Definitions
- Connection unit for connection to an electric vehicle 1.
- the present invention relates to a connection unit for connection to an electric vehicle. Furthermore, the invention relates to an electric vehicle for connection to a connection unit. Furthermore, the invention is directed to a corre sponding ⁇ method.
- Prior Art Electric mobility is a future technology that is gaining increas ⁇ increasingly important. It is an important element ei ⁇ ner climate-friendly energy and transport policies.
- the use of electricity as a source of energy also makes it possible to use renewable energy sources for mobility, allowing for almost C02-free locomotion. Therefore, there is a need for charging infrastructures for the efficient and cost-saving charging of electric vehicles, such as electric cars or electric buses.
- the electric buses are also commonly referred to as "eBusse”.
- a known charging infrastructure consists of a control unit, a voltage source (eg Umrich ⁇ ter) and a charging point at which a vehicle can connect by means of a connection unit.
- a connection unit For example, pantographs are the connection unit of the
- the electric vehicle is charged by means of the pantograph in one charging process.
- FIG. 3 shows an exemplary charging infrastructure of the prior art with a charging station for charging a
- Electric bus by means of a pantograph As previously ⁇ leads, there is a part of the charging process of establishing a wired connection between the electric vehicle 10 and the pantograph 20. For this purpose, it is necessary, the electric vehicle 10 geometrically correctly in relation to the Pantogra ⁇ phen 20 initially position. The electric vehicle 10 is arranged ⁇ below the pantograph 20 and the pantograph 20 is then lowered in the direction of the electric vehicle 10. This process is also referred to as a positioning process and is upstream of the actual charging process.
- the electric vehicle 10 is connected to a pantograph 20 via four connections (DC +, DC-, PE, CP), as shown in FIG.
- the electric vehicle 10 can be at ⁇ play as to the above electric bus.
- the electric vehicle 10 and the pantograph 20 each have corresponding contact rails.
- the contact rails are indicated in Figure 3 in a rectangular shape and hatched. Accordingly, the charging point for the electric vehicle 10 consists of a pantograph 20 at the end of contact rails 21, 22, 23, 24 are mounted.
- the Kon ⁇ clock rails 21, 22, 23, 24 must be connected to the pantograph 20 to the contact rails 11, 12, 13, 14 of the electric vehicle 10 before the charging operation can be initiated.
- the different four connections are also called contacts and are defined as follows:
- the DC + connection establishes the connection between the positive pole of the accumulator in the electric vehicle and the positive connection of the voltage source of the charging infrastructure.
- connection DC- establishes the connection between the negative pole of the accumulator in the electric vehicle and the negative connection of the voltage source of the charging infrastructure.
- connection PE establishes the connection of the body of the electric vehicle with the earth potential of the charging infrastructure.
- the compound CP introduces be influenced by electric vehicle and Ladesta ⁇ tion and analyzable signal, thereby allowing the direct detection of a compound of this pair of rails and with appropriate mechanical construction on ⁇ indirectly detecting the connection of the further
- the contact rails 11, 12, 13, 14 of the electric vehicle 10 be arranged with the contact rails 21, 22, 23, 24 of the pantograph 20 such that they overlap in corresponding contact points 31, 32, 33, 34.
- the plan view of the roof of the electric vehicle 10 on wel ⁇ chem the contact rails 11, 12, 13, are arranged in the longitudinal direction 14 is shown in FIG. 4
- the contact rails 11, 12, 13, 14 of the electric vehicle 10 overlap in the four contact points 31, 32, 33, 34 with the contact rails 21, 22, 23, 24 of the pantograph 20, as shown.
- the electric vehicle can continue to be positioned only within a predetermined tolerance window.
- the largest possible To ⁇ leranzpper is desirable to position the electric vehicle with a high probability correct.
- the tolerance window results geometrically taking into account the number of connections to be made, conventionally four, between the electric vehicle 10 and the pantograph 20.
- FIG. 5 shows an overview of the respective tolerance windows for the four contact points.
- the arrangement of the contact bars is selected in FIG. 5 such that the contact bars 21, 22, 23, 24 of the pantograph 20 and the contact bars 11, 12, 13, 14 of the electric vehicle 10 are simultaneously arranged in pairs in the middle points 31, 32, 33 , 34 cross. Accordingly, the length of the tolerance window is:
- a disadvantage of the conventional tolerance windows known from the prior art and shown in FIG. 5 is their respective size.
- the tolerance windows are not out ⁇ sufficiently large enough for a correct and rapid positioning of the electric vehicle. Due to the limited size of the Tole ⁇ ranziza the contact rails 11, 12, 13, 14 of the electric vehicle 10 with the corresponding Needlesschie ⁇ nen 21, 22, 23, 24 of the pantograph 20 must be very precisely arranged and positioned with respect to each other.
- the pantograph 20 is first lowered during the Positionin ⁇ approximately operation on the roof of the electric vehicle 10 to produce the four points of contact points 31, 32, 33, 34 for the four compounds.
- the preparation of the compounds can be guaranteed only insufficient. If this positioning process fails and the connections can not be made as required, the panograph 20 must be restarted in a complex manner and the positioning process must be repeated. In this case, the positioning process starts again. This means that the electric vehicle 10 has to be arranged again with respect to the pantograph 20 and the pantograph 20 has to be lowered again onto the roof of the electric vehicle 10.
- the electric vehicle needs to be re-ran this yaws ⁇ and brought into another parked position below the pantograph.
- the positioning process of the prior art is very disadvantageous, namely expensive and time-consuming.
- Ran ⁇ lust at a bus stop also from the perspective of the end customer, the passenger, barely comprehensible.
- a repositioning of the bus without endangering persons is at least temporarily prevented.
- the disadvantage of this is further that the positioning process is the prerequisite for further charging. The loading process can be initiated only after successful positioning, thus if the connections between the
- the electric vehicle can not be operated properly in the sense that the passengers must remain on the one hand in the bus and on the other delayed to their destinations. This results in enormous time delays in the operation, the travel times are unnecessarily extended and the costs increase accordingly.
- the present invention therefore has the task of producing a connection of the connection unit for connection to the electric vehicle in an efficient, cost-saving and also simpler way.
- connection unit for connection to an electric vehicle comprising:
- the at least two contact rails can be connected to a corresponding first vehicle-side contact rail of the electric vehicle;
- a signal can be applied, and f. a third contact rail with a korrespondie ⁇ - generating second vehicle-side contact rail of the
- Electric vehicle can be connected. As stated above, has a connection ⁇ unit of a charging infrastructure and the electric vehicle per ⁇ stays awhile contact rails.
- the electric vehicle is to ⁇ hen ⁇ at least partially electrically powered vehicle hen ⁇ hen, which in addition to the electric drive and otherwise can be operated, crizspielswese a Verbrennungsmo ⁇ tor.
- the contact rails are matched with respect to one another in such a way that, after lowering the connection unit in the direction of the electric vehicle, the contact rails of the connection unit overlap one another with the contact rails of the electric vehicle at the contact points in order to connect the four connections (DC +, DC-, PE, CP) to produce.
- four contact points are necessary for the preparation of the four connections.
- the size of the corresponding tolerance window of the respective contact points is disadvantageously very low.
- connection unit according to claim 1 has two or more ⁇ re contact rails .
- a con ⁇ tact rail for the connection DC + and a contact rail for the connection DC- is provided.
- These contact rails are somewhat dependent on each other due to the positive and negative polarity.
- the contact rails are therefore not arranged arbitrarily, but in a certain Ab ⁇ stand from each other.
- the distance is determined so that the distance is smaller than between two mechanically independent contact rails. Accordingly, the contact rails in the immediate vicinity of each other, preferably in the longitudinal direction, arranged. However, the distance should not be too low, since this could lead to an undesirable short circuit.
- the contact rails can be connected to a corresponding vehicle-side contact rail of the electric vehicle.
- Dementspre ⁇ chend is on the side of the electric vehicle advantageously only one instead of two contact rails for the preparation of the two compounds DC +, DC- with the connection ⁇ unit necessary.
- the connecting unit a further contact rail on ⁇ on which a signal can be applied.
- the contact rail can be connected to a corresponding vehicle-side contact rail of the electric vehicle.
- the contact rail is extended by an additional monitoring functionality for monitoring the contact between the contact rails of the electric vehicle and the contact bars of the connection unit. Accordingly, on the side of the
- Electric vehicle only one instead of two contact rails for the preparation of the compounds PE, CP with the connection unit necessary.
- the number of four contact points in the prior art is reduced to two contact points by the connecting unit according to the invention and the size of the respective tolerance windows is increased.
- the connecting unit is formed as Pantog ⁇ raph.
- the connection unit may be, for example, a pantograph or a charging cable.
- an electric bus is connected to a pantograph and loaded by means of a pantograph.
- the electric vehicle is designed as an electric bus. Accordingly, the electric driving ⁇ convincing example, an electric bus, electric car, electric vehicle etc..
- the electric bus can be used for local traffic and is charged via a corresponding loading point of the charging infrastructure.
- the at least two contact rails are formed as a double contact. Accordingly, the distance between the two contact rails for the Links selected so small that even on the side of the connection unit only a double contact instead of two contact rails is required.
- the double contact can therefore also advantageously overlap with a corresponding vehicle-side contact rail in only one instead of two contact points.
- a positive voltage is applied to a first of the at least two contact rails and a negative voltage to a second of the at least two contact rails.
- the two contact bars of the connection unit are provided in particular for the connections DC + and DC-.
- the distance between the contact rails is chosen according to the polarity and its nature. Alternatively, however, the contact bars can be formed to other compounds or functionalities, for example, the United ⁇ bond CP or PE, and the distance can be adjusted accordingly.
- the third contact rail is a grounding rail on which a high-frequency and / or interference-proof signal is modulated. Accordingly, the further contact rail of the connection unit for the connections fertil PE and CP is provided. Therefore, a contact rail is saved for the implementation of two compounds. Consequently, the additional and common prior art contact rail for the connection CP is eliminated.
- the third contact rail is therefore also capable of monitoring the connection between the contact rails on the vehicle side with the contact rails on the side of the connection unit in addition to the protective function.
- the corresponding first vehicle-side contact rail of the electric vehicle ei ⁇ ne plurality of segments is divided.
- the polarity and / or a different function of each segment is not predetermined from the plurality of Seg ⁇ elements. Accordingly, it is not predetermined for which connection the respective segments of the contact rail are used.
- the respective segment can therefore be used, for example, arbitrarily for the connection DC + or DC-. Consequently, the double contact of the connection unit can advantageously also be connected as desired to the respective segment.
- the subdivision of the contact rails in + and - therefore falls away.
- on the side of the electric vehicle advantageously only one contact rail for the connection to the double contact on the side of the connection unit is necessary instead of two contact rails for the connections DC + and DC-.
- each segment of the plurality of segments at least two different ⁇ Seg ment sections, in particular a conducting and an insulating segment portion. Due to the fact that the Po ⁇ larity of the segments is not specified, the segments are divided into conducting and insulating sections. This advantageously prevents a short circuit.
- the length of the insulating segment section is greater than the respective width of the at least two contact rails. The sizing ensures that the two contact bars of the connection unit can never contact the same conductive section to avoid a short circuit. This advantageous dimensioning the contact rails can be arranged denser and thus in a space-saving manner. In addition, the production costs are significantly reduced and thus saved costs. Consequently, the size of the tolerance window can be increased.
- the lengths of the insulating and conductive segment sections could be designed so that the sum of two insulating segment sections and a conductive Segmentab ⁇ section is greater than the width of the contact rail.
- the length of the conductive segment section corresponds to the distance between the at least two contact rails.
- each segment of the plurality of segments via at least one diode with ei ⁇ nem of the at least two contact rails for applying a positive voltage or for applying a negative voltage is connected.
- the invention is further directed to a method of connecting a connection unit to an electric vehicle, comprising: a.
