摘要： A ground assembly for an inductive charging device for inductively charging a motor vehicle parked on a surface may include a base plate, a flat coil, a core arrangement, a lower hollow space, a support, and a heat conducting element. The flat coil may be arranged spaced apart from the base plate. The core arrangement may be arranged between and spaced apart from the base plate and a helically wound conductor of the flat coil. The support may be disposed between a core body of the core arrangement and the base plate, and may extend through the lower hollow space. The flat coil may include a stranded wire carrier, which may include a pressure pedestal arranged co-axially to the support. The heat conducting element may at least partially surround the pressure pedestal and may connect the stranded wire carrier with the core body in a heat-transmitting manner.

摘要： A stationary induction charging device for wireless energy transfer may include a housing base, a housing cover, a transmitting coil, at least one magnetic field conductor, and a power electronics unit. The housing base and the housing cover may define an installation space and a venting space. The transmitting coil, the magnetic field conductor, and the power electronics unit may be arranged in the installation space. The housing base may include a plurality of coolant channels through which a liquid is flowable such that the housing base forms a heat exchanger. The plurality of coolant channels may be distributed within the housing base such that a region of the housing base arranged opposite the power electronics unit and/or a region of the housing base arranged opposite the venting space has a higher coolant channel density than a region of the housing base arranged opposite the transmitting coil.

The alternately stacked plurality of first stack discs and second stack discs may form a plurality of stack disc pairs. Each of the plurality of stack disc pairs may include a first stack disc and a second stack disc. The first stack disc and the second stack disc may define a gas flow path. At least one tube body may be positioned within at least one intermediate space defined between at least a first stack disc pair of the plurality of stack disc pairs and a second stack disc pair of the plurality of stack disc pairs adjacent to the first stack disc pair in the stack direction. The at least one tube body may define a coolant flow path. The at least one first stack disc pair may be in fluid communication with the at least one second stack disc pair via at least one connecting gas flow path. A thermoelectric module having at least one thermoelectrically active element may be disposed within the at least one intermediate space between the gas flow path and the coolant flow path. The thermoelectric module may include a hot side in thermal contact with the gas flow path and a cold side in thermal contact with the coolant flow path. An inner thermal insulation having at least one thermal insulation element may be disposed within the insulation interior space. The inner thermal insulation may be constructed and arranged to thermally insulate the gas flow path relative to the coolant flow path.

摘要： A thermoelectric generator for a motor vehicle may include a plurality of first stacking disks and a plurality of second stacking disks. The plurality of first stacking disks and the plurality of second stacking disks may be alternately stacked in a stacking direction and may each be shell shaped. The alternately stacked plurality of first stacking disks and second stacking disks may form a plurality of stacking disk pairs. The plurality of stacking disk pairs may each include a first stacking disk and a second stacking disk adjacent to the first stacking disk in the stacking direction. The first stacking disk and the second stacking disk may define a gas path. At least one intermediate space may be defined between adjacent stacking disk pairs. At least one tubular body may be disposed within the at least one intermediate space and may define at least one coolant path. The gas path may be traversed by a gas having a first temperature higher than a second temperature of a coolant flow through the at least one coolant path. At least one thermoelectric module having at least one thermoelectrically active element may be interposed within the at least one intermediate space between the gas path and the at least one coolant path. The thermoelectric module may include a hot side in thermal contact with the gas path, and a cold side in thermal contact with the coolant path.

摘要： A thermoelectric module may include a metallic module housing surrounding a module interior and conductor bridges arranged therein. The module housing may include a cold side wall and a warm side wall connected to cold-side conductor bridges and warm-side conductor bridges, respectively, in a thermally conductive, electrically insulating and permanent manner. The module may also include thermoelectric elements extending between the cold-side and warm-side conductor bridges. The cold side wall may be formed from a first metal material having a first heat expansion coefficient, and the warm side wall may be formed from a second metal material having a second heat expansion coefficient distinct from the first heat expansion coefficient. At least one of the first and second metal materials may be an iron material, the wall formed from the iron material having an electrically insulating coating, including one of a glass-ceramic sol-gel, a silicon oxide, and a polysilazen coating.

摘要： An induction charging device for an electrically operated motor vehicle may include at least one charging assembly. The at least one charging assembly may include a charging coil, a ferrite assembly, a metal shielding plate, and a temperature-control assembly through which a fluid is flowable. The charging coil may be inductively couplable to a primary coil such that a motor vehicle battery is inductively chargeable. The ferrite assembly may include a plurality of rotatable ferrite plates arranged next to one another. When in a closed position, a respective ferrite plate may be arranged parallel to the charging coil and may shield the metal shielding plate from the charging coil. When in an open position, the respective ferrite plate may be arranged at an angle relative to the charging coil and may partially shield the metal shielding plate from the charging coil.

摘要： The present disclosure describes an induction charging device for a partially or fully electrically operated motor vehicle. The induction charging device includes at least one charging coil and a temperature-control assembly including a fluid pipe for a liquid fluid. The charging coil is inductively couplable to a primary coil such that a battery can be inductively charged in the motor vehicle. The charging coil is heat-transmittingly connected to the fluid pipe such that the waste heat from the charging coil can be transmitted to the fluid. The induction charging device further includes a metal shielding plate for shielding electromagnetic field emissions, and a ferrite assembly for directing an electromagnetic alternating field. The charging coil is arranged in the fluid pipe such that the fluid can flow around it on all sides. The charging coil is secured in the fluid pipe directly or via a retaining device.

摘要： The present invention relates to an induction charging device (1) for a vehicle charging system (2) and to a method for limiting the thermal loading of a magnetic field conductor (3) of such an induction charging device (1).
The present invention is based on the general idea of suppressing or at least reducing an impermissible thermal loading of the magnetic field conductor (3), in particular the development of impermissible temperature gradients in the magnetic field conductor (3).-

摘要： An induction charging device for an electrically operated motor vehicle includes a charging assembly having a charging coil, and a temperature-control assembly having a fluid pipe. The charging coil can be inductively coupled to a primary coil, such that a battery in the motor vehicle can be inductively charged. The charging assembly has a ferrite plate for directing the electromagnetic alternating field, which is established between the charging coil and the fluid pipe, such that waste heat from the ferrite plate and the charging coil can be transmitted to the fluid in the fluid pipe. The fluid pipe is formed by a shell-type metal shielding plate for shielding electromagnetic field emissions and a shell-type lower shell heat-conductingly in contact with the ferrite plate. The metal shielding plate and the lower shell are secured on one another in a fluid-tight manner and spaced apart from one another with a stiffening insert.
