- it comprises a fault current protection circuit and is used in a vehicle electrical system.
- FIG. 1 An example of such fault current monitoring in vehicles, which is used in particular in such vehicle electrical systems in which electrical voltages are present, which can be life-threatening to the human body when touched, with voltages greater than 65 volts, is shown in FIG. According to this example for the
- a residual current protection circuit is a generator 1, for example, a three-phase generator for generating voltage available.
- the output voltage of the generator or the alternator is rectified by means of an inverter 2 and via lines 3 and 4 and a switch 5 of the battery. 6 fed.
- the inverter 2 is designed for three phases bridge circuit with, for example, six PWM inverters.
- the current flowing in the lines 3, 4 current is measured in a current measuring device, wherein for current measurement, for example, a current transformer 7 is used, which determines the differential current.
- a control device 8 evaluates the measured current and disconnects the switch 5 if the measured differential current exceeds predeterminable values. The switching process is triggered by corresponding control signals that are generated by the control device 8.
- the electrical system according to FIG. 1 can also be designed as a partial on-board network of a two-voltage on-board electrical system, for example as a high-voltage side of a two-voltage on-board electrical system.
- the connection to the low voltage part is then made via a DC-DC converter, which is connected to the generator, for example.
- An example of such a two-voltage electrical system is described in DE 41 38 943 C1.
- the DC-DC converter 26, which is arranged between the two partial on-board networks, is part of a complicated charging / disconnecting module that is supplied as a function of power
- the connection between the two sub-board networks interrupts and thus prevents repercussions from one electrical system to another in the event of a fault.
- the first sub-board network includes a generator 27, a battery 28 and consumer 29, the second sub-board network, a battery 30 and consumer 31, for example, a starter. In both sub-board networks, the negative pole of the batteries 28 and 30 is grounded.
- the parenthesized reference numerals will be explained in conjunction with FIGS. 3 and 4, respectively.
- a fault current detection is difficult to implement in such a vehicle electrical system. In electrical home installations today so-called residual current circuit breakers are installed, which provide increased safety against dangerous electric shock.
- Such residual current circuit breakers which are also referred to as RCD, always trigger when a connection between the neutral and the protective conductor is made. By switching off the power behind the circuit breaker part of the circuit hazards are avoided.
- Known residual current protective devices are designed so that they require only a low tripping current for tripping and have a relatively short switch-off time.
- the vehicle electrical system according to the invention with a higher voltage with a residual current circuit having the features of claim 1 has the advantage that a residual current cutoff is realized without current measurement, which is particularly useful in a vehicle electrical system and particularly advantageous in one
- Vehicle electrical system with a subarea, which is at a higher voltage, can be used.
- a particular advantage is that only by evaluating the measured voltage drop across the two resistors, ie without further measuring device or without further sensors, an over- and / or a
- the response threshold at which the evaluation logic emits a switch-off signal or a drive signal can advantageously be adjusted to any desired fault currents, advantageously such a limit value is less than 30 mA.
- the shutdown can be done very quickly.
- an advantageous coupling of the two sub-systems is possible, which ensures that in the event of a fault on the high-voltage side, ie in the sub-board network, which is at the higher voltage, the high-voltage side is forced hard to ground.
- This advantage is achieved by connecting the two electrical systems coupled via a DC-DC converter by means of a parallel to the DC-DC converter switching element, the switching element preferably monitors the voltage between the negative high voltage terminal of the DC-DC converter and the electrical system and keeps this within certain limits.
- the switching element is a voltage-dependent resistor, a Zener diode or a switching element which is controlled by the voltage difference between the negative voltage terminal and ground.
- this circuit which is not the FI circuit, it can be ensured that the maximum permissible insulation voltage between high voltage and low voltage range is not exceeded, or with such a circuit, the system can be designed for a significantly lower isolation voltage and thus a Protection of the electrical system components or components are obtained.
- FIG. 1 shows a known and currently conventional residual current protection circuit
- FIG. 2 shows a known two-voltage on-board electrical system. Both known circuits are described in detail in the section "prior art”.
- FIG. 3 shows a block diagram for an electrical system with a residual-current-protection circuit according to the invention and FIG. 4 shows the possibility of connecting two partial-voltage systems located at different voltage levels. The explanation of the circuit shown in Figure 3 and Figure 4 is given in the following description. description
- FIG. 3 shows a vehicle electrical system or a sub-electrical system with an electric machine 10, for example a three-phase starter-generator 10 or an electric machine for a hybrid on-board network, which is connected to an inverter 11 in the usual way , From the inverter 11, which is constructed as a bridge circuit with, for example, six pulse inverters, lead two lines 12, 13 via a switch 14 to the battery 15. About these connecting lines between the battery 15 and the inverter 11 and the electric machine 10 is in normal regenerative operation the electric machine 10, the battery 15 is charged. If a starter-generator is used as the electric machine 10, the electric machine can operate as a starter in the starting case, that is to say as an electric motor and be supplied with electrical power via the inverter 11 from the battery 15.
- an electric machine 10 for example a three-phase starter-generator 10 or an electric machine for a hybrid on-board network
- a parallel connection of a resistor 16, a capacitor 17 and a voltmeter 18 is provided in the embodiment of Figure 3.
- a resistor 19 Between the line 13 and ground are a resistor 19, a capacitor 20 and a
- Voltmeter 21 connected in parallel.
- the two capacitors 17 and 20 are not essential.
- Both the voltmeter 18, which measures the voltage drop across the resistor 16 and the voltmeter 21, which determines the voltage drop across the resistor 19, are connected to the evaluation logic 24 and provide the latter with the measured variables which are to be evaluated.
- the associated connections between the voltmeters 18 and 21 are indicated at 22 and 23, respectively.
- the evaluation logic 24 detects a fault current by evaluating the voltages, it sends control signals to the switch 14 via a connection 25 and actuates the latter and disconnects the battery. This will be the electrical system de-energized.
- both connecting lines 12, 13 between the battery 15 and the inverter 11 and the connected to the inverter 11 generator 10 is interrupted and ensures residual current protection.
- the exemplary embodiment according to the invention according to FIG. 3 is characterized in that a fault current cut-off is possible which requires no current measurement. It is essential that high-voltage lines in the electrical system can be on which are much higher voltages than 12 volts. In a vehicle electrical system for a hybrid vehicle, the voltage on the high-voltage side is, for example, 65 volts and more, but under certain conditions significantly higher voltages of up to 288 volts may be present. Under these conditions protection by means of FI wiring is absolutely necessary. In a 12/42 vehicle electrical system such protection may also be appropriate.
- both connecting lines 12, 13 are connected via at least one high-resistance resistor 16 and 19 to ground.
- Voltmeter 18 and 21 measured voltages changes and thus the fault current is detected.
- the two measured voltages for example, the evaluation logic 24 are supplied and the fault current detection in the evaluation logic 24 are performed.
- One way of error detection is, for example, by comparing the determined
- the vehicle electrical system shown in FIG. 3 can also be a high-voltage network of a vehicle located at an elevated voltage of, for example, 288 volts relative to the usual vehicle electrical system voltage of 12 volts, which is connected to the usual vehicle electrical system, for example via a voltage converter.
- the high-voltage network has in the embodiment shown in Figure 3 no low-impedance connection to the vehicle ground.
- the high-resistance resistors 16 and 19 and the capacitors 17, 20 are provided. If these are the same in pairs, the net is kept symmetrical to the vehicle mass. It is essential that the values of the resistors are so high that no significant loss caused by the resistors, so there is no relevant current from the
- the evaluation logic 24 which detects the fault current from the comparison of the two voltages can be set to almost any fault current, usually to a fault current of less than 30 milliamps (mA). When the set fault current is reached, the evaluation logic 24 outputs a corresponding signal to the switch 15 and opens it.
- the high-voltage system In a vehicle with a two-voltage electrical system should, if no other protective measures are taken, for safety reasons, the high-voltage system must be potential-free to earth, for example to the housing and additionally designed touch-safe. This means that a potential separation between the high voltage and the low voltage electrical system must be ensured. this applies especially since in the low voltage electrical system with a nominal voltage of usually 12 volts, the vehicle body is the negative pole.
- the high voltage electrical system which is for example up to 288 volts and possibly more, very high impedance connected to the body potential, so that the voltage potentials can not drift arbitrarily.
- This voltage connection is obtained by the symmetry resistors 16, 19 and / or the capacitors 17, 20. Assuming these facts, it can be seen from the two measured voltages or voltage drops across the resistors 17, 19 by comparing the voltages with each other whether the overall system is in order.
- the ratio of the resistance values of the resistors 16 and 19 will be the same as the ratio of the two measured voltages.
- the resistor voltage divider warps accordingly as through the two resistors 16, 19 different currents flow.
- the then adjusting change in the ratio of the two voltage drops can be detected in the evaluation logic 8 and a response to be triggered.
- This reaction may consist, for example, in the shutdown of the high voltage. Such a reaction is triggered, for example, when the displacement of the voltage divider reaches predeterminable values. These values can again be selected relatively freely.
- FIG. 4 illustrates an embodiment of the two-voltage on-board electrical system according to FIG. 2, in which the coupling of the two subnetworks is implemented via the DC-DC converter 32.
- the first part of the electrical system includes a generator 33 including the inverter, not shown separately, a battery 34 and consumer 35, the second electrical system a battery 36 and consumer 37th Das
- Low voltage electrical system (12 / 14V) is grounded with the negative pole of batteries 36 grounded.
- the high voltage electrical system is, however, connected as a controlled floating traction network, for coupling to the low voltage electrical system in addition to the DC converter 32 is still a switching element 38 is parallel to the DC-DC converter and this switching element is a voltage-dependent switching element, the voltage between the negative High-voltage connection (B-) and the wiring material monitored and keeps within certain limits.
- the function of the parallel to the DC-DC converter 32 switching element 38 in its embodiments is the following: Once the reference potential of
- an active switching element instead of a Zener diode or a voltage-dependent resistor.
- One possible embodiment shows 38c.
- Such a switching element 39 must at least consist of a unit for measuring voltage and a switch.
- a network of coil, capacitor and resistor can be provided and placed in front of the switch. In the event of a fault, the switch can be closed and the high voltage side can be grounded.
