Description

  • TECHNICAL PART
  • This description refers to de-energizing a vehicle for a rescue operation.
  • BACKGROUND
  • In the event of an accident, fire, or other emergency of a vehicle, particularly an electric vehicle (EV), firefighters or other rescue workers can be at risk of electric shock or electric arc due to the unknown status of the vehicle's electrical power supply. Various solutions for warning or protecting people from electric shocks from electrical energy sources of vehicles are known from the following prior art documents:
    • The German patent application DE 100 58 898 A1 discloses a system with a battery, a starter, a generator and a pre-crash sensor arrangement. The starter and the generator are connected to one another and a disconnect switch is arranged between the battery and the starter, which reversibly disconnects the connection between the battery and the starter when the pre-crash sensor arrangement detects an accident.
  • The European patent application EP 0 825 068 A1 discloses an emergency stop switch for a vehicle electrical system, which has a sensor working with a switch, in particular a crash and impact sensor. In the event of a collision with a vehicle, the electrical energy supply path is interrupted immediately.
  • The U.S. patent US 6,417,579B1 relates to a starter circuit for a motor vehicle that includes a circuit breaker that responds to a crash sensor to disconnect the starter circuit. A bypass switch is provided which responds to a control circuit in order to supply the starter circuit with current after the switch has been activated when the starter circuit is free of short circuits.
  • The international patent application WO2015117755A1 relates to an electrical high-voltage motor vehicle system which has a high-voltage battery and a consumer network, which are connected to one another by an electrical cable, and a quick-action switch for disconnecting the high-voltage battery from the consumer network. The quick switch receives an airbag signal.
  • The U.S. patent US9,221,343B2 discloses a system for decoupling a high voltage source from the electrical system of an electric vehicle that includes at least one electrical contactor, the high voltage source being electrically connected to the electrical system of the vehicle when the electrical contactor is in a closed state and not electrically to the electrical System of the vehicle is connected when the electrical contactor is in an open state; an additional restraint system that monitors collision data from a variety of crash sensors and outputs an activation signal in response to monitored collision data; and a pyrotechnic switch, the pyrotechnic switch having a pre-activated first state that provides a conductive path that enables electrical connection of the high voltage source to the electrical system of the vehicle and an activated second state that interrupts the conductive path and prevents that the high voltage source is electrically connected to the electrical system of the vehicle.
  • The German patent application DE 42 08 011 A1 discloses an apparatus operatively coupled to an occupant restraint actuator that is triggered by an accelerator limit switch. The connection of the electrical consumers inside the vehicle to the positive pole of its battery is interrupted by a contact that simultaneously activates an electronic timer. An incandescent lamp is caused to send lightning bolts in optical cables to the four direction indicators so that they emit the conventional hazard warnings. The possibility of indicating a hazard by flashing the indicator lights is not affected if all other consumers are disconnected from the positive pole of the battery.
  • The European patent EP 0 791 942 B1 relates to an electrical system with a battery line for coupling an electrical generator to a storage battery that is used to supply several electrical consumers via a consumer line, a switch being actuated in an accident to disconnect the battery. The switch is actuated to open both the battery line and the consumer line.
  • The U.S. patent US5,818,122B relates to a circuit breaker control unit that receives an impact detection signal that is output from the outside when an impact such as a crash of a motor vehicle has been detected and generates and applies a circuit breaker control signal based on the impact detection signal. A circuit breaker unit forcibly interrupts a power supply path and stops power supply to a consumer. Therefore, the power supply can be stopped immediately when the impact is detected. In addition, a second consumer is a minimal electrical system that is essential to get the motor vehicle to drive. Therefore, even if the power supply to the consumer is cut off, the motor vehicle can be made to drive. Thus, the motor vehicle can be easily moved to the edge of a road or the like in an accident or the like.
  • The international patent application WO2013087328A2 relates to a motor vehicle, which comprises a motor vehicle body, an electrical energy store and an electric motor, which is connected via an electrical cable and is used to drive the vehicle or to assist in driving the vehicle. In addition, a switching means can be activated by an emergency signal to interrupt the electrical cable. The motor vehicle is characterized in that at least one signal line is integrated in the vehicle body. If the signal line is interrupted, the emergency signal is generated to activate the switching means.
  • SUMMARY OF THE INVENTION
  • This description refers to de-energizing a vehicle for a rescue operation.
  • According to one aspect of this description, a system for de-energizing a vehicle for a rescue activity is provided, which has an electrical energy source of the vehicle, at least one power cable for supplying one or more electrical consumers (s) with electrical energy from the electrical energy source of the vehicle, at least one controllable switch, which is connected between the electrical energy source and the one or more electrical consumers in the at least one power cable, and has at least one control cable that has a length to be arranged in the vehicle so that it is from the outside Vehicle is severable, wherein the at least one control cable is further provided to connect a control input of the at least one controllable switch to a switch control that sends a control signal via the at least one control cable to the control input of the at least one controllable switch age transmits, so that the at least one controllable switch is switched to a closed state in order to supply the one or more electrical consumers with electrical energy from the electrical energy source, and wherein one or more of the at least one control cable is an optical cable and the Switch control is configured to generate an optical control signal that is to be transmitted via the at least one control cable to an optical control input of the at least one controllable switch.
  • According to a further aspect of this description, a vehicle is provided which has an electrical energy source, at least one power cable for supplying one or more electrical consumers (s) with electrical energy from the electrical energy source, at least one controllable switch which is connected between the electrical energy source and the one or more electrical consumers is connected into the at least one power cable and has at least one control cable which has a length and is arranged in the vehicle such that it can be severed from outside the vehicle, the at least one control cable also being provided, to connect a control input of the at least one controllable switch to a switch control which transmits a control signal via the at least one control cable to the control input of the at least one controllable switch, so that the at least one controllable switch is closed enen is switched to supply the one or more electrical consumers with electrical energy from the electrical energy source, and wherein one or more of the at least one control cable is an optical cable and the switch controller is configured to generate an optical control signal, the is to be transmitted via the at least one control cable to an optical control input of the at least one controllable switch.
  • The use of an optical cable has the advantage that it can be more easily damaged in an accident or crash of the vehicle than an electrical cable, so that the vehicle can be de-energized with a higher probability. In particular, sensitive optical cables can be used, which can be damaged by a high impact force, which typically occurs in particularly severe vehicle accidents, so that they can no longer transmit a control signal or an impaired control signal. The control cables can only have optical cables or a mixture of optical cables and electrical cables. For example, optical cables can be used in vehicle structures that are more likely to be damaged even in minor accidents with less impact, while electrical cables can be used in more crash-resistant structures that are typically damaged, in particular deformed or broken, in severe vehicle accidents with high impact forces be, so the probability of the vehicle at De-energizing accidents can be increased in any type of accident.
  • The at least one control cable can be provided in order to be arranged in the vehicle on and / or within one or more / more vehicle support structure (s) in such a way that the at least one control cable is severed if the one or more support structure (s) is outside of the Vehicle are severed. For example, the one or more support structures can comprise one or more pillars of the vehicle.
  • One or more of the at least one control cable may be an electrical cable, and the switch controller is configured to generate an electrical control signal that is to be transmitted via the at least one control cable to an electrical control input of the at least one controllable switch.
  • The details of one or more embodiments are included in the accompanying drawings and the description below. Further features and advantages result from the description and the drawings as well as from the claims.
  • Figure list
    • 1 shows a schematic representation of an electric vehicle with an embodiment of the device for de-energizing.
  • DETAILED DESCRIPTION
  • In the following, functionally similar or identical elements can have the same reference symbols. Absolute values are only shown as examples below and should not be understood as a limitation.
  • 1 shows a schematic representation of an electric vehicle (EV) 10th with a battery pack integrated in the underbody of the EV 12th to supply the electrical consumers of the EV 10th , in particular an electric motor 16 , and other consumers like backlighting 18th , Front lights, control units, safety devices such as airbag systems, automatic brake control systems, electronic driving stability systems, driver assistance systems such as automatic vehicle speed control systems, distance control systems, lane keeping systems, an energy management system, a powertrain control system, a user interface system etc. The battery pack 12th may comprise a plurality of lithium-ion batteries which are connected in such a way that an electrical voltage of typically several hundred volts, for example in the range from 300 to 400 volts, is generated at the output of the battery pack, which is sufficient to cover all electrical consumers, in particular the engine 16 , to supply.
  • The through the battery pack 12th generated voltage can in an accident of the EV 10th be dangerous for people, especially for firefighters and rescue personnel. When opening the EV 10th After an accident, especially with cutting tools, the personnel can be endangered in particular by potentially dangerous electric shocks and arcs, for example if a power cable 14 to supply electrical consumers 16 , 18th with electrical energy from the battery pack 12th is damaged by a cutting tool.
  • In order to avoid such a danger to the rescue personnel, there is a controllable switch 20th to interrupt the power cable 14 provided and in the power cord 14 between the battery pack 12th and the electrical consumers 16 , 18th switched. The controllable switch 20th is particularly close to the output connector (s) of the battery pack 12th positioned to the power cord 14 and the electrical consumers 16 , 18th disconnect safely from the voltage generated by the battery pack. The controllable switch 20th can, for example, directly at the outlet (s) of the battery pack 12th or near the exit (s) also in the underbody of the EV 10th be positioned.
  • The control input of the controllable switch 20th is via a control cable 22 with a switch control 24th connected. The switch control 24th is provided to a control signal via the control cable 22 to the control input of the controllable switch 20th to generate and transmit so that the switch 20th is in a closed state and the electrical consumer 16 , 18th through the battery pack 12th be supplied. The switch control 12th can, for example, by a separate power supply to the EV 10th are fed, for example, by a 12 V vehicle electrical system with a standard car battery, which has a low voltage output to supply low power consumers of the EV 10th generated. When starting the EV 10th by a driver the switch control 12th are supplied with this separate power supply, then the control signal is generated and sent to the controllable switch 20th transferred so the switch 20th closed and operated in a closed state. Thus, the electrical consumers 16 , 18th via the closed switch 20th with the outputs of the battery pack 12th connected and via the power cable 14 powered.
  • The control cable 22 can have a length to be in the EV 10th to be laid and installed to along and / or through structures and / or parts of the EV 10th to run away from outside the EV 10th can be severed. For example, the cable 22 in or on the pillars of the EV 10th to be relocated: In 1 the cable goes 22 through the B-pillar 28 and the A pillar 26 . The two pillars 26 and 28 can, for example, along the cutting lines 30th and 32 be severed if, in an emergency, people within the EV 10th should be saved.
  • The control cable 22 can also in the EV 10th are arranged and laid to run along and / or through structures and / or parts of the EV 10th to run, which can in particular be lightweight structures that are damaged first in the event of an accident, in particular also when only small impact forces are exerted on these parts and / or structures in the event of an accident.
  • The length and arrangement of the control cable 22 can ensure that when cutting one or more of the columns 26 , 28 of the EV 10th by the rescue personnel with cutting tools also the cable 22 is severed. Cutting the control cable 22 interrupts the transmission of the control signal from the switch control 24th on the controllable switch 20th , which changes its state from closed to open, thereby powering the electrical consumers 16 and 18th interrupted and the components of the EV 10th be de-energized, which are normally supplied with electrical energy from the battery pack. This significantly reduces the risk and danger for the rescue personnel to suffer from dangerous events such as electric shocks or arcing.
  • The control cable 22 comprises at least one optical cable and can also comprise one or more further cables, for example a further optical and / or electrical cable. The at least one optical cable can be selected such that it can easily be damaged by an accident so that it can no longer transmit the control signal, or it transmits an impaired control signal from the switch control 24th to the switch 20th , so it may not be necessary to cut this cable.
  • The switch control 24th is implemented to generate the control signal as an optical signal and via the optical control cable 22 to an optical input of the controllable switch 20th transferred to. In particular, the switch control 24th comprise at least one light emitting diode (LED) and one or more optical connections for one or more optical cables. The desk 20th can in particular also have one or more optical connections for one or more optical cables and furthermore one or more photodiodes for converting optical signals received via one or more optical cables connected to one or more connections into electrical signals for further purposes Processing as described below.
  • The desk 20th can be configured to one over the at least one optical cable 22 Process received optical control signal in order to determine the desired switch position, in particular in the closed state for operating the electrical consumers 16 , 18th through the battery pack 12th to switch when there is an optical signal over the at least one optical cable 22 is received, wherein one or more signal parameters of the received optical signal correspond to one or more expected parameters, for example the received optical signal has an expected signal level or an expected signal strength, an expected frequency spectrum, an expected signal modulation and / or transmitted information. In addition, the switch 20th configured to switch to the open state to power the battery pack 12th to consumers 16 , 18th to interrupt if it determines that no optical signal is received at all, for example if the at least one optical cable 22 interrupted, or if it determines that the received optical signal is an impaired signal, since its signal parameters do not match one or more expected parameters, for example the signal level or the signal strength is below a predetermined threshold, the frequency spectrum is not within an expected frequency range , the signal modulation does not match the expected modulation and / or information transmitted with the optical signal cannot be extracted, since the received signal is a disturbed optical signal due to damage to the at least one optical cable 22 acts, for example, by an accident of the EV 10th was caused.
  • If an electrical cable is used as a control cable in addition to the at least one optical cable, this is from the switch control 24th generated and over the control cable 22 Control signal typically transmitted a low voltage signal, which the rescue personnel when cutting the cable 22 with cutting tools would not endanger.
  • The control signal can be a stationary signal with predetermined levels (eg between different signal levels, in particular two light intensities for the “on” state of an optical signal and 10 and 14 V for the “on” state an electrical signal), or an alternating signal with a certain amplitude and / or frequency, or a pulsed signal with pulses at fixed or variable intervals. The "on" state can be defined by the presence of a predefined level, a fixed frequency or by pulses at predefined intervals. The “off” state can be defined by the lack of such a predefined level, a predefined frequency signal or a pulsed signal. The control signal may also be provided for transmitting information, such as a predetermined sequence of codes that determine the "on" state, the information being able to be transmitted as a digital signal without error correction coding, so that in the event of a transmission error due to damage of the control cable the receiving switch 20th damage to the control cable 22 can recognize.
  • The controllable switch 20th can, as described above, be designed as a normal-off switch which is switched on or brought into a closed state by a corresponding control signal which is received by the switch control via its control input. Generally the controllable switch 20th a switching device that operates in a closed state when a particular signal is received at the control input of the switch and in an open state when the particular signal is not received at its control input. For example, a contactor, a circuit breaker or even a fuse that can be triggered externally (pyro switch) can be used to implement the controllable switch 20th be used. An interruption in the control line 22 that send the control signal to the control input of the controllable switch 20th transmits, the OFF function of the controllable switch must trigger irreversibly, so that the circuit behind the switch 20th , ie on the consumer side, is dead.
