- This provides additional short-circuit protection.
- the plurality of circuit breakers ie by means of at least two circuit breakers
- the charging current in dependence on the determined current-carrying capacity is passed (ie, for example in dependence on the detected Wi ⁇ derstandswert) automatically via one of the at least two circuit breakers, while the other circuit breaker or the charging current remain free.

It is particularly before ⁇ part way that for different charging cable having a current carrying capacity between 50% and
- the procedure can also be such that
- the charging current is conducted through a circuit breaker with rated current 32 A and tripping characteristic C, or
- a charging device for charging a traction battery of an electrically drivable vehicle, which is designed to carry out the methods or method variants described above. This charging device also has the advantages that are mentioned above in connection with the inventive method.

- Figure 2 shows another embodiment of a
- FIG. 1 illustrates a charging device 1 for charging a battery 3 driving an electrically driven vehicle 5 is Darge ⁇ represents.
- This charging device 1 is connected by means of a connection ⁇ cable 8 with a power grid 10.
- Electric power is supplied from the power grid 10 via the connection cable 8, a residual current circuit breaker 12 and a circuit breaker 14 to a switching device 16 of the charging device 1.
- the switching device 16 may e.g. be designed as a switch or a contactor, in particular as a power contactor.
- the electric current is passed as a charging current via a current measuring device 20 to a charging interface 22 of the charging device 1.
- This charging interface 22 is designed in the embodiment as a La ⁇ decoder socket (charging socket) 22.
- the current measuring device 20 can be designed, for example, as a current transformer or as a smartmeter with a current measuring function.
- a charging connector 24 of a La ⁇ delies 26 can be inserted in the charging interface 22 in the charging interface 22 in the charging interface 22 .
- the charging cable 26 connects the charging device 1 by means of a second charging plug 28
- the charging connector 24 is configured in the embodiment as a so- ⁇ -called type-2 connector constructed in accordance with the standard IEC 62196-2. This connector has seven electrical contacts: four contacts for the transmission of three-phase alternating current, a contact "Pilot”, a contact "Proximity” and a contact "PE” (standard IEC 61851-1) Between the contacts "Proximity” and "PE “a resistor 48 is inside the connector 24 built in.
- the ⁇ ses resistance device 48 By means of the ⁇ ses resistance device 48 is coded, the current carrying capacity and the rated current of the charging cable 26 in accordance with standard IEC 61851-1. (a similar resistor is in the loading ⁇ plug 28 built-in.)
- the resistor 48 is also referred to as a "proximity resistor”. He gives the maximum
- the charging cable 26 comprises only 6 wires / wires, since this has no line for the contact "proximity.”
- the control device 30 is designed in the embodiment as a microcontroller. This control device 30 is connected to a memory 32 and can read data from this memory and write in this memory.
- data for overload protection of charging cables with different current carrying capacity are saved ⁇ chert. For example, data for overload protection of a 32 A charging cable and data for overload protection of a 20 A charging cable are stored in the memory.
- the Spei ⁇ cher data storage
- data storage for example, as a Flashspei- rather be designed ROM, EPROM or EEPROM.
- these data include a plurality of current values and respective power-down times associated with these current values.
- This data may represent, for example an overload characteristic or reproduce, similar to an overload characteristic of a circuit breaker with Auslettecha ⁇ rakterizing C, so that the overload function of the circuit breaker can be simulated by means of the control device.
- the following data is stored in the memory 32 for the 20 A charging cable:
- control device is electrically connected to a Zeitmessem- direction 34.
- the control device 30 is connected via signal lines to the interface 22, to the current measuring device 20 and to the switching device 16. Among other things, the control device 30 controls the switching device 16. In addition, the control device 30 is connected by means of signal lines to a remote drive 36 of the circuit breaker 14 and / or to a remote drive 38 of the residual current circuit breaker 12. Instead of the remote drive 36, a shunt release for the circuit breaker 14 Fault current protection switch can be used.
- a remote actuator also called a reset actuator
- a working current release is a device which is mechanically coupled to a line ⁇ breaker and which is able to turn off the circuit breaker.
- the charging device 1 determines the current carrying capacity of the charging cable 26. This is done by the controller 30 determines the resistance of the resistor 48 of the charging connector 24. The resistance value of the counter ⁇ stands 48 is measured and transmitted to the controller 30 by means of a message 50th In the exemplary embodiment, this resistance value is 680 ohms. This recognizes the
- Control device 30 that the current carrying capacity of the Ladeka ⁇ lever 26 has the value 20 A.
- the controller 30 reads out from the memory 32 the data for the overload protection of a 20 A charging cable
- the current measuring device 20 the current strength of the charging current flowing through the charging cable 26 (and thus also through the current measuring device 20) is measured and a corresponding current value is formed.
- This current value is transmitted to the control device 30 by means of a message 54.
- the control device 30 now compares this current value of the measured current with the value of the current carrying capacity of the charging cable. If the current value indicates currents less than or equal to 20 A, then there is no overload and no action is necessary. In the exemplary embodiment, however, it is assumed that the current value has a current intensity of 30 A.
- a current of 30 A is 1, 5 times the
- the control device 30 then starts a time measurement by means of the time measuring device 34. After reaching the switch-off time (ie after 4 minutes) sends the controller 30 a message 56 and a signal 56 to the switching device 16 and has by means of this message 56, the switching input ⁇ device 16 to interrupt the current flow.
- the switching input ⁇ device 16 In the embodiment, is open to the overall message 56 toward the contactor 16 so that the current flowing through the charging cable 26 charging ⁇ current is interrupted. This protects the charging cable against overload.
- Auxiliary contacts which move together with the main contacts. Therefore, based on the mirror contacts can always be recognized as the main contacts are (ie whether they are CLOSED ⁇ sen or open). For example, it can be detected if the main contacts do not open.
- two further switching devices are provided. available. With one of these two other switching devices then the charging current can be switched off.
- a second switching device is the line protection switch 14, which is provided with a remote drive 36.
- a remote operator 36 is an auxiliary device by means of which the circuit breaker can be switched on and off. Therefore, in the event of failure of the switching device 16, the control device 30 sends a message 60 to the remote drive 36 and instructs the latter to switch off the circuit breaker 14. Thus, the charging current is switched off by the charging cable 26.
- the controller 30 may also send a message 62 to the remote operator 38 of the residual current circuit breaker 12. With this message 62, the remote drive is ⁇ sen, the fault current circuit breaker 12 off. Even so the current flowing through the charging cable charging current can be Tar ⁇ on. It is sufficient if a further switchable by the control device switching device is present in a charging device. It is therefore sufficient if either the remote operator 36 or the remote operator 38 is present.
- the control device 30 uses the resistance value of the resistor 48 to determine that a 32 A charging cable is present. Then loads the Steuerein ⁇ device 30 from the memory 32 from the data for an overload protection of a 32 amp charging cable.
- the further method steps correspond analogously to the method steps described above in connection with the 20 A charging cable.
- the overload protection can also be performed by the 32 A circuit breaker 14. Both when using a 32 A charging cable as well as when Ver ⁇ use of a 20 A charging cable short-circuit protection for the charging cable is realized by the circuit breaker 14. In both mentioned charging cables comes as line protection switch 14, a circuit breaker with the rated current 32 A and the tripping characteristic C is used.
- the short-circuit protection of the 20 A charging cable is realized with a 32 A circuit breaker. This is possible because in charging devices both line breaker the tripping characteristic C and circuit breaker the tripping characteristic D are allowed. According to the standard IEC / EN60898-1 or DIN VDE 0641-11, the tripping characteristic C and the tripping characteristic D differ with regard to the currents at which the short-circuit tripping starts.
- the circuit breaker with tripping characteristic D in short circuit only at higher relative currents (ie at larger multiples of the rated current or rated current) turn off than the circuit breaker with tripping characteristic C. Therefore acts a circuit breaker with rated current 32 A and tripping characteristic C similar Similarly, a miniature circuit breaker with rated current 63 A and tripping characteristic C acts similarly as a circuit breaker with rated current 32 A and tripping characteristic D. Another example acts a line ⁇ breaker with rated current 20 A and Tripping characteristic C similar to a miniature circuit breaker with rated current 13 A and tripping characteristic D. This is to be clarified on the basis of a calculation example.
- the circuit breaker with rated current 32 A and tripping characteristic C can also be used as a circuit breaker for a rated current 20 A and tripping characteristic D.
- FIG. 2 shows a charging device and a method which, unlike FIG. 1, are suitable for charging cables with current carrying capacities of 13 A, 20 A, 32 A and 63 A. It is the first circuit breaker 14 'a
- Circuit breaker with a rated current of 20 A and a tripping characteristic C is used. Parallel to this first circuit breaker 14 ', a second circuit breaker 70 is connected, which can be switched with another switching device 72 in the charging circuit.
- the circuit breaker 70 is provided with a remote drive 73.
- the switching means 16 ' is provided as a 20 A switching device, so for example, as a 20 A contactor freshlystal ⁇ tet, the switching device 72 is as a 72A-switch device, so configured, for example as a 72A contactor.
- the switching devices 16 'and 72 are switched so that only either the switching device 72 or the
- Switching device 16 ' may be closed. In other words, the switching device 16 'and the further switching device 72 are "cross-locked.” Thus, the charging current flows either through the circuit breaker 14' or through the circuit breaker 70.
- the memory 32 also data for the overload protection of a 13 A charging cable and a 63 A charging cable are stored. The method runs in the embodiment of Figure 2 fol ⁇ gender inspirationalen. After connecting the charging cable 26 to the interface 22, the resistance of the resistor 48 is determined and thus determines the current carrying capacity of the charging cable 26. If the charging cable 26 has a current carrying capacity of 63 A or 32 A, then the controller 30 sends a message 74 to the switching device 16 'and instructs it to remain in the open state.
- control device 30 sends a message 76 to the further switching device 72 and instructs them to close their contacts and to allow the flow of current through the circuit breaker 70.
- the entire La ⁇ flow from the residual current circuit breaker 12 via the circuit breaker 70, the other switching device 72, the current measuring device 20 and the interface 22 to 26 Ladeka- 26 flows.
- the controller 30 detects that the charging cable 26 has a current carrying capacity of 20 A or 13 A, then the controller 30 sends a message 74 'to the switching devices 16' and instructs this switching device 16 'to close. Furthermore, the control device 30 sends a message 76 'to the switching devices 72 and instructs this switching device 72 to open. In this case, the entire charging current flows from the residual current circuit breaker 12 via the circuit breaker 14 ', the switching device 16', the current measuring device 20, the interface 22 to the charging cable 26.
- the other procedures correspond mutatis mutandis to the procedures described in connection with Figure 1.
- a charging device for charging a traction battery of an electrically driven vehicle and a method for protecting a charging cable has been described.
- This charging device and this method make it possible to realize in a simple and cost-effective manner both an overload protection and a short-circuit protection for the charging cable.
- the overload protection and the short-circuit protection can be realized easily and at low cost for charging cables of various current carrying capacities.
- the short circuit protection can advantageously be realized with a small number of circuit breakers.
- the protection of the charging cable is divided into two parts systems or parts procedures.
- the overload protection of the charging cable is realized by means of a control device (for example, a microcontroller) and associated memory, the short-circuit protection of the charging cable, however, with circuit breakers.
- the overload protection serves to protect the charging cable from overload and thus from inadmissible heating. If, for example, a 13 A charging cable runs through in the event of a fault of 63 A, then the 25-fold power loss occurs and is distributed in the cable. Then you can expect health-endangering temperatures on the cable surface and damage to the cable is to be feared. In order to avoid this, the excessive current intensity is detected during overload protection and the current is switched off by means of a switching device, in particular a power contactor .
