Description

[Technical field]

[0001] The present invention relates to, for example, power adapters, DC power supplies including batteries, AC power supplies, and semiconductor activation devices, and in particular to power adapters, DC power supplies, AC power supplies, and semiconductor activation devices that have a cumulative effect on secondary batteries over time. [Background technology]

[0002] In general, in a rechargeable secondary battery, the active material and electrolyte of the positive and negative electrodes of the battery change due to an increase in the number of charge / discharge cycles and deterioration over time, and the internal resistance of the battery increases and the battery capacity decreases. The internal resistance of a rechargeable battery is a combination of multiple resistance factors, such as the ion conduction resistance of the positive and negative electrode separators, the charge transfer resistance of the positive and negative electrodes, and the resistance due to the delay in ion diffusion inside the positive and negative electrode active material particles. An increase in the internal resistance of the battery leads to deterioration of the battery. In addition, the battery capacity of a battery is the remaining capacity that can be charged and discharged, and a decrease in battery capacity is nothing but a decrease in charge and discharge performance.

[0003] Conventionally, the internal resistance and battery capacity of a battery have been considered important parameters for understanding the battery state, and they are monitored to check the battery state. In particular, the internal resistance value can be used to measure the individual variations in battery cells and to detect defective products during manufacturing and to determine when to replace the battery, so there is a demand for highly accurate understanding of the internal resistance as an important parameter. Similarly, there is a demand for measuring the internal resistance of general AC and DC power sources and for reducing the internal resistance.

[0004] As a method for reducing the internal resistance of a power source, the internal resistance is reduced by improving the structure and composition inside the power source. Patent Document 1 discloses a technical idea of ​​reducing the internal resistance of a battery power source by producing a non-aqueous secondary battery using a non-electrolyte solution containing a specified amount or more of a specified compound. In the technical idea disclosed in this document, the internal resistance is reduced by improving the structure and composition inside the power source, but this is not easy because the power source itself must be improved.

[0005] As described above, measures have been devised to reduce deterioration over time caused by repeated charging and discharging of secondary batteries by improving the battery itself, such as that described in Patent Document 1. However, currently, no proactive measures have been taken to suppress deterioration of existing secondary batteries caused by repeated charging and discharging. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2016-219204 A Summary of the Invention [Problem to be solved by the invention]

[0007] As described above, in the prior art, it is not easy to reduce the internal resistance of a power supply by improving its internal structure or composition. Furthermore, no new technology has been disclosed at present for reducing the internal resistance of existing power supplies.

[0008] The present invention is intended to solve the above problems, and the first objective of the present invention is to provide a power adapter, a DC power supply, and an AC power supply that reduce the internal resistance of the power supply by adding it to the outside of the power supply without changing the structure or composition of the power supply. The second objective of the present invention is to develop the idea from the above and provide a semiconductor-utilizing activation device that utilizes the principle discovered and hypothesized by the inventor as the property of semiconductors when they are not conducting to reduce noise, improve sound quality, and improve images, and further activate rechargeable secondary batteries. [Means for solving the problem]

[0009] In order to solve the first problem, the inventor tried various methods. As a result of various trials, it was discovered that the internal resistance of the power supply can be reduced by adding a light-emitting diode (hereinafter abbreviated as "LED") to the output terminal of the power supply as a power adapter so that the sum of the barrier voltages of the LEDs is equal to or greater than the power supply voltage. The present invention is based on this discovery.

[0010] In order to solve the first problem described above, a DC power adapter according to a first aspect of the present invention is characterized in that it comprises a light emitting diode array having a total forward drop voltage value greater than the power supply voltage value by a required amount, the light emitting diode array being configured to short-circuit two terminals of a rechargeable secondary battery or a DC power supply unit by connecting a plurality of light emitting diodes in series.

[0011] In order to solve the first problem, a DC power adapter according to a second aspect of the present invention is characterized in that it comprises a circuit having a plurality of parallel light-emitting diode arrays in which a plurality of light-emitting diodes are connected in series so as to short-circuit two terminals of a rechargeable secondary battery or a DC power supply unit, and the light-emitting diode arrays have a total forward drop voltage value that is greater than the power supply voltage value by a required amount.

[0012] A DC power supply device according to a third aspect of the present invention may include a chargeable and dischargeable secondary battery or a DC power supply unit, and a DC power adapter according to the first or second aspect, and may be configured such that the power supply voltage is applied from the anode side of the light-emitting diode.

[0013] In order to solve the first problem, an AC power adapter according to a fourth aspect of the present invention is characterized in that it comprises a light-emitting diode array having a total forward drop voltage value greater than the required amount than the power supply voltage value × √2, comprising a plurality of light-emitting diodes connected in series to short-circuit the respective midpoints of two power supply lines that connect the two terminals of the AC power supply unit and the two terminals of the load resistor to form a closed circuit.

[0014] Furthermore, in order to solve the first problem, the AC power adapter according to a fifth aspect of the present invention is characterized in that it comprises a circuit having a plurality of parallel light-emitting diode arrays, each of which has a total forward drop voltage value greater than the required amount of the power supply voltage value × √2, in which a plurality of light-emitting diodes are connected in series so as to short-circuit two terminals of an AC power supply unit.

[0015] In order to solve the first problem, an AC power supply device according to another aspect of the present invention may be configured to include an AC power supply unit and an AC power adapter according to the fourth or fifth aspect.

[0016] A further aspect of the present invention provides a DC or AC power supply device characterized in that a semiconductor barrier voltage sum is incorporated into a conventional DC or AC power supply at the output end of the power supply so that the sum of the barrier voltages of the semiconductors is equal to or greater than the power supply voltage.

[0017] The inventor further considered the above findings and developed the technical idea. As a result, he focused on the non-illuminated state using an LED. That is, he discovered that the so-called "non-flowing" state of an LED (or more broadly, a semiconductor in general) or a semiconductor array formed by connecting multiple semiconductors in series, which nobody had noticed before, has some effect on a rechargeable battery connected to it, which is the focus of this application.

[0018] Therefore, in order to solve the second problem above, a semiconductor-utilizing activation device according to another embodiment of the present invention comprises a battery and a semiconductor array formed by connecting a plurality of semiconductors in series, the semiconductor array having an anode connected to the + side of the battery and a cathode connected to the - side of the battery, and the semiconductor is capable of exerting an activation effect on the battery when the current of the semiconductor array is in the OFF state.

[0019] Here, "OFF state" refers to the state of the semiconductor or semiconductor array during a certain period of time until the current value goes from zero to ON, for example, the state between A and B in FIG. 4. In the conventional technical concept, no active role was recognized in this state until the current starts to flow through the semiconductor or semiconductor array. In response to this, the inventor of the present application hypothesized that the semiconductor or semiconductor array plays an active role in this OFF state, and confirmed this through various experiments and verifications, establishing a principle, and conceived of a method and mechanism that can utilize this principle industrially.

[0020] Furthermore, the inventors of the present application have further considered the above phenomenon and have discovered that simply adding the above-mentioned semiconductor or semiconductor array in the current-off state to general batteries other than rechargeable batteries or DC or AC power supply devices can instantly achieve the effects of noise reduction or sound quality improvement described below. Based on the above findings, it has been discovered that the effects of the present invention include an immediate effect on general power supplies and a cumulative effect on rechargeable battery power supplies.

[0021] Furthermore, the inventors of the present application have found that a semiconductor or semiconductor array in an OFF state repeatedly charges and discharges a rechargeable battery over a certain period of time. return As a result, the existence of the activation capacity (referred to as "cumulative activation capacity") that the cumulative activation effect has on various devices, etc. was also confirmed and verified. Based on this, the inventor of the present application was able to come up with a method and mechanism for industrially utilizing such cumulative activation capacity.

[0022] That is, the semiconductor-utilizing activation device according to the above aspect may further include a DC / AC power supply, and the semiconductor or semiconductor array may include an anode connected to the battery and the + side of the DC / AC power supply and a cathode connected to the - side of the battery, and the activation effect may be at least one of the following when a load is connected to the battery and the DC / AC power supply: an immediate reduction in noise generated by the load when an electric device is connected as the load; an immediate reduction in noise and improvement in sound when an audio device is connected as the load; and an immediate reduction in noise and improvement in video quality when a video device is connected as the load.

[0023] Alternatively, in the semiconductor-utilizing activation device according to the above aspect, the battery may be a rechargeable battery, and the activation effect may be a time-accumulated activation effect that is an effect of the semiconductor or semiconductor array on the rechargeable battery in an OFF state of the current of the semiconductor or semiconductor array that accumulates over time. In this case, the time-accumulated activation effect may be at least one of the following as a result of repeated charging and discharging of the rechargeable battery accumulating over a certain period of time: a reduction in the internal resistance of the rechargeable battery, an increase in the CCA value of the rechargeable battery, a reduction in noise on the rechargeable battery, an increase in the recovery of the current capacity of the rechargeable battery, an improvement in the sound of the audio equipment when the rechargeable battery is used as a power source for audio equipment, an improvement in the video quality of the video equipment when the rechargeable battery is used as a power source for video equipment, a difficulty in superimposing external noise on the rechargeable battery, and a reactivation of the rechargeable battery.

[0024] In addition, in the above configuration, the semiconductor is not limited to an LED but may include any type of semiconductor, and the rechargeable battery may include, but is not limited to, any of the following: general types represented by lead acid batteries, lithium ion secondary batteries, lithium ion polymer secondary batteries, nickel-metal hydride batteries, nickel-cadmium batteries, nickel-iron batteries (Edison batteries), nickel-zinc batteries, silver oxide-zinc batteries, and cobalt titanium lithium secondary batteries; liquid circulation types represented by redox flow batteries, zinc-chlorine batteries, and zinc-bromine batteries; mechanical charge types represented by aluminum-air batteries, air-zinc batteries, and air-iron batteries; and high temperature operating types represented by sodium-sulfur batteries and lithium-iron sulfide batteries.

[0025] According to the semiconductor activation device according to the other aspect having the above configuration, the chargeable and dischargeable battery is reactivated by the cumulative effect of the semiconductor being in an OFF state over time. Effect of the Invention

[0026] As described above, it has been confirmed that each embodiment of the present invention has an immediate effect that is exerted immediately after connecting to a power source, and a cumulative (time-dependent) effect that is exerted by repeatedly charging and discharging the secondary battery. As a result of the above effects, according to one aspect of the present invention, it is possible to provide a power adapter, a DC power supply device, and an AC power supply device that reduce the internal resistance of a power source by adding it to the outside of the power source without changing the structure or composition of the power source.

[0027] Therefore, it can be easily applied to existing power sources that have been used in the past. That is, by connecting the power adapter according to one aspect of the present invention to the output terminal, a large amount of power supply current can be passed. Therefore, if the power adapter of the present invention is attached to the output terminal of a battery that is nearly worn out and has an increased internal resistance and a decreased current capacity, the current capacity can be restored and increased, allowing for extended use.

[0028] Since the internal resistance of not only DC power supplies but also AC power supplies can be reduced, it is believed that the noise carried by the power supplies can be reduced, and by applying the present invention to the power supplies of audio equipment, it is possible to achieve improved sound quality.Similarly, by applying the present invention to the power supplies of video equipment, it is expected that the video quality will be improved.

[0029] In addition, a significant improvement was also seen in the CCA of battery power sources, which will be described later, and it is expected that this will make a significant contribution to electric vehicles, which are expected to see great growth in the future.

[Figure 7] FIG. 1 is a perspective view of an example of a measurement circuit of the present invention (illustrated from a photograph image actually verified). [Figure 8] FIG. 1 is a diagram showing an example of the effect of the present invention (illustrated from a photograph image actually verified). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A power adapter and a DC power supply device according to an embodiment of the present invention will now be described with reference to the drawings.

[0032] (Current-voltage characteristics of light-emitting diodes) Since the present invention uses a light-emitting diode (LED), the current-voltage characteristics of a light-emitting diode will be described first. Figure 1 shows the current-voltage characteristics of a light-emitting diode. As shown in Figure 1, a light-emitting diode has a pn junction structure using a semiconductor, and before a certain voltage (forward drop voltage) is exceeded in the forward direction from the anode to the cathode, no current flows and no light is emitted even if the voltage is increased. When the voltage exceeds the certain voltage, the current flow becomes steeper in response to the voltage increase, and the amount of electrons recombining with holes increases according to the amount of current, and the energy held by some of the electrons is released to the outside as light. The voltage V at this boundary is called the forward drop voltage or barrier voltage. The forward drop voltages of white light-emitting diodes and red light-emitting diodes are calculated to be 3.09V and 2.22V, respectively.

[0033] (Power adapter of the first embodiment) 2 is a diagram showing the basic configuration of a power adapter 10 according to a first embodiment of the present invention. The power adapter 10 is configured to form a closed circuit by attaching a light-emitting diode array 1 in the form of a serial LED row, in which red LEDs L1 to L7 are connected in series to an output terminal 3 of a 12V battery power source 2, with the anode side attached to the + terminal of the battery power source 2 and the cathode side attached to the - terminal.

[0034] In Figure 2, a secondary battery 2 In this example, a 12V battery power supply is used, and seven red LEDs are used in the light emitting diode array 1, and because the forward drop voltage (barrier voltage) value of the red light emitting diode is 2.22V, the composite barrier voltage of the power adapter formed by connecting seven red light emitting diodes 11-17 in series is approximately 15V, which is higher than the 12V of the battery power supply. In this state, the internal resistance of the power supply can be reduced, but when the power adapter of the present invention is actually applied, the internal resistance can be further reduced by adopting an embodiment such as that shown in Fig. 3 described later (details will be described later).

[0035] The light emitting diode array 1 is preferably set such that a plurality of light emitting diodes (LEDs) are connected in series and the total forward drop voltage (for example, 2.2V forward drop voltage per white light emitting diode × the number of light emitting diodes) is a predetermined amount greater than the power supply voltage (for example, 3 to 5V). For example, if the combined forward drop voltage of a plurality of red light emitting diodes is brought close to the power supply voltage of 12V, one or more red light emitting diodes may emit light due to variations or deterioration in the forward drop voltage of the light emitting diodes, so the number of red light emitting diodes may be set such that the total forward drop voltage is 3V greater than the power supply voltage.

[0036] For example, a light-emitting diode array 1 consisting of a number of red LEDs connected in series may have an anode (positive pole) of the red light-emitting diode L1 at one end connected to the midpoint (not necessarily the midpoint; same applies below) of a power supply line connecting the anode terminal of the secondary battery and the terminal of the load resistor, and a cathode (negative pole) of the red light-emitting diode at the other end connected to the midpoint of the power supply line connecting the cathode terminal of the secondary battery and the terminal of the load resistor, so that the current of the secondary battery flows in the forward direction through the red light-emitting diodes L1 to L7.

[0037] The light-emitting diode array 1 is preferably configured by arranging seven red light-emitting diodes L1 to L7 in a row on a substrate (not shown), connecting the seven red light-emitting diodes L1 to L7 in series by pattern wiring formed on the substrate, and providing two terminals for connection to midpoints of two power supply lines.

[0038] In the above example, if a white LED is used instead of the red LED, the total forward voltage drop of the multiple LEDs (forward voltage drop per white LED 3.09V x number of LEDs) is 3.09V x 3.09V, which is the same as the voltage drop of the secondary battery. 2 It is preferable to set the number of white light emitting diodes so that the output voltage is 3 to 5 V higher than the maximum output voltage value of the white light emitting diode array. Therefore, in this case, it is preferable that the light emitting diode array is configured by connecting five white light emitting diodes in series.

[0039] (Modification of the first embodiment) The present invention can be applied to reducing the internal resistance of not only DC power supplies but also AC power supplies. 2 In the secondary battery 2 It is possible to have a configuration in which the power supply is replaced by an AC power supply.

[0040] A power adapter, which can also be used to reduce the internal resistance of an AC power supply, is configured as a circuit having a total forward drop voltage value that is greater than the power supply voltage value × √2, in which a number of light-emitting diodes are connected in series to short-circuit the midpoints of two power supply lines that connect the two terminals of an AC power supply device and the two terminals of a load resistor to form a closed circuit.

[0041] By attaching a power adapter to an AC power source, the internal resistance of the AC power source can be reduced, and it is believed that the noise carried by the power source can be reduced, and by applying the present invention to the power source of audio equipment, it is possible to achieve an improvement in sound quality.Similarly, by applying the present invention to the power source of video equipment, it is expected that the video quality will be improved.

[0042] A reduction in the internal resistance of the power supply means a reduction in the power supply impedance, making it particularly difficult for external noise to be superimposed on the AC power supply. By attaching the power adapter of the present invention to the power supply of audio equipment, extremely clear sound reproduction can be achieved.

[0043] (Power adapter of the second embodiment) 3 is a diagram showing a basic configuration of a power adapter 10A according to a second embodiment of the present invention. The power adapter 10A is configured by an arrangement in which a light-emitting diode array 1A according to the second embodiment, in which a plurality of series LED rows are connected in parallel, is inserted and connected between a power output terminal 3 (not shown) and a power load 6. More specifically, the two power supply lines that connect two terminals (not shown) of a battery or a DC power supply device and two terminals (not shown) of a load resistor 6 to form a closed circuit are short-circuited at their respective midpoints (not limited to the midpoints) by an LED row (light-emitting diode array) in which a plurality of light-emitting diodes (LEDs) are connected in series, and the light-emitting diode arrays are arranged in parallel, forming a circuit having a total forward drop voltage value that is a predetermined amount greater than the power supply voltage value.

[0044] figure 2 Secondary battery shown in 2 Since the output voltage and output current of the DC power supply are larger than those of the DC power supply 10A, the power adapter 10A is configured so that the total forward drop voltage value of the light-emitting diode array, which is formed by connecting multiple light-emitting diodes (LEDs) in series, is greater than the power supply voltage value of the DC power supply 10A by a predetermined amount, and by arranging multiple light-emitting diode arrays in parallel, the current from the DC power supply is distributed to the multiple light-emitting diode arrays.

[0045] (Modification of the second embodiment) The second embodiment can also be applied to reduce the internal resistance of an AC power supply. That is, in Fig. 2, the DC power supply device is replaced with the AC power supply. In the case of an AC power supply, it was confirmed by verification that it is sufficient to use a series LED string in which the number of LEDs connected in series is such that the composite barrier voltage of the series LED string (light emitting diode array) is √2 times or more the AC power supply voltage.

[0046] In other words, the power adapter according to the second embodiment of the present application, which can also be applied to reducing the internal resistance of an AC power supply, is configured with a circuit having a plurality of parallel light-emitting diode arrays, each of which has a total forward drop voltage value that is greater than a predetermined amount than the power supply voltage value × √2, by connecting a plurality of light-emitting diodes in series so as to short-circuit the respective midpoints of two power supply lines that connect two terminals of an AC power supply device and two terminals of a load resistor to form a closed circuit.

[0047] By attaching a power adapter to an AC power source, the internal resistance of the AC power source can be reduced, and it is believed that the noise carried by the power source can be reduced, and by applying the present invention to the power source of audio equipment, it is possible to achieve an improvement in sound quality.Similarly, by applying the present invention to the power source of video equipment, it is expected that the video quality will be improved.

[0048] A reduction in the internal resistance of the AC power supply means a reduction in the power supply impedance, which in particular makes it difficult for external noise to be superimposed on the AC power supply, and by attaching the power adapter of the present invention to the power supply of audio equipment, it is possible to reproduce very clear sound. Similarly, an increase in the AC power supply voltage increases the efficiency of additional equipment, which is thought to have an effect on improving sound quality and images.

[0049] (The internal resistance of the secondary battery, DC power supply, and AC power supply, and whether or not a power adapter is attached) The internal resistance of the above-mentioned chargeable and dischargeable secondary battery, DC power supply device, and AC power supply device can be measured by an internal resistance measuring device. 2 In this circuit, two terminals (probes) of an internal resistance measuring device are connected between the light emitting diode array 1 and the load resistor 4 so as to short-circuit the two power supply lines.

[0050] In the state shown in Figure 3, the internal resistance of a 12V36A (5-hour rate) car battery power source 5 was actually measured using an internal resistance measuring device. PlaceIn an example measured using a power adapter according to one embodiment of the present invention (9 red LEDs connected in series in 7 parallel rows, 10 white LEDs connected in series in 10 parallel rows, totaling 1,441 LEDs), the resistance was 10.41 mΩ when the power adapter according to one embodiment of the present invention was attached, but it was reduced to 8.6 mΩ when the power adapter according to one embodiment of the present invention was attached.

[0051] 5, a DC motor 54 was connected to the battery or DC power supply 51 and driven, and the noise superimposed on the wiring to the DC motor 54 before and after connecting the power adapter 52 of the present invention was observed by an oscilloscope 55. In FIG. 5, a 6V DC power supply was used, and ten 6V DC motors and ten white LEDs 53 were connected in series, and three of these ten parallel connections were connected in parallel to form the power adapter 52, which was then connected to the power supply.

[0052] Figure 6 shows the power adapter 52 6 is an actual perspective view (a sketch of a photographic image actually verified) of FIG. 6. Ten white LEDs are connected in series on one board 62 in FIG. 6, and LED boards 62 with ten rows connected in parallel are connected in parallel in three layers. FIG. 7 is a perspective view (a sketch of a photographic image actually verified) of the block diagram in FIG. 5 as an actual measurement circuit, in which a DC motor 73 and the power adapter 3 of the present invention are connected to a DC power supply 71. A probe 74 of an oscilloscope (not shown) is connected to the wiring of the DC motor 73 to observe noise superimposed on the wiring of the DC motor 73.

[0053] Figure 8A is an oscilloscope observation diagram (a photo of an actual verified image) of the noise state of the wiring to a DC motor before the power adapter of the present invention is added, and Figure 8B is an observation diagram (a photo of an actual verified image) when the power adapter of the present invention is connected.

[0054] As can be seen from Figure 8, the peak value of noise 82 superimposed on the motor drive current waveform 81 is clearly reduced to less than one third. This is believed to be evidence of the sound quality improvement effect or image quality improvement effect according to the embodiment of the present invention described above. The internal resistance improvement effect and noise improvement effect described above are immediate effects that appear immediately when the power adapter of the present invention is connected to a power source.

[0055] On the other hand, when a rechargeable battery is connected to a power adapter according to an embodiment of the present invention and charged and discharged 5 to 6 times, the reduction effect is further increased. For example, when a power adapter with 50 red LEDs (barrier voltage 2.22V) connected in parallel according to an embodiment of the present invention is connected to a 1.2V rechargeable battery, the internal resistance is significantly reduced to 110.4mΩ from the internal resistance of 461.9mΩ before connection. This is considered to be a cumulative effect brought about by repetition over a certain period of time, in contrast to the immediate effect mentioned above.

[0056] In addition to internal resistance, CCA is another indicator of battery performance for car batteries. CCA stands for Cold Cranking Amperes, and is the battery standard used in the United States. It is an indicator of how much electricity the battery can output when it is discharged for 30 seconds at -18°C until the terminal voltage drops to 7.2V.

[0057] The effect of the power adapter according to one embodiment of the present invention is to reduce the battery ToWe have verified the application of the present invention. The CCA was measured and compared when the 1.441 power adapters according to the embodiment of the present invention were added to the 12V36A battery power source for a car and the battery was charged and discharged 5 to 6 times, and when the adapter was not added. The internal resistance before the power adapter was added was 240, and the CCA after the power adapter was added was 384, which was a clear and significant improvement. As described above, it is believed that adding the power adapter of the present invention and repeatedly charging and discharging the battery can provide a cumulative effect that can bring about a cumulative improvement in the charge and discharge battery, and it was found that the power adapter of the present invention can provide both immediate and cumulative effects.

[0058] As is clear from the above various experiments and verifications, the power adapter according to one embodiment of the present invention can reduce internal resistance.

[0059] A reduction in the internal resistance of the power supply means a reduction in the power supply impedance, making it particularly difficult for external noise to be superimposed on the AC power supply. By attaching the power adapter of the present invention to the power supply of audio equipment, extremely clear sound reproduction can be achieved.

[0060] (Modification of the third embodiment) The third embodiment of the present invention is a technical idea developed from focusing on the so-called "non-flowing" state of a semiconductor or semiconductor array (when an LED is used, the non-illuminating state). In other words, the main focus of the third embodiment of the present application lies in the discovery that a semiconductor or semiconductor array has some effect on a rechargeable battery connected to it, something that no one had noticed before.

[0061] 4 is a conceptual diagram for explaining the OFF state in a current-voltage characteristic diagram of a light-emitting diode according to the third embodiment of the present invention. In the diagram, "A" indicates the start point when a voltage is applied (i.e., the initial state point when the current value is zero), and "B" indicates the point when the current value substantially rises (indicating a value at which a significant difference from zero is recognized) among the timings when the current value changes over time when a voltage is applied.

[0062] As shown in Fig. 4, "OFF state" refers to the state of the semiconductor or semiconductor array during a certain period of time until the current value goes from zero to (substantially) ON, for example, the state between A and B in Fig. 4. In the conventional technical concept, this state before the current starts to flow through the semiconductor or semiconductor array has not been recognized as having a positive role, whereas in the third embodiment of the present application, attention is focused on the cumulative effect that the semiconductor or semiconductor array in this OFF state has on the rechargeable battery over a certain period of time. Furthermore, it was discovered that this effect has the ability to activate various devices, etc., and based on this, a device that generates industrial utility value was created.

[0063] In other words, if the semiconductor or semiconductor array is an LED or LED array, this OFF state is a state in which no light is emitted and on the surface it appears that nothing is happening. However, as a result of various repeated experiments and verifications, the inventor of this application hypothesized that in this OFF state, where nothing is apparently happening, some kind of physical / chemical phenomenon is occurring between the semiconductor and the rechargeable battery.

[0064] Based on this hypothesis, we conducted demonstration experiments using various automobiles and audio equipment, and observed that the terminal voltage of rechargeable secondary batteries for automobiles rose from 13.8V to 14.8V, improving fuel efficiency, which was likely due to improved engine ignition efficiency. In other words, we concluded that the above hypothesis is correct, and that this physical / chemical phenomenon is related to the effect of revitalizing rechargeable batteries, or in other words, rejuvenating them.

[0065] Therefore, the present inventor has realized the third embodiment of the present invention as a semiconductor-utilizing power source activation device, and as one form of the device, a power adapter and a (DC / AC) power source device, in order to utilize the device industrially. In terms of technical concept, the semiconductor-utilizing activation device according to the third embodiment is configured to include a rechargeable battery, a semiconductor or semiconductor array having an anode connected to the + side of the rechargeable battery and a cathode connected to the - side of the battery, and a means for accumulating over time the activation effect that the semiconductor or semiconductor array has on the rechargeable battery when the current of the semiconductor or semiconductor array is in the OFF state.

[0066] With the above configuration, the chargeable / dischargeable battery is reactivated by the cumulative effect of the OFF state of the semiconductor or semiconductor array over time. Note that the semiconductor is not limited to an LED in the above description, but may include any type of semiconductor. In other words, it is presumed that the property of having an activating effect on the chargeable / dischargeable battery described above can be applied to semiconductors or semiconductor arrays in general. Therefore, the semiconductor does not have to be the LED described above. The reason why an example using an LED is described above is that the ON state can be visually confirmed.

[0067] In addition, rechargeable batteries may include, but are not limited to, any of the following general types represented by lead acid batteries, lithium ion secondary batteries, lithium ion polymer secondary batteries, nickel-metal hydride batteries, nickel-cadmium batteries, nickel-iron batteries (Edison batteries), nickel-zinc batteries, silver oxide-zinc batteries, and cobalt titanium lithium secondary batteries; liquid circulation types represented by redox flow batteries, zinc-chlorine batteries, and zinc-bromine batteries; mechanical charge types represented by aluminum-air batteries, air-zinc batteries, and air-iron batteries; and high temperature operating types represented by sodium-sulfur batteries and lithium-iron sulfide batteries.

[0068] As described above, when the present invention is actually applied, various variations are possible, but they are all included in the technical concept of the present invention. [Industrial Applicability]

[0069] According to the present invention, the effect of reducing the internal resistance of the power source by being added to the outside of a rechargeable secondary battery or a DC power supply device (power source) without changing the structure or composition of the power source is achieved. Therefore, by attaching the power adapter of the present invention to the output terminal of a secondary battery or the like that is nearing exhaustion and has increased internal resistance and reduced current capacity, the current capacity can be restored and increased, allowing for extended use.

[0070] The inventor connected the power adapter of the present invention to car batteries, especially used batteries that were difficult to charge, and confirmed that most of them could be put to practical use again, probably because the internal resistance was reduced. In addition, when the adapter was connected to batteries in a slightly weakened state, all of them were able to be revived with CCA values ​​similar to those of new batteries. As shown in the above example, the present invention has great potential for use in the fields of transportation and power machinery that use batteries. Furthermore, by applying it to the power source of audio equipment, it is possible to improve the sound and reduce noise, and a wide range of industrial applications are considered.

[0071] Furthermore, according to the third embodiment, the OFF region of a semiconductor or semiconductor array that has not been given much attention up until now is actively utilized to revive a chargeable / dischargeable battery, in other words, to have the effect of rejuvenating it, so it is expected that there will be enormous applicability in various industries and industrial infrastructures, including solar cells.
