Description

The present invention provides a battery monitoring life extension method for maintaining the quality and extending the life of the battery by performing necessary life extension measures while monitoring the battery (lead storage battery) used as an emergency (backup) power source in real time. It relates to a battery monitoring life extension device used therefor.

2. Description of the Related Art Conventionally, in many facilities such as commercial facilities, public facilities, factories, and hospitals, an uninterruptible power supply or the like equipped with a battery is installed as an emergency (backup) power supply. This emergency power supply is prepared so that it can supply electric power in place of the commercial power supply when an abnormal situation such as a power failure occurs in the commercial power supply, and plays a very important role in terms of safety. Therefore, the battery must always be sufficiently charged so as to be able to cope with any power outage accident. Therefore, the emergency power supply is connected to the load in parallel with the commercial power supply, and the battery is charged from the commercial power supply with a small current, usually called float charge, and maintained in a fully charged state. However, it is known that a battery that is continuously float-charged gradually deteriorates and eventually reaches a state where it cannot supply sufficient power to the load. Therefore, it is desirable to carry out inspections on a daily basis, but since this takes time and effort, regular inspections are usually carried out once every six months or once a year. Even in that case, there is a problem that if the number of batteries increases, a large amount of labor costs are incurred. In addition, the battery deteriorates due to aging even if it is used infrequently, so it is replaced with a new one every time a certain period of time (for example, 6 to 10 years) elapses after installation and then disposed of. In such periodic replacement, even a battery that maintains good performance (no deterioration has occurred) is replaced, which is extremely uneconomical and lacks resource saving. In particular, when all the batteries installed in communication devices, control devices, etc., are to be replaced regularly, the number of target devices is enormous, and the purchase, transportation, replacement and collection of batteries requires a great deal of cost and labor. There is also the problem of requiring
Therefore, for example, in Patent Document 1, a remote local controller and a system controller monitor and control a power storage system via a communication network, A storage battery monitoring method and a monitoring controller have been proposed. Further, Patent Document 2 proposes a battery deterioration monitoring system that automatically measures the deterioration state of a battery for backup power supply and performs remote monitoring.
On the other hand, in a lead-acid battery (battery), which is suitable for use as an emergency power source, repeated charging and discharging causes a chemical reaction between the sulfuric acid in the electrolyte and the lead in the electrode plate, resulting in a crystallized nonconductor on the negative electrode surface. Lead sulfate (PbSO ₄ ) forms a film and adheres to the electrode plate, causing a phenomenon (sulfation) in which the electrochemical activity of the electrode is lost, which causes deterioration of the battery. Therefore, by removing the film of lead sulfate adhering to the electrodes of the lead-acid battery, it is possible to extend the life of the lead-acid battery. For example, Patent Document 3 proposes a method for regenerating a lead-acid battery by dissolving, reducing, or decomposing and reducing the film of lead sulfate produced by the sulfation phenomenon of the lead-acid battery, and a lead sulfate film-removing apparatus used in the method. ing.

However, in the remote monitoring as disclosed in Patent Documents 1 and 2, when deterioration (or abnormality) of the battery occurs, it is notified by various notification means, and the deteriorated battery is not left unattended until periodic replacement. Since the battery is replaced with a more durable battery, the burden of monitoring and inspection work is reduced, but the life of the battery cannot be extended. On the other hand, Patent Document 3 is intended to regenerate a lead-acid battery that has already been judged to have reached the end of its life and has been discarded (recovered), and does not attempt to extend the life of a lead-acid battery (battery) in use.

This is intended to maintain the quality and extend the life of the battery 11 by taking necessary life-prolonging measures while monitoring.
Here, the battery 11 has a plurality of cells (unit batteries) 12 connected in series, but the configuration of the battery is not limited to this, and a plurality of cells are connected in series and in parallel. may be connected in parallel or may be connected in parallel.

First, as shown in FIG. 1, the battery monitoring life extension device 10 includes characteristic data acquisition means 13 which is connected to each cell 12 and acquires characteristic data of each cell 12 periodically. It has deterioration tendency judging means 14 for judging whether or not each cell 12 has a deterioration tendency based on the obtained characteristic data. Further, the battery monitoring life extension device 10 includes pulse pattern setting means 15 for setting the supply pattern of the pulse current to be supplied to the electrode (not shown) of each cell 12 based on the determination by the deterioration tendency determination means 14; A pulse current supply means 16 for supplying a pulse current to the electrode of each cell 12 according to each supply pattern set by the pulse pattern setting means 15 . Then, by supplying a pulse current more intensively than the electrodes of other cells 12 from the pulse current supply means 16 to the electrodes of the cells 12 determined to be deteriorating by the deterioration tendency determining means 14, Reduces sulfation (partially destroys (removes) the non-conductor film adhering to the electrode, or reduces the amount of non-conductor film adhering to the electrode (suppresses growth)) to slow down the progress of cell deterioration. It can be delayed and prolong life.

Here, when a pulse current is supplied to the electrode of each cell 12, the pulse current is normally supplied repeatedly at a predetermined cycle, and then, after an interval of rest, the pulse current is repeatedly supplied again at a predetermined cycle. Repeat pattern (pulse pattern). Therefore, the parameters of the pulse current supply pattern set by the pulse pattern setting means 15 are the period T ₁ when the pulse current is repeatedly supplied, the current value I of the pulse current, the pulse width T _W of the pulse current, the pulse current is repeatedly supplied at _a predetermined period T1, and there is a pause time _TS from when the pulse current is repeatedly supplied n _times at the predetermined period T1 to when the next pulse current supply is started. Then, in the intensive supply of the pulse current, for example, when supplying the pulse current to the electrode of the cell 12 determined to be deteriorating, the electrode of the other (normal) cell 12 is more a b) increasing the current value _I c) increasing the pulse width _TW d) increasing the number of repetitions n e) shortening the pause time _TS and f) combining any two or more of a) to e). Specifically, for example, in a normal state (for electrodes of a normal cell 12), once a month (regularly), a pulse current is supplied at a predetermined cycle only for five days, and deterioration For the electrode of the cell 12 determined to have a tendency to deteriorate, the electrode of the cell 12 is supplied with a pulse current at a predetermined cycle every day (continuously) until it is no longer determined to have a deterioration tendency by the repeated determination by the deterioration tendency determination means 14. A pulse current can be intensively supplied by supplying .
In this way, by setting the supply pattern of the pulse current supplied to the electrode of each cell 12 by the pulse pattern setting means 15 according to the state of each cell 12 (whether or not there is a deterioration tendency), necessary life extension measures can be applied.

The battery monitoring life-prolonging device 10 can also have a remote monitoring means 18 that obtains the characteristic data obtained by the characteristic data obtaining means 13 via the network line 17 and monitors the battery 11 from a remote location.

In particular, even if the batteries 11 are installed at a plurality of installation locations, they can be centrally managed (unifiedly managed) by one remote monitoring means 18 via the network line 17, reducing the cost required for patrol and maintenance. can. The network line 17 may be wired or wireless.
Furthermore, regardless of the determination by the deterioration tendency determination means 14, the administrator selects a specific cell 12 using the remote monitoring means 18, and applies the pulse current supply means to the electrode of the selected specific cell 12. A pulse current may be supplied intensively from 16 . In this case, the pulse pattern setting means 15 can be instructed from the remote monitoring means 18 to set the supply pattern of the pulse current supplied to the electrode of the specific cell 12 . As a result, life extension measures can be forcibly applied without relying only on the determination by the deterioration tendency determination means 14, and versatility is excellent. This compulsory life extension measure is, for example, when the administrator confirms the characteristic data acquired by the characteristic data acquisition means 13 and the judgment by the deterioration tendency judgment means 14 is wrong, there is no deterioration tendency, but there is no deterioration tendency. It is useful when the state close to continues.

Next, the details of the characteristic data acquisition means 13 will be described.

As a result, the deterioration tendency judging means 14 determines the deterioration tendency of the cell 12 whose internal resistance obtained by the internal resistance measuring means 20 is equal to or greater than a preset specified resistance value (for example, 1.5 times the reference resistance value). can be determined to be in
The battery monitoring life extension device 10 also has a cell replacement instructing means 23 for instructing replacement of the corresponding cell 12 when each cell 12 is nearing the end of its life. Then, the cell replacement instructing means 23 determines whether the cell 12 and the voltage measuring means 21 whose internal resistance obtained by the internal resistance measuring means 20 is equal to or higher than a preset upper limit resistance value (for example, twice the reference resistance value) It is possible to instruct the replacement of the cell 12 in which the obtained voltage has become equal to or lower than a preset lower limit voltage value (for example, 75% of the reference voltage value).
Further, the battery monitoring life-prolonging device 10 has a temperature abnormality notification means 24 that, when a temperature abnormality occurs in each cell 12, notifies the corresponding cell 12 of the abnormality and prompts inspection. Then, the temperature abnormality notification means 24 can notify the temperature abnormality of the cell 12 in which the temperature acquired by the temperature measurement means 22 is out of a preset specified temperature range (eg, 0 to 40° C.).

Here, the battery monitoring life-prolonging device 10 uses a conventionally known general-purpose computer equipped with a RAM, a CPU, a ROM, an I/O, and a bus (not shown) connecting these elements to can be suitably used as the control unit 25 that controls the . By using the computer as basic hardware and causing the CPU to execute a predetermined program, the computer functions as deterioration tendency determining means 14, pulse pattern setting means 15, cell replacement instructing means 23, and temperature abnormality reporting means 24. be able to. The predetermined program may be installed in the computer in advance, or may be stored in a storage medium such as a CD-ROM and read as appropriate and executed.
The cell exchange instructing means 23 and the temperature abnormality reporting means 24 display characters or symbols, blink, or change colors on a monitor (not shown) connected to the control section (computer) 25 and the remote monitoring means 18. and the like can be used to issue an instruction to replace the cell 12 and to notify of an abnormal temperature. In addition to or instead of the display on the monitor, a sound or warning sound may be emitted from a speaker, or a warning light may be lit or blinked. Furthermore, when a computer or a portable terminal having a mail reception function is used as the remote monitoring means 18, notification can also be made by mail.
The control unit 25 can store and totalize the characteristic data acquired by the characteristic data acquisition unit 13 and the supply pattern history of the pulse current supplied to each cell 12 . As a result, the user (administrator) of the battery monitoring life-prolonging device 10 can retrieve the data and confirm the process leading up to the occurrence of an abnormality in each cell 12 as necessary.
In the present embodiment, the computer functions as the deterioration tendency determination means 14, the pulse pattern setting means 15, the cell replacement instruction means 23, and the temperature abnormality notification means 24. The configuration is not particularly limited as long as it can perform the operation of , and each may be independent, or a part thereof may be integrated.

Next, a battery monitoring life extension method according to one embodiment of the present invention will be described based on the operation of the battery monitoring life extension device 10. FIG.
As shown in FIG. 3 , when the battery monitoring life-prolonging device 10 starts operating, first, a pulse current is periodically supplied to the electrodes of each cell 12 . The supply pattern of this pulse current is set by the pulse pattern setting means 15 shown in FIG. 1, and the pulse current is supplied from each pulse current supply means 16 to each cell 12 (periodic life extension step).
In parallel with this, the battery monitoring life-prolonging device 10 periodically acquires the characteristic data of each cell 12 that serves as a basis for determining deterioration of the battery 11 . Acquisition of this characteristic data is performed by the characteristic data acquisition means 13 shown in FIG. Specifically, the internal resistance, voltage, and temperature of each cell 12 are measured by the internal resistance measuring means 20, voltage measuring means 21, and temperature measuring means 22 shown in FIG. Note that the period for acquiring the characteristic data can be appropriately selected regardless of the period of supplying the pulse current to each cell 12 (this is the characteristic data acquisition step).

Then, the battery monitoring life-prolonging device 10 determines the next operation based on the characteristic data obtained in the characteristic data obtaining step. First, it is determined whether or not the voltage acquired by the voltage measuring means 21 is equal to or lower than a preset lower limit voltage value. Here, the cell 12 whose voltage has become equal to or lower than the lower limit voltage value is determined to be a voltage abnormal cell, and the cell exchange instructing means 23 instructs exchange (this is the voltage abnormal cell exchange instructing step).
For the cells 12 whose voltage is not equal to or lower than the lower voltage limit value, next, it is determined whether or not the temperature acquired in the characteristic data acquiring step is out of the preset specified temperature range. Here, the cell 12 whose temperature is outside the specified temperature range is determined to be a temperature abnormal cell, and the temperature abnormality notification means 24 notifies the temperature abnormality (this is the temperature abnormality notification step).
For the cells 12 whose temperature is not outside the specified temperature range, next, it is determined whether or not the internal resistance obtained in the characteristic data obtaining step is equal to or higher than a preset specified resistance value. Here, the cells 12 whose internal resistance is equal to or higher than the specified resistance value are determined to be deteriorating (deteriorating tendency cells), and the cells 12 whose internal resistance is not equal to or greater than the specified resistance value are determined to be normal cells. (The above is the deterioration tendency determination step).

Then, for the cell 12 determined to be deteriorating, it is further determined whether or not the internal resistance obtained in the characteristic data obtaining step is equal to or higher than a preset upper limit resistance value. Here, the cell 12 whose internal resistance is equal to or higher than the upper limit resistance value is judged to be a resistance abnormal cell, and the cell exchange instructing means 23 instructs to exchange the cell (this is the resistance abnormal cell exchange instructing step).
In addition, a pulse current is intensively supplied to the electrodes of the cells 12 whose internal resistance is equal to or higher than the specified resistance value and not equal to or higher than the upper limit resistance value. At this time, the pulse pattern setting means 15 shown in FIG. 1 instructs the pulse current supply means 16 connected to the relevant cell 12 to change the pulse current supply pattern, and A pulse current is supplied continuously (with a short cycle). The supply pattern of the pulse current can be selected as appropriate, but it is preferable to perform it continuously (or intermittently over a long period of time) until it is no longer determined that there is a deterioration tendency in the repeated deterioration tendency determination process. (The above is the intensive life extension process).
By periodically (periodically) repeating the above operation for each cell 12, the quality of the battery 11 can be stably maintained for a long period of time, and the power supply in an emergency can be reliably prepared.
As shown in FIG. 1, when the battery monitoring life-prolonging device 10 has the remote monitoring means 18, the specific cell 12 selected from among the plurality of cells 12 is It is also possible to carry out a compulsory life extension step in which a pulse current is intensively supplied to the electrodes.

Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations described in the above embodiments, and can be considered within the scope of the matters described in the claims. Other embodiments and modifications are also included.
For example, in the battery monitoring life extension method, it is possible to appropriately select the order and combination of judging the abnormal voltage cell, the abnormal temperature cell, the abnormal resistance cell, and the deterioration tendency cell.
In addition, when pulse current is intensively supplied (continuously in a short cycle) to the electrode of the cell, the pulse current with the same waveform may be repeatedly supplied, or the waveform (current value, pulse width, etc.) may be changed. Different pulse currents may be supplied sequentially. Furthermore, the periods when the pulse current is supplied intensively (continuously) do not have to be the same, and may be different. As the waveform of the pulse current, besides the rectangular wave, a raised cosine wave, a triangular wave, a sawtooth wave, and the like, and a combined waveform of these can also be applied.
In addition, the deterioration tendency determination process is performed regularly (periodically) in the same manner as the characteristic data acquisition process, but the period of the deterioration tendency determination process and the period of the characteristic data acquisition process do not necessarily match. , the cycle may be longer than the cycle of the characteristic data acquisition step.
