Abstract

Abstract Translated from German Bei einer derartigen Schaltung mit einem Spannungsdetektor, der ein Signal abgibt, sobald eine den Batteriezustand charakterisierende Größe einem Grenzwert passiert, sind vorgesehen: Mittel zum wiederholten Trennen der Batterie (4) von Ladungsspeicher (15) für die Stromversorgung enthaltenden Schaltungsteilen sowie von in ihrem Stromverbrauch variablen Teilen (1) der zur Erzeugung von Stimulationsimpulsen dienenden Schaltungsteile für jeweils einen vorgegebenen Zeitraum, Mittel zum Verbinden der Batterie (4) mit einem festen Lastwiderstand (9), dessen Wert groß gegenüber dem Innenwiderstand (R i ) der Batterie (4) ist, innerhalb des Zeitraums, wobei der Strom durch den Lastwiderstand mindestens mittelbar die den Batteriezustand charakterisierende Größe bildet, und Mittel (16) zum Speichern des von dem Spannungsdetektor (8) abgegebenen Signals. In a circuit of this type with a voltage detector which emits a signal as soon as a quantity characterizing the battery state passes a limit value, the following are provided: means for repeatedly disconnecting the battery (4) from charge stores (15) for circuit parts containing the power supply and in terms of their current consumption variable parts (1) of the circuit parts used to generate stimulation pulses for a predetermined period of time, means for connecting the battery (4) to a fixed load resistor (9), the value of which is large compared to the internal resistance (R i ) of the battery (4) , within the time period in which the current through the load resistor forms the quantity characterizing the battery state at least indirectly, and means (16) for storing the signal emitted by the voltage detector (8).
