Description

The invention relates to a traction network distributor for an electrical vehicle electrical system for an at least partially electrically operable motor vehicle, the traction network distributor for distributing electrical energy of an energy storage device to at least a first electrical consumer of the electrical vehicle electrical system and for the electrical connection between at least one first converter for converting the electrical energy is designed for the first electrical consumer. The invention further relates to a motor vehicle with a traction network distributor.

In an at least partially electrically operated or an electrified motor vehicle, in addition to the 12-volt electrical system known from conventional motor vehicles, there is an additional electrical system, the high-voltage electrical system, which is primarily used to provide the driving function, but also as a source for this in electrified motor vehicles 12 volt electrical system is used. The source or sink of the high-voltage on-board electrical system is the electrical energy store, which can also be referred to as a high-voltage battery, and which uses a traction network distributor, which acts as a passive distribution unit, which can have contactors, for example, with all components of the high-voltage system, for example diverse Traction inverter, heater, air conditioning compressor, charger and / or DC / DC converter, is connected.

The traction network distributor is typically placed directly on the electrical energy store or is in the immediate vicinity, so that ohmic losses on the DC line are as minimal as possible. It can be provided that the electrical consumers are individually connected in a star shape to the traction network distributor or can be connected via a Y-cable, so that with low power requirements, two electrical consumers can use a cable harness to reduce the weight of the cable harness until they are divided.

According to the prior art, the traction network distributor is a distributor box which is designed as a multiple socket close to the battery without any filter device, since almost every component which is connected to the DC system has a DC-side intermediate circuit capacitor. This respective intermediate circuit capacitor of the individual electrical consumers serves to smooth the AC voltage impressed on the DC vehicle electrical system by conversion, which is limited, for example in the LV 123 standard, to +/- 8 volts under continuous load. This can ensure that no system components are damaged by interference or resonance, so that error-free operation can be made possible. This limitation to a certain voltage level also relieves the electrical energy store.

For example, the DE 10 2006 034 020 A1 a motor vehicle with an internal combustion engine, an electrical machine and power electronics, the motor vehicle being drivable by the internal combustion engine and / or the electrical machine. The power electronics module, which includes a high-voltage supply line, a DC control unit with a low-voltage output, an inverter unit that converts the DC voltage of an energy store into AC voltage for an additional unit, and a first control unit assigned to the DC control unit and / or the inverter unit educated.

Furthermore, the DE 10 2016 211 399 A1 1 a circuit arrangement for connection on the supply side to an alternating direction on an electrical machine, with a filter circuit with at least one filter stage, the filter stage having an XY interference suppression capacitor module connected between a plus path and a minus path of the inverter and a filter choke module connected in series with this, and wherein the filter choke assembly is designed with a toroidal core choke encompassing the plus path and the minus path for common-mode filtering and with a storage choke encompassing the plus path and the minus path for push-pull filtering.

The DE 10 2016 215 504 A1 discloses a method and a vehicle electrical system with an electrical energy storage device, an inverter and with at least one switching device switched by a controller, by means of which at least one phase current connection of the inverter can be connected to an inductive charging pulse connector an inductive charging secondary coil.

A disadvantage of the current state of the art is that each electrical consumer of the electrical system is individually electrically connected with its own intermediate circuit capacitor. It is therefore disadvantageous, in particular for the electrical vehicle electrical system, that an overall capacity which is too large is usually installed, as a result of which, in particular, space and weight are unnecessarily used. Furthermore, resonances can occur in the electrical on-board electrical system “uncontrolled”, which means that the intermediate circuits specified by the electrical consumers result in an impedance curve when interconnecting the electrical consumers on the traction network distributor, which contains resonance points that other electrical consumers may possibly have can damage. To move these resonance points, must current intermediate circuit capacitors of certain components are re-dimensioned, so that the intermediate circuit capacitance is sometimes larger than is necessary for the electrical consumers, so that the entire electrical system is designed to be stable.

It is an object of the present invention to provide a traction network distributor and a motor vehicle, by means of which interference within an electrical vehicle electrical system of the motor vehicle can be reliably suppressed in a reduced space.

This object is achieved by a traction network distributor and by a motor vehicle in accordance with the independent claims. Advantageous embodiments are specified in the subclaims.

One aspect of the invention relates to a traction network distributor for an electrical vehicle electrical system for an at least partially electrically operable motor vehicle, the traction network distributor for distributing electrical energy from an energy storage device to at least a first electrical consumer of the electrical vehicle electrical system and for the electrical connection between at least one first converter for converting the electrical energy for the first electrical consumer is formed.

It is provided that the traction network distributor is designed for distributing electrical energy to at least one second electrical consumer and for electrical connection to a second power converter for converting the electrical energy for the second electrical consumer, and an interference suppressor for suppressing electrical interference generated during the conversion of the first converter and / or of the second converter is designed, the interference suppression device being designed for electrical connection to the first converter and the second converter.

This makes it possible for the two electrical consumers to "share" an interference device. The total capacity in the electrical vehicle electrical system is thus smaller, since in particular the one interference suppression device can be designed as a central filter device, which contributes to AC voltage limitation on the electrical vehicle electrical system. By minimizing the total capacity, the space required in the electrical consumers can be reduced. Furthermore, there can be a cost saving, since a lower total capacity is required. Furthermore, the battery load can be reduced by more specifically adapting the filter effect. Furthermore, the compatibility of the entire electrical system is improved, since the filter in the traction network distributor is designed in such a way that no parallel resonances can restrict the function.

This means that no additional unnecessary interference suppression devices are implemented in the electrical system. In particular, this makes it possible for the traction network distributor according to the invention to suppress the interference occurring in the on-board electrical system in a space-saving manner and yet reliably.

It is preferably possible, for example, for a further electrical consumer to be designed with a further converter for converting the electrical energy for the further electrical consumer within the electrical system, and for the further electrical consumer or the further converter to be connected to the interference suppression device, so that faults, which arise in the conversion in the further electrical consumer, can also be suppressed with the interference suppression device. This makes it possible in particular for a large number of electrical consumers within the electrical system to be suppressed by means of a single interference suppression device. This in particular makes it possible for the one interference suppression device to be designed as a central filter unit within the traction network distributor.

In other words, the traction network distributor is designed to distribute the electrical energy of the electrical energy store within the electrical on-board network and at the same time to form a central filter unit, so that individual interference suppression devices, in particular individual intermediate circuit capacitors, can be dispensed with at the respective electrical consumer. In particular, this makes it possible for all electrical consumers to be connected directly to the traction network distributor in the form of a star point or via Y cables. If the traction network distributor is designed appropriately, all imprinted faults can be filtered before they damage another electrical consumer.

Furthermore, the traction network distributor according to the invention can prevent, for example, a superimposed alternating current on the electrical energy storage device from being transmitted by the power converters, which can protect the electrical energy storage device, so that in particular an increase in the service life of the electrical energy storage device is also realized can be.

A traction motor, which is in particular operated electrically, can be used as an electrical consumer, for example, within the Motor vehicle are viewed. For example, a traction inverter, a heater, an air conditioning compressor, a charger or a DC / DC converter within the electrical system can be viewed as a further electrical consumer. The traction network distributor can also be referred to as a battery control device or a battery junction box (BJB).

According to an advantageous embodiment, the traction network distributor is designed to distribute electrical energy to at least a third electrical consumer and to electrically connect to a third power converter for converting the electrical energy for the third electrical consumer, the traction network distributor having a second interference suppression device for suppressing interference from the third Has converter. In particular, this can then be the case, should, for example, different interference suppression devices be necessary due to different designs of the respective electrical consumers that the third electrical consumer is then connected to the second interference suppression device. This makes it possible for a large number of different electrical consumers to be connected to the traction network distributor, as a result of which an improved and more reliable operation of the electrical on-board electrical system can be carried out with a large number of different electrical consumers, with a plurality in particular meaning more than one. As a result, the traction network distributor can be used in a highly functional manner and can nevertheless reliably and interference-free suppress the faults of the electrical consumers, in particular the respective power converters.

It has also proven to be advantageous if the traction network distributor is designed to distribute electrical energy to at least a fourth electrical consumer and to connect it electrically to a fourth converter for converting the electrical energy for the fourth electrical consumer, the fourth converter being connected to the second Interference suppression device for interference suppression of the fourth converter is electrically connected. In other words, the fourth electrical consumer is connected to the second interference suppression device together with the third converter of the third electrical consumer. In particular, if the third electrical consumer and the fourth electrical consumer have at least substantially similar electrical properties, then the third and fourth electrical consumers can be connected to the one interference suppressor by means of the second interference suppression device and reliably the respective faults of the third converter and the fourth converter be suppressed. This makes it possible, for example, for the first electrical consumer and the second electrical consumer, which have essentially the same electrical properties, to be connected to the first interference suppression device and the third electrical consumer and the fourth electrical consumer, which have essentially the same electrical properties, are connected to the second interference suppression device. This makes it possible for different electrical consumers to be connected in a space-saving manner with a small number of interference suppression devices within the traction network distributor. This means that interference can be saved within the traction network distributor in a space-saving yet reliable manner.

It is also advantageous if the interference suppression device has at least one capacitor, in particular an intermediate circuit capacitor, for interference suppression. In particular, the capacitor can be designed as an intermediate circuit capacitance. In particular, the capacitor can then be used to reliably filter out the corresponding disturbances which arise when converting the direct current to an alternating current, so that, in particular, feedback of the disturbances to the battery or to further electrical consumers within the electrical on-board electrical system can be prevented. As a result, the interference within the electrical on-board electrical system can be suppressed in a simple manner by the traction network distributor, which enables reliable operation of the electrical on-board electrical system.

In a further advantageous embodiment, it is provided that the interference suppression device has at least one inductor for electromagnetic filtering. In particular, an electromagnetic compatibility (EMC) of the electrical system can be realized. In particular, it can be provided that the interference suppression device then has at least one capacitance or has a filter structure comprising different capacitances and the use of parasitic inductances or inductive components, so that frequency components can be filtered out in a targeted manner, which contribute to the electromagnetic compatibility. This enables highly functional and reliable operation of the on-board electrical system by means of the traction network distributor, while at the same time saving installation space.

die Werte der einzelnen Bauelemente bestimmt werden. Dadurch ist es insbesondere ermöglicht, dass durch die gezielte Anpassung der Filterwirkung eine Reduzierung der Energiespeicherbelastung realisiert werden kann.Furthermore, it has proven to be advantageous if the interference suppressor for the electrical connection to the first and / or second electrical consumer has a first ohmic resistance and a first inductance electrically connected in series in a first strand of the interference suppressor and electrically connected in parallel to the first strand has a second strand in which a second ohmic resistance, a second inductor and a capacitor are electrically connected in series. As a result, the effectiveness of the circuits, which ensure that the interference current is dissipated, can be increased by the appropriate placement of high-impedance, series-connected circuits. For example, the first ohmic resistance can have 0.5 mΩ. For example, the first inductance can have 10 μH. For example, the second ohmic resistance can have 1 mΩ. For example, the second inductance can have 5 nH. For example, the capacitor can have 6µF. In particular, it can be provided that the high-impedance interference suppression device is designed in such a way that a predetermined frequency is kept away from interference from the electrical energy store. In particular, using the formula: $$f_{Filter}=\frac{1}{2\pi \sqrt{LC}}$$

the values of the individual components are determined. This makes it possible, in particular, for a reduction in the energy storage load to be achieved by the targeted adaptation of the filter effect.

It is also advantageous if the traction network distributor has a third interference suppression device which is electrically connected to at least the interference suppression device. In particular, a large number of high-impedance interference suppression devices can thereby be electrically connected in each path of the traction network distributor to an electrical consumer. As a result, a large number of different frequencies of the electrical consumers can be kept away from the electrical energy store by the traction network distributor, which enables improved operation of the electrical system.

Furthermore, it has proven to be advantageous if the traction network distributor has at least one first plug contact for connecting the at least first electrical consumer and has at least one second plug contact for connecting the at least second electrical consumer, the first plug contact and the second plug contact being electrically connected to the interference suppression device are. This makes it possible in a simple manner that the first electrical consumer and the second electrical consumer can be electrically coupled to the traction network distributor. In particular, the respective plug contact can then be electrically connected to the one interference suppression device. In particular, it can be provided that, for example, a second interference suppression device should be provided that the further plug contacts are then connected to the second interference suppression device. In particular, it is realized in a simple manner that the electrical coupling to the interference suppression device is already carried out by simply plugging the first electrical consumer and the second electrical consumer into the traction network distributor. This allows the improved operation of the electrical system to be implemented in a simple manner.

It is also advantageous if the traction network distributor has a housing and the interference suppression device is arranged in the housing. This makes it possible, for example, for the traction network distributor to be placed directly on the electrical energy storage device, which can be designed in particular as a high-voltage battery, the interference suppression device then already being connected to the electrical energy storage device. As a result, the interference suppression device can already be connected to the electrical energy storage device in a reduced-effort and space-saving manner, so that interference suppression can be carried out in a simple manner within the electrical on-board electrical system.

According to a further advantageous embodiment, the traction network distributor is designed to distribute electrical energy from a high-voltage energy store. In particular, for example, the motor vehicle can then be provided as a purely electrically operated motor vehicle. The electrical energy storage device is then designed in particular as a high-voltage battery. For example, the electrical energy storage device can then provide a voltage of 400 volts. This makes it possible for the electrical on-board electrical system to operate, for example, an electric traction motor, the coupling of the electrical consumers to the one traction network distributor with the one interference suppression device providing a simple and yet reliable electrical on-board electrical system for suppressing interference with reduced installation space.

Another aspect of the invention relates to a motor vehicle with a traction network distributor according to the preceding aspect. The motor vehicle is designed in particular as a passenger car.

The invention also includes further developments of the motor vehicle which have features such as have already been described in connection with the further developments of the traction network distributor according to the invention. For this reason, the corresponding developments of the motor vehicle according to the invention are not described again here.
