Description

The invention relates to a method for operating a charging station having at least one charging point for an electrically operable vehicle with the following working steps: connecting the vehicle to a charging point of the charging station via a charging cable; Checking a charging authorization for the vehicle and / or a user by comparing a charge identifier assigned to the vehicle and / or the user and made available via an input means of the charging station with at least one register identifier stored in a charge register assigned to the charging point of the charging station; Providing energy to the vehicle at the charging point if the charging identifier associated with the vehicle and / or the user matches at least one register identifier; wherein the at least one stored in the load register register identifier for the charging point is set and / or changed and / or deleted. Furthermore, the invention relates to a charging station for carrying out the invention.

Generic operating methods for charging stations for electrically operable vehicles are becoming increasingly widespread. The check of the charging identification of the vehicle or of the user is carried out in this case in order to be able to charge the costs of the charging operation to the vehicle owner or user or to be able to infer the intensity of use of the vehicle on the basis of the frequency and duration of the charging operations. If the intensity of use of the vehicle is known, for example, improper use can be prevented or an expected maintenance time for the vehicle can be determined. The latter parameters are of particular interest to corporate vehicle fleets. In addition, the assignment of the vehicles to a charging point has the advantage that the load at the charging point is known and can be controlled.

Usually, the administration of user rights is carried out centrally within a public or on a company premises installed partial public charging infrastructure with a variety of charging points, by the various users or vehicles are registered in a common database. For identification of a vehicle or a user, a charging identifier is usually provided, which in many cases is provided electronically via an RFID chip. With the charging identifier, you can then perform a charging process at any charging point within the provided charging infrastructure. For this purpose, the charging identifier is read in via an input means, for example an RFID reader, and compared with the vehicle or user accesses (register identifier) stored in the central database.

In order to have better control over the various charging processes, it can be provided that exactly one predetermined charging point is assigned to each vehicle and / or each user within the charging infrastructure. The vehicle is then parked to carry out the charging on a charge point associated parking and connected to the charging station. A legitimation for the charging process (charging authorization) is carried out as usual via a unique charging identifier. This charging identifier can for example be realized electronically or by means of a mechanical key switch. For example, when providing a key switch as an input means for the charging identifier at the charging station in the vehicle authorized to use the charging station a key carried, so that any driver (user) can perform the charging process for this vehicle at the one, associated charging point.

For corporate vehicle fleets, providing a higher-level user administration for the sometimes very large charging infrastructure is expensive. In contrast, the use of mechanical key switches in practice has proven itself. The disadvantage here, however, the large logistical effort, which occurs in particular for the initial assignment of the charging permissions and / or changing the assignment of a charging authorization to a charging point or the loss of a key. Furthermore, the replacement keys must be managed.

The object of the present invention is therefore to simplify an operating method for a charging station and, in particular, to specify a method which simplifies the allocation of charging authorizations for a single vehicle or individual users at a predetermined charging point.

To achieve the object, the method according to the invention in conjunction with the preamble of claim 1, characterized in that access to a charging point associated, initially limited access provided at the charging station actuator is released; then actuating the actuator to place the loading station in a register initialization mode; Then, in the register initialization mode, a charge identifier is read in via the input means provided on the charging station and stored as a register identifier in the charge register of the charging point.

The particular advantage of the invention is that a loading authorization for a by a plug-in element of the charging station defined charge point can be set or changed for the first time in a very simple manner. For this purpose, an access is initially provided to the actuating element preferably provided inside the charging station behind a door or flap secured by a lock. This is done in particular by an administrator who has a key for the lock. Subsequently, the loading station is set by the actuation of the actuating element in a register initialization mode. Via the input means provided anyway at the charging station, a charging identifier is then read in and stored as a register identifier in the loading register. By using the input means provided anyway for reading in the charge identifier, the costs of a charging station provided for carrying out the method according to the invention are reduced. On separate input means and in particular a mechanical key switch can be waived insofar. After the load identifier is stored as a register identifier in the load register, the register initialization mode can be terminated. This is done, for example, time-controlled or automatically after reading a load identifier. It can also be provided that the register initialization mode is ended by actuating the actuating element again. Furthermore, the access restriction for the actuating element is restored and the charging station is used in the usual operating method for carrying out charging operations.

For example, the secured door with the lock or door of the charging station can be provided at the same time to realize the maintenance access to the charging station. The administrator is then maintenance manager or authorized person for the charging stations.

According to a development of the invention, the register initialization mode can be aborted automatically after a predefined initialization time interval if no charge identifier is entered after the actuation of the actuation element within the initialization time interval. Advantageously, this prevents a faulty operation or an improper cancellation of a registration process. It is ensured that the charging station in a non-completed registration process in the normal operating state is reset.

According to a development of the invention can be provided that upon actuation of the actuating element, the charging station enters the Registerinitialisierungsmodus and that the Registerinitialisierungsmodus is terminated as soon as the actuation of the actuating element is interrupted. For example, as an actuating element, a push-button or a pressure switch can be provided.

According to a development of the invention, the read in via the input means charging identifier is stored at a defined memory location within a memory of the load register. The storage space is determined in particular via a storage routine, which preferably takes place in a control unit of the charging station. For example, the memory of the load register can be dimensioned so that only a single load identifier is always stored in the load register. This ensures that a single charging point of the charging station can always be used only by a single user or for a single vehicle. This gives you the maximum control over the charging point and the charging process. For example, the memory of the load register may be larger. In particular, a plurality of register identifiers may be provided simultaneously in the load register. In this case, provision may be made for a memory data or a pointer value correlated to a memory sequence of the plurality of register identifiers to be stored together with the register identifier. Advantageously, by providing a larger memory and storing a plurality of register identifications, the charging point of the charging station can be variably made available to a plurality of users or to different vehicles. This results in greater flexibility with regard to the use of the charging infrastructure.

According to a development of the invention, a newly read in charge identifier is stored in a free memory space within the memory of the load register, unless the memory of the load register is completely described. If the memory of the load register is completely described or because of the dimensioning of the memory, only a single load identifier can be stored as a register identifier in the memory of the load register, the single or a longest stored register identifier is overwritten with the new load identifier. The longest stored register identifier is identified by the memory data or the pointer value correlated to the memory order of the register identifier.

According to a development of the invention, a plurality of charging points can be provided at the charging station, wherein a separate actuating element and a separate charge register are provided for each charging point. For example, a separate input means can be provided for each charging point. In this case, after the actuation of the charging element associated with the charging element, a charging identifier is read in via the input means assigned to the charging point, and in the load register, which is assigned to the charging point, stored. For example, a common input means may be provided for a plurality of charging points. The charging point associated with the actuating element and the charging register assigned to this charging point are then identified or selected on actuation of an actuating element. A load identifier read in via the common input means is then stored as a register identifier in the load register of the selected load point.

If a common input means is provided, a charge identifier read in via the common input means is compared with register identifiers stored in the various load registers during the normal operating state for checking the charge authorization. Energy is then provided for each charging point for which the charge identifier read in via the common input means coincides with at least one register identifier stored in the assigned charge register. The provision of the energy is aborted, for example, if a charging process is not started within a predefined start time interval at the charging point of the charging station or if a charging process is started with the charging identifier read in via the common input means at another charging point of the charging station.

A charging station designed to carry out the method according to the invention comprises at least one and optionally two or more charging points, a housing with an opening and a door or flap optionally opening or obstructing the opening with a lock. Depending on the charging point, at least one plug-in element is provided, via which an electrically operable vehicle is connected to the charging station. In addition, at least one input means for a charge identifier is provided. The charging station also has a control unit. In any case, a load register with a memory and a processor for carrying out a memory routine is provided as part of the control unit. Furthermore, an input means arranged behind the door or flap of the charging station for each charging point of the charging station is installed with limited access. The at least one input means is in operative connection with the control unit of the charging station.

From the other dependent claims and the following description further advantages, features and details of the invention can be found. There mentioned features may be essential to the invention individually or in any combination. Naturally, features and details of the method described in accordance with the invention also apply in connection with the charging station designed for carrying out the method and vice versa. Thus, the disclosure of the individual aspects of the invention can always be referenced reciprocally. The drawings are merely illustrative of the clarification of the invention and are not of a restrictive nature.

Show it:

1 a first charging station according to the invention with two charging points and two each associated with a charging point input means and

2 a second charging station according to the invention with two charging points with a common input means for the two charging points.

A charging station according to the invention 100 to 1 sees a case 110 in front. On the case 110 an opening is provided, which by means of a door 120 is closed. The door 120 can through a castle 130 locked or optionally released. At the charging station 100 a total of 2 charging points are provided. A first charging point sees a first control unit 140 , a first, at the charging station 100 battered charging cable 142 and one end to the first charging cable 142 provided first plug element 148 in front. In addition, the first charging point of the charging station 100 a first input means 146 assigned, which is exemplified in the manner of an RFID reader. A second charging point of the charging station 100 is a second control unit 160 , a second, at the charging station 100 battered charging cable 162 with a plug-in element 168 and a likewise designed in the manner of an RFID reader second input means 166 assigned.

In each case are for the first charging point and the second charging point of the charging station 100 limited access behind the door 120 a first actuating element 144 and a second actuator 164 intended. An actuation of the actuators 144 . 164 is only possible if the door 120 is open. The in 1 illustrated outbreak in the door 120 is insofar only intended to clarify the arrangement of the actuators 144 . 164 inside the charging station 100 , In reality, the door is 120 formed closed over the entire surface.

To perform a charge on the first charging point of the charging station 100 becomes a charging ID for a vehicle or for a user via the first input means 146 read. In a load register, which is associated with the first charging point and which, for example, as part of the control unit 140 is realized, at least one register identification is deposited, which is the Identification of an authorized user or vehicle for this charging point is used. The read in charge identifier is compared with the at least one register identifier. If the charging ID matches the register ID, the charging station will be at the first charging point 100 Energy provided. The user is thus able to perform a charging process for the vehicle. The provision of the energy at the first charging point is aborted, for example, if a charging process is not started within a predetermined starting time interval.

An energy supply in the context of the invention is given when a voltage is applied to the charging point or charging readiness is created in a suitable manner. It is so far not required that energy is fed into the energy storage of the vehicle. In this respect, for example, the charging station at the charging point, the energy can be provided and the actual charging process begins at the initiative of the vehicle.

For example, a plurality of register identifiers are stored in the load register of the first loading point. The majority of the register identifiers defines the group of authorized users or vehicles that are allowed to perform a charging process at the first charging point. The over the first input means 146 The read in charge identifier is then compared with each individual register identifier. If at least one register identifier matches the read-in charging code, energy is provided at the charging point.

In an analogous manner, the provision of energy at the second charging point of the charging station works 100 , In this case, a charging identifier via the second input means 166 read. A comparison of the read in charging identifier is done with the load register of the second charging point, which preferably as part of the control unit 160 of the second charging point is executed.

To describe the loading register of the first charging point for the first time or to include a new register identification in the loading register, the door is 120 the charging station 100 opened and the first charging point associated with the first actuator 144 actuated. The charging station 100 is then in a register initialization mode. Subsequently, a charge identifier via the first input means 146 read. The read in charge identifier is then stored in the load register. The deposit is preferably made at a free memory of the loading register. If there is insufficient storage space available in the load register, a stored single register identifier or a register identifier stored longest in the load register is overwritten with the newly read in load identifier. If the load register is dimensioned in relation to the memory so that exactly one register identifier can be stored, the stored register identifier is overwritten whenever a new load identifier is read in. If a plurality of register identifiers are simultaneously stored in the load register, the oldest register identifier is overwritten. For this purpose, the register identifier has a memory data or a pointer value correlated with the memory sequence stored in the load register.

It is conceivable that a charging identifier is read several times in the loading register of the charging point. Ultimately, in this way, a charging point, which theoretically has a loading register with a memory designed to hold ten register identifications, can be released for only one authorized user or for a single vehicle by reading the same charging identifier ten times in succession into the loading register. At the same time, by completely describing the memory with a single, same charge identifier, it ensures that all other previously stored charge identifiers are cleared.

2 shows a second embodiment of a charging station according to the invention 100 , The charging station 100 is executed without battered charging cable. It is insofar as designed in the manner of a plug plug-in element 148 . 168 intended for the two charging points. In the plug-in elements 148 . 168 In this respect, mating plug elements of an external charging cable are used to connect the vehicle to the charging station.

The charging station 100 to 2 sees a common input device 156 for the two charging points in front. If, in the normal operating state of the charging station, a charging identifier via the input means ready to receive 156 is read in, the charging identifier is compared with the register identifiers stored in the charge registers of the two charging points. If the charging ID is stored in one of the two loading registers, the assigned charging point is unlocked. If the charge identifier is stored in both charge registers, both charging points of the charging station 100 unlocked. The user can then use the vehicle with any charging point of the charging station 100 connect.

If a charging process is not started within a defined start time interval at an activated charging point or if a charging process using the shared charging identifier at another charging point of the charging station 100 is started, the charging point is deactivated. For example, an activated charging point can be actively or specifically deactivated by the user, for example, by the charging identifier once more via the input device 156 is read.

In the register initialization mode of the charging station 100 the charging identifier is also via the common input means 156 read. The assignment to the load register of the first charging point or the second charging point is made by the choice of the actuating element 144 . 164 , If before the reading of the charging identifier, the actuator 144 is actuated, the charge identifier is deposited as a register identifier in the load register associated with the first charge point. In contrast, the second actuating element 164 actuated and then read in the charging identifier, this is stored as a register identifier in the load register of the second charging point.

In order to simplify the reading of load identifiers into the load register and make them secure in the register initialization mode or in the normal operating state, optical and / or acoustic signals can give the user feedback on the operating steps. For example, after reading in a charging identifier, an acoustic signal can be generated or a shared charging point can be identified by an optical signal.

As vehicles according to the invention all automobiles (cars, trucks, RVs, two-wheelers, etc.), rail vehicles (especially locomotives), watercraft (ships), aircraft and trailers (caravans), mobile stalls etc.
