footprint of the vehicle, data associated with a selected energy source comprise second information about the origin of the selected energy source and third information about the composition of the selected energy source. Furthermore, the data associated with the selected energy source comprise fourth information about a climate footprint of the selected energy source. For example, the fourth information can contain carbon dioxide values ​​that correspond to the amount of carbon dioxide released during the production and / or transport of the deliverable energy source. This advantageously makes the calculation of a carbon dioxide tax more transparent for the user.In addition, the user can choose alternative energy sources that are transported over shorter distances or that are produced using a manufacturing process with lower carbon dioxide emissions.

[0010] In order to provide a communication arrangement for a dispensing device that dispenses at least one energy source to the vehicle, and to provide such a dispensing device that facilitates estimating the vehicle's ecological footprint, at least one first evaluation and control unit transmits data containing second information about the origin of the selected energy source and / or third information about the composition of the selected energy source via at least one device-side first communication unit to at least one vehicle-side second communication unit. Furthermore, the at least one first evaluation and control unit transmits data containing fourth information about the carbon footprint of the selected energy source via the at least one device-side first communication unit to the at least one vehicle-side second communication unit.At least one second evaluation and control unit can be arranged in the vehicle, which evaluates and / or processes the data received from the at least one vehicle-mounted second communication unit and outputs it to a vehicle user via an output unit. The output unit can advantageously correspond to a mobile phone or an infotainment system present in the vehicle. By evaluating and / or processing and outputting the received data, the received data and the information contained therein are advantageously presented to the vehicle user in an understandable manner.

[0011] A method for transmitting data between a vehicle and a dispensing device that dispenses at least one energy source is understood below as a sequence of method steps in which each energy source dispensed by the dispensing device is assigned data containing first information about the type of the corresponding energy source, second information about the origin of the selected energy source, and third information about the composition of the selected energy source. Furthermore, an energy source is selected for dispensing to the vehicle, and the data associated with the selected energy source is transmitted to the vehicle.

[0012] Such a dispensing device, which dispenses at least one energy source, is understood below to mean an assembly with at least one communication arrangement and at least one column. The at least one column comprises at least one energy source transmission element, which can be coupled to a vehicle-side receiving element. Data with first information about the type of a selected energy source, second information about the origin of the selected energy source, and third information about the composition of the selected energy source are output to the at least one vehicle via the at least one communication arrangement. The dispensing device can, for example, recognize a selection of an energy source by a user coupling the energy source transmission element assigned to the energy source to the receiving element of the vehicle.

[0013] A corresponding communication arrangement is understood below to mean an assembly with at least one device-side first communication unit, at least one vehicle-side second communication unit, and at least one first evaluation and control unit, wherein the at least one first evaluation and control unit assigns corresponding data to each energy source. The at least one first evaluation and control unit outputs data of the selected energy source to the at least one vehicle-side second communication unit via the at least one device-side first communication unit, wherein the data comprises first information about the type of the corresponding energy source, second information about the origin of the selected energy source, and third information about the composition of the selected energy source.The communication arrangement according to the invention is advantageously suitable for carrying out the method according to the invention for transmitting data between a vehicle and a delivery device. A wireless connection can transmit the data between the at least one device-side first communication unit and the at least one vehicle-side second communication unit. Only minor modifications to the delivery device for outputting at least one energy carrier are required. Alternatively, a data transmission line can transmit the data between the at least one device-side first communication unit and the at least one vehicle-side second communication unit. The data transmission line can be coupled to an energy carrier transmission element of the delivery device.Additionally, the vehicle can transmit data to the output device according to the invention via the communication arrangement according to the invention. For example, the current fill level of a tank or the charge status of a battery can be output to the output device.

[0014] In the following, an energy source is understood to be a medium with which the vehicle can be powered. An energy source is usually selected by a user to suit the vehicle's drive system. The user selects an energy source transfer element via which the energy source is transferred from the column to the vehicle. The energy sources can be, for example, liquid fuels such as gasoline, diesel, etc., or gaseous fuels such as hydrogen, natural gas, etc., or electrical current for charging an energy storage device such as a battery in the vehicle. These energy sources can, for example, be obtained from natural fossil raw materials such as crude oil, coal or natural gas, or from renewable raw materials such as biomass, or from regenerative sources such as hydropower, wind power or solar energy. In addition, the energy source "electricity" can be obtained from a nuclear fuel such as uranium or plutonium.The different energy sources have different effects on the life cycle assessment and thus on the ecological footprint of the vehicle depending on their production, origin, disposal and application. The second information about the origin of the energy source relates to the type of production of the selected energy source or the country(ies) in which the energy source is extracted and / or processed. The third information about the composition of the selected energy source includes, for example, an electricity mix of the electricity output or a composition of biodiesel or biogasoline, whereby the proportion of fuel derived from petroleum and the proportion of fuel derived from plants is output. In addition, the proportion of fuel derived from regional plants and the proportion of fuel derived from imported plants, such as palm oil, can be output.In addition, the proportion of fuel produced using renewable energy can be displayed.

[0015] The data output allows users to advantageously understand whether their chosen energy source meets their requirements, particularly their ecological requirements. For example, the user can stop or even not initiate a supply of the energy source if the energy source does not meet their requirements and alternatives exist. For example, an electricity mix with a high proportion of electricity from nuclear power plants and / or from power plants that burn fossil fuels can be rejected. Furthermore, fossil natural gas can be replaced with biogas from ethanol. Furthermore, a fuel blended with palm oil can be replaced with one without palm oil. Furthermore, domestic energy sources can be given preference over imported energy sources. The data can also contain fifth information about additional taxation if this applies to the selected energy source.The provided data advantageously provides users with greater transparency about the composition of their preferred energy source and its origin, thus facilitating their decision as to whether to use this energy source to power their vehicle or to choose an alternative. Furthermore, this information enables users to make informed decisions. If a user doesn't know where and how their preferred energy source is produced, or what its composition is, they cannot select alternatives.

[0016] In a further advantageous embodiment of the method according to the invention, the data assigned to the selected energy source can be evaluated and / or processed in the vehicle and output to a vehicle user. Data and information on the energy sources from previous recording processes can be saved and incorporated into the evaluation or processing of the data. For example, a current energy mix or an average energy mix can be output to the vehicle user. Derived values ​​can also be determined, e.g. the current energy mix in the battery or the tank, which can be calculated from the last recording processes. Alternatively or additionally, the data can be made available to other control units, for example to determine and record the resulting CO2 emissions.By evaluating and / or processing the received data and displaying it, the received data and the information it contains are presented to the vehicle user in a beneficial and understandable manner. For example, car-sharing users can be provided with transparent information about the energy mix and thus also about the ecological footprint caused by the energy source.

[0017] In an advantageous embodiment of the delivery device according to the invention, the at least one energy source can be an electric current, wherein the column is designed as a charging column and the energy transmission element is designed as an induction transmitter coil or as a cable with a charging plug or a plug receptacle. The corresponding vehicle-side receptacle element can be designed as an induction receiver coil, a plug receptacle, or a plug. Suitable batteries in the vehicle can be charged using the current. Furthermore, the data can be easily transmitted to the induction receiver coil via the cable or wirelessly via the induction transmitter coil.

[0018] In an alternative embodiment of the dispensing device according to the invention, the at least one energy source can be a gaseous or liquid fuel, wherein the column is designed as a fuel pump and the energy transmission element is designed as a hose with a first coupling element, which can be coupled to a vehicle-side receiving element designed as a second coupling element. The first coupling element can be designed, for example, as a fuel nozzle, which can be coupled to a receiving element designed as a tank nozzle. Furthermore, fluid-tight couplings can be created between the first coupling element and the second coupling element, which are suitable for natural gas, ethanol, hydrogen, or other gaseous or potentially hazardous energy sources.

[0019] The advantages and preferred embodiments described for the method according to the invention also apply to the communication arrangement according to the invention and to the dispensing device according to the invention.

Additionally or alternatively, the second evaluation and control unit 17 processes the data D received from the vehicle-side second communication unit 14. For this purpose, data D from previous energy source outputs can be stored in a memory unit (not shown) and used for evaluation.The second evaluation and control unit 17 outputs the evaluated or processed data D to the vehicle user via an output unit 18.

[0030] As from Fig. 2, the illustrated dispensing device 20 according to the invention comprises a column 22 which can dispense the energy carrier E via an energy carrier transmission element 24.
