Description

The invention relates to the technical field of transport systems. In particular, the present invention relates to a connector, a method for closing an opening in a connector and means of transport.

Various options are available for charging electrically powered vehicles. It is divided between home charging, public charging, AC (alternating current) or alternating current charging, DC (direct current) or direct current charging, high-voltage charging or high-power charging (HPC), inductive charging and exchange distinguished from whole batteries. These charging options can be found in various forms in individual households, in companies, gas stations and/or shopping centers.

These are rigid solutions with fixed charging points or mobile solutions in which the battery is replaced. However, a mixed form between stationary loading and mobile loading cannot be found.

The pamphlet WO 2011/104609 A1 relates to an inlet arrangement in which drainage holes are provided.

The pamphlet U.S. 8,770,648 B2 relates to a device for receiving a container for a charging socket in a motor vehicle.

The pamphlet US 10,399,453 B2 describes a system for controlling a DC-DC converter for a vehicle.

The object of the present invention is to create an effective supply concept for an electrically operated means of transport.

The invention results from the features of the independent claims. Advantageous developments and refinements are the subject matter of the dependent claims. Further features, possible applications and advantages of the invention result from the following description and the explanation of exemplary embodiments of the invention which are illustrated in the figures.

According to one aspect of the present invention, a plug-in device for connecting a charging cable is specified, which has a connection housing with a connection wall, at least one pin, at least one connection cable and an additional cable.

The at least one pin is aligned essentially parallel to the connection wall in order to enable good guidance of a complementary component, for example a socket or a plug. The at least one connection cable is connected to the at least one pin and the at least one connection cable leads away from the connection housing, for example to a vehicle battery.

The alignment of the pin essentially parallel to the connection wall enables good guidance when coupled to a correspondingly designed plug and/or socket. A pin may be an elongated object made of conductive material to conduct electricity.

The at least one pin is accessible via an opening which is essentially formed by the connection wall. The auxiliary cable is connected to the connection cable, for example by means of an electrical parallel circuit, and the auxiliary cable also leads away from the connection housing.

So it may be possible to relocate pins that are essentially only accessible from the outside into a vehicle interior, for example to connect an additional battery.

The additional cable may be able to be moved flexibly, so that, for example, it is easier to lay it in a vehicle interior up to a trunk.

The object is achieved with the plug-in device in that the additional cable has an additional connection for coupling to an energy store. This additional connection, for example a socket or a plug, can be used to flexibly connect and disconnect an additional battery, for example, in order to provide an additional energy supply to the vehicle battery.

It should be noted that the terms battery and accumulator are essentially used synonymously as an exemplary embodiment of an energy store, unless a distinction is specifically pointed out.

The additional cable can be used to charge in two ways in the EV (Electrical Vehicle). The plug-in device may enable this charging in two ways, i.e. either from the inside or the outside, or both.

It may be understood as an aspect of the present invention that the connector as a vehicle-side charging socket for a plug is used in an electric vehicle and has a further charging socket in the form of the additional connection for the use of an additional battery and/or an additional battery that may be carried in the trunk, which can be led away in the direction of the trunk of a vehicle and hidden behind the lining of the trunk, and so on establish a direct cable connection to the additional battery and be able to use it to charge the vehicle battery. The flexibility may be achieved by creating a reserve energy supply based on the principle of a power bank, which can be switched on if necessary.

In one example, access to the primary charging socket is blocked when using the internal charging socket or the auxiliary connection. The charging device that is used for external or on-board charging and/or the charging socket that is essentially formed by the connection housing may be referred to as the primary charging socket.

The coupling by means of the additional connection may provide an easy option for replacing a spare battery that can be carried in a trunk.

A portable auxiliary battery connected to the auxiliary port can be used arbitrarily as a backup for the main battery. In this case, it is not necessary to create a complicated connection to the existing external charging socket of the electric vehicle. The attachment of a further charging cable to the external charging socket, which then has to be laid loosely in the trunk, can be avoided, also whether there is a plug connection on the additional cable or not.

The already provided additional cable of the plug device according to the invention may avoid that the protection for changing from external charging to charging by means of an additional battery or power bank, which can be used as reserve energy, is regulated by an additionally attached electronics be connected in a simple electrical parallel circuit, for example by both being connected to the same pin.

Replacing a vehicle-mounted charging socket can be avoided by attaching an additional cable. This can reduce conversion costs.

The plug device according to the invention offers the possibility of leading the charging socket directly into the trunk in order to be able to use an additional battery that may be carried there as a backup energy supply as a reserve means for power supply, for example if an incorrect battery range has been determined due to an incorrect charge level display.

The plug device described makes it possible to provide an on-board charging socket in order to charge the vehicle battery both from the outside, usually when parked at a charging point, and from the trunk when driving, via the reserve battery. Or in other words, this may mean that the vehicle battery essentially cannot distinguish between being charged from the outside and from the inside. However, the onboard battery can provide great flexibility in charging the vehicle battery. Additional batteries charged at gas stations could be provided, for example.

The plug-in device advantageously has a further additional cable, the further additional cable also being connected to the connection cable, for example by means of a parallel connection. The additional additional cable leads away from the connection housing and has an additional additional connection for coupling an energy store.

The further additional cable can be provided if different types of power supply are to be used, for example AC or DC. In another example, however, an AC-DC and/or DC-AC converter may be provided, which adapts the different types of voltage and/or current to one another.

According to another aspect of the present invention, the connection housing with the at least one pin, the additional connection and/or the further additional connection is designed as a plug and/or as a socket.

Vehicle-side charging points are often designed as sockets or charging sockets. However, this may not rule out installing a plug in a correspondingly fixed manner in a vehicle.

According to a further aspect of the present invention, the plug is designed as a DC plug and/or as an AC plug. If the additional connection is designed as a socket, the socket can be designed as a direct current socket and/or as an alternating current socket.

Various standards for plug and/or socket types have been established worldwide. These are usually permanently installed in the vehicle. Then the manufacturers have mostly provided locally present EV (Electro Vehicle) charging solutions. However, the preparation of mobile and flexible charging solutions was overlooked.

As an AC charging connector, there are, for example, the plug types J 1772 Type 1 from North America and the type J1772 Type 1 from Japan. The Mennekes Type 2 is used in the EU and the GB/T type has prevailed in China.

The plug type manufactured by Tesla is essentially represented in all markets and can be used for both AC and DC charging.

Types CCS1, CHAdeMO, CCS2 and GB/T are available as DC charging connectors.

According to a further aspect of the present invention, the connection housing has an aperture. The panel is designed to close the opening through which the at least one pin is accessible.

Closing the opening may indicate that charging is taking place via the additional battery. In addition, the closure may prevent a user from touching the pins and/or connecting an external charging cable while charging from the spare battery.

According to another aspect of the present invention, the movement of the bezel is coupled or related to at least one of the auxiliary port and the further auxiliary port.

The coupling of a state of the additional connection and the further additional connection with a movement and/or a degree of opening of the screen may ensure automatic opening and closing of the opening. In other words, an operator need not worry about opening and/or closing the shutter.

According to another aspect of the present invention, the coupling of the movement of the panel is designed as a mechanical coupling and/or an electrical coupling.

For example, a coupling, connection or a coupling state of the energy store with the additional connection or with the further additional connection can be detected by means of electronics and transmitted to the cover and/or the plug-in device via a vehicle bus, so that the opening of the cover changes according to coupling state. For example, the cover is closed when coupled, while the cover is open when uncoupled and is available, for example, to accommodate a charging cable.

In another example, a mechanical coupling may be provided between the panel and the additional plug or another additional plug. A lever and/or snapper can be integrated into the additional plug, which is actuated and adjusts the opening of the aperture via a mechanical coupling device such as a Bowden cable.

According to yet another aspect of the present invention, the plug-and-socket device has at least one energy store, the at least one energy store being coupled to at least one of the additional connection and the further additional connection.

According to a further aspect of the present invention, a method for closing an opening in a plug-in device is described, which has a connection housing, a connection cable and an additional cable.

The object is achieved in that the coupling of an energy store with an additional connection of the additional cable is detected by means of the method and the opening in the connection housing is closed.

The method also takes place in a correspondingly analogous manner when decoupling the energy store and the additional connection of the additional cable, with essentially opposite actions than when coupling. If this decoupling is detected, the panel is opened and the at least one pin is again accessible from the outside, for example to connect an external charging cable.

In other words, closing an unused connection and/or an unused socket, for example the connection housing with the at least one pin, the additional connection and/or the further additional connection, may also work in the opposite case. This means, for example, that the device is set up in such a way that when an external charging cable is plugged into the connection housing, it prevents an additional battery from being able to be connected to the additional connection, in particular that the pins are protected against contact.

In addition to mechanical measures, electrical measures can also be provided in order to establish locking and/or protection against contact.

For example, it may be possible to replace an unused pin with suitable electrical Measures to make touch-safe, for example by coupling from the outside to the inside via an electrical switch. The locking would then have to be ensured electronically. These electrical and/or electromechanical methods can be used in combination with mechanical methods.

In one example, a regulating device and/or a control device could be provided in order to enable the energy store and/or the additional battery to also be charged from the external socket. In one example, such a regulating and/or control device may be set up to monitor that the vehicle battery is charged first and then, if the vehicle battery is full, the additional battery is also charged. In such a case, an interlock could be unnecessary or overridden, or appropriately electrically controlled to account for the type of load. It may be prevented that freely accessible pins are present.

In another example, the plug-in device may also be set up in such a way that the additional battery can also be charged from the battery permanently installed in the vehicle, for example to provide a third party with an energy reserve from its own battery in the vehicle if an external charging option is not available. For example, a jump start, an electrical reserve canister and/or a figurative blood donation can be provided for a third party who acts independently of their own means of transport.

In one example, the screen may be implemented as a lamella screen, as a slit screen, as a lockable sliding door and/or as a lockable flap.

According to another aspect of the present invention, there is provided a program element which, when executed by a processor, performs the method of sealing an opening in a connector.

The method may be carried out, for example, by an on-board computer, in particular by a closed-loop and/or open-loop control device.

According to yet another aspect of the present invention, there is provided a computer-readable storage medium storing a program which, when executed by a processor, performs the method of sealing an opening in a connector.

As a computer-readable storage medium, a floppy disk, a hard disk, a USB (Universal Serial Bus) storage device, a RAM (Random Access Memory), a ROM (Read Only Memory), or an EPROM (Erasable Programmable Read Only Memory) may be used. An ASIC (application-specific integrated circuit) or an FPGA (field-programmable gate array) can also be used as a storage medium, as can SSD (solid-state drive) technology or a flash-based storage medium. A web server or a cloud can also be used as a storage medium. A computer-readable storage medium may also be viewed as a communications network, such as the Internet, which may allow program code to be downloaded. A radio-based network technology and/or a wired network technology can be used.

According to one aspect of the present invention, a means of transport with a plug-in device is specified.

Further advantages, features and details result from the following description, in which at least one exemplary embodiment is described in detail-if necessary with reference to the drawing. Described and/or illustrated features can form the subject of the invention on their own or in any meaningful combination, possibly also independently of the claims, and in particular can also be the subject of one or more separate applications. Identical, similar and/or functionally identical parts are provided with the same reference symbols.

1 shows a connector 100 for connecting a charging cable (not shown in 1 ), For example, a charging point, with a coupled energy supply according to an exemplary embodiment of the present invention.

The plug device 100 has a connection housing 101 with a connection wall. In 1 although not shown, the plug-in device 100 has at least one pin 105 which is connected to the at least one connection cable 102. in the in 1 In the example shown, there is more than a single pin, so that a whole bundle of cables 102, 103 leads away from the plug-in device 100. The at least one pin is accessible via an opening 104, which is essentially formed by the connection wall. The connection cable 102 leads to an on-board battery or vehicle battery (not shown in 1 ).

Furthermore, an additional cable 103 and another additional cable 103a are shown, the additional cable 103 and the additional additional cable 103a being connected to the connection cable 102, for example by both cables 102, 103 or, in the case of a cable bundle, corresponding individual lines, are each connected to a corresponding pin. The same may apply analogously to the further additional cable 103a. In this manner of electrical interconnection, a parallel connection may arise, for example if corresponding cable ends that belong together are interconnected at a pin 105 .

The additional cable 103 has an additional connection 107 for coupling to an energy store 106 . The additional connection 107 is in the example 1 designed as an AC charging plug.

The further additional cable 103a has a further additional connection 107a for coupling to an energy store 106, but is not coupled to it. The other additional connection 107a is in the example 1 designed as a DC charging plug.

Due to corresponding coupling devices 107, 107a, for example additional connection 107 or further additional connection 107a, the energy store 106 can be designed as a replaceable rechargeable battery 106 or replaceable battery 106, which can be easily removed from the vehicle due to its replaceability and can be charged at a separate charging device. for example overnight.

A cable 108 is also arranged between the additional connection 107 and leads to the replaceable rechargeable battery 106 or energy store 106 .

the 2 shows a schematic plan view of a means of transport 200 with a built-in plug-in device 100 according to an exemplary embodiment of the present invention.

The energy store 106, the battery 106 or the rechargeable battery 106 can be accommodated in a trunk of the means of transport.

A connection to the permanently installed vehicle battery 201, which serves as a vehicle energy store 201, is established via the connecting chain starting from the replaceable battery 106 via the cable 108, pin 105 in the connection housing 101 and further via the connection cable 102.

A plug device 101 is often installed or positioned at different, non-standard installation positions in the vehicle. A charging plug and/or a charging socket can be arranged at the front, on the side or at the rear of the vehicle. In most cases, however, they create an interface for transferring energy into the vehicle interior, for example to a vehicle battery 201 .

Due to the flexibility due to the detachability of an additional battery 106, a very mobile charging system can be created. The auxiliary battery 106 can be installed and used as needed, for example when the range of an EV is to be increased. Temporary use to save weight is also possible.

A two-way charging system 100 can be created in which the vehicle battery 201 is charged via the at least one pin 105, for example a charging plug. Since an existing charging connection is essentially extended by the additional battery, the additional costs are small compared to the benefit they bring. The BOM (Bill of Material) essentially does not need to be expanded. Likewise, there is essentially no impact on the architecture. The charging performance with the additional battery 106 and without the additional battery 106 is essentially unaffected by the additional battery 106 with regard to power, speed and losses. The installation of Additional batteries 106 in the trunk allow for easy connectivity and easy access to the additional battery 106. The additional connection and the further additional connection allow easy retrofitting, so that there is a good chance that this form of capacity expansion can establish itself as a standard architecture.

If necessary, new space options can be created by changing the arrangement in the trunk, despite additional space consumption by the additional battery 106. The additional battery can be used to charge the EV flexibly when required if a mobile charging system with low capacity is created should be, which can be easily carried in the trunk. Using the additional battery, it can also be used to counter the fear of some EV users who fear being stuck on the road due to low onboard charging capacity.

The trunk may be easily accessible to accommodate the extra battery. For special excursions, such as weekend trips or energy-intensive wintertime excursions, charged auxiliary storage 106 could be offered as a service. The additional battery 106 can be regarded as a range increaser.

The plug-in device 101 or charging device 101 for a battery 201 of a motor vehicle 200 has a vehicle-side charging socket with an opening 104, which has two further connection options 107, 107a, which make it possible to connect a replaceable battery 106 located in the trunk. The connection options include an AC 107 and a DC connection 107a, which can be reached from the trunk. Motor vehicle 200 also has, in particular, at least one electric drive.

In one example, a charging device 101 for a battery 201 of a motor vehicle 200 has a replaceable battery 106 placed in the trunk. The charging plug 101 on the vehicle side offers the possibility of charging the main battery 201 with AC 103 or with DC 103a via the two additional charging cables 103, 103a. The replaceable battery 106 can be connected to the additional connections 107, 107a, as required, in order to charge the battery 201 on the vehicle side via the cable 102.

The electrical wiring essentially provides for a pure parallel connection of the connections 107, 107a and the at least one pin 105 inside and outside. In other words, this may mean that the contacts routed to the outside in the form of pins 105 are interconnected in parallel with the additional cables 103, 103a and the connecting cable 102. Thus, the charging connection 101, 104, 105 may lead from the rigid outer arrangement to a connection option in the trunk that can be moved by means of flexible connection lines 103, 103a, which enables the additional battery 106 to be installed easily.

However, precautionary measures must also be taken, since the parallel connection of the additional battery 106 and the vehicle battery 201 could result in the at least one pin 105 carrying a dangerous voltage.

Therefore, an aperture is provided.

3 shows a perspective side view of a connection housing 101 with a panel 300 according to an exemplary embodiment of the present invention. The DC connection 107a can be configured in accordance with in 3 connection shown. Also AC-Anschulss 107.

When the rechargeable battery 106 is connected and placed in the trunk 401 , the electrical safety is ensured by the locking mechanism 300 of the external loading flap 101 . Once the removable battery 106 is connected, the loading door is locked, for example by closing a shutter or restricting a door from moving. If the battery 201 on the vehicle is to be charged at an external charging station, the replaceable battery 106 must first be disconnected from the vehicle. Only then can the tailgate 300 and/or panel 300 be unlocked. It is possible to use different variants of the screen 300 to increase security, for example a lockable flap 300 in combination with a lamella screen 300, which are arranged one behind the other.

4 shows a detail from a rear view of a trunk 401 of a means of transport 200 in which a replaceable energy store 106 is arranged according to an exemplary embodiment of the present invention.

To connect to the vehicle's external charging port 101 (not shown in 4 ), the connection to the pins 105 is passed through the trunk bushing 400 and/or the trunk lining 400 by means of a flexible additional cable 103 and flexible cable 108 in order to be brought to the replaceable battery 106. It is by means of the additional cable 103, 103a a physical range extension of the external and / or vehicle reached the charging devices, for example the at least one pin 105.

5 shows the schematic plan view of an external charging connector 101 with pins 105, 105-1, 105-2, 105-3, 105-4, 105-5 according to an exemplary embodiment of the present invention.

At the in 5 The charging connector shown is a charging connector according to the J1772 standard, viewed from the connection side. In other words, this charging connection 101 is designed as a socket with pins 105 and is integrated into the vehicle body of the means of transport 200 . A catch 501 is provided in an upper area, on which a suitable plug can engage and find support. The latch can be locked to prevent theft of the connected cable.

Pins 105 are assigned the following functions.

Pin 105-1 carries phase L1, pin 105-5 transmits a proximity signal to a proximity detector. With this signal the connection of a plug is recognized. Pin 105-3 carries the GND potential, i.e. a reference potential. Pin 105-4 transmits a control signal that is used to detect, for example, whether the charging method desired by a charging station and/or the vehicle is supported at all. Pin 105-2 carries phase L2 or neutral N.

Circuit diagram 502 shows the internal interconnection between pin 105-4 and pin 105-3. Starting from pin 105-4, a diode is used in the direction of a parallel connection of two resistors, 2.74 kΩ and 1.3 kΩ, whereby the branch with the 1.3 kΩ resistor can be switched using a switch.

the 6 shows a flow chart for a method for closing an opening 104 in a connector 100 having a connection housing, a connection cable and an additional cable according to an exemplary embodiment of the present invention.

The method starts in the idle state S600.

In state S601, the coupling of an energy store with an additional connection of the additional cable is detected.

Then, in state S602, the opening 104 in the connector housing is closed to reduce danger to the connector operator by preventing the pins 105, 105-1 . 105-2, 105-3, 105-4, 105-5 can be touched, for example by introducing a barrier and/or a screen 300.

In state S603, the process ends.

To open and/or decouple the opening 104, the method can proceed in a correspondingly analogous but possibly opposite manner. One of the main goals may be to switch free pins without touching them, either mechanically or electrically or with a combination of electrical and mechanical.
