Description

The invention relates to a method for regenerating a voltage source by means of electric energy supplied to the primary element, as well as to an apparatus for implementing this method.

Primary cells, otherwise primary sources of low voltage in everyday life, are used in a variety of devices, devices, or devices where electrical power supplies serve to supply these devices, devices, or devices. Primary sources of this type of voltage include, for example, manganese, alkaline, zinc carbon, or other elements, all of which are characterized by the fact that after a certain time of use, their output poles display such low voltage that their intended use is no longer possible. Along with the weakening output voltage due to electrochemical changes in such primary cells, changes in the internal resistance of the cells are followed, as well as the power of the cells in parallel with the nominal voltage. A typical position is a non-charged primary cell with an initial voltage of 1.5 V. This type of cell is considered to be used when the voltage is between approximately 1 and

1.2V alternating.

As a rule, this type of used element is usually supplied, without much thought, to normal household litter or industrial litter, and the constituents of the material and chemical structures of these elements are highly hazardous to protected natural environments. Recently used batteries of this type have started to be assembled in specially equipped areas and their components are brought under control, often those elements that have already been considered used are inspected, if they are, within the voltage range of 1 to 1.2 V, the components of the batteries are completely usable. It is assumed that during operation the variable voltage of the cells will be detected and consequently the reduction of the current supply capacity from them (cells) will be detected only during the internal reaction of the usage of the batteries by sliding the usage time. There are various ways in which primary voltage sources, the use of which is already in the foregoing reasoning, are reprocessed so that they are capable of retaining the set power for a further period of time. All the methods known to date have such a drawback that they do not carry out the actual regeneration at all or do it in a very unreliable way.

It is an object of the present invention to provide a method and apparatus for realizing it which is capable of regenerating to primary voltage sources so that their power is close to that of consumption, to reach the level of the primary voltage source before it is used. accordingly, production must be such that the marginal cost of production is eliminated.

The method differs in its task in that the regenerated voltage source hits a defined amplitude and a fixed number of pulses within a defined time interval with a significant periodically applied voltage pulse.

The advantage of the method according to the invention is that the primary voltage source becomes recoverable, that the effort is actually made to achieve the power output as if it has not been used before, the primary voltage source level is reached as before use. This method according to the invention has the further advantage that it is possible to regenerate the primary voltage sources several times after multiple discharges without further reaching the primary power after each regeneration. This technique achieves the greater advantage that material savings also reduce the supply problem and replace primary voltage sources only after multiple regeneration, when the actual primary voltage sources begin to observe internal, anti-parabolic interference. Positive results of this method include the improvement of this type of Voltage pulse when it shows a short rise time or a short slope time, which means the operation of the sloped Voltage pulse sides, which allows for a substantial increase in the regeneration effect.

The most convenient pulse lengths are between 10 s and 2x10 s, as the pulse lengths, which are variable from the elements being regenerated, are also adjustable depending on other parameters.

Also, the advantage is that it is variable and located in the best area from where.

such that Voltage pulses may be selected, for example, for path2 up to 200 Hz, and

Finally, it is positive that the regeneration current, for example, in the range from 5x10 ² A to 15 A is regulated. Therefore, it is possible, for example, to provide a firm determination of the regeneration current in this field, which means the constant regeneration of the pulsing current and the varying Voltage pulse amplitudes of primary voltage sources dependent on the regeneration state, but it is also the reset is left to self-process at a constant voltage voltage pulse at the previous firmly set amplitude.

Device for regeneration of voltage sources to primary Voltage source form, which has a constant voltage source of low electrical impedance due to the voltage dissipated by Voltage, characterized by the constant voltage signal being supplied by the tactical generator rhythm switch and the output of the switch , is connected to one of the poles of the voltage source that is being regenerated. The essential advantage of a device is that it can be simply made from existing, affordable, expensive components in such a way that the device generates negligible costs overall, thus enabling its use in private and business applications. As a rule, this type of device can normally be used wherever there is a mains power supply that supplies primary energy for its use so that no necessary switching technique is required for the electrical connection, which means that with normal use of a voltage transformer and / or power supply it would be possible to return from the network to its original position. Preferably, the triggering mechanism comprises an actuator for determining the amplitude of the voltage pulses and, most preferably, a regulating device for regulating the regeneration current, generally the latter must steadily adjust its amplitude of the modified voltage pulses depending on the degree of regeneration of the primary voltage source.

The regulating characteristic of the regulator may best be determined by the degree of regeneration of the internal state of the voltage source, but it is also possible to choose another regulating characteristic if the latter is necessary or desirable due to the regenerated voltage source and a special regeneration characteristic is necessary or desirable.

Finally, another advantage is the regeneration time interval of the voltage source being regenerated. Through this interval, the adjustable delay circuit is adjusted or set so that after completion of the regeneration process, the quasi regeneration is terminated automatically, meaning that the primary voltage source is off.

The invention is described with reference to the following schematic drawings of an exemplary embodiment.

- tactical (pulse) generator,

- output switching device,

- input activation device,

The device for implementing this method is first explained in the block diagram of FIG. 1. Low Resistance Constant Voltage Source 13 may be met, for example, through a network connection with properly selected parameters so that a voltage source can be connected to the input at any time by a suitable and best adapted network change. The constant voltage source 13 provides a constant voltage or a constant voltage signal 3 to the input 7 of the switch 4 in a known manner. the mechanism 11, which also operates in concert with the switch 4, is adjustable depending on the pulse length. The pulse length of the pulse sequence 8 is from 10 ~ ^J to 2x10 ^{_: l} s.

The actuator 11 can also be provided with an actuator or regulator for regulating the regeneration current in the range of 5 x 10 ' ² A to 15 A.

The tactical oscillator 5 is adjustable such that it adjusts the voltage pulse frequency of the voltage pulse stream 8, for example, in the range of 2 to 200 Hz. The delay circuit 12 is coupled to circuit breaker 14 such that the voltage pulses at output 6 of tactical switch 4 at pole 9 can connect to regenerable voltage source 1. Another pole 10 is connected in a known manner to regenerable voltage source 1 through another pole of DC voltage source 13 the mass of the existing trigger.

The delay circuit 12 may be arranged to be controlled such that, in a known manner, the regeneration process, i.e. the supply of a voltage pulse sequence 8 to the regenerable voltage source 1, may flow within a known time interval. When the end of the time interval is reached, the circuit breaker 14, which is closed at the time interval pressure, opens so that the automatic power supply pulse sequence 8 of the regenerated source 1 is disconnected.

It is also known that the device is substantially configured so that the regeneration current in dependence on internal changes in the regenerated voltage source 1 remains constant (constanta) (current constant corresponding to regeneration), but also the possibility of regulation or also the ability to regulate constant variations in regenerated voltage. the internal state of source 1 during the regeneration process.

FIG. 2 shows the device according to FIG. 1, a single view of its technical connection is shown here.

The supply voltage of the device follows the transformer 15 connected to the mains voltage supply. Two capacitors 16 are connected to one pole of the secondary transformer 15 and two diodes 20 are connected to the other pole, which together form a twin voltage connection. In this way, a low impedance DC voltage source is formed for supplying the following functional degrees of the device:

The formation and formation of the rapidly falling pulses necessary for a high regeneration effect occurs in a tactical oscillator or pulse generator 5. This acts as an asymmetric multivibrator with transistors 17 and 18 and generates and forms the required pulses with a pulse frequency of 2-5 Hz. Further down the pulse circuit, this electronic switch 4 is introduced and secured. These voltage pulses are then routed to the part of the unit where they can enter the regenerable elements. Due to the device and regeneration, the protection of the disposed elements or the voltage source 1 can be triggered by the device switch-off automation 19, which limits the regeneration or fast-loading process at certain times, e.g. If necessary, the regeneration or fast-loading process can be activated at repeated times at the selected time by repeatedly pressing the time switch 21.

FIG. Figure 3 shows the voltage source output voltage flow versus time after discharge at a load impedance of 6 ohms, about 250 mA, respectively. After about 12 hours. the voltage of voltage source 11 varies from 1.5 V to 1.2 V. The 250 mA meets the electricity demand of the incandescent lamp and can also be used in a pocket lighter. The first discharge process of the voltage source 1 is illustrated in FIG. 3 on curve A. This is how the unused, new voltage source operates 1.

After a single regeneration period of about 20 min. using the invention and the device, the rated voltage of the regenerated voltage source flows again at about 1.5 V. Further loading of the regenerated voltage source 1 while retaining the previously determined load parameters after 12 hours. shows a curve B which is almost equivalent to the primary load curve A. During a further regeneration using the method and apparatus of the invention, a nominal secondary voltage of about 1.5 V is passed again over a period of 20 minutes, retaining the previous load parameters. little difference from curves A and B.

Studies show that the primary voltage sources used maintain a good quality of regeneration at least 10 times, without significant power losses. The invention makes it possible to reverse the chemical or electrochemical reactions inside the primary voltage source 1. The normal electrochemical reaction in a closed electrical user is such that a precipitate is deposited on the electrodes which has an insulating effect. Thanks to the method of the invention and the device of the invention, the electrodes are released from the insulating deposits so that their capacitance is restored for a long time. FIG. 4 illustrates the housing of a device for multiple regeneration of a voltage source 1. It is possible here to regenerate the various voltage elements individually or together.

It can be noted that the method of the invention and the device of the invention can be used not only for regeneration of primary voltage cells 1 but also for extremely fast charging of secondary voltage sources, meaning that all types of batteries without regeneration by inventive principle or without time and certain pulse width, amplitude, frequency, and the like would be emitted.

This method according to the invention and the device implementing it are very efficient and suitable for use in charging secondary voltage sources.
