Definitions

  • the invention relates to a system with a charging connector for electric and hybrid vehicles, wherein the charging connector has a housing, charging contacts arranged in the housing for contacting corresponding charging contacts of a corresponding charging connector and a cooling element which is coupled to at least one of the charging contacts in such a way that the charging contact can be cooled by means of the cooling element.
  • Electric and hybrid vehicles have a rechargeable energy storage device, usually a high-voltage battery, which provides energy to an electric drive motor during ferry operation.
  • the storage capacities of these high-voltage batteries are limited, so they have to be recharged regularly at a charging station.
  • the battery is charged via a charging cable provided between the charging station and the vehicle, whereby the charging cable, for example in accordance with the European standard IEC 62196 Type 2, has a charging plug on one side that can be plugged into a charging socket provided on the charging station, and on the other side is provided with a charging coupling that can be connected to a charging plug installed in the electric and hybrid vehicle.
  • charging sockets, charging plugs, charging couplings and charging plugs are subsumed under the term “charging connectors”.
  • Charging sockets and charging couplings have contact sleeves as charging contacts and charging plugs as well as 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 limited to a limit temperature increase.
  • the limit temperature increase is limited to 50 K. In the case of largely standardized connector geometries, this in turn leads to a maximum charging current that generally cannot exceed 200 A in continuous load operation.
  • higher charging currents are necessary over limited periods of time in order to charge the battery in the desired short time. This can lead to temporary heating of the charging connectors that exceeds the limit temperature increase.
  • the cable cross-section of the electrical connector bodies cannot be increased arbitrarily, since the connector geometries are standardized and, in addition, the electrical connector bodies should use as little conductive material as possible, usually copper.
  • the task is to be solved 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, the electrical connection body having a first connection area for galvanic connection to an electrical energy receiver and a second connection area for galvanic connection to a
  • the electrical connection body is designed such that it has a cooling fluid channel formed in the electrical connection body, the cooling fluid channel of the electrical connection body being 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 using 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.
  • a coolant is supplied via coolant lines to the contact elements of the charging coupling connected to the charging cable on the charging station side.
  • a fluid is provided as the coolant, 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, on the charging station side, the supply of a coolant via coolant lines to the contact elements of a charging socket connected to the charging cable is provided. Guide elements are arranged on the contact elements, which allow the flow around the contact elements by the coolant in the form of compressed air.
  • the object of the present invention is to enable charging of a battery of an electric or hybrid vehicle with high currents over a longer period of time.
  • a system is thus provided with a charging connector for electric and hybrid vehicles and a control unit, wherein the charging connector has a housing, charging contacts arranged in the housing for contacting corresponding charging contacts of a corresponding charging connector and a cooling element which is coupled to at least one of the charging contacts in such a way that the charging contact can be cooled by means of the cooling element, the cooling element is connected to the control unit so that the cooling function of the cooling element can be controlled by means of the control unit, and the control unit is configured to activate the cooling function of the cooling element at a time outside of a charging process.
  • the plug face has contact sleeves, and vice versa.
  • the set of charging connector according to the invention and corresponding charging connector can therefore be plugged together.
  • a corresponding charging connector is also referred to when the plug faces in the aforementioned sense only partially correspond, i.e. the corresponding charging connector, for example, does not have all the contacts that are present in the charging connector according to the invention, but the existing contacts of the corresponding charging connector correspond to the charging connector according to the invention in terms of the plug face, so that the charging connector according to the invention and the corresponding charging connector can also be plugged together in this case.
  • Such a case exists, for example, in the case of a charging coupling for direct current charging that is connected to a charging cable in accordance with the European standard IEC 62196 Type 2.
  • a charging coupling can be inserted into a charging plug that is installed in the body of an electric or hybrid vehicle and is suitable for alternating current charging and for direct current charging , whereby only the communication contacts and the protective contact are present in the AC connector face of the DC charging coupling, but no contacts for outer conductors and a center conductor for AC charging.
  • a cooling element is understood to be an element which results in active cooling of the charging contacts in the system according to the invention comprising a charging connector and a control unit by the
  • Cooling element is brought about.
  • the charging contacts of the charging connector according to the invention are cooled at a time outside of the charging process, so that the charging contacts have a temperature that is lower than the ambient temperature when the charging process begins.
  • the maximum permissible limit temperature is reached later when charging with higher charging currents.
  • the system according to the invention enables a longer-lasting charging process with higher charging currents.
  • the control unit can be connected, for example, to communication contacts of the charging connector, so that a charging process can be registered using the communication contacts. Likewise, the control unit can be connected to the charging contacts for detecting a charging process.
  • the control unit is designed to cool the charging contacts only at a time outside of a charging process. It is possible for the control unit to be arranged in the charging connector in order to offer a more compact design of the system according to the invention. In particular, however, the control unit can also be arranged outside the charging connector.
  • the invention also serves to bridge the period at the beginning of a charging process in which cooling from the charging station must first start and is therefore not yet effectively available for the charging contacts of the charging connector according to the invention.
  • the cooling element is thermally coupled to the charging contacts, so that the charging contacts can be cooled efficiently.
  • the cooling element particularly preferably contacts the charging contact directly, i.e. without electrical insulation.
  • the cooling element can also be provided with heat pipes that enable a thermal connection to the charging contacts. Solid material pipes that have high thermal conductivity are preferably used as heat pipes.
  • the cooling element can be coupled to the charging contacts using a heat-conducting paste.
  • the time outside of a charging process is a time immediately before a currently planned charging process.
  • the cooling capacity of the cooling element is known, so that the minimum achievable temperature of the charging contacts in relation to the ambient temperature is also known.
  • the minimum achievable temperature is the lowest possible temperature that can be achieved taking into account the ambient temperature and the cooling capacity. For more efficient cooling, it can therefore be provided that the cooling starts at a certain time before a planned charging process, so that the charging contacts have the minimum achievable temperature when the charging process begins.
  • the cooling element can be formed in different ways. According to a preferred development of the invention, however, it is provided that the cooling element is a Peltier element.
  • a Peltier element is an electrothermal converter that creates a temperature difference based on the Peltier effect when current flows through it.
  • Peltier elements can be used for both cooling and heating. In the present case they are used for cooling. Peltier elements are therefore cooling elements that do not require any fluid connections to the charging contacts.
  • the temperature of the charging contacts and the corresponding charging contacts equalize via the charging contacts connected in the coupled state, so that due to the pre-cooling at the start of the charging process, these have a temperature that is lower than the ambient temperature. This is particularly useful if the corresponding charging connector is equipped with an active cooling system, as described at the beginning with reference to the prior art.
  • the system provided according to the invention allows the temperature of the charging contacts of the charging connector and the temperature of the corresponding charging contacts of the corresponding charging connector to be kept below the limit temperature increase, namely until the active cooling system provided by the charging station is activated.

  • the Peltier element can protrude from the housing of the charging connector and cooling is brought about via convection.
  • fluid-based cooling can also be implemented on the hot side of the Peltier element. It is also conceivable that the hot side is thermally conductively connected to the body of a vehicle via heat pipes, so that the heat occurring on the hot side can be dissipated via the body.
  • the hot side is connected to an additional convection element in such a way that heat can be dissipated to the environment via the convection element by convection.
  • the convection element can be thermally coupled to the hot side of the Peltier element via a heat-conducting paste.
  • the convection element preferably protrudes from the housing of the charging connector in order to enable effective heat dissipation to the environment by means of convection.
