Description

The present invention relates to a charging system for supplying energy to at least one electric vehicle, the charging system having a charging station for this purpose. The invention also relates to a method for operating a charging system and a computer program for controlling the charging station.

It is known from the prior art that several public charging stations can be combined to form a common charging system in order to enable the charging stations to be controlled by a processing system. This simplifies the initiation of a charging process for a user who can do without initiation directly at the charging station. This improves convenience and flexibility for controlling the charging station. For example, the charging process can also be initiated when the user is further away from the charging station, e.g. B. out of sight of the charging station. However, it is a disadvantage that the possibilities for control via the processing system for a user are often still limited, e.g. B. limited to initiating and stopping the charging process. In addition, it can be a disadvantage that a visual control of the charging station by the user is not possible during the charging process, because the control is carried out by the user outside of the visual range of the charging station.

It is therefore an object of the present invention to at least partially remedy the disadvantages described above. In particular, it is the object of the present invention to propose an improved solution for operating a charging system.

The above object is achieved by a charging system with the features of claim 1, a method with the features of claim 9 and a computer program with the features of claim 15. Further features and details of the invention emerge from the respective subclaims, the description and the drawings. Features and details that are described in connection with the charging system according to the invention naturally also apply in connection with the method according to the invention and the computer program according to the invention, and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is or will always be made to each other can.

• - wenigstens eine (stationäre) Ladestation für eine Bereitstellung eines Ladevorgangs zur Energieversorgung für das Elektrofahrzeug,
• - wenigstens oder genau ein Verarbeitungssystem, welches eine Ansteuerungsschnittstelle zur Ansteuerung der Ladestation aufweist,
• - wenigstens ein Computerprogramm für ein mobiles Gerät, welches zur Ladesteuerung, insbesondere Initiierung und/oder Beendigung, des Ladevorgangs bei der Ladestation über die Ansteuerungsschnittstelle ausgeführt ist,
• - optional: eine Anzeigevorrichtung der Ladestation für eine Anzeige einer Energiemengeninformation über eine während des Ladevorgangs an das Elektrofahrzeug abgegebene Energiemenge,
• - optional: das mobile Gerät zur Ausführung des Computerprogramms.

The object is achieved in particular by an, in particular public, charging system for supplying energy to at least one electric vehicle, comprising:

• - At least one (stationary) charging station for providing a charging process for supplying energy to the electric vehicle,
• - at least or exactly one processing system which has a control interface for controlling the charging station,
• - At least one computer program for a mobile device, which is executed for charging control, in particular initiation and / or termination, of the charging process at the charging station via the control interface,
• - optional: a display device of the charging station for displaying information on the amount of energy relating to the amount of energy given to the electric vehicle during the charging process,
• - optional: the mobile device for executing the computer program.

In particular, it is provided that the computer program is designed to configure the charging station and / or the display via the control interface, preferably in addition to charging control, in particular initiating and / or terminating the charging process. The solution according to the invention thus has the advantage that the control provided for a user of the mobile device is not only reduced to control options with regard to the charging process, such as initiating or terminating the charging process, but is expanded to include a configuration of the charging station and, in particular, the display. This is particularly advantageous in view of the fact that, when the processing system is used, it is also possible for the user to control it outside of the range of sight of the charging station. For example, the processing system can be designed as a central processing system for several charging stations, and can also communicate with the mobile device in a network over longer distances. The invention is thus also based on the knowledge that a lack of visual inspection of the charging station for the user can be replaced by enabling the configuration. Advantageously, the configuration for this - as well as the charging control - can be carried out by the user out of sight of the charging station via the computer program. Technically, this can be made possible through the use of radio communication, through which a data connection is established between the control interface and the mobile device. The processing system can have the control interface and be provided outside the charging station. The radio communication can thus also be used to establish the data connection in the form of an Internet connection serve. Alternatively, the processing system can be part of the charging station, e.g. B. in the form of electronics of the charging station.

The provision of the energy supply can in particular serve to charge an energy store of the electric vehicle. The electric vehicle is preferably designed as an electric vehicle and / or hybrid vehicle, preferably as a passenger vehicle or truck. The electric vehicle can have an internal combustion engine as an additional drive, but alternatively can also be designed purely electrically.

The charging station can be designed as a stationary electrical charging device such as a charging column or the like, which is provided dedicated for charging electric vehicles. It can be a publicly (i.e. freely) accessible charging station, so that user control must be provided. This means that different users can use the charging station to charge an electric vehicle, provided that the respective user has been activated and / or authenticated at the charging station. For this purpose, it is advantageous if the processing system is used as a central processing system - in particular as a back-end - for several charging stations. The processing system can uniformly provide the control interface for the users so that the users can access it via the mobile device and the computer program in order to control the charging station. In addition, the central execution of the processing system enables several charging stations to be controlled centrally by the processing system. For example, user information and / or device information and / or default settings for the user can be stored centrally in the processing system and then used to initiate the charging processes of various charging stations. This use is z. B. for user authentication and / or for automatic configuration of the display. This has the advantage that a large number of charging stations and the users to control the charging stations can be managed centrally.

The charging station can have the display device for displaying the amount of energy information. In other words, the display device can be an integral part of the charging device; H. are physically at or in the charging station. Thus, the display device can be physically arranged at the charging station, and can be permanently and / or permanently connected to the charging station. Furthermore, there can be a permanent electrical connection between the display device and the further electrical system of the charging station.

The default setting for the configuration can advantageously first be defined by the computer program by the user, and then transferred to the processing system via the control interface and stored there, so that the computer program is designed in this way to configure the display via the control interface. This increases the convenience for the user and reduces the time required for configuration.

Linking this default setting with the user information and / or device information, optionally provided in the invention, can result in the default setting only being taken into account for configuration if the user is successfully authenticated on the basis of the user information and / or device information when the loading process is initiated. It can also be possible that when the display is configured later during the already initiated loading process, successful authentication is also required so that the configuration of the display can actually be carried out. The authentication can also be assumed for any further activation of the charging station by the computer program. This increases the safety when controlling the charging station considerably.

Furthermore, it is possible in a charging system according to the invention that the charging station has a charging interface such. B. has an electrical charging connection which is designed for wired and / or inductive energy transmission to the electric vehicle. The energy transfer can take place during the charging process in order to charge an electrical energy storage device such as a lithium-ion battery in the electric vehicle. In order to make the charging process controllable for a user, the display device on the charging station can be provided so that it is visible from the outside. Various information such as a meter reading of an energy meter of the charging station and / or the amount of energy information and / or the duration of the charging process and / or the activation state of the charging process and / or charging instructions and / or error messages and / or the like can be displayed on the display device. A configuration of this display usually takes place by the provider of the charging station and is therefore fixed. For this purpose, this configuration is permanently programmed into the charging station, for example when the charging station is manufactured. According to the invention it can be provided that the configuration takes place by the user via the computer program. This enables dynamic adaptation of the display so that the configuration and thus the selection of the information displayed can be changed for different charging processes. The computer program can be used for different users be provided, that is, several executions of the computer program can be operated at the same time. The configuration can be done in a decentralized manner, i.e. by the computer programs of various mobile devices at different locations. For this purpose, the computer programs can be in data connection with the processing system via the control interface.

Provision can be made for several charging stations to be combined to form a charging system, which are in data connection with a single processing system as a back-end. The charging stations can be controlled by the processing system via the data connections. The charging stations can also be controlled in a decentralized manner by mobile devices which can use a (single) control interface of the processing system for this purpose. The mobile device therefore does not have to connect directly to the charging station, but can use a single control interface of the processing system to control various charging stations by means of a computer program. This increases the flexibility and reliability of the control.

The amount of energy information can be implemented as value information of the amount of energy. The amount of energy can be determined using an electrical measuring device such as an energy meter. The energy meter is, for example, an electricity meter, i. H. an electrical measuring device that integrates over time to record the amount of electrical energy supplied by the charging station to charge the electric vehicle. The amount of energy information can include the conversion factor for the energy or work in order to display the amount of energy information in a specific unit such as watt-second or kilowatt-hour on the display device. The amount of energy information can be 0 at the beginning of the charging process and then increase as the charging process progresses. For this purpose, the amount of energy information can be determined from the initial count of the energy meter at the beginning of the charging process and the current count of the energy meter at a current point in time of the charging process, preferably by the difference between the current counter reading and the initial counter reading. The energy meter can also be calibrated, e.g. B. subject to legal calibration and / or carry a calibration mark. It can therefore also be provided that the counter readings are signed and / or have a signed time stamp. Thus, the initial counter reading can be the first signed counter reading, which after initiating the loading process, z. B. the user authentication exists. Correspondingly, a final counter reading can be the signed counter reading at the end of the charging process and, if necessary, can be displayed on the display device after the end. Furthermore, the energy meter can provide a communication protocol such as a “Smart Message Language” (SML) protocol in order to e.g. B. to transmit the amount of energy information to the display device and / or to configure the display. According to a further possibility, the display device can be part of the energy meter.

Preferably, within the scope of the invention, it can be provided that the charging station has an energy meter, which can be used to record and / or output and, in particular, display the amount of energy delivered to the electric vehicle during the charging process. Furthermore, the energy meter can be designed to display the recorded amount of energy via the amount of energy information on the display device. Alternatively or additionally, the computer program can be designed to transmit a control command via the control interface to the energy meter in order to initiate a switchover of the display from a deactivated state to an activated state and / or vice versa. This has the advantage that an expanded control option is provided for the user of the computer program, even and in particular when the user is not in sight of the charging station.

The control command can, for. B. in a first message format such as a "Hypertext Transfer Protocol" generated by the computer program and output to the control interface. The receipt of the control command in the first message format by the processing system via the control interface can have the effect that (e.g. by a data processing device of the processing system and / or in the charging station in response to the received control command) the control command in a second message format is sent to the energy meter is transmitted. For example, an SML message can be generated for this as a second message format, which is sent to the energy meter and triggers the switchover. This provides a reliable way of configuring the display by switching. In the deactivated state, the display can be at least partially deactivated, e.g. B. the display of the amount of energy information can be deactivated. In the activated state, the display can be at least partially activated, e.g. B. the display of the amount of energy information can be activated.

In the context of the invention, an activated display can be understood to mean that, in contrast to the deactivated display, the information (to be displayed) is visible and / or readable for a human observer on the display device.

Furthermore, it can be provided that the energy meter is designed to switch over the display during the charging process that has already been initiated when the transmitted control command is received (e.g. in SML format). In other words, the switchover can also take place when the charging process has been running for some time, and the amount of energy information therefore indicates an amount of energy greater than 0.

Advantageously, the invention can provide that the energy meter and / or the display device is designed to switch alternately between the display of the amount of energy information and further information, preferably information about a current meter reading of the energy meter, during the charging process. It can also be possible here for the energy meter and / or the display device to be designed to suppress the display of the amount of energy information as a function of the configuration by the computer program. This suppression can preferably also take place during the charging process, that is to say after the charging process has already started. For example, it may be possible to carry out the suppression initially at the beginning of the loading process, but also afterwards using the computer program via the configuration. This enables the user of the computer program a high degree of flexibility for configuring the display. The suppression can be initiated, for example, by transmitting a corresponding control command from the computer program and / or the mobile device to the control interface.

It is also conceivable that the display device is designed as an output and input device, for example as a touchscreen or the like. Thus, in addition to outputting the amount of energy information, the display device can also enable input information to be entered by a user. The input information can e.g. B. also serve to configure the display, specifically z. B. have the control command for suppression and / or configuration. This enables the charging station to be controlled directly at the charging station.

Furthermore, it can be provided within the scope of the invention that the computer program is designed to output a control command via the control interface to configure the display, the processing system having a data connection to the charging station in order to use the control command received by the processing system to open the charging station via the data connection to be controlled for configuration. The processing system can e.g. B. have a data processing device in order to forward the control command (possibly also changed, in a different message format and / or after further processing, e.g. checking and / or authentication) to the charging station. This has the advantage that there is no need for a direct connection between the mobile device and the charging station.

It is also optionally conceivable that the processing system is provided outside the charging station and, in addition to a data connection to the charging station, also has data connections to further charging stations with respective display devices for displaying the amount of energy information, in order to selectively, in particular based on a presetting and / or a control command, the Control charging stations to configure the respective display. The presetting can e.g. B. be stored in a non-volatile memory of the processing system in order to be able to use the same presettings for the initiation of the charging process and / or the configuration even with different charging stations. Several presets can be provided that are assigned to different users and / or mobile devices. This makes it possible to always be able to use the same pre-setting of the configuration for a specific user for a large number of loading processes without the user having to explicitly configure the configuration.

In a further possibility it can be provided that the processing system has at least one (electronic and / or central) data processing device, such as a server. By means of the data processing device, a control command and / or at least one additional device information about the mobile device and / or user information about a user of the mobile device can be received by the computer program via the control interface, processed and based on the processed control command and / or the device information and / or the user information can be used to configure the display. The control command and / or the device and / or user information can alternatively or additionally also be taken from a preset from a memory of the processing system in order to carry out the configuration of the display. This enables the display to be configured easily and conveniently.

• - ein Datennetzwerk,
• - ein Internet,
• - ein WLAN-Netzwerk (Wireless Local Area Network-Netzwerk),
• - ein Ad-hoc Netzwerk,
• - eine Nahfeldkommunikation, wie NFC (Near Field Communication) oder RFID (Radio Frequency Identification),
• - eine Funk-Kommunikation,

wobei vorzugsweise die Datenverbindungen unterschiedliche der Verbindungstechnologien aufweisen. Entsprechend kann die Ansteuerungsschnittstelle als eine elektronische Kommunikationsschnittstelle ausgeführt sein, welche die entsprechende Verbindungstechnologie bereitstellt. Wenn das Verarbeitungssystem (z. B. in der Form einer Elektronikanordnung) zumindest teilweise in die Ladestation integriert ist, kann eine Nahfeldkommunikation und/oder ein Ad-hoc Netzwerk und/oder ein WLAN-Netzwerk im Sichtbereich zur Ladestation eine technisch zuverlässige und kostengünstige Alternative zur Herstellung der Datenverbindung zwischen dem mobilen Gerät und der Ansteuerungsschnittstelle sein. Bspw. kann die Ansteuerungsschnittstelle in die Ladestation integriert sein, und somit die Datenverbindung zum weiteren Verarbeitungssystem herstellen, welches dann teilweise auch außerhalb der Ladestation vorgesehen sein kann. Das weitere Verarbeitungssystem außerhalb der Ladestation umfasst dann insbesondere eine Datenverarbeitungsvorrichtung wie einen zentralen Server, welcher mit mehreren weiteren Ladestationen verbunden sein kann. Damit wird der Vorteil erzielt, dass das mobile Gerät nicht direkt die Datenverbindung zur Datenverarbeitungsvorrichtung herstellen muss, sondern die Ansteuerungsschnittstelle der Ladestation hierzu nutzen kann. Alternativ hierzu kann die Ansteuerungsschnittstelle außerhalb der Ladestation vorgesehen sein, und das mobile Gerät direkt ohne Zwischenschaltung der Ladestation die Datenverbindung zur Ansteuerungsschnittstelle herstellen. Damit ist es möglich, dass die Konfiguration auch dann erfolgt, wenn sich das mobile Gerät außerhalb eines Sichtbereichs zur Ladestation befindet, z. B. mindestens 1 km entfernt.Preferably, within the scope of the invention, it can be provided that the control interface of the processing system has a data connection to the computer program, the data connection, and in particular a further data connection from the processing system to the charging station, having one of the following connection technologies:

• - a cellular network,
• - a data network,
• - an internet,
• - a WLAN network (Wireless Local Area Network),
• - an ad hoc network,
• - near field communication, such as NFC (Near Field Communication) or RFID (Radio Frequency Identification),
• - a radio communication,

wherein the data connections preferably have different connection technologies. Accordingly, the control interface can be designed as an electronic communication interface which provides the corresponding connection technology. If the processing system (e.g. in the form of an electronic arrangement) is at least partially integrated into the charging station, near-field communication and / or an ad-hoc network and / or a WLAN network in the field of view of the charging station can be a technically reliable and cost-effective alternative to establish the data connection between the mobile device and the control interface. For example, the control interface can be integrated into the charging station, and thus establish the data connection to the further processing system, which can then also be partially provided outside the charging station. The further processing system outside the charging station then comprises in particular a data processing device such as a central server, which can be connected to several further charging stations. This has the advantage that the mobile device does not have to establish the data connection to the data processing device directly, but can use the control interface of the charging station for this purpose. As an alternative to this, the control interface can be provided outside the charging station and the mobile device can establish the data connection to the control interface directly without interposing the charging station. This makes it possible for the configuration to take place even when the mobile device is out of sight of the charging station, e.g. B. at least 1 km away.

The invention also relates to a method for operating a charging system, in particular a charging system according to the invention, preferably for controlling a charging station of the charging system.

• - Bereitstellen eines Ladevorgangs durch die Ladestation für eine Energieversorgung wenigstens eines Elektrofahrzeugs,
• - Bereitstellen einer Ansteuerungsschnittstelle eines Verarbeitungssystems zur Ansteuerung der Ladestation,
• - Durchführen einer Ladesteuerung wie eine Initiierung und/oder Beendigung des Ladevorgangs bei der Ladestation durch ein Computerprogramm für ein mobiles Gerät, insbesondere durch eine Benutzereingabe bei dem mobilen Gerät, wobei das Computerprogramm die Ladesteuerung (insbesondere Initiierung) über die Ansteuerungsschnittstelle durchführen kann, z. B. durch eine Datenübertragung eines Steuerbefehls,
• - optional: Bereitstellen einer Anzeige einer Energiemengeninformation über eine während des Ladevorgangs an das Elektrofahrzeug abgegebene Energiemenge durch eine Anzeigevorrichtung der Ladestation,
• - Durchführen einer Konfiguration der Ladestation und/oder der Anzeige durch das Computerprogramm über die Ansteuerungsschnittstelle, insbesondere durch die Datenübertragung eines Steuerbefehls.

Damit bringt das erfindungsgemäße Verfahren die gleichen Vorteile mit sich, wie sie ausführlich mit Bezug auf ein erfindungsgemäßes Ladesystem beschrieben worden sind. Zudem kann vorgesehen sein, dass die Ladestation und/oder das Verarbeitungssystem und/oder das Computerprogramm des mobilen Geräts und/oder das mobile Gerät Teile eines erfindungsgemäßen Ladesystems sind.It is provided that the following steps are carried out, preferably one after the other or in any order:

• - Provision of a charging process by the charging station for an energy supply of at least one electric vehicle,
• - Provision of a control interface of a processing system for controlling the charging station,
• - Carrying out a charging control such as an initiation and / or termination of the charging process at the charging station by a computer program for a mobile device, in particular by a user input on the mobile device, wherein the computer program can carry out the charging control (in particular initiation) via the control interface, e.g. B. by a data transmission of a control command,
• - optional: providing a display of an amount of energy information about an amount of energy delivered to the electric vehicle during the charging process by a display device of the charging station,
• - Carrying out a configuration of the charging station and / or the display by the computer program via the control interface, in particular by the data transmission of a control command.

The method according to the invention thus brings the same advantages as have been described in detail with reference to a charging system according to the invention. In addition, it can be provided that the charging station and / or the processing system and / or the computer program of the mobile device and / or the mobile device are parts of a charging system according to the invention.

• - Aktivieren der Anzeige, um ein Ablesen der Energiemengeninformation während des Ladevorgangs zu ermöglichen,
• - Deaktivieren der Anzeige, um das Ablesen der Energiemengeninformation während des Ladevorgangs zu verhindern,
• - Aktivieren eines alternierenden Anzeigemodus, bei welchem zwischen der Anzeige der Energiemengeninformation und einer weiteren Information, vorzugsweise einer Information über einen aktuellen Zählerstand eines Energiezählers der Ladestation, umgeschaltet wird,
• - Deaktivieren des alternierenden Anzeigemodus,
• - Aktivieren eines geschützten Anzeigemodus, bei welchem die Anzeige deaktiviert ist, und in Abhängigkeit von einer Authentifizierung eines Benutzers des mobilen Geräts an der Ladestation aktiviert wird, bevorzugt nur bei erfolgreicher Authentifizierung die Anzeige zu aktivieren.

Die Konfiguration, insbesondere die initiale Einstellung und/oder eine Umschaltung zwischen einer dieser Einstellungen während des laufenden Ladevorgangs, kann dabei ferngesteuert durch das mobile Gerät bzw. das Computerprogramm durchgeführt werden. Somit ist eine komfortable und flexible Nutzung der Ladestation durch einen Benutzer möglich. Es kann möglich sein, dass es sich bei dem Benutzer um einen Fahrer und/oder Nutzer des Elektrofahrzeuges handelt, welcher die Ladestation zum Aufladen nutzt. Entsprechend kann der Benutzer nicht als Wartungspersonal oder dergleichen verstanden werden, welches eine grundsätzliche Konfiguration der Ladestation für Ladevorgänge unterschiedlicher Benutzer durchführt. Die Konfiguration kann somit auch als eine Benutzerkonfiguration verstanden werden, welche benutzerspezifisch ist.Another advantage is that when the display is configured, at least one of the following settings is made:

• - Activation of the display to enable reading of the amount of energy information during the charging process,
• - Deactivating the display to prevent the reading of the amount of energy information during the charging process,
• - Activation of an alternating display mode, in which a switch is made between the display of the amount of energy information and further information, preferably information about a current meter reading of an energy meter in the charging station,
• - Deactivating the alternating display mode,
• - Activate a protected display mode in which the display is deactivated, and in Is activated depending on an authentication of a user of the mobile device at the charging station, preferably only to activate the display if the authentication is successful.

The configuration, in particular the initial setting and / or switching between one of these settings while the charging process is in progress, can be carried out remotely by the mobile device or the computer program. This enables convenient and flexible use of the charging station by a user. It can be possible that the user is a driver and / or user of the electric vehicle who uses the charging station for charging. Accordingly, the user cannot be understood as maintenance personnel or the like who carry out a basic configuration of the charging station for charging processes of different users. The configuration can thus also be understood as a user configuration which is user-specific.

It can optionally be possible for the configuration to be carried out together with an authentication of a user of the mobile device when the charging process is initiated. The configuration can thus be carried out automatically at the start of the loading process and only if the authentication is successful and in particular if the user has sufficient authorization. This increases the safety when operating the charging system.

In addition, it is advantageous if the configuration is carried out on the basis of a preset which is read out by the mobile device and / or a data processing device of the processing system, preferably from a non-volatile memory, so that the configuration is preset for different charging processes - in particular for the same user - can be carried out. The default setting can be stored centrally in the processing system in a non-volatile manner in addition to other default settings for other users. This offers a technically easy-to-manage option for user-specific configuration of the charging stations that are in data connection with the processing system.

In addition, it is conceivable within the scope of the invention that the processing system has a central data processing device which has a data connection to the charging station and further charging stations in order to selectively control at least one of the following functions at the charging stations:

• - the configuration, especially the display,
• - initiating and / or terminating the charging process,

It is provided that the configuration takes place via the control interface.
