Definitions

  • the invention relates to a system with a charging connector having a charging contact for electric and hybrid vehicles, a heat accumulator and an electrical line.
  • 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 capacity of these high-voltage batteries is limited, so they must be recharged regularly 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 equipped 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 causes it to heat 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 restricted to 50 K. This in turn leads to a maximum charging current for largely standardized connector geometries that generally cannot exceed 200 A in continuous load operation.
  • an electrical connection body which enables increased charging currents with limited heating and therefore has an increased short-time current carrying capacity.
  • an electrical connection body for a charging plug or a charging socket is proposed, wherein the electrical connection body has a first connection area for galvanic connection with a electrical energy receiver and a second connection area 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 plug connector for electric and hybrid vehicles which starts from the side of the charging station, is also well known from the prior art.
  • DE 10 2015 119 338 A1 describes, for example, that two connection points for coolant lines are arranged on a contact sleeve element of a charging plug. By means of a spiral-shaped plug-on element, coolant is guided in a circle around the contact sleeve element. The two connection points serve as inlet and outlet for the coolant, which is guided from the charging station to the charging plug.
  • EP 3 433 902 B1 likewise describes a plug connector part with cooled contact elements.
  • the supply of coolant via coolant lines to the contact elements of the charging socket connected to the charging cable is provided on the charging station side.
  • 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,

  • DE 10 2016 107 409 A1 describes a connector part for connecting to a mating connector part, which comprises a housing having a plug-in section for plugging into the mating connector part and a contact element arranged on the plug-in section for making electrical contact with 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 heat sink is in thermally conductive connection with the contact element for dissipating heat from the contact element via the heat pipe.
  • a connector part with a contact element is provided which has a high current-carrying capacity, for example for use in a charging system for charging an electric vehicle.
  • DE 20 2019 102 461 U1 describes a plug connector part for connecting to a mating connector part, comprising a housing, a plug-in section arranged on the housing for plugging into the mating connector part, an electrical contact element arranged on the plug-in section for transmitting a current between the plug connector part and the mating connector part, and a cooling element arranged on the contact element for cooling the contact element, wherein a fan device is provided for generating an air flow at the cooling element.
  • this system and the system described in DE 10 2016 107 409 A1 are very complex.
  • a system is thus provided with a charging connector for electric and hybrid vehicles having a charging contact, a heat accumulator and an electrical line, wherein the heat accumulator is connected to the charging contact is connected in a galvanic and thermally conductive manner and the electrical line is connected in a galvanic conductive manner to the heat accumulator, so that heat can be dissipated from the charging contact to the heat accumulator and a charging current can be transferred from the charging contact to the electrical line via the heat accumulator.
  • the charging contact is usually accommodated in a charging connector in such a way that one end of the charging contact, which comes into contact with the electrical cable, is cut out in the charging connector, so that precisely this end of the charging contact can come into contact with the electrical cable on a side facing the interior of the electric or hybrid vehicle, without the electrical cable having to be inserted into the charging connector itself.
  • the charging contact protrudes from the charging connector, but is not connected directly to the electrical cable, but rather to a heat storage device.
  • a heat storage device is one that is capable of absorbing and storing the heat generated during the charging process more effectively than a conventional cable. This can delay the heating of the charging connector's components.
  • this heat storage is not only used to absorb the heat generated during the charging process, but also to transmit a charging current to the electrical line.
  • the direct connection of the heat accumulator to the charging contact ensures improved heat transfer from the charging contact to the heat accumulator.
  • the charging contact is connected via the heat accumulator to the electrical line leading to the battery of the electric or hybrid vehicle.
  • the heat accumulator with the system according to the invention is arranged outside the housing in such a way that the heat generated during the charging process can be removed from the charging contact and absorbed in the heat accumulator without the heat absorbed in the heat accumulator additionally heating the charging connector.
  • the heat accumulator can be designed partly as a type of ring cable lug, which makes thermal and galvanic contact with the end of the charging contact protruding from the charging connector.
  • the electrical line can, in turn, contact the heat accumulator with another ring cable lug.

  • the housing of the heat accumulator is Silver material is sealed.

  • a phase change material is arranged in the housing, the phase transition from the solid phase to the liquid phase can be used to cool the charging contact.

  • phase transition material are materials which can give off or absorb heat or cold during their phase change depending on the respective melting point and the ambient temperature.
  • phase-change materials have an advantage in terms of heat storage density, especially at small temperature differences.
  • phase change material If a phase change material is heated and its temperature approaches the melting temperature, the heat absorbed by the phase change material is used to to complete the phase change. Therefore, no temperature increase occurs during the transformation from the solid phase to the liquid phase. Once the phase change material is completely liquid, the phase change material continues to heat up as before the phase transition.
  • phase-change material does not heat up further during the phase transition, the heating is delayed compared to heating without a phase transition. This is exploited according to the invention to keep the temperature at the charging contact, which is in thermally conductive contact with the heat storage device, as low as possible. This makes it possible to extend the time during a charging process until a critical temperature is reached, at which the charging process must be interrupted.
