Description

Plug device for charging an energy store of a motor vehicle with electrical energy, motor vehicle with at least one such plug device and

Charging infrastructure with at least one such plug device

The invention relates to a plug-in device for charging an energy store of a motor vehicle with electrical energy according to the preamble of patent claim 1. The invention also relates to a motor vehicle with such a plug device and a charging structure with such a plug device.

Plug devices for charging normally always include a plug element, which can be designed as a charging plug, and a socket element, which can be designed as a charging socket, the plug element and the socket element having a corresponding shape, so that they can be inserted into one another.

Such a plug-in device for charging an energy storage device of a motor vehicle with electrical energy is already known, for example, from DE 10 2014 215 123 A1. The plug-in device has a first plug-in field, which has first electrical contacts for transmitting electrical current for charging the energy store. In addition, the plug-in device has a second plug-in field, which has second electrical contacts for transmitting electrical direct current for charging the energy store.

The object of the present invention is to provide a plug-in device, a motor vehicle and a charging infrastructure, so that energy stores of motor vehicles can be charged in a particularly needs-based manner and with particularly high charging currents.

This object is achieved by a plug-in device with the features of claim 1, by a motor vehicle with the features of claim 12 and by a Charging infrastructure with the features of claim 13 solved. Beneficial

Refinements with expedient developments of the invention are specified in the remaining claims.

The plug device on the motor vehicle for charging with electrical energy is usually designed as a plug element in the form of a socket element, a so-called charging socket, into which a plug element of the charging infrastructure in the form of a charging plug can be inserted. Conversely, the plug device of a charging infrastructure is usually designed as a plug element in the form of a charging plug, which can be plugged into a socket element on the motor vehicle in the form of a charging socket. Theoretically, this is of course also possible in reverse that the charging plug is arranged on the motor vehicle and the charging socket on the charging infrastructure, or that there can be mixed forms in which both plug elements of the plug-in device have both plug features and socket features, as long as the shapes correspond to one another and one Allow plugging. The design of the plug and socket is mostly chosen for safety reasons, but this also allows all possibilities in the sense of bi-directional charging of electric vehicles in both directions.

In order to further develop a plug-in device of the type specified in the preamble of patent claim 1 in such a way that energy stores of motor vehicles which are designed to store electrical energy or electric current and are also referred to as electrical energy stores are particularly needs-based and have a high level

Charging currents and thus can be charged in a short time, it is provided according to the invention that the plug-in device has at least a third plug-in field, which has third electrical contacts, by means of which direct current for charging the energy storage device of the motor vehicle can be transmitted in parallel with the second electrical contacts.

Such a plug device for charging an energy store of a motor vehicle with electrical energy has a first plug element as a plug element and a second plug element as a socket element.

In accordance with the previously known plug-in devices, the plug-in device according to the invention also has a first plug-in field, which has first electrical contacts for transmitting electrical current for charging the energy store and further contacts for data exchange between the motor vehicle and a charging infrastructure during the charging of the energy store. In addition, the plug-in device has a second plug-in field with second electrical ones

Contacts for the transfer of direct current to charge the energy store.

According to the invention, the plug device has at least a third plug field with third electrical contacts, by means of which parallel to the second electrical contacts

Contacts direct current for charging the energy storage is transferable.

The at least three plug-in fields of the plug-in device are in both plug-in elements of the plug-in device, that is to say both in the plug element and in the

Socket element, as a structural unit are non-detachably or reversibly detachably connected

The further contacts for data exchange are only arranged in the first patch panel and the second and further patch panels (18, 22, 26, 30) have no further contacts for data exchange.

With the feature that by means of the third electrical contacts electrical

Direct current for charging the energy store can be transmitted in parallel with the second electrical contacts, it is to be understood that the second electrical contacts and the third electrical contacts are designed to be parallel, that is to say at the same time direct current, that is to say an electrical current having a direct voltage for charging the Transfer energy storage. In other words, during a charging process, by means of or during which the energy store of the motor vehicle with electrical energy or

electric current is charged, direct current is transmitted in parallel or simultaneously via the second electrical contacts and via the third electrical contacts. The direct current, which is transmitted simultaneously by means of the second contacts and the third contacts, flows or flows through the second contacts and through the third contacts and is used to store the energy

To charge motor vehicle with electrical energy or with electrical current. The direct current which is transmitted by means of the second contacts and the third contacts and thus flows through the second contacts and the third contacts is, for example, at least partially fed or stored at least indirectly or directly into the energy store, as a result of which the energy store is charged.

Since both the second contacts and the third contacts are designed to transmit direct current, that is to say direct current to charge the energy store, the third contacts and the second contacts are also used as direct current Contacts or DC contacts. A first of the second contacts forms

For example, an electrical positive pole, with a second of the second contacts forming an electrical negative pole, for example. Accordingly, for example, a first of the third contacts forms an electrical positive pole, while a second of the third contacts forms an electrical negative pole. The respective electrical positive pole is also referred to as DC +, for example, the respective electrical negative pole also being referred to as DC- for example.

The respective plug-in area is distinguished, for example, by the fact that a plug, with the formation of a respective plug-in connection, either with the first plug-in area or with the second plug-in area or with the third plug-in area or simultaneously with all of them

Patch panels can be connected, for example to connect the plug at least electrically and preferably also mechanically to the respective patch panel. The respective patch panel summarizes its respective contacts to form a respective spatial arrangement of the respective contacts of the respective patch panel, so that the respective patch panel as such has its own field that is independent of the other patch panel and a respective area that is independent of the respective other or other patch panels is, in which the respective contacts of the respective patch panel are arranged in a predeterminable or predetermined spatial arrangement. The plug-in fields are spaced apart from one another and / or geometrically delimited from one another, in particular in such a way that the respective plug-in field combines the respective contacts of the respective plug-in field into a predeterminable or predetermined spatial arrangement.

One of the findings on which the invention is based is that previous conventional charging interfaces, via which energy stores of motor vehicles can be charged with electrical energy, enable charging currents or charging power that are or are inadequate in particular when energy stores with a very large storage capacity contain electrical energy should be loaded for a short time. This applies in particular, for example

Commercial vehicles such as lorries or buses, in particular buses, which can only be charged for a very long time, for example by means of a charging power of 400 kW.

In contrast, the plug-in device according to the invention, in particular its modular structure, enables charging powers of more than 400 kW, in particular of far more than 500 kW, in particular of up to and more than 1.2 MW in particular to be able to implement needs-based ways. If, for example, a conventional charging interface is available, it can be electrically connected to the first plug-in panel and to the second plug-in panel, for example, while there is no connection to the third plug-in panel. As a result, a charging current of 400 A or 500 A can be realized, for example, so that depending on the voltage level

Charging device also a charging power of up to 400 kW or 500 kW can be realized. However, if a charging interface is available which can be at least electrically connected to the first patch panel, the second patch panel and the third patch panel at the same time, particularly high charging powers or particularly high charging currents of, for example, 400 A or 500 A per patch panel can be realized so that then a total of 1200 A up to 1500 A or more can be realized. For this purpose, the first patch panel and the second patch panel are supplemented by the third patch panel, in particular in a modular manner. The respective patch panel can have at least two contacts. At least one of the respective patch panels preferably has at least or exactly three contacts or at least or exactly three contact pairs. With a total of four current-carrying patch panels, even higher charging currents can be achieved, so that charging currents of up to 1600 A or up to 2000 A can flow through the plug device.

Increased plug-in forces for connecting a charging interface to the plug-in device according to the invention and / or increased pulling forces in order to separate a charging interface from the plug-in device according to the invention can be overcome with the aid of a mechanical and / or electrical plug-in and / or pulling aid, in particular mechanized. Such a plug-in and / or pulling aid comprises, for example, a spindle, by means of which the interface can be connected to the plug-in panels particularly easily or can be detached from the plug-in panels. A so-called

Charging communication, in the context of which data is exchanged during a charging process, any safety devices and / or other devices are based, for example, on proven standards or on tried-and-tested basic modules and are further used or shared.

The modular expansion of the first patch panel and the second patch panel by the third patch panel can be used, for example, as a commercial vehicle, in particular as a

Truck or bus, trained motor vehicle or its

Energy storage with very high charging capacities and thus can be charged in a short charging time. The plug-in device according to the invention is compatible with previous, conventional charging interfaces, in particular plugs that are used, for example, under Forming a respective plug connection with the first patch panel and the second patch panel can be electrically and preferably also mechanically connected. A charging infrastructure for charging electrical energy storage from

Motor vehicles can be gradually built up and, for example, upgraded so that the respective charging interface, in particular a respective plug, can be at least electrically connected to the first, the second and the third plug-in field at the same time. For example, on depots can be longer

Low-cost standard charging stations according to the CCS standard (CCS - Combined Charging System - combined charging system) are installed, whereas

In contrast, more expensive charging stations for realizing very high charging currents of over 400 A per plug contact for charging or depending on the voltage level

Charging powers of over 400 kW, in particular of over 500 kW, are designed for recharging for long distances. At least the second charging contacts and the third charging contacts are designed as DC charging contacts, since the second and third contacts are designed to carry or conduct electrical current having DC voltage. The second and third contacts can be operated in parallel and thus conduct and transmit direct current in parallel or simultaneously, thereby, for example, thereby distributing the direct current in parallel as a charging current. This can avoid excessive stress on a single DC connector.

In order to be able to charge the energy store in a particularly needs-based manner and thus both with particularly high charging currents and also with the charging currents which are lower than that, it is provided in an advantageous embodiment of the invention that the second patch panel and the third patch panel have the same external shape. Thus, for example, a connector, also referred to as a plug element, can optionally be electrically connected to the second connector panel, but not to the third connector panel or to the third connector panel, but not to the second connector panel, or a connector can be connected to the second connector panel and to the third connector panel simultaneously can be connected in order to be able to ensure that the energy store is charged in a particularly needs-based manner.

Another embodiment is characterized in that the first electrical contacts are designed to transmit or conduct or carry alternating current. As a result, the energy store can be charged particularly quickly and as required. In particular, it is preferably provided that the first contacts, the second contacts and the third contacts are designed to to transmit or to conduct electrical current in parallel or simultaneously, so that, for example, the energy store can be supplied with electrical current or electrical energy in parallel both via the first contacts and also via the second contacts and the third contacts and thereby charged.

In a particularly advantageous embodiment of the invention, the first patch panel and the second patch panel are formed by a first module, which is designed, for example, as a CCS module. The third plug-in field is preferably formed by a second module which is formed separately from the first module. This creates a modular structure, which means that charging of the

Energy storage can be guaranteed.

The respective module is, for example, at least electrically connected to a charging station via a respective own cable, the cables being able to be designed independently and thus, for example, as respective individual cables. These individual cables are separated from each other, for example. It is also conceivable that the cables are combined to form a cable harness.

The modules can be connected to one another in a non-detachable manner, that is to say in a non-destructive manner. This is to be understood in particular to mean that the modules can be connected to one another and separated from one another without tools. In particular, it is conceivable for the modules to be integral and / or positive and / or

are non-positively connected with each other. In this way, misuse of the plug device can be avoided.

However, it has proven to be particularly advantageous if the modules are connected to one another in a reversibly detachable manner. As a result, the modules which are initially connected to one another can be separated from one another and then reconnected to one another without the modules being damaged or destroyed. In the installed position of the plug-in device, the second module can, for example, be arranged below or above the first module in the vertical direction of the vehicle, or the second module is arranged in front of or behind the first module in the longitudinal direction of the vehicle. In particular, the second module can be attached to the first module in order to be able to keep the installation space requirement particularly low.

The first contacts and thus the first plug-in field enable, for example, a so-called AC charging, also referred to as AC charging, since the first contacts are preferably designed to draw AC electrical current Transfer energy storage. The second and third contacts and thus the second and third plug-in field are preferably designed to implement a so-called DC charging, also referred to as DC charging, since the second and third contacts are designed to supply a direct current for charging the energy store

transfer.

The first plug-in field is preferably also designed to establish a communication connection, in particular a connection, during the charging of the energy store

Communication plug-in connection to be provided, via which data can be exchanged, for example, between the motor vehicle and a charging infrastructure that is external to the vehicle.

In order, for example, to reversibly connect the modules to one another, the respective module in each case has at least one connecting device. About the

The modules are connected to one another, in particular reversibly detachable, by connecting devices. In particular, it is conceivable that the modules via the

Connection devices are locked together or positively connected to each other. This enables a particularly advantageous modular structure to be realized, so that, for example, the first module can be supplemented by the second module as required.

A further embodiment is characterized in that the plug-in device has at least one fourth plug-in field, which has fourth electrical contacts, by means of which parallel to the second electrical contacts and parallel to the third electrical contacts, that is to say parallel to that via the second electrical contacts and the third electrical contacts are carried out for the transmission of direct current, that is to say direct current having electrical voltage, for charging the energy store. In this way, for example, particularly high charging powers or charging currents can be realized, so that energy stores with a particularly high storage capacity can also be fully charged in a short time.

In order to be able to charge the energy store in a particularly needs-based manner, it is provided in a further embodiment of the invention that the third patch panel and the fourth patch panel are arranged uniformly distributed around the first patch panel and / or the second patch panel. In this way, for example, different charging plugs can be connected to the respective patch panel or to one of the patch panels as required, while connecting the plug to another of the

Patch panels are omitted. In addition, for example, plugs can be used accordingly are formed, at least electrically connected to all patch panels simultaneously.

In a particularly advantageous embodiment of the invention, it is provided that the fourth plug-in field is formed by a third module formed separately from the first module and separately from the second module. This enables a particularly advantageous modular construction of the plug-in device, so that the energy store can be advantageously charged. The previous and following

Comments on the first module and the second module can easily be transferred to the third module and vice versa.

The second module and the third module are preferably so-called DC modules, since they enable DC charging of the energy store, in particular at the same time.

In particular, a fourth module with a fifth patch panel, in particular a fourth module designed as a DC module, can be provided, in which case the second, third and fourth modules can then be arranged uniformly distributed around the first module. The second, third and fourth modules then have the same distance in the circumferential direction of the first module, for example in pairs, which is, for example, 90 °. In particular, it is conceivable that the second, third and fourth modules are arranged in a ring-shaped or petal-like manner around the first module. In this case, the second, third and fourth module and thus the third, fourth and fifth plug-in area can be connected to or around the first plug-in area of the first module and / or

or be arranged around the second patch panel of the first module.

Furthermore, it is conceivable that the second and third modules and the fourth module that is preferably provided are simply arranged as a block on the side of the first module, which for example forms a CCS system or CCS module.

If, for example, the modules are permanently connected to one another, they can

Arrangement can not be changed relative to each other, so that the arrangement is given to each other or fixed. The modules or the patch panels then form an entire plug contact, whose shape can no longer be changed.

However, it has proven to be particularly advantageous if the modules are connected to one another in a reversibly detachable manner, so that, for example, the second, third and fourth modules can be reversibly detachably attached to the first module. This makes it possible to add and / or remove the individual modules to form an advantageous CCS plug when in use at the respectively required location, as a result of which an at least almost free configurable connector can be displayed. The plug, which can be configured by connecting the modules as required and optionally, can therefore have different

vehicle-side and thus built-in sockets of respective motor vehicles are plugged in or connected to the respective socket. Then it will be

For example, the configuration of the connector or the intended and, for example, plugged-in modules are recognized and activated, for example via electronics and via communication running via a CCS plug-in contact, so that any modules that are present but not plugged in have no voltage or current when charging.

The plug-in device according to the invention is preferably designed in such a way that it can be locked to the

corresponding plug can be reversibly locked releasably. Furthermore, conventional plug-in aids, such as spindle drives, centered entries,

Ejectors, etc. are used to make the invention

Connect the plug device with a corresponding plug

or to be able to detach from such a connector. Contacting measurements or an identification of inserted contacts, in particular any live contacts and / or an available and receivable one

Voltage and / or an available and recordable current, as well as a

Communication between the motor vehicle and a charging station external to the vehicle can continue to take place via a corresponding standard, in particular the CCS system.

The third plug-in field and the fourth plug-in field and preferably the optionally provided third module provide additional DC charging contacts in addition to the second contacts, which can carry and transmit a high direct current for charging the energy store in parallel with one another and in parallel with the second contacts. As a result, the energy store can be charged with a large amount of electrical energy in a short time. In addition, an overload of the respective contact, also referred to as the charging contact, can be avoided.

It has proven to be particularly advantageous if the second module can be connected or connected to the first module in a reversibly detachable manner independently of the third module and the third module independently of the second module. This means that the second module can be reversibly detachably connected to the first module and can remain connected, while the third module is not connected to the first module or is solved by the first module. As a result, the third module can be reversibly detachably connected to the first module and remain connected, while the second module is not connected to the first module or is detached from the first module. As a result, the plug-in device can be configured at least almost freely and thus be designed as an at least almost freely-configurable plug, since the plug-in device can optionally only relate to the modules only the first module, only the first module and the second module, only the first module and the third module or which has three modules. As a result, the energy store can be charged in a particularly needs-based manner with the aid of only the first module, with the aid of the first and the second module, with the aid of the first and the third module or with the aid of the first, second and third module.

In a particularly advantageous embodiment of the invention, it is provided that the plug-in device comprises at least one plug element, which can be reversibly releasably connected to the first plug-in field and the formation of a plug connection, while the plug element is connected to the second plug-in field and / or to the third plug-in field and / or with the fourth patch panel.

Alternatively or additionally, it is conceivable that the plug element can be connected reversibly detachably to the first plug-in field and at the same time reversibly detachably to the second plug-in field with the formation of a respective plug connection, while the plug element is not connected to the third plug-in field and / or to the fourth plug-in field. Alternatively or additionally, it is provided that the plug element can be connected reversibly detachably to the first plug-in field and at the same time reversibly detachably to the second plug-in field and at the same time reversibly detachably to the third plug-in field, with the formation of a respective plug connection, while the plug element is not connected to the fourth plug-in field . Alternatively or additionally, it is provided that the plug element can be connected reversibly detachably to the first plug-in field, the second plug-in field, the third plug-in field and the fourth plug-in field at the same time. The first, second third and optionally provided fourth plug-in field forms a first plug, for example, in the form of a socket or plug, the at least one plug element being, for example, a second plug in the form of a socket or plug. The first plug and the second plug form a plug-in contact and are to be connected to one another in particular by plugging one into the other

Charge energy storage with electrical energy. The first plug with the detachable modules thus fits, for example, in such a socket, in which not all modules are attached as in the first plug, or a plug with fewer modules also fits in such a socket, which is provided for more modules than the plug having. A control or voltage application and current release of the respective contacts of the respective modules are controlled by electronics by recognizing the inserted, that is to say electrically connected, contacts. The at least one plug element can, for example, if it does not have all the modules, be connected to the first plug, which has all the modules. Furthermore, by using the reversibly detachable modules, it is possible to adapt the first plug to a respective second plug in such a way that the modules are connected to each other in such a reversibly detachable manner that the first plug can be inserted into the second plug or vice versa.

Thus, for example, the first connector can be adapted to a second connector by reconfiguring the modules, that is to say they are connected to one another in a reversible, releasable manner. Furthermore, downward compatibility is conceivable in that the at least one plug element with fewer modules fits into the first plug element if it has more modules than the at least one plug element. With the help of four current-carrying modules contacted during charging, for example, 1600 A or even 2000 A charging current can be realized in order to be able to charge the energy store particularly quickly. With a charging voltage of 800 V, a charging power of up to 1.6 MW would be possible.

The respective contact is designed, for example, as a pin element, which is also referred to as a pin. The respective contact has, for example, a diameter which has a range from 8 mm to 10 mm inclusive, but in particular should only be carried out for contact protection up to 8.5 mm. The respective patch panel can guarantee a charging current of up to 400 A, in particular up to 500 A, so that, in total, particularly large charging currents can be achieved without the need for separate cooling of the patch panels or the contacts. If larger contacts were used, a larger contact area would indeed be feasible, as a result of which contact losses and heat loss can be kept low, but adequate security must then be ensured, particularly with regard to accessibility.

Technically in a motor vehicle, charging electronics for all DC contacts either continue to charge the battery, for example as a battery, in particular as High-voltage battery, trained energy storage as a unit, or each DC contact is assigned its own, in particular full, charging electronics, which is then also assigned to part of the energy storage as a charging system, so that there is full parallelism across the entire system and there are no internal bottlenecks high performance can come. In such a parallel system, the charging electronics naturally also have to ensure that all parts of the energy store can also be charged with only one charging electronics, if only one contact of the plug-in device for charging is present or active. Here, the one or more charging electronics, for example via a matrix circuit with all parts of the

Energy storage connected, so that it is ensured that all parts of a battery can also be charged via such a multiple system.

Another embodiment is characterized in that the first patch panel is designed as type 1 in accordance with the IEC 62196 standard or as type 2 in accordance with the IEC 62196 standard, in particular with the IEC 62196 standard, which is or was valid on August 21, 2018.

Alternatively or additionally, it is provided that the first patch panel and the second patch panel form a combo-1 connector in accordance with the IEC 62196 standard or a combos connector in accordance with the IEC 62196 standard. As an alternative or in addition, it is provided that the third patch panel is designed as type 1 in accordance with the IEC 62196 standard or as type 2 in the IEC 62196 standard. Alternatively or additionally, it is provided that the fourth patch panel as type 1 according to the IEC 62196 standard or as type 2 according to the standard

IEC 62196 is formed. The IEC 62196 standard is also referred to as DIN EN 62196 and refers to the version or version valid on August 21, 2018.

Finally, it has proven to be particularly advantageous if the plug-in device is designed as a plug-in device on the vehicle, which is therefore part of the

Motor vehicle is. Alternatively, it is provided that the plug-in device is a plug-in device external to the vehicle and is therefore not part of a motor vehicle.

A second aspect of the invention relates to a motor vehicle, preferably designed as a commercial vehicle, with at least one plug device according to the invention.

A third aspect of the invention relates to a charging infrastructure external to the vehicle for charging an energy store of a motor vehicle, the charging infrastructure comprising at least one plug device according to the first aspect of the invention. Advantages and advantageous configurations of the first and second aspects of the invention are to be regarded as advantages and advantageous configurations of the third aspect of the invention and vice versa.

Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing. The features mentioned in the description and

Identical or functionally identical elements are provided with the same reference symbols in the figures.

1 shows a schematic plan view of a plug device, designated as a whole by 10, for charging an energy store of a motor vehicle with electrical energy, that is to say with electrical current. This means that the plug device 10 is used to conduct and transmit electrical energy or electrical current for charging the energy store, so that the energy store can be charged by means of the transmitted electrical energy. The energy store is thus designed to store electrical energy. In particular, the

Energy storage can be designed as a high-voltage component, which has an electrical voltage, in particular electrical operating voltage, which is greater than 50 V and is preferably several hundred volts. The motor vehicle is, for example Commercial vehicle and preferably designed as an electric or hybrid vehicle. Thus, the motor vehicle in its completely manufactured state has at least one electrical machine, by means of which the motor vehicle can be driven electrically. For this purpose, the electrical machine is supplied with electrical energy, which in the

Energy storage is stored.

1 shows a first embodiment of the plug device 10. The plug device 10 is, for example, part of the motor vehicle, which thus has the plug device 10 in its completely manufactured state. In particular, the

Plug device 10 can be designed as a vehicle-side charging connection, for example in the form of a socket element or charging socket, with which a plug element provided in relation to the motor vehicle, in addition to the motor vehicle and thus in addition to the plug device 10, is provided, for example in the form of a plug element

Charging plug or plug can be connected at least electrically and preferably also mechanically. The plug is part of a

vehicle-external and thus external to the motor vehicle charging infrastructure, which can be arranged in an environment of the motor vehicle. About the

Charging infrastructure can be external to the motor vehicle, for example

Provide energy source, in particular an external power network with respect to the motor vehicle, electrical energy. The electrical energy provided by the energy source can be connected to the charging infrastructure and the plug device 10

Motor vehicle and in particular be transferred to the energy storage device, thereby charging the energy storage device.

The plug device 10 has a first plug field 12, which has first electrical contacts 14a, 14b for transmitting electrical current for charging the

Has energy storage. The first plug-in field 12 can also have further contacts 16a-c, for example at least one or at least two of the contacts 16a-c being used during the charging of the energy store in order to exchange data between the motor vehicle and the charging infrastructure. At least one of the contacts 16a-c is, for example, an earth or a ground. In particular, the first contacts 14a, 14b are for transmitting alternating current for charging the

Energy storage formed so that the contacts 14a, 14b are preferably so-called AC contacts. The contacts 14a, 14b are thus used for an AC charging, also referred to as AC charging, in the context of which the energy store is charged with the aid of alternating current, which flows, for example, through the contacts 14a, 14b and is therefore transmitted by means of the contacts 14a, 14b . The plug-in device 10 also has a second plug-in field 18, which has second electrical contacts 20a, 20b for transmitting direct current for charging the energy store. The contacts 20a, 20b are thus used to lead, conduct and thus transmit direct current, also called DC current, for charging the energy store. If the energy store is thus charged via the contacts 20a, 20b, direct current flows through the contacts 20a, 20b. In order to be able to charge the energy store as required and with high charging currents, the plug-in device 10 has a third plug-in field 22, which has third electrical contacts 24a, 24b, by means of which direct current for charging the energy store can be transmitted in parallel with the contacts 20a, 20b. The plug-in device 10 also has a fourth plug-in field 26 which has fourth contacts 28a, 28b, by means of which direct current for charging the energy store can be transmitted parallel to the second contacts 20a, 20b and parallel to the third contacts 24a, 24b. In the first

In addition, the plug-in device 10 has a fifth plug-in field 30, which has fifth contacts 32a, 32b, by means of which direct current is parallel to the second contacts 20a, 20b, parallel to the third contacts 24a, 24b and parallel to the fourth contacts 28a, 28b is transferable for charging the energy store. If the energy store is thus charged by means of the plug-in device 10, by means of direct current and thereby by means of the plug-in fields 18, 22, 26 and 30, direct current flows for charging the energy store simultaneously or in parallel through the contacts 20a, 20b, 24a, 24b, 28a, 28b and 32a, 32b. This enables a particularly high value of the direct current used as the charging current to be realized, so that the energy store can be charged with a particularly high amount of electrical energy in a particularly short time even if the energy store has a particularly high storage capacity. In particular, 10 direct currents from 400 A to 500 A per patch panel can be charged via the respective contact pair by means of the plug-in device, and thus a total charging current of 1600 A or 2000 A for charging the energy store can be realized.

1 that the plug-in areas 18, 22, 26 and 30 have the same external shape. Thus, for example, a plug which is designed such that the plug can be connected to only one of the plug-in areas 18, 22, 26 and 30 with respect to the plug-in areas 18, 22, 26 and 30, either either with the plug-in area 18 or with the Patch panel 22 or with the patch panel 26 or with the patch panel 30 can be electrically connected. The patch panels 12 and 18 are formed, for example, by a first module 34. The patch panel 22 is formed, for example, by a second module 36. The patch panel 26 is formed, for example, by a third module 38, and the patch panel 30 is formed, for example, by a fourth module 40. The modules 34, 36, 38 and 40 are designed, for example, as components which are formed separately from one another and which are connected to one another in a non-detachable or preferably reversibly detachable manner. It is provided, for example, that the modules 36, 38 and 40 are attached to the first module 34 in a reversibly detachable manner, so that the respective module 36, 38

or 40 can be detached from the first module 34, while the other modules 36, 38 and 40 remain held on the first module 34. For this purpose, modules 34, 36, 38 and 40 have, for example, respective ones

Connecting devices via which the modules 34, 36, 38 and 40 can be reversibly connected to one another.

As an alternative to this, it is conceivable that the plug-in field 12 is formed by the first module 34 and the plug-in field 18 by a further module, it being possible for the further module to be formed separately from the respective other modules 34, 36, 38 and 40. Modules 34,

36, 38 and 40 are, for example, non-detachably or reversibly detachably connected to the further module which forms the plug-in area 18. Furthermore, for example, the modules 34, 36, 38 and 40 are arranged in the circumferential direction of the further module evenly distributed over its circumference.

In the first embodiment shown in FIG. 1, a module 36 is arranged to the left of the module 34 in relation to the image plane of FIG. 1, and the module 38 is arranged to the right of the module 34. The module 40 is arranged below the module 38. The first patch panel 12 is preferably of type 1 according to the IEC 62196 standard

educated. In the first embodiment, the patch panels 12 and 18 form a combo-1 connector in accordance with the IEC 62196 standard.

Fig. 2 shows a second embodiment of the plug device 10. In the second

In one embodiment, the connector panel 12 is designed as a type 2 in accordance with the IEC 62196 standard, the connector panels 12 and 18 in the second embodiment forming a combos connector in accordance with the IEC 62196 standard. The patch panels 18, 22, 26 and 30 have the same outer shape. The plug-in panels 22, 26 and 30 are arranged, for example, as a block laterally next to the plug-in panels 12 and 18, in particular next to the module 34 having the plug-in panels 12 and 18. The plug-in panels 22, 26 and 30 can be designed as respective modules which are formed separately from one another, or the Patch panels 22, 26 and 30 are formed by a common module, which is, for example, a module formed separately from module 34.

Finally, FIG. 3 shows a third embodiment of the plug-in device 10. As in the first embodiment, in the third embodiment the plug-in fields 12 and 18 form a combo-1 plug in accordance with the IEC 62196 standard. As in the second

In the third embodiment, the patch panels 22, 26 and 30 are arranged as a block laterally next to the module 34 or laterally next to the patch panels 12 and 18.
