Abstract

The subject-matter of the invention is a charger which makes it possible to recharge gas-tight nickel-cadmium accumulators in an extremely short time, indicates the charging of a full battery or charging at unacceptably low temperatures and, using a reconditioning discharge unit, allows possible actuation of the accumulator or its discharging - in order to charge it fully again absolutely reliably and without damage, in 20 minutes.

Description

Gasdichte Ni-Cd Batterien werden immer häufiger als Energiequel­ le zum Antrieb von elektrischen Motoren angewandt; sei es im Garten-, oder Modellbau, sei es im Haushalt, oder in der Indu­ strie, aber ganz speziell zum Antrieb von Elektrowerkzeugen. Hier gibt es zu diesen Akkus keine Alternative. Kein anderes System bietet bei einer Belastung in der Größenordnung von ca. 100 I10 eine vergleichbare entnehmbare Kapazität und Zyklenfestig­ keit. Problematisch ist allerdings das Wiederaufladen dieser gasdichten Batterien, insbesondere wenn das in kurzer Zeit erfol­ gen soll, was bei der erwähnten Anwendung absolut notwendig ist.Gas-tight Ni-Cd batteries are increasingly being used as energy sources to drive electric motors; be it in gardening or model making, be it in the household or in industry, but especially for driving power tools. There is no alternative to these batteries here. No other system offers a comparable removable capacity and cycle stability with a load of the order of magnitude of approx. 100 I 10 . However, the recharging of these gas-tight batteries is problematic, especially if this is to take place in a short time, which is absolutely necessary in the application mentioned.

Die allgemein angewandte Lademethode ist Schnelladen. Unter Schnelladen versteht man das Wiederaufladen der Batterie in ca. 1 Stunde; neuerdingt werden auch kürzere Aufladezeiten (bis zu 10 Minuten) angestrebt.The common charging method is quick charging. Under Fast charging means recharging the battery in approx. 1 hour; shorter charging times (up to 10 minutes).

Es gibt allerdings keine Super-Schnell-Lademethode, die das Auf­ laden der Batterie absolut sicher und ohne erhebliche Lebens­ dauerreduzierung ermöglichen würde, ohne die Batterie vorher zu entladen, bzw. den Ladezustand zu ermitteln (s. P 39 02 368.0). Um das Ladegerät preisgünstiger herstellen zu können, wird hier auf das festeingebaute Entladeteil mit der Ladezustanderkennung verzichtet. Dafür wird eine Volladezustanderkennung realisiert. Sie ermöglicht in kurzer Zeit zu erkennen, daß eine bereits vol­ le Batterie aus Versehen wieder geladen wird.However, there is no super-fast charging method that does the job charge the battery absolutely safely and without significant life would allow permanent reduction without the battery first discharge or determine the charge status (see P 39 02 368.0). To be able to manufacture the charger more cheaply, here on the permanently installed discharge part with the charge status detection waived. A full charge state detection is implemented for this. It allows you to recognize in a short time that an already vol le battery is accidentally recharged.

Das Ladegerät ist außerdem mit einem Anschluß für ein Rekonditionie­ rungsentladegerät versehen. Wird eine Batterie auf immer gleiche Weise entladen, führt es zu einer reversiblen Inaktivierung ei­ nes Teiles der aktiven Massen, was ein Reduzieren der entnehm­ baren Kapazität zur Folge hat (auch als Memory-Effekt genannt). Mit Hilfe von diesem Gerät wird die Batterie mit einem variablen, spannungsabhängigen Strom entladen und aktiviert; es bleibt dem Anwender überlassen, ob er auf diese Weise auch eine teilentladene Batterie entlädt, um sie daraufhin absolut schonend super schnell wiedervollaufzuladen.The charger is also equipped with a connection for a reconditioning tion discharge device. A battery will always be the same Discharged in a manner that leads to reversible inactivation part of the active masses, which reduces the capacity (also called the memory effect). With the help of this device, the battery with a variable, discharge and activate voltage-dependent current; it is up to the user to decide whether to use this method a partially discharged battery discharges to make it absolutely dead gentle, super quick recharge.

Es ist zweifelsohne sinnlos eine Ladezeit anzustreben, die nicht zu einem Volladezustand führt, und dafür bewußt eine Lebensdauer­ reduzierung in Kauf zu nehmen, und dies noch unter Anwendung ei­ nes teueren Ladegerätes zu realisieren, denn die Temperatur ei­ ner profihaft (kontinuierlich) entladenen Batterie steigt auf 60-90°C und diese Batterie ist sowieso 20-90 Minuten lang nicht wiederaufladbar (s. Anl. 4).It is undoubtedly pointless to aim for a charging time that is not leads to a full charge, and consciously a lifetime to accept reduction, and this still using egg to realize an expensive charger, because the temperature A professional (continuously) discharged battery rises 60-90 ° C and this battery is 20-90 minutes long anyway not rechargeable (see Appendix 4).

Aus diesem Grund arbeitet ein Profi gewöhnlich mit mehreren Akkus. Der An. 5 ist zu entnehmen, daß ein "Vollwiederaufla­ den" der Batterie in 20 Minuten ein effektiveres Arbeiten (es werden Arbeiten und Pausen in ein Verhältnis von ca 1 : 3 gesetzt) ermöglicht als ein Aufladen in 10 Min., das lediglich zu einem ca 75%igen Ladezustand führt.For this reason, one professional usually works with several Batteries. The An. 5 it can be seen that a "full reup  the "battery works more effectively in 20 minutes (it work and breaks are set in a ratio of approx. 1: 3) enables as one charge in 10 min approx. 75% charge status.

Selbst beim Betreiben des SS-20 ohne das Re-Entladegerät, wird immerhin dafür gesorgt, daß das Laden einer vollen Batterie, sowie das Laden bei unzulässig tiefen Temperaturen angezeigt wird.Even when operating the SS-20 without the re-unloader, it will after all, ensured that charging a full battery, as well as charging at unacceptably low temperatures becomes.
