Definitions

  • the invention relates to a charging connector for electric and hybrid vehicles, with a housing, charging contacts arranged in the housing and a heat sink.
  • Electric and hybrid vehicles have a rechargeable energy storage device, usually a high-voltage battery, which supplies energy to an electric drive motor during operation.
  • the storage capacities of these high-voltage batteries are limited, so they must be regularly recharged at a charging station.
  • the battery is charged using a charging cable provided between the charging station and the vehicle.
  • the charging cable for example in accordance with the European standard IEC 62196 Type 2, is provided with a charging plug on one side that can be plugged into a charging socket provided on the charging station, and with a charging coupling on the other side that can be connected to a charging plug installed in the electric or hybrid vehicle.
  • charging sockets, charging plugs, charging couplings and charging plugs are subsumed under the term "charging connector”.
  • Charging sockets and charging couplings have contact sleeves as charging contacts, and charging plugs and charging plugs that can be installed in electric and hybrid vehicles have contact pins as charging contacts that can be inserted into the contact sleeves.
  • a charging current flowing through the charging connector heats up due to ohmic current heat losses.
  • the heating of the charging connector is legally limited to a limit temperature increase.
  • the limit temperature increase is limited to 50 K. This in turn leads to a maximum charging current for mostly standardized connector geometries that generally cannot be greater than 200 A in continuous load operation.
  • the object is to provide an electrical connection body that enables increased charging currents with limited heating and therefore has an increased short-term current carrying capacity.
  • This object is to be achieved by providing an electrical connection body for a charging plug or a charging socket, wherein the electrical connection connection body has a first connection region for galvanic connection to an electrical energy receiver and a second connection region for galvanic connection to an electrical energy source, wherein the electrical connection body is designed such that it has a cooling fluid channel formed in the electrical connection body, wherein the cooling fluid channel of the electrical connection body is fluidly connected to a cooling fluid source which is arranged in a charging station.
  • Cooling of a charging connector for electric and hybrid vehicles is also well known from the prior art.
  • DE 10 2015 119 338 A1 describes that two connection points for coolant lines are arranged on a contact sleeve element of a charging plug. Coolant is guided in a circle around the contact sleeve element by means of a spiral-shaped plug-in element. The two connection points serve as inlets and outlets for the coolant, which is guided from the charging station to the charging plug.
  • EP 3 433 902 B1 also describes a connector part with cooled contact elements.
  • the charging station side provides for the supply of coolant via coolant lines to the contact elements of the charging socket connected to the charging cable.
  • the coolant is a fluid which is guided perpendicular to the contact element into the hollowed-out contact element and flows back inside the contact element.
  • 10 2016 105 361 B4 also describes a connector part with a cooled contact element, whereby here too a coolant is supplied via coolant lines to the contact elements of a charging socket connected to the charging cable on the charging station side. Guide elements are arranged on the contact elements, which are intended to ensure that the coolant in the form of compressed air flows around the contact elements.
  • DE 10 2016 107 409 A1 describes a plug connector part for connecting to a mating connector part, which comprises a housing that has a plug section for plugging into the mating connector part and a contact element arranged on the plug section for electrically contacting an associated mating contact element of the mating connector part.
  • a heat pipe connected to the contact element and a heat sink arranged in the housing are provided, which is in thermally conductive connection with the contact element for dissipating heat from the contact element via the heat pipe.
  • a plug-in connector part with a contact element is provided which can have a high current carrying capacity, for example for use in a charging system for charging an electric vehicle.

  • a hybrid component means a component that has at least two materials.
  • a heat sink is understood to be a body that ensures that, in the charging connector according to the invention, the heat generated in the charging contact is dissipated, absorbed in the heat sink and released into the housing and/or the environment. The heat dissipation away from the charging contact to which the heat sink is connected is better than without the heat sink. Installing the heat sink therefore improves the ability to dissipate heat generated on or in the charging contact. Furthermore, the heat sink is an additional element of the charging connector, i.e. it is separate and different from the housing.
  • the direct contact of the charging contact with the plastic material helps to ensure that the ceramic element has the most advantageous thermal contact with the charging contact.
  • Ceramic is a porous, difficult to deform material that is only partially suitable for making form-fitting contact with a body in such a way that Air as a thermal transmission path can be practically excluded. This is especially true when taking into account the respective manufacturing tolerances.
  • the heat sink as a hybrid component made of a ceramic element and a plastic material applied to at least part of the surface of the ceramic element now makes it possible to form-fit the charging contact with the plastic material in such a way that heat exchange in the form of convection can be practically avoided.

  • Heat-conducting plastic has the advantageous property of being electrically insulating.
  • the choice of material for the heat-conducting element depends on the expected heat to be dissipated. Silicones have good thermal conductivity and electrical insulation.

  • the addition of ceramic particles improves the thermal conductivity of the plastic material without impairing the contact between the charging contact and the plastic material in the form of air inclusions.
  • the ceramic element can be designed in various ways.

  • the ceramic element is partially enclosed by the plastic material. This makes it possible to achieve contact with the charging contacts over as large an area as possible, while part of the surface of the ceramic element remains uncovered and the heat dissipation is thus increased.
  • the plastic material generally has a lower thermal conductivity than the ceramic element. The heat dissipation is increased because the heat does not have to be conducted through the plastic material again in order to then be dissipated by convection.
  • a charging connector of the type in question has seals for sealing against the outside.
