Description

The invention is based on an electrical conductor arrangement comprising at least one conductor profile and relates to a motor vehicle having such an electrical conductor arrangement.

Electromobility, also called e-mobility or English e-mobility, provides for the use of electric vehicles, which carry an energy storage in the form of an electric accumulator or a battery accumulator and include an electric drive, which can vary in the degree of electrification. Electromobility is currently undergoing dynamic development, in particular as a result of environmental policy objectives taking into account mobility needs in terms of sustainability, so that in the future the electrification of the powertrain in a motor vehicle will continue to increase.

The charging times of the currently used accumulator batteries or built-in battery capacities are based on the amount of energy supplied to the vehicle significantly longer than the usual with a refueling operation of an internal combustion engine at a gas station tank times. Shorter charging times are therefore desirable, especially if you want to drive with an electric vehicle on longer distances beyond the range defined by the battery capacity. The charging time decreases with the increase of charging power. The implementation of a fast charging concept requires a high electrical and thermal load capacity of the components in the charging path. It requires an electrical conductor arrangement which can transmit the required power. The charging station provides a final charging electric voltage and charging current for the battery in the vehicle. The permissible magnitude of the electrical voltage and the charging current intensity are determined by the components of the electrical path installed in the vehicle and their load capacity. An essential part of the electrical charging path are the electrical conductor arrangement from the charging socket in the motor vehicle to the accumulator battery. From the accumulator battery, at least one electrical conductor or a conductor strand consisting of electrical conductors also leads to the electric drive of the motor vehicle.

The charging time depends on the performance of the charging station as well as the technical design of the vehicle or the components of the electrical charging path in the vehicle.

From the electrical conductors and plug-in connections of electrical charging stations for electric vehicles is known that the transferable at the permissible electrical voltage electrical power is limited by the thermal capacity of the electrical lines and the plug contacts, due to the electrical contact resistance in the small-area contact point, the largest power loss density in the charging circuit. Contact heating is currently limiting the performance of fast-charging electric stations. In order to increase the transferable power liquid-cooled, flexible electrical cables and liquid-cooled plug or plug contacts are used. However, these lead to an increase in size and weight as well as a reduction in line flexibility and their handling.

In the scope of DE 11 2012 003 099 T5 , which describes a charging station for fast charging of an electric vehicle battery, among other things, a coolable power connection between the charging port and the electric battery is described.

The generic US 2012/0 181 082 A1 discloses an electrical conductor arrangement, comprising a conductor profile, wherein the conductor profile is extruded and consists of a light metal alloy and the conductor profile has a circumferentially closed channel.

Comparable proposals are in the DE 29 18 600 A1 , of the DE 603 16 980 T2 or the US Pat. No. 3,679,811 described.

The technological background includes the DE 196 03 215 A1 and the DE 11 2014 003 691 T5 ,

The invention has for its object to provide an electrical conductor assembly for a motor vehicle with a conductor profile of a solid and chemically resistant material, which is flexible in shape and length manufacturable, weight-wise advantageous and inexpensive, wherein the conductor arrangement dissipating the heat of allows the contact points and a low-loss transfer of electrical power with the required for the operation of a power electrical device or an electric drive electric currents and high electrical voltages.

A first solution to this problem is according to the invention in an electrical conductor arrangement according to the features of claim 1.

Claim 2 shows a second solution of the problem.

Advantageous embodiments and further developments of the electrical conductor arrangement are the subject of the dependent claims 3 to 13.

A motor vehicle with an electrical conductor arrangement according to the invention is the subject of claim 14.

An electrical conductor arrangement has at least one electrical conductor profile. The strip profile is extruded and consists of a light metal alloy, wherein the conductor profile has at least one circumferentially closed channel.

The electrical conductor arrangement has at least two conductor profiles which are arranged parallel to one another and which are insulated from one another by an insulator and are connected to one another.

According to the first aspect of the invention, the conductor profiles and the insulator have mutually complementary form-fitting sections which engage in one another.

According to the second aspect of the invention, the insulator has at least one duct.

Particularly preferably, the conductor profile consists of an aluminum alloy with the main component aluminum, in which the sum of other alloying elements, including admixtures and impurities caused by melting, is not more than 5.0% by mass.

In the context of the invention, an aluminum wrought alloy is considered to be a particularly advantageous material for the conductor profiles. Preferably, an aluminum wrought alloy may be used having an aluminum content of at least 99%, for example Al99.5 (EN AW-1050).

Alloys of the group 1xxx, also called pure aluminum, have a high electrical conductivity and high thermal conductivity. In addition, they are very resistant to corrosion and also weldable. Aluminum alloys of the 1xxx group are therefore particularly suitable as conductor material.

From group 6xxx the aluminum alloys EN AW-6060 or EN AW-6005 are well suited for the application provided by the invention as an extruded conductor profile.

Low-alloy 7xxx wrought aluminum alloys may also be used, such as aluminum alloy EN AW-7072.

An inventive conductor profile may have a plurality of inner channels extending over the length of the conductor profile. In this case, the ladder profile is an extruded profile with several channels delimited by inner webs. Here, the webs can extend both vertically and horizontally relative to the cross section of the conductor profile.

The channel or channels in a conductor profile are intended for carrying out a heat transfer medium and / or for the implementation of line bodies and / or tubular bodies and designed for this purpose. Conduction bodies may be, for example, supply lines or data lines. Tubular bodies may be separate conduits, for example coolant conduits or coolant tubes or heat pipes.

An essential aspect of the invention is aimed at a coolable electrical conductor arrangement. Accordingly, the or each channel are provided for the passage of a cooling medium, this is intended in particular to liquid or gaseous heat transfer media.

In an advantageous embodiment, a conductor profile has at least one curved section and in particular has a curvature in the longitudinal direction.

The arc section is bending technology, in particular stretching-bending technology or compression technology generated.

Furthermore, an inventive conductor profile on its outer surface heat transfer elements and / or stiffness-increasing profile elements. Heat exchanger elements as well as stiffness-increasing profile elements are preferably designed as ribs or webs.

Another essential aspect of the invention is an electrical conductor arrangement in which a plurality of conductor profiles are coupled to one another to form a conductor strand. In this case, straight conductor profiles coupled in series with curved, at least one arc section having conductor profiles may be added to the conductor strand. In the interconnected conductor profiles, the inner channels communicate in an appropriate manner for the passage of a heat transfer medium and / or for the implementation of pipe or tubular bodies.

The coupling of conductor profiles with one another to form a conductor strand can take place in a form-fitting and / or frictionally engaged and / or materially bonded manner. Possible, for example, plug-in solutions, in which conductor profiles have matched end portions for pluggable connection. The conductor profiles are aligned by positive fit their mating sections and additionally secured against unintentional loosening. Particularly advantageous is a cohesive bonding of the conductor profiles with each other, in which the channels are joined together medium-tight.

Such a conductor strand is provided in particular for on-board use or installation in a motor vehicle and extends from the charging socket of the motor vehicle to the energy store or an accumulator battery. Furthermore, a conductor strand can be used on the electrical path from the accumulator battery to the electric drive.

The inventive design of an electrical conductor arrangement provides that at least two conductor profiles are arranged parallel to each other.

The at least two conductor profiles are insulated from each other by an insulator and bonded to each other. In this case, in particular conductor profiles arranged parallel to one another are bound to one another by insulators configured in terms of material and geometry.

The conductor profiles and the insulator which binds the conductor profiles have mutually complementary form-fitting sections which engage in each other.

An embodiment of the electrical conductor arrangement according to the invention provides that at least two conductor profiles are bonded to one another by means of an insulator, whereby the insulator also has at least one line channel.

A channel can be closed at the end of a conductor profile by a closing element, for example a plug. In this way it is possible to close one or more channels appropriately. This takes place in an electrical conductor arrangement with a plurality of conductor profiles joined together to form a conductor strand, in each case on the last conductor profile of the conductor strand. This influences the continuity of the channel in the conductor track. Thus, the adjustment of the flow of heat transfer media is possible.

In a ladder profile also switch elements or pieces can be integrated. This allows for crossings in a conductor strand or also the branching or feeding of heat transfer media within a conductor strand or the electrical conductor arrangement formed by the conductor strand.

A further aspect of the invention provides that a conductor profile has at least one connection which communicates with a channel. Such a connection may preferably be a coolant connection.

Furthermore, the application possibilities are increased if at least one conductor profile with a contact surface for connecting a functional element is present. In this way, according to the application purpose, functional elements can be connected to a conductor profile in a conductor strand. Functional elements are, for example, electrical connection pieces or contact pieces or contact shoes, but also coolant collectors or coolant conductors as well as heat pipes.

Heat transfer media, both in the form of gas or a liquid, can both flow around the outside of the conductor arrangement or the conductor profile (s) of the conductor arrangement and also flow through the inside. A conductor profile may be at least partially, preferably at contact, end or joints, coated with a material having a low electron work function of W _e <(smaller) 7.9 × 10 ^-19 Joule, corresponding to 4.93 electron volts , Starting from the light metal or its alloy, which comprises the conductor profile, the coating has, up to the surface-applied contact material, at least one part of the layer sequence zinc, chromium, nickel, copper and / or silver. The conductor arrangement or its conductor profiles can be coated at least in regions, preferably at points not to be electrically contacted, with an electrically insulating or thermally radiating material, for example a lacquer. A conductor arrangement can also be used as a heat conductor, which dissipates the heat caused by the electric current from the lines, cables, plugs or plug contacts to a cooling surface or to a cooling device in a motor vehicle.

Due to the inner space of a conductor arrangement formed by at least one channel, in addition to the electrical potential of the conductor arrangement, electrical conductors, in particular data or control lines, protected against environmental influences, can be guided and fastened.

The conductor arrangement according to the invention is characterized by low transmission losses and has a greater efficiency and greater electrical Leistungsungs- or transmission capability. The possibility of dissipating the heat caused by the electric current from the peripheral lines and plugs to a cooling surface or a cooling device allows for a reduction in the mass of the electrical conductor arrangement. Furthermore, a reduction in the charging time of the battery in a motor vehicle via the conductor arrangement is to be expected. In particular, with a cooled conductor arrangement allows the motor vehicle-side conductor cooling an increase in the transferable electrical power.
