Abstract

A method and a device (10) are proposed for the regeneration of voltage sources (11) in the form of primary cells (primary elements), by means of electrical energy which is supplied in the form of a DC voltage. In this case, the voltage source (11) which is to be regenerated has applied to it over a predetermined time interval voltage pulses (18) which are applied essentially cyclically, have an amplitude which can be predetermined and have a pulse length which can be predetermined. The DC voltage signal (13) required for this purpose is supplied from a low-resistance DC voltage source (23). The voltage pulse sequence (18), which is applied to one pole (19) of the voltage source (11) which is to be regenerated, is produced in a pulsed switching device (14) by means of a pulse generator (clock generator) (15). <IMAGE>

Description

Technical field

The invention relates to a method of regenerating voltage sources converted as primary elements by the supplied electric power, as well as to a device for carrying out such a method of regeneration.

Screeds of the prior art

Primary elements, for example primary voltage sources, are inherently inherent in daily life and are used in some of the following:,, 1 c c c,,,,,,,,,,... V.. to serve there as a source of electrical voltage for the power supply; t r o j o v, z a r i a d e o a p r 1 p r a v k o v. Primary voltage sources of this kind are, for example, manganese, alkaline, zinc-carbon or others. elements, all of which are characterized by having only a low voltage after a certain working time of the output pole and so that the prescribed operation of the connected appliances is not possible.

Along with the decreasing output voltage, the internal resistance of the elements changes by electremic changes inside such primary elements, so that the power of the elements decreases in parallel with the nominal voltage. Typically, the primary element, for example, has a voltage of 1.5 V in the unladen, original state. An element of this kind is considered to be worn out when the voltage has dropped to about 1 to 1.2 V.

Usually, the elements thus scrapped are disposed of with normal household and industrial waste without consideration, which is largely unsuitable or dangerous due to the environmental and material composition. Recently, these spent elements are collected at separate collection points and are intended to utilize a portion of them, but often the element is considered to be bred in the sense described above when the cioslalml has a lower voltage limit. 1 to 1.2 V, however, the portions of the element are actually quite intact.

It should be noted that, during operation, the varying voltage of the element and the associated decrease in the ability to supply current is due solely to the reactions occurring within the element during the period of use.

There have been various attempts, or alternatively, methods which, in the above-described sense, should have used up the primary voltage sources to revive in order to be able to deliver the prescribed power for a further period of time. All the prior art processes have such a drawback that they do not allow a truly effective regeneration or allow it in a very small way.

It is therefore an object of the present invention to provide a method and apparatus of the initially mentioned kind, allowing the regeneration of primary voltage sources in a manner that nearly achieves the power of unused power. m a r y c: h z. d r o .j o v n a five. The device is intended to be simple and cost-effective to make or to produce, so that at low production rates it is possible to carry out a wide range of applications.

The problem is solved by providing the voltage source to be regenerated with a predetermined amplitude and a predetermined number of pulses during a predetermined period of time.

In essence, the method of the invention is essentially that the primary voltage source can be regenerated as we are trying to do so, i. it is indeed possible to achieve almost a power supply that has so far been achievable by unused, unused primary voltage sources. In addition, the process according to the invention has the advantage that it is also possible. \ ·· -. ·; L _ · ..; Λ ^ <ςιΐ ·.

Moreover, in this way it is advantageously achieved that, in addition to saving raw materials, the problem of defecation is also alleviated and the primary voltage source must be collected only after repeated regeneration when the actual internal, irreparable destruction of the primary voltage source is detected.

In the method, the voltage pulses are a short rise time, optionally

In an advantageous arrangement, they are adapted to run, which means that they are steep voltage pulses.

The pulse times are preferably between 10 &lt; ^{3 &gt;} s and 2 * 10 &^lt; -1 &gt;: ⁵ s, the pulse time depending on the regeneration element being variable, also depending on other parameters.

Also preferred is. the variable frequency of the voltage pulses can be selected and used in the preferred range from 2 to 200 Hz.

Finally, it is also advantageous if the regeneration current can be set in the range of 5x10 ^-3. A to 15A. It is possible to set the regeneration current in this range, for example, fixedly,

You are the one measuring the voltage 1. The measuring voltage is transmitted by the clock pulse generator clocked by the switching device, the output of the switching geWgSi

The device which delivers the pulse sequence of the voltage can be coupled to &quot; &quot; &quot; 2 &quot;

with one pole of the voltage source to be regenerated ..

The advantage of the device is essentially that it can be built in a simple manner and essentially made of cost-effective components, so that the device has a substantially low total cost of purchasing raw materials and can therefore be used in bulk in almost all private and industrial areas. Typically, this equipment will draw the necessary primary energy from all existing networks for its intended operation, so that the necessary adaptation does not require costly engineering measures for the wiring, which means that pointed voltage transformers or power supplies can be routinely used.

Advantageously, the switching device has an action device for determining the pulse voltage amplitude and a control device for regulating the regeneration current if it is to be set constant at varying voltage pulse amplitude as a function of. on the stage. regenerating the primary source e., the voltage to be regenerated.

The control characteristic of the control device may be adapted to varying internal resistance, depending on the degree of regeneration of the voltage source, but it is also possible to select a different control characteristic if necessary or appropriate for the type of regenerated energy source and if a particular regenerative character is necessary or required. first s t i k y.

Finally, it is advisable to set or predetermine the regeneration time interval of the voltage source to be regenerated by an adjustable timer for this time period so that upon completion of the regeneration process the regeneration is automatically terminated, which means that the primary voltage source is switched off.

The timer 22 can be made adjustable so that the regeneration process can be in a predetermined manner, i. that the connection of the voltage source 11 to be regenerated to the pulse voltage sequence 1.8 takes place at a predetermined time interval. When the end of the time interval is reached, the switch 24, which has been closed by pressing the time interval button previously, is opened so that the voltage pulse sequence 1.8 is automatically cut off to the regenerated power supply 11.

Let it be pointed out that the device 18 is essentially designed so that it is possible for it to be able to set a constant regeneration current depending on the internal resistance of the regenerated voltage source 1.1 (constant current charging or regeneration), but also can be controlled as needed or independently controlled during the regeneration process according to the varying internal resistance of the regenerated power supply 11.

The formation and formation of pulses with steep sides required for a highly effective regeneration effect occurs in the clock pulse generator or pulse transmitter 15. This operates as an asymmetric multivibrator with transistors 27 and 28 and generates and forms the desired pulses with a pulse frequency of 2-5 Hz. Further pulse shaping circuits are then amplified and fed to the electronic switch 1.4. Thereafter, these voltage pulses lead to that part of the elements which the device elements of the device and possibly the device into which s and m and can be inserted. j e r g en e r o t t.
