Abstract

In order to ensure the provision of starting energy in motor vehicles with internal combustion engines, the voltage of the starting battery is monitored whenever the generator of the vehicle's electrical system has been stationary. When the voltage drops below an adjustable voltage limit, the starting battery is disconnected from the vehicle's electrical system via a voltage-controlled relay switch K2.

In Kraftfahrzeugen, insbesondere in Personenkraftwagen hat die Startbatterie üblicherweise auch die Speisung des Bordnetzes zu übernehmen. Außerdem sind häufig Zusatzverbraucher über Außenbordsteckverbindungen zu versorgen. Bei Stillstand des Bordgenerators führt der weitere Betrieb von Verbrauchern zur Entladung bzw. Tiefentladung der Startbatterie, wenn keine Schutzmaßnahmen zur begrenzten Stromentnahme getroffen sind.In motor vehicles, especially in passenger cars, the starter battery has usually also take over the supply of the electrical system. In addition, there are often additional consumers via outboard connectors to supply. Operation continues when the on-board generator is at a standstill by consumers to discharge or deep discharge the starter battery, if no protective measures for limited power consumption are taken are.

Die Sicherstellung von ausreichender Startenergie ist gegenüber der Versorgung des Bordnetzes vorrangig und für die Fahrpraxis von grundlegender Bedeutung.Ensuring sufficient starting energy is compared to the supply of the on-board electrical system primarily and of fundamental importance for driving practice Importance.

Diese Verfahren, durchweg als Kontroll- oder Warneinrichtungen bezeichnet dienen dem Ziel, Tiefentladungen der Startbatterie durch Bordnetzverbraucher zu verhindern. Sie bieten jedoch keinen echten Schutz, da ihre Wirkung effektiv von der Aufmerksamkeit des Fahrzeugführers abhängt.These procedures, consistently referred to as control or warning devices serve the goal of deep discharges of the starter battery by electrical system consumers to prevent. However, they do not offer one real protection, as its effect effectively from the driver's attention depends.

Gruppe 2: Verfahren und Schutzschaltungen für KFZ-Batterien gegen Tiefentladung, die den Betrieb von Zusatzbatterien- oder Zusatzverbrauchern betreffen: DE-PS 32 35 349 C2, DE-OS 36 22 157 A1. Group 2: Processes and protective circuits for automotive batteries against deep discharge, the operation of additional batteries or additional consumers concern: DE-PS 32 35 349 C2, DE-OS 36 22 157 A1.  

Diese Schaltungen bewirken eine Abschaltung der Zusatzverbraucher bei einer vorgegebenen Akkumulator-Spannungsuntergrenze. Die Stromkreise des Bordnetzes sind jedoch in den Schutz nicht mit einbezogen.These circuits cause the additional consumers to be switched off a predetermined accumulator voltage lower limit. The circuits of the electrical system are not included in the protection.

Diese Verfahren und Schutzschaltungen sind an ihren jeweiligen Verwendungszweck gebunden. Eine direkte Verwertbarkeit zur Sicherstellung der Startenergie in Kraftfahrzeugen ist nicht gegeben.These methods and protective circuits are specific to their intended use bound. A direct usability to ensure the There is no starting energy in motor vehicles.

Weitere Nachteile der bekannten Schutzschaltungen:Further disadvantages of the known protective circuits:

Bei vollelektronischen Lösungen tritt im Leistungsteil unerwünschte Verlustwärme auf.With fully electronic solutions, undesired heat loss occurs in the power section on.

Eine Spannungsstabilisierung des Elektronikteils der Schaltungen ist nicht vorgesehen bzw. nicht erkennbar. Hierdurch ist ein exaktes Schaltverhalten nicht möglich. Schwingneigung im Schaltpunktebereich, sowie starke Temperaturabhängigkeit sind die Folge.A voltage stabilization of the electronic part of the circuits is not provided or not recognizable. This is an exact switching behavior not possible. Vibration tendency in the switching point area, as well The result is a strong dependence on temperature.

Die vom Bordgenerator und seiner Regeleinheit erzeugten Spannungsspitzen können elektronische Bauteile zerstören, wenn keine wirksame Entkopplung vorgesehen ist.The voltage peaks generated by the on-board generator and its control unit can destroy electronic components if there is no effective decoupling is provided.

Bei allen Schaltungen fließen auch im Sperrzustand noch unterschiedlich hohe Ruhe- bzw. Restströme. Die in DE-OS 27 32 794 wiedergegebene Schaltung benötigt zur Erhaltung des Aus-, bzw. Sperrzustandes Hilfsenergie, die im Interesse hoher Betriebssicherheit zu vermeiden ist.All circuits still flow differently even in the blocked state high quiescent or residual currents. The circuit shown in DE-OS 27 32 794 needs auxiliary energy to maintain the off or locked state Avoid interest in high operational safety.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine neue Schaltungsanordnung zur Sicherstellung der Startenergie in Kraftfahrzeugen mit Verbrennungsmotoren zu schaffen, die bei abgeschalteten Verbrauchern keinen Strom aufnimmt, zur Erhaltung dieses Schaltzustandes keine Hilfsenergie benötigt. Außerdem soll ein umfassender Schutz durch Erfassung aller entladungsfähiger Stromkreise des KFZ-internen Bordnetzes und solcher, die über Außenbordnetzsteckvorrichtungen betrieben werden können gegeben sein. The invention is therefore based on the object of a new circuit arrangement to ensure the starting energy in motor vehicles with To create internal combustion engines that none when consumers are switched off Consumes electricity, no auxiliary energy is required to maintain this switching state. In addition, a comprehensive Protection through detection of all discharge capable circuits of the Vehicle internal electrical system and those that have external electrical system plug devices can be operated.  

Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.This problem is solved with the characterizing features of the claim 1. Advantageous refinements can be found in the subclaims.

Als Lastschalter ist ein bistabiles Drehanker-Stromkreisrelais vorgesehen, das neben minimaler Anspruchleistung den Vorteil des Speicherverhaltens aufweist, d. h. kein Energiebedarf in beiden Schaltzuständen.A bistable rotary armature circuit relay is provided as the load switch, which has the advantage of storage behavior in addition to minimal demand, d. H. no energy consumption in both switching states.

Vorteilhaft ist weiter die hohe Störsicherheit durch Entkopplung der Steuerelektronik vom Bordgenerator durch ein Hilfs-Relais, eine hohe Reproduzierbarkeit und Temperatur-Unabhängigkeit der Schaltpunkte durch Spannungsstabilisatoren sowie die Mitabschaltung der Steuerelektronik nach Ansprechen des Schutzes. Hierdurch gänzliche Vermeidung des Bestehenbleibens von Ruhe- oder Restströmen, die im Fehlerfall ebenfalls entladungsfähige Stromkreise bilden und dem Entladungsschutz wieder aufheben können.Another advantage is the high level of interference immunity by decoupling the control electronics from the on-board generator through an auxiliary relay, a high Reproducibility and temperature independence of the switching points through voltage stabilizers and the The control electronics are also switched off after the protection has tripped. Hereby completely avoiding the existence of quiescent or residual currents, which also form discharge circuits in the event of a fault and can remove the discharge protection again.

Ein Ausführungsbeispiel wird nachfolgend anhand der Zeichnungen Fig. 1 u. Fig. 2 näher erläutert. Es zeigtAn embodiment is shown below with reference to the drawings Fig. 1 u. Fig. 2 explained in more detail. It shows

Fig. 1 ein Blockschaltbild des Arbeitsprinzips und Fig. 1 is a block diagram of the working principle and

Fig. 2 ein komplettes Schaltbild der Schutzschaltung für eine 12-V-Anlage. Fig. 2 shows a complete circuit diagram of the protective circuit for a 12 V system.

Die Schaltung wird über den Relaiskontakt K 2 und die Sicherung e 1 von der Batterie gespeist. Die Diode D 1 bildet in Verbindung mit e 1 einen Verpolungsschutz.The circuit is fed by the battery via relay contact K 2 and fuse e 1 . The diode D 1 forms a reverse polarity protection in connection with e 1 .

Nach erfolgtem Start und Erreichen der Bordgenerator-Nenndrehzahl wird Hilfsrelais K 1 erregt. Hierdurch wird die gesamte Schaltung vom Bordgenerator entkoppelt. Über den Arbeitskontakt von K 1 und den Kondensator C 1 erhält K 2 seinen Einschaltimpuls. Das Bordnetz oder Zusatzverbraucher sind hiermit an die Startbatterie angekoppelt.After successful starting and reaching the nominal on-board generator speed, auxiliary relay K 1 is energized. As a result, the entire circuit is decoupled from the on-board generator. K 2 receives its switch-on pulse via the make contact of K 1 and the capacitor C 1 . The vehicle electrical system or additional consumers are hereby coupled to the starter battery.

Bei Stillstand des Bordgenerators fällt K 1 ab und schließt über einen Ruhekontakt C 1 mit dem Widerstand R 1 kurz. C 1 ist somit für den nächsten Startimpuls vorbereitet. Ein weiterer Ruhekontakt von K 1 koppelt einen 8V-Festspannungsregler an die Batterie. R 5, R 6 und R 7 leiten von diesem Regler eine Referenzspannung ab, die an R 6 abgegriffen wird. Der Regler versorgt außerdem den als Komparator (Vergleicher) geschalteten Verstärker V 1 mit Spannung. Die Batteriespannung wird durch R 3/R 4 auf 50% heruntergeteilt und als Istwert dem invertierenden Eingang von V 1 zugeführt. Der Sollwert (Referenzspannung) liegt am nicht-invertierenden Eingang, der über den Mitkopplungswiderstand R 8 mit dem Ausgang von V 1 verbunden ist. When the on-board generator is at a standstill, K 1 drops out and short-circuits via a break contact C 1 with the resistor R 1 . C 1 is thus prepared for the next start pulse. Another break contact from K 1 couples an 8V fixed voltage regulator to the battery. R 5 , R 6 and R 7 derive a reference voltage from this regulator, which is tapped at R 6 . The controller also supplies the amplifier V 1 connected as a comparator (comparator) with voltage. The battery voltage is divided down to 50% by R 3 / R 4 and supplied as an actual value to the inverting input of V 1 . The setpoint (reference voltage) is at the non-inverting input, which is connected to the output of V 1 via the positive feedback resistor R 8 .

Der Einstellbereich von R 6 entspricht einem Spannungswert von 10-14 V. Sinkt die Batteriespannung infolge Entladung unterhalb des eingestellten Sollwertes, kippt V 1 in die positive Sättigung. Dieser Spannungssprung steuert den Schalttransistor Tr 1 durch, und K 2 erhält seinen Ausschalt-Impuls. Die Zenerdiode Z 1 unterdrückt die am Ausgang von V 1 verbleibende Restspannung, die durch die unsymmetrische Spannungsversorgung des Operationsverstärkers V 1 bedingt ist.The setting range of R 6 corresponds to a voltage value of 10-14 V. If the battery voltage drops below the set value due to discharge, V 1 tilts to positive saturation. This voltage jump controls the switching transistor Tr 1 , and K 2 receives its switch-off pulse. The Zener diode Z 1 suppresses the residual voltage remaining at the output of V 1 , which is due to the asymmetrical voltage supply of the operational amplifier V 1 .

Abweichend von den üblichen Ausführungen bezieht die Schaltung ihre Spannungsversorgung nicht direkt vom Pluspol der Batterie, sondern über den geschlosssenen Relais-Schalterkontakt K 2. Dadurch kann die Schaltung nach abgeschalteten Verbrauchern bzw. nach geöffnetem Relais-Schalterkontakt K 2 keinen Strom aufnehmen.In contrast to the usual versions, the circuit does not draw its power supply directly from the positive pole of the battery, but via the closed relay switch contact K 2 . As a result, the circuit cannot draw any current after consumers have been switched off or after relay switch contact K 2 has been opened.

Für einen sicheren Abschaltvorgang muß die Schaltung jedoch nach geöffnetem Relais-Schalterkontakt K 2 kurzzeitig spannungsversorgt bleiben, damit die Länge des von der Schaltung abgegebenen Ausschaltimpulses über die Eigenerregungszeit des Relais-Schalters K 2 hinausgeht. Hierzu ist der Kondensator C 2 parallel zur Spannungsversorgung geschaltet, der außerdem eine eventuelle Schwingneigung des Festspannungsreglers St 1 kompensiert.For a safe switch-off process, however, the circuit must remain briefly supplied with voltage after the relay switch contact K 2 is open, so that the length of the switch-off pulse emitted by the circuit extends beyond the self-excitation time of the relay switch K 2 . For this purpose, the capacitor C 2 is connected in parallel with the voltage supply, which also compensates for any tendency to oscillate of the fixed voltage regulator St 1 .
