COMBI CHARGING STATION OR BASE STATION FOR ELECTRIC VEHICLES

The present invention relates to a universal charging station for electric vehicles of all kinds, ie for electric scooters or scooters and electric bicycles, light electric vehicles (LEV), all electric cars and SUVs to trucks and other battery-electric devices. The term "combi charging station" seems to have become common for such universal charging stations, standing for charging stations that have several types of charging (e.g. both using alternating current and direct current, with different power levels) and different charging connections (e.g. Type 2, CCS or CHAdeMO) offer. A combination charging station according to the invention should also be used as a so-called base station, i.e. as a base location for the rental and return of electric vehicles. Furthermore, the present invention also relates to two novel methods for using a respective combined charging station as disclosed. The invention applies equally to charging stations that are set up at a site or also to so-called wall boxes that are mounted on a wall.

Apart from legal regulations and other standards, charging stations, also commonly called charging stations, or combined charging stations, have to meet a variety of requirements or criteria. For example, they must remain within a specified temperature window, not least because of the increasing power output and the resulting higher waste heat from the electrical and electronic components, but also at high outside temperatures and/or in direct sunlight inside. Usually, ventilation grilles and fans or fans are used for this, but the former also allow dust and dirt to penetrate and the latter require temperature management and consume electricity.

Furthermore, not least against the background of safety against electric shocks, keeping the charging station dry in rain, snow and fog or against condensation is important, both with regard to the interior of the charging station and the operating elements such as plugs, sockets, charging cables and interfaces or displays. Flat roof surfaces on which rainwater can stand or on which snow can accumulate are disadvantageous, as are simply straight vertical surfaces of an outer body of the charging station, on which the water can flow down. Even simple projections with sloping surfaces from these vertical surfaces only offer little protection against moisture and dripping water.

Furthermore, conventional charging stations usually have one or more slots in which the appropriate charging plug is “supplied” when not in use. However, the slot and the head of the charging connector are not really reliably protected against moisture and dripping water. Another disadvantage of this arrangement is that a customer who prefers to use their own charging cable for their electric vehicle must pull the charging plug of the charging station out of its slot and plug their own charging plug into the slot for the charging cable they have brought with them, and thus now with the bis to the 3.50 m long charging cable of the charging station and does not know what to do with it. If there is no extra holder on the combination charging station, he will lay the charging cable with the open charging plug on the floor. And a simple holder, on which the unused, open charging plug is held for the duration of the charging process, harbors the risk that the customer will not put the charging plug of the charging station back in its slot when the charging process is complete and after unplugging his own charging plug . It also happens that customers use the charging cable of the charging station but simply leave it on the floor after use due to negligence.

[0005] Foreign bodies can inadvertently penetrate into charging plugs that reach the ground. Unfortunately, however, it also happens again and again that the charging plugs or the slots are the target of vandalism and their openings are covered with small stones, sticks

Chunks, chewing gum, ballpoint pens or many other things can become clogged.

It is also disadvantageous in known charging station arrangements that the charging cables attached to the charging stations have a not inconsiderable value, for example due to the copper they contain, and are sometimes stolen.

The object of the present invention is to provide a universal or so-called combination charging station that meets the above criteria in an improved way. The disadvantages of known combination charging stations should be eliminated completely or largely if possible.

The solution to the problem consists initially in the design of an outer body of the combination charging station according to the invention, which has ventilation openings in a lower area and in an upper area. In addition, the outer body preferably envelops an inner body in such a way that an air gap is left between the inner wall of the outer body and the outer wall of the inner body. The sum of the features of this arrangement according to the invention ensures that air in the air gap rises when heated, escapes through the upper ventilation openings and thus creates a cooling suction or a cooling circulation of fresh air inside the combination charging station, sucked in through the lower ventilation openings. One can therefore speak of a misused chimney effect principle, misused insofar as the combustion is not improved, but ventilation and cooling is achieved, preferably even without any electrically driven fans or fans.

Furthermore, it was found that the upward suction or the circulation of the intermediate air can be further improved if a tapering inner diameter of the inner wall of the outer body is preferably provided approximately in the middle region of the arrangement described. One can speak of a "waisting" of the outer body, which can only be realized inside on the inner wall of the outer body, or also on the outside, i.e. the outer body can also have a constant wall material thickness, incidentally preferably made of a glass-fibre reinforced plastic, which continues to be used preferably non-oil based and recyclable. In any case, with a constant wall material thickness of the outer body, the external aspect or the design of a combination charging station according to the invention would also be tapered. The upward suction, which is further improved in this way according to the invention, and the resulting further improvement in cooling inside the combination charging station according to the invention, is principally due to the so-called Venturi or Bernoulli effect, which, in simple terms, means that the flow rate of a fluid or flow gas, such as e.g Air, when flowing through, increases with a decreasing flow diameter.

[0010] Still concerning the shape of a combination charging station according to the invention, in a preferred embodiment it has a roof surface or a cover which is curved or inclined and is also preferably equipped with a small run-off edge or -rinnenkontur. Incidentally, a sloping roof surface that is oriented towards the strongest solar radiation, along with the outer wall of the combi charging station that is roughly oriented in the same direction, is also best suited for carrying or integrating a small solar panel that already supplies the combi charging station with power, for example for its standby mode ensures. Another advantage of a curved or sloping roof surface is that it is not suitable as a storage area for beverage cans, bottles or rubbish, or even for wallets or mobile phones.

A preferred embodiment variant of a combination charging station according to the invention preferably does not provide charging cables arranged on it, but only slots. A charging plug on a charging cable can only be provided as a reserve, but then preferably—as is known from petrol pumps—rolled up inside the combination charging station or inside a housing that is preferably arranged underground.

Furthermore, it is preferred to provide the slots not only with a protective flap, but with a sliding door, preferably by means of one or two servomotors per

Sliding door or motor-controlled per slot so that it only opens when the customer and his charging request have been unequivocally identified. For this purpose, the locking mechanism of the sliding doors can be guided by rails or racks and is shown in detail below in a figure in a preferred embodiment variant. The locking mechanism also preferably provides an opening position of the sliding door that is on the inside relative to the outer wall of the outer body and a closed position in which the sliding door comes to rest flush with the outer wall of the outer body. Furthermore, it is optionally provided during the charging process, i.e. when the charging plug is plugged in, to move the sliding door inside the outer body from above by means of its or their servomotors to the plugged-in charging plug in a position that fixes, arrests or even blocks it.

Due to the identification of the customer and the charging process desired or rather suitable for his electric vehicle, according to the invention only that sliding door is opened which releases the matching slot located behind it.

The customer can be identified based on WiFi using his smartphone. However, Bluetooth®, NFC, IOT or mobile communications can also be considered as other types of transmission. Furthermore, a QR-based app would be possible, either through a charging station-side QR scanner or through a smartphone-side QR scanner. Furthermore, for identification, but also for communication between combination charging station and customer or between combination charging station and vehicle or between combination charging stations among themselves, WLAN and the so-called Internet of Things (IOT) as well as radar or lidar, microphones, tactile Systems or sensors into consideration. Gyro sensors can also be considered as the latter, for example, which generate a transmission signal or radio signal in the event of a specific, stored movement pattern, preferably using transmission-safe Ultra Wide Band (UWB) radio technology.

Furthermore, distance and infrared sensors on a combination charging station according to the invention can also be considered as sensors, not only for distance measurements to an object that appears or for detecting a movement of this object in front of the combination charging station, but also, for example, for Feature to power up the charging station that is in a current-free or at least current-reduced sleep mode into a more ready-to-operate standby or fully active operating mode, but only as soon as there is a sufficiently relevant movement in front of the combi-charging station.

However, so that identification can also work without a smartphone, an interface and a display for entering a PIN code or detecting an NFC chip card is also provided on a combination charging station according to the invention. Furthermore, one or more cameras, which also enable smartphone-free identification. This can be done, for example, by storing face recognition software, preferably without accessing a general face recognition, but only one previously expressly stored in the system. In any case, all data protection guidelines are strictly observed. The cameras would also be able to capture the license plate number and type of vehicle via image recognition. Furthermore, it would still be possible according to the invention to hold the charging plug of the vehicle in the camera, whereupon the appropriate charging process is also made available by means of image recognition. It would also be quite possible to also attach customer-identifying codes such as color, QR, number or bar codes to the charging connector.

A further preferred embodiment variant of a combination charging station according to the invention provides the necessary connections and controls in order to be part of an intelligent power grid, a so-called smart grid. Among other things, this provides that on the one hand particularly cheap or particularly ecological electricity can be obtained, but on the other hand that the electric storage device that is currently attached to the combination charging station can make its electricity available to the smart grid, keyword bidirectional charging.

Not least for making available or also "bunkering" large amounts of electricity or for buffering current peaks in the smart grid, a combination charging station according to the invention is preferably equipped with one or more accumulators and/or capacitors. In

According to the invention, capacitors integrated in a combination charging station also open up possibilities for extreme rapid charging, but also as power support or as redundancies.

As already mentioned above, a combination charging station according to the invention is equipped less with charging plugs located on charging cables and more with slots for charging plugs that are arranged on the electric vehicle. And, as also explained above, the slots suitable for the required charging process are released by automatically or motor-driven sliding doors. In this regard, an optional embodiment variant of a combination charging station according to the invention is also possible, in which a corresponding sliding door opens as described, but the appropriate slot is delivered again by motor on a drum or a sliding mechanism of the opening. In any case, regardless of whether it has fixed slots or those that can be delivered, a combination charging station according to the invention offers all known and common charging connections and also all the corresponding different types and strengths of charging.

As already mentioned in paragraph [0001], a combination charging station according to the invention is also designed as a base station for the rental and return of electric vehicles. A combination charging station according to the invention meets this property on the one hand through the large number of connections, but in particular also the following feature: It is also provided according to the invention, in addition to the electronic locks for this that are actually already known in the profession, to also mechanically lock the charging plug in the slot . This blocking device comprises one or more locking pins which, operated by means of actuators or servomotors, can be moved in and out of corresponding openings in the charging connector sleeve. Such openings are already present on all common charging plugs anyway. According to one embodiment variant, the locking pins can be spring-loaded, so that the charging plug is simply inserted into the locked position by overcoming the spring force, without the actuators or servomotors having to become active. Only when the locking device according to the invention is unlocked do the actuators or servomotors become active by retracting the locking pins, again against the resistance of the spring force.

The described blocking device according to the invention finally offers a company that rents electric vehicles a handle against unauthorized removal of the electric vehicle from the charging station on the one hand, but on the other hand also a reliably detectable return solely at the or one designated location. If it can now be clearly defined in this way at what time the rental period begins and when it ends, i.e. only after successful locking back into the locking device, one could perhaps get the bad habit under control, especially electric scooters after use carelessly somewhere in the city, in the forest or to "dispose of" in the river.

In addition, the locking device according to the invention described offers increased security. It is no longer possible to disrupt or interrupt an ongoing charging process and thus ensure a smooth charging process without first unlocking the locking pins. In addition, an intermediate step that increases safety is included in the charging process, during which the voltage can be switched off. This means that the charging plugs can be pulled off without being under voltage, as was previously the case. Provision is also made for the locking device to remain in its respective locked or unlocked status even in the event of a power failure.

At least one display is preferably arranged on a combination charging station according to the invention, and if at least two are then preferably arranged opposite one another. This means that two consumers should be able to use the combination charging station at the same time, or one consumer should be able to select the display that is more comfortable for him in terms of position or incidence of light. In addition, the combination charging stations according to the invention should be able to be arranged in multi-row parking spaces, ie be accessible from at least two sides. The displays are preferably high-resolution, optionally touch-sensitive and colored so that color-coded information can also be displayed or entered. Furthermore preferably

Consider modern OLED displays that can also withstand sub-zero temperatures.

[0024]Lights are preferably also provided in a double and opposite arrangement. They are preferably designed as glare-free lighting bars and illuminate the surroundings of the combination charging station preferably only when required, for example triggered by the passive infrared sensor described. The preferred lighting bar can optionally also light up in different colors so that it can be signaled when the combination charging station is free, occupied or out of order or when a charging process has ended. The slots or the small sliding doors of a combination charging station according to the invention can also be illuminated with rings surrounding them and furthermore preferably also indicate their respective function with different colors. The double and opposite arrangement of the lighting bars and also the displays is optional and is of less importance in a wall box according to the invention.

A combination charging station according to the invention is preferably covered with a fluorescent film or painted with such a color or even fluorescent particles are incorporated into the material of the outer body.

The large number of sensors and detection systems described would make it possible to detect an autonomously driving electric vehicle that has approached the combination charging station according to the invention or has even been piloted by it. In this case, a combination charging station according to the invention comprises at least one robotic arm, which, based on cameras and sensors, picks up the charging plug of the electric vehicle and inserts it into the appropriate slot. However, a contact-free charging process using induction is also possible.

The base of a charging station according to the invention preferably comprises a lockable ball joint on a conductive grounding mounting post, so that setting a charging station according to the invention eliminates the need for separate grounding and the pouring of a concrete base, which must be horizontal depending on a particular terrain orientation and thus enables vertical installation of the charging station.

The list of reference symbols is part of the disclosure.

The invention is explained in more detail symbolically and by way of example on the basis of figures. The figures are described coherently and comprehensively. They represent schematic and exemplary representations and are not true to scale, not even in the relation of the individual components to one another. The same reference symbols mean the same component, reference symbols with different indices indicate functionally identical or similar components.

It show here

Fig. 1 shows a symbolic and exemplary view of a known combination charging station according to the prior art, with the three most common plug types CHAdeMO, CCS and Type 2, each arranged on a charging cable of the combination charging station and each plugged into a corresponding slot or . provided;

[0037] FIG. 2 shows a symbolic and exemplary perspective view of a combination charging station according to the invention, with a waisted outer body;

[0038] FIG. 3 shows a symbolic and exemplary side view of the combination charging station according to the invention from FIG. 2, with three lockable slots arranged as an example;

[0039] FIG. 4 shows a symbolic and exemplary sectional view of the combination charging station according to the invention from previous FIGS. 2 and 3, with an inner body which is enveloped by the waisted outer body;

[0040] FIG. 5 shows a symbolic and exemplary representation of the technical structure of a lockable slot and a corresponding locking mechanism and

[0041] FIG. 6 shows a symbolic and exemplary sectional view through a slot of a combination charging station according to the invention, which also includes a blocking device according to the invention.

1 shows a symbolic and exemplary view of a combination charging station 100 according to the prior art, as it is, for example, at the Medenbach West motorway service station near Wiesbaden, Germany, symbolically indicated as installation site AO.

It can be seen in this Fig. 1 that the combination charging station 100 has an outer housing or an outer body 1, which in turn forms a cover or a flat roof surface 2 and outer body walls 3a-3c, more precisely a front wall 3a, a left side wall 3b and a right 3b. The outer body 1 stands with a base S on the floor.

A projection 4 is arranged on the front wall 3a, which has a surface 5a sloping backwards upwards in an upper region and a surface 5b sloping backwards downwards in a lower region. Arranged on the latter are charging cables 6a-6c, each hanging in a loop on the floor and each ending in a charging plug 7a-/c, with charging plug 7a being a so-called CHAdeMO charging plug and charging plug 7b being a so-called CCS charging plug ( Combined Charging System) and the charging plug 7c is a so-called type 2 charging plug. The corresponding charging connections can be recognized not only by their shape, but also by the charging connection symbols 11, which are above a corresponding

matching slot 10a-10c are shown.

Each of the charging plug 7a-7c is plugged into its corresponding slot 10a-10c and is additionally held by a respective retaining plate 19a-19c.

Furthermore, it can also be seen in this Fig. 1 that an attachment 8 is also arranged on the front wall 3a, which forms a depression 9a-9c for each of the slots 10a-10c, for a more or less protected or sunken receptacle of the respective charging plug 7a-7c. This attachment 8 also forms an inclined surface 5c in its upper area.

shows on the one hand, by a high number of six ventilation grilles 18a-18f, arranged in two ventilation grille rows 12a and 12b, that the combination charging station 100 according to the prior art has a high cooling requirement. On the other hand, the original photo from which this Fig. 1 is traced shows that the protection against dripping moisture is insufficient. Namely, if you look closely, the original photograph shows water droplets everywhere, even on the rearwardly downwardly inclined surface 5b of the projection 4 and even on the charging plugs 7a-7c, although they are buried in the recesses 9a-9c. In addition, the charging cables 6a-6c touch the damp and dirty floor.

2 shows a symbolic and exemplary perspective view of a first embodiment variant of a combination charging station 100a according to the invention at an arbitrary installation site AQ+, which is shown only symbolically. As already mentioned at the beginning, the installation site AQ+ can also be a wall. The main differences, which are visible apart from the inner workings and inherent technical properties, can be seen in four respects.

First, an outer body 1a is fitted with a waist T and formed by an outer body wall 3d, which is closed off at the bottom by a base Si with ventilation openings 13a and at the top by a curved roof surface 2a with ventilation openings 13b.

Secondly, the outer body 1a or the outer body wall 3d forms a body side 20a on which a display 15 with a camera 16 and a vertically arranged lighting bar 17 are arranged.

A third main difference of the combination charging station 100a according to the invention from FIG. 2 compared to the known combination charging station 100 according to the prior art from FIG. 1 is that the combination charging station 100a according to the invention has no charging cable and no charging plug , but only slots 10d-10f, which are each arranged behind a sliding door 14a14c on a body side 20b.

3 shows the combination charging station 100a according to the invention from the previous FIG. 2, but from a body side 20c, which is opposite the body side 20b from FIG. Two slots 10g and 10h are provided behind sliding doors 14d and 14e on this body side 20c.

[0053] Furthermore, it can be seen that the lighting bar 17 on the body side 20a can optionally also be designed to be raised in order to offer an improved lighting angle.

Furthermore, a body side 20d opposite the body side 20a is also equipped with a display 15a and a camera 16a, preferably mirror-symmetrical to an axis of symmetry SA, both of which are only indicated by means of arrows, and also a raised lighting bar 17a.

4 again shows the combination charging station 100a according to the invention from the previous FIGS. 2 and 3, but this time in a sectional view AA, the orientation of which is shown in FIG. It can thus be seen in this Fig. 4 that the outer body 1a or the outer body wall 3d encloses an inner body 21 in such a way that there is cooling air circulation LZ all around in an air gap 22 rising from the lower ventilation openings 13a to the upper ventilation openings 13b.

The inner body 21 preferably stands on base feet 23a and 23b and is also preferably made of metal, with recesses 24.

The already known sliding doors 14a-14e are shown in a respective closed position flush with the outer body wall 3d. These closed positions correspond to the positioning of respective slots 10d-10h, which are only shown symbolically and are preferably arranged on the inner body 21.

Also shown only symbolically above each sliding door 14a-14e is a respective rail 25a-25e. These rails 25a-25e and a sliding mechanism or sliding door locking mechanism not shown here preferably ensure a respective opening position of the sliding doors 14a-14e that is on the inside relative to the outer body wall 3d, and also preferably the described closed position, which is flush with the outer body wall 3d completes.

5 shows a preferred embodiment variant of a combination charging station 100b according to the invention with a sliding door closing mechanism 200 for a closing process of a sliding door 14f from a shown OOpening position OP into a closing position SP within a sliding door or slot opening 26. This sliding door - or slot opening 26 is located in an outer body wall 3e opposite a not shown in this figure slot for receiving a charging connector.

The closed position SP of the sliding door 14f is preferably sealed by means of a rubber seal 27 and is flush with the outer body wall 3e. Reaching this closed position SP requires, on the one hand, a movement within a vertical offset VV. For this purpose, a carriage 32 is arranged on the back of the sliding door 14f, on the sides of which there are wheels, rotatable pins or rollers 33a-33d. The carriage 32 runs in a rail profile 25f by means of these rollers 33a-33d, driven by the rotation of a threaded spindle 30 in a spindle nut 31 fixedly connected to the carriage 32. The rotation of the threaded spindle 30 in turn is driven by a motor M.

On the other hand, reaching the preferably flush closed position SP of the sliding door 14f also requires a movement within a horizontal offset HV. For this purpose, the rail profile 25f has a curvature 34 and the threaded spindle 30 or the entire motor M can also swivel because it is rotatably mounted on a motor bearing 28 by means of a swivel joint 29 .

[0062] FIG. 6 shows a further embodiment variant of a combination charging station or base station 100c which is also characterized by a mechanical locking device 300 only symbolically and schematically according to the invention.

A slot 10i is provided for this purpose, shown by way of example as one for a CCS charging connector, with a corresponding form-fitting negative molded housing 35 and contact pins 36a-36g protruding from bores.
