Abstract

A device is proposed for automatically detecting the electrical characteristic values of accumulators, which device is distinguished from known devices by a considerably greater universal capability. The various characteristic values, such as voltages, charging currents, capacities for example, are provided in coded form on or in the accumulators. The charger (11) contains a decoding device (21) which scans the coding of the accumulator (10) and uses the coding to form signals for switching over the charging circuit (23) of the charger. The coding consists, for example, of a mechanical matrix having projections (18) and depressions (13) on the outside of the housing of the accumulator. The decoding device (21) of the charger (11) scans the coding by means of axially sprung contact pins (19) during insertion of the accumulator into the charger, these contact pins (19) belonging to the decoding device. <IMAGE>

Description

Stand der TechnikState of the art

Die Erfindung geht von einer Vorrichtung nach der Gattung des Haupt­ anspruchs aus.The invention relates to a device according to the type of the main demanding.

Es ist ein Ladegerät bekannt (DE-OS 27 40 944), mit dem Akkumulatoren verschiedener Kenndaten, wie zum Beispiel Akkumulatorspannung, Lade­ strom und Kapazität, geladen werden können. Jeder Akkumulator weist Kontakte in einer für seine elektrischen Kennwerte charakteristischen Anordnung auf. Das Ladegerät enthält entsprechende Gegenkontakte, die mit der Ladeschaltung des Ladegerätes verbunden sind. Beim Einstecken des Akkumulators in das Ladegerät kommen die Kontakte des Akkumulators mit den entsprechenden Gegenkontakten des Ladegerätes in Verbindung, so daß der Akkumulator seinen elektrischen Kenndaten entsprechend auf­ geladen wird. Nachteilig ist bei dem bekannten Ladegerät, daß nur eine geringe Zahl von Akkumulatortypen unterschieden werden kann, wenn die Zahl der Kontakte und Gegenkontakte nicht zu groß sein soll.A charger is known (DE-OS 27 40 944) with the accumulators various characteristics, such as battery voltage, charging current and capacity, can be charged.
