Abstract

The invention relates to a method for carrying out a charging process of an electrically driven vehicle by means of a charging cable. The invention also relates to an electrically drivable vehicle and a charging cable for carrying out the method. The method is characterized by the following method steps and case distinctions: Existing motor vehicle and / or infrastructure plug connections between charging plugs and charging sockets are locked at the beginning of the charging process (method step S2). Then it is queried in a query (A1) whether the charging cable is an integral part of the vehicle or not. If yes, the termination of the charging of the infrastructure-side connector (step S3.2) takes place at the end of the charging process, which is determined in a query (A3.2). If the charging cable is not an integral part of the vehicle, then a Query (A2) queried whether it is a separate or foreign charging cable. In the case of a foreign charging cable after completion of the charging process (query A3.1), the locking of the vehicle-side connector removed (step S3.1) .Due to this method, a smoother charging of a plurality of vehicles to be charged at charging stations of a charging station is possible.

Description

The invention relates to a method for carrying out a charging process of an electrically driven vehicle having the features of the preamble of patent claim 1. The invention also relates to an electrically drivable vehicle and a charging cable for carrying out the method.

Many vehicle manufacturers have taken up the cause to significantly expand electromobility. It is therefore to be expected that the number of electric vehicles in road traffic will increase significantly.

A challenge for car manufacturers is not only to provide electric vehicles that are comparable in performance and range with the conventionally operated vehicles, but also to create suitable conditions that the expected large number of electric vehicles in the near future easily charged can be.

To secure a charging process and also for theft protection, it has hitherto been customary to lock the charging cable to the vehicle (motor vehicle side) and / or to the charging station (on the infrastructure side) during the charging process. The lock causes the charging cable during the charging process can not be solved by the vehicle and / or the charging station and a release first takes place when the leader of the vehicle to be charged (again) is in the vicinity and issued an enable signal. This can be done for example by pressing the central locking via the remote key.

However, such an approach has the disadvantage that existing charging stations are unnecessarily blocked. In other words, it may happen that the locking of a charging cable vehicle and / or infrastructure side is maintained well beyond the actual duration of a charging out when the driver is not present and, for example, go shopping.

Occasionally, this problem is solved by the fact that in the area of charging stations of a charging station authorized parking space controllers check charging processes and perform a manual unlocking after completion of a charging process.

From the DE 10 2012 013 865 A1 a method having the features of the preamble of claim 1 is known. Specifically, the use of an intelligent charging cable to map car sharing processes is proposed. The integrated electronics in the charging cable allow the intelligent charging cable to interact with the vehicle and the charging infrastructure. Interaction can be used to prevent the locking of the charging cable required by the standard in the vehicle and in the charging station from being released again and the cable to be removed from the vehicle or the charging station. In this way, the vehicle can be permanently immobilized. The unlocking and thus the charging cable is only possible after a successful authentication of a car sharing customer.

In which also the features of the preamble of claim 1 having DE 10 2009 030 092 A1 a charging cable connector for electric vehicles is described, in which a transponder reading device for reading a transponder transmission field is integrated. The transponder transmission field can be generated by a radio key of a user. The transponder reading device is in signal communication with an identification means which can transmit an identification signal via contacts of the charging cable plug to a charging station. The housing of the charging cable connector also has grooves in the locking pins of the charging station for locking purposes are retractable. To allow an authorized user to deduct the charging cable after completion of a charge from the charging station again, the charging station an existing authorization of the user is signaled by the sent from the charging cable connector identification signal. However, this presupposes that the authorized user with his radio key (after a recharge again) in the immediate vicinity of the charging station.

Finally, in the DE 10 2010 014 417 A1 Also presented is an intelligent charging cable for electric vehicles, which is equipped with an integrated logic for monitoring, controlling and charging a charging process. This should create independence from the vehicle manufacturer and the charging infrastructure provider. Among other things, it is proposed that the integrated logic provide a graphical user interface for outputting state of charge information and for authenticating a user.

Against this prior art, the present invention based on the object to provide a method for performing a charging operation of an electrically driven vehicle, in a simple manner and cost unnecessary blocking of charging stations can be prevented, even if a leader of the vehicle is not present is.

Another object of the invention is to provide a suitable electrically powered vehicle and to provide a suitable charging cable for carrying out the method according to the invention.

The above objects are achieved by a method having the features of claim 1, an electrically driven vehicle having the features of claim 8 and a charging cable having the features of claim 12. Advantageous embodiments or developments can be found in the respective dependent claims.

The invention is based on a method for carrying out a charging process of an electrically driven vehicle. To carry out the charging process, an electrical connection between the vehicle and an infrastructure-side charging station is established via a charging cable. Vehicle side, the electrical connection is made by a vehicle-side connector element and a cable-side connector element having connector. Alternatively or additionally, on the infrastructure side, an electrical connection can take place through a plug-in connection having an infrastructure-side connector element and a cable-side connector element.

The said connector elements may be formed in a suitable manner as a plug or socket.

The electrically drivable vehicle may be, for example, a pure electric vehicle or even a hybrid vehicle. It is also conceivable to use the method according to the invention in electrically operated two-wheeled vehicles.

1. a) Es wird ein loses Ladekabel eingesetzt, welches sowohl mit der Ladesäule als auch mit dem Fahrzeug elektrisch verbunden werden muss
2. b) Das Ladekabel ist integraler Bestandteil der Ladesäule und muss lediglich mit dem Fahrzeug verbunden werden
3. c) Das Ladekabel ist integraler Bestandteil des Fahrzeugs und muss lediglich mit der Ladesäule verbunden werden (eher selten)

When carrying out recharging processes, the following case constellation is conceivable:

1. a) A loose charging cable is used, which must be electrically connected both to the charging station and to the vehicle
2. b) The charging cable is an integral part of the charging station and only has to be connected to the vehicle
3. c) The charging cable is an integral part of the vehicle and only needs to be connected to the charging station (rather rare)

• • Falls das Ladekabel nicht über eine Steckverbindung mit dem Fahrzeug verbunden ist, sondern integraler Bestandteil des Fahrzeugs ist, so erfolgt eine Kennzeichnung, dass es sich um ein eigenes Ladekabel handelt. Die Kennzeichnung kann beispielsweise durch ein in einem Speicher des Fahrzeugs abgelegtes Zustandsbit erfolgen. Diese kann abgefragt werden und signalisieren, dass das Fahrzeug über ein eigenes, integrales Ladekabel verfügt.
• • Falls das Ladekabel über eine Steckverbindung mit dem Fahrzeug verbunden ist, erfolgt zunächst eine Prüfung, ob es sich um ein fremdes oder eigenes Ladekabel handelt. Als „fremd“ wird ein solches Ladekabel eingestuft, welches nicht dem aufzuladenden Fahrzeug und/oder nicht der den Ladevorgang durchführenden, autorisierten Person sondern der Ladeinfrastruktur (Ladestation bzw. Ladesäule) zuordenbar ist. Entsprechend umgekehrte Kriterien weist ein als „eigen“ eingestuftes Ladekabel auf. Die Einstufung als „fremd“ oder „eigen“ kann durch Abfrage bestimmter bzw. zu bestimmender geometrischer oder grafischer Merkmale und/oder Daten erfolgen.

The method according to the invention is therefore characterized by the following method steps and case distinctions:

• • If the charging cable is not connected to the vehicle via a plug-in connection, but is an integral part of the vehicle, it will be indicated that it is a separate charging cable. The identification can be carried out, for example, by a status bit stored in a memory of the vehicle. This can be queried and signal that the vehicle has its own, integral charging cable.
• • If the charging cable is connected to the vehicle via a plug connection, a check is first made as to whether it is a separate or separate charging cable. Such a charging cable is classified as "foreign", which can not be assigned to the vehicle to be charged and / or to the authorized person carrying out the charging process, but rather to the charging infrastructure (charging station or charging station). According to the opposite criteria has a classified as "own" charging cable. The classification as "foreign" or "own" can be done by interrogating certain or to be determined geometric or graphical features and / or data.

If it is now a foreign charging cable, an existing locking of a vehicle-side connector is canceled after completion of the charging process. The release of the locking is preferably carried out promptly after completion of the charging process, more preferably within a few seconds.

In this way it can be ensured that after completion of a charging a foreign charging cable by a third party who wants to charge another vehicle, released from the charged vehicle again and thus can be used. Blocking the required charging cable is thus effectively prevented.

In the case of a separate charging cable, on the other hand, an existing locking of an infrastructure-side plug-in connection is canceled after the charging process has ended. Also in this case, the release of the lock is preferably timely, more preferably within a few seconds.

As a result, a required connector element of a charging station, that is to say an infrastructure-side connector element, can be quickly used again by a third party after completion of a charging process.

The said connector elements complement each other vehicle and infrastructure side to a connector and thus can be designed as a plug or socket with a corresponding connector element on the "opposite side".

In one embodiment of the method, it is proposed that in the case of a separate charging cable, an existing locking of a vehicle-side connector be maintained until a separate release request is made by an authorized person. Such a release request can be made for example by unlocking the central locking via a remote key or another command. Thus, despite the suspension of the blocking of an infrastructure-side connector element, a charging cable is kept theft-proof on one's own vehicle.

According to a development of the method, the check is made as to whether it is a separate or foreign charging cable via a vehicle-side identification of the cable-side connector element (eg charging plug) located in the vehicle-side connector element (eg charging socket).

Such a configuration makes it easy to identify the charging cable without the charging cable itself having to be connected to or having a power supply.

In a further embodiment of the inventive concept, it is therefore conceivable that the test takes place via an in-vehicle transceiver unit. This unit can be designed, for example, as an RFID reading unit (RFID = Radio Frequency Identification).

Alternatively, it is also conceivable that the test takes place via a sensor on the vehicle side. The sensor may be configured to be capable of detecting geometric features of the cable-side connector element. For example, he can work tactile or capacitive.

According to another embodiment, a vehicle-side alarm signal is triggered when a tampering of the charging cable and / or the vehicle or infrastructure-side connector is detected during the charging process. A manipulation can for example be given by the attempt to solve one of the connectors by force. Even a multiply detected movement of the charging cable within a short period of a few seconds or minutes can be interpreted as manipulation.

Through this development, a certain protection against unauthorized manipulation during a charging process can be given.

It should be noted separately that a charging process does not necessarily have to include a complete charge of the vehicle. Rather, it is at the driver's discretion to self-determine the amount of charge desired (e.g., full charge, or only a percentage). For easy implementation of the method according to the invention, it is then conceivable that the charging station is notified of termination of the charging process by a vehicle-side signal. After receiving such a signal, the charging station can then cancel an existing locking of the infrastructure-side connector.

As already mentioned, the invention also relates to an electrically drivable vehicle with which the method according to the invention can be carried out. The vehicle is equipped with a vehicle-side connector element for electrical charging, which may be formed for example as a charging socket.

According to the invention, it is now proposed that the vehicle has at least one identifying means for identifying a cable-side connector element connected to the vehicle-side connector element and belonging to a separate or external charging cable. In this way, it is possible to design charging cables themselves cost-effective, since it can be dispensed with complex electronics in the charging cable with its own power supply.

It is very expedient in this case if the at least one identification means is designed as a transmission / reception unit arranged in the vehicle-side connector element or in its immediate vicinity. The transmitting / receiving unit can be, for example, an RFID reader which emits a high-frequency reading field, by which the identification of a transponder can be read, which is located in the cable-side connector element.

Alternatively or as a redundant solution, it is conceivable that the at least one identification means is configured as a sensor arranged in the vehicle-side connector element, by which certain geometric or graphic features of a cable-side connector element connected to the vehicle-side connector element can be recognized. Certain geometric features can be given for example by recesses and / or projections. It is also conceivable to generate certain graphic features by symbols, characters, codes or the like. These may also be part of a sticker applied to the cable-side connector element.

According to another embodiment of the electrically drivable vehicle is located in this transmission unit, via the charging station, a termination of the charging process can be transmitted. The transmitting unit is preferably designed as a PLC transmitting unit. Due to the design as a PLC transmission unit (PLC = Power Line Communication), existing electrical lines can be used to set up a local network for data transmission. Thus, no additional wiring is necessary and a communication can be very cost-effective, for example. About the charging cable used to be performed.

Finally, the invention also relates to a charging cable for carrying out the method. The charging cable has at least one connector element (if it is an integral part of a charging station or a vehicle).

According to the invention, the at least one connector element is provided with an identification such that it can be distinguished whether the charging cable is a separate or a foreign charging cable in the sense of the invention.

Cost-effective and reliable, this can be realized if in the at least one connector element, a radio-based communication unit is arranged, from which an identification is read out. The radio-based communication unit is preferably designed as an RFID transponder (RFID = Radio Frequency Identification). An RFID transponder does not require its own power supply and its identification can be easily and reliably read by a suitable RFID reader.

Alternatively or additionally, it is also conceivable that the at least one connector element corresponds to a specific standard and -if it should be classified as a separate charging cable in the context of the invention- beyond at least one additional, geometric and / or graphical feature.

The cable-side connector element will initially have all the features that dictates a common standard. For example, the standard ISO / IEC 61851 is currently the most widespread in Europe. In addition to the features specified by this standard, the connector element may have, for example, a pin-like projection or a groove-like notch as an additional, geometric and / or graphic feature. Also, the application of a reflective sticker, the reflection of which can be detected by a light-receiving sensor, is conceivable. Furthermore, the use of a sticker with certain codes (eg bar code or QR code) is conceivable.

Preferred embodiments of the invention are illustrated in the figures and will be explained in more detail with reference to the figures in the following description. As a result, even further advantages of the invention become apparent. The same reference numerals, even in different figures, refer to the same, comparable or functionally identical components. In this case, corresponding or comparable properties and advantages are achieved, even if a repeated description or reference does not occur.

First, it will open 1 Referenced. This shows a possible, preferred sequence of the method according to the invention.

Thus, after establishing an electrical connection between the vehicle to be charged and the charging station by a suitable charging cable, the charging process in one process step S1 started. The driver initiating the charging process can determine to what extent charging is to take place. For example, he may initiate a full charge, or even specify a percentage of it to speed up the charging process, for example. In one process step S2 there is a locking of existing connectors, the method steps S1 and S2 can also merge into each other. If present, both a vehicle-side and an infrastructure-side connector are locked so that they can not be solved.

In a query A1 is queried by a suitable control logic, whether the used charging cable is an integral part of the aufzuladenden vehicle or not. As an integral part of the vehicle, a charging cable should be designated when it is insoluble, at least not detachable without tools, is connected to the vehicle. Information about this can be stored for example by a queryable status bit in a memory module of the vehicle electronics.

If the charging cable is an integral part of the vehicle, so after completion of the charging process in one step S3.2 unlocked the infrastructure-side connector. Thus, an infrastructure-side connector can be separated if necessary by a third party by removing the charging cable. The infrastructure-side connector element is thus available for charging another vehicle again. The query as to whether a loading process has ended is made in a query A3.2 , which is repeated cyclically.

Was in the query A1 determined that the charging cable is not an integral part of the vehicle, it is carried out as part of a query A2 a check whether it is a separate or external charging cable. How the test can be done in detail will be described in more detail later.

As "foreign" within the meaning of the invention, such a charging cable is to be understood, which is provided on the infrastructure side, that is, for example, an integral part of a charging station or which is provided by a charging station (with possibly several charging stations) for charging freely available.

If the check in the query A2 shows that it is a separate cable, so after completion of the charging process also in the process step S3.2 only the interlocking of the infrastructure-side plug connection is canceled.

However, if it is a foreign cable, so after completion of the charging process, which is queried analogously to query 3.2 in a query 3.1, a locking of the vehicle-side connector in a step S3.1 canceled. In this way, it becomes possible for a third party to pull the charging cable out of the charged vehicle and use it to charge its own vehicle.

With the process step S4 the end of the procedure should be quantified.

Optionally it is suggested that in a query aopt or Aopt 'can be queried whether a manipulation of the charging cable and / or an existing connector is performed during the charging process. If this is determined, it is conceivable to have an optical and / or acoustic alarm signal output by the vehicle in an optional method step Sopt and to completely abort the charging process without unlocking the plug-in connections. Additionally or alternatively, in case of manipulation, a message can also be sent to a mobile device to be determined.

It seems very convenient if, after a scheduled completion of a charge from the charged vehicle, a message to the charging station. At the charging station can then be displayed on a suitable display device that the charging process is completed and a required connector element or a charging cable are available again. Likewise, an ongoing charge should be displayed. This can prevent that a charging cable is mistakenly manipulated during a charging process and possibly an unfounded alarm signal is triggered.

In 2 is now a charge of a vehicle designed as an electric vehicle K1 shown. The vehicle K1 is via a charging cable L1 at a charging station LS1 electrically connected. The charging station LS1 may be one of several charging stations of a charging station, not shown, similar to a conventional gas station. The electrical connection of the charging cable L1 is via a motor vehicle-side connector sk and an infrastructure-side connector Sinf realized. The motor vehicle-side connector sk consists of a vehicle-side connector element 3 in the form of a charging socket and a cable-side connector element 4 in the form of a charging plug. The infrastructure-side connector Sinf is provided by an infrastructure-side connector element 1 in the form of a charging socket and by a cable-side connector element 2 formed in the form of a charging plug.

In the vehicle K1 is also a vehicle-side transmitting unit 6 available. Furthermore, in a vehicle-side, electronic memory module 14 a queryable status bit stored, on the basis of which it can be determined whether the charging cable L1 integral part of the vehicle K1 is or not. In the embodiment, the charging cable L1 not an integral part of the vehicle K1 and thus the status bit in the memory module 14 is set to "0".

Further, in the charging station LS1 an infrastructure-side receiving unit 5 present, with the on-board transmitter unit 6 can communicate. The transmitting unit 6 is preferably designed as a so-called PLC transmission unit. The PLC (Power Line Communication) technology is a wired transmission of signals through the low voltage cables of the charging cable L1 or the electrical contacts and lines involved in the electrical connection possible. So can over the transmitting unit 6 a status signal to the receiving unit 5 transmitted, which gives information about the existence or the end of a charging process.

In the 3 are the infrastructure-side and the motor vehicle side connector Sinf and sk shown to the extent necessary for the understanding of the invention.

Thus, it can be seen that the cable-side connector element 2 radially outwardly directed, groove-like depressions 20 has, in the locking pins 10 can retract radially to a locking position (see 10 ').

The locking pins 10 be via a drive device 8th moves, wherein the drive means 8th via an evaluation and control device 7 is controlled.

Once the receiving unit 5 from the transmitting unit 6 has received a signal that a charging process was properly initiated receives the evaluation and control device 7 a corresponding signal for controlling the drive device 8th , This causes a movement of the locking pins 10 in the locking position.

On the side of the motor vehicle side connector sk are in the connector element 3 also locking pins 30 by means of a drive device 33 in groove-like recesses 40 of the connector element 4 radially movable (compare 30 '), so that a locking position is achieved.

The drive device 33 is via an evaluation and control device 32 driven.

Furthermore, it can be seen that in the connector element 3 a transmitting / receiving unit 31 is available. The send / receive unit 31 is preferably designed as an RFID reader (RFID = Radio Frequency Identification). The send / receive unit 31 can thus generate a transmission field, which is designed as an RFID transponder transmitting unit 41 activate and thus one in the transmitting unit 41 stored identification of the connector element 4 can read.

With SL are tax and data lines quantified by which the components mentioned are interconnected.

About the send / receive unit 31 So can the identity of the connector element 4 be determined. In other words, by reading one in the transmitting unit 41 deposited identification, whether it is a separate or external charging cable L1 is.

If through the transmitting unit 6 a termination of the charging process is signaled, so are in an identification of the charging cable L1 as foreign the drive devices 8th and 33 driven such that the locking pins 30 from the wells 40 drive out and thus the locking of the motor vehicle side connectors sk release. The locking pins 10 however, remain in the wells 20 , Thus, the lock of the infrastructure-side connector Sinf maintained.

In the event that the charging cable L1 is identified as own, there is a control of the drive means 8th and 33 or a movement of the locking pins 10 and 30 exactly in the opposite way. In this case, so the locking of the infrastructure-side connector Sinf solved and that of the motor vehicle side connector sk remains.

In the 4 is an alternative embodiment of a motor vehicle side connector element 11 shown. In contrast to the connector element 3 is the connector element 11 with a sensor 111 for detecting an example button-like Anformung 120 fitted. The formation 120 is to a cable-side connector element 12 molded and serves as identification of the connector element 12 in such a way that it can be seen that the connector element 12 belongs to a separate charging cable.

The sensor 111 is preferably designed as a capacitive proximity sensor, which in the presence of Anformung 120 a signal to an evaluation and control device 112 emits.

Instead of molding 120 is also conceivable, a recess 121 to provide in the connector element 12. The formation 120 or the recess 121 should the connector element 12 identify as belonging to a separate charging cable. The formation 120 or recess 121 represent certain geometric features of the connector element 12 which differ slightly from a given standard, for example the ISO / IEC 61851 standard.

The thus identified as belonging to its own charging cable connector element 12 is not released after completion of a charge, but an existing lock a motor vehicle side connector Sk 'is maintained. Also in this embodiment, a lock is formed by radially in groove-like depressions 122 of the connector element 12 radially retractable locking pins 110 accomplished (compare also 110 '). The drive of the locking pins 110 via a drive device 113 ,

Out 5 it can be seen that a charging station LS2 also a charging cable L2 may have, which insoluble with the charging station LS2 connected, so integral part of the charging station LS2 is. Consequently, the status bit in the memory module is also 14 also set to "0". In the illustrated embodiment, the charging cable L2 via a roll-up mechanism 9 rolled up or extendable in the charging station LS2 held. The already known vehicle K1 can turn on the motor vehicle side connector sk electrically with the charging station LS2 get connected. At the end of the charging takes place in this case a release of the vehicle-side connector Sk.

Finally, in the 6 the one case presented in which an electrically powered vehicle K2 with a charging cable L3 equipped, which is an integral part of the vehicle K2 is. Specifically, the charging cable L3 via a motor vehicle-side retracting mechanism 13 rolled up or extendable in the vehicle K2 held. An electrical connection of the charging cable L3 with the charging station LS1 again takes place via an infrastructure-side connector Sinf , Because the vehicle K2 in this case via a charging cable L3 which is an integral part of the vehicle K2 is, was the in-vehicle memory chip 14 with a status bit (= "1") occupied, which is readable in the case of charging and the charging cable L3 as own charging cable.
