Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The traditional intelligent charging and discharging mode through manual operation or remote control has the problems of long maintenance process time, low efficiency, low safety of a direct-current power supply system, high labor intensity of manpower, high labor cost increase and the like, and is gradually eliminated, so that storage battery maintenance products adopting technologies such as a strong current repair technology, a decomposition repair technology, a negative pulse repair technology, a high-frequency pulse repair technology, a positive sharp pulse resonance technology and the like are derived.
In the technical field of online intelligent maintenance of direct-current power supply storage batteries by adopting a physical method, an intelligent maintenance device for the storage batteries, which can really solve the problem of various practical application scenes of the direct-current power supply, does not exist. A device which really meets the requirements of users has two design conditions except that the working design of the device is reliable: the method adopts a lossless and efficient pulse-like resonance repairing technology and a perfect intelligent online work design depending on a practical application scene. Only the intelligent storage battery maintenance device which meets the two technical conditions can really and efficiently solve the defects of the storage battery in most practical application scenes. The existing device adopting the physical method technology has no design simultaneously with the two conditions, or because a lossless and efficient balanced resonant pulse repairing technology cannot be mastered, or because the actual application scene of the direct-current power supply storage battery is not completely understood, the intelligent design is incomplete, and the defect solving efficiency is low.
After the storage battery maintenance product adopting the prior art is analyzed, a plurality of problems still exist even if the product adopts an intelligent design, and the efficient online intelligent maintenance of the direct-current power supply storage battery cannot be really realized due to the limitations of low efficiency of the adopted storage battery repair technology, damage to the storage battery, scene requirements and other conditions, and finally the defects of the storage battery in the scene application cannot be fundamentally solved.
In addition, the service life of the direct-current power supply storage battery in different application scenes is different, the maintenance requirement on the storage battery is different, and the storage battery with different application scenes and different nominal capacities is provided with products with various models.
In view of the technical problem of low maintenance efficiency caused by narrow maintenance range of the battery maintenance device in the prior art, the invention provides a battery maintenance device, and the following describes specific embodiments and implementation modes of the battery maintenance device applied to the technical implementation of the invention with reference to the attached drawings.
Example one
Referring to fig. 1, a first embodiment of a battery maintenance apparatus of the present invention is presented.
The structural schematic diagram of the storage battery maintenance device shown in fig. 1 is connected with a storage battery, the storage battery comprises a plurality of battery packs connected in series, and the storage battery maintenance device comprises:
and a harmonic energy generation module 100 for generating the natural harmonic pulses.
The raw harmonic pulses are the unprocessed harmonic pulses generated by the harmonic energy generation module 100.
As shown in fig. 1, the harmonic energy generation module 100 is responsible for providing the original harmonic pulses and energy required by the device, is manufactured by a special process, is the core of the device, just like the heart of a human body, and the working efficiency directly affects the efficiency index of the whole device on the storage battery repair technology.
The harmonic balancing resonance module 200 comprises a plurality of harmonic resonance circuits, the harmonic resonance circuits are all connected with the harmonic energy generation module 100 and are connected with the battery packs in a one-to-one correspondence manner, and the harmonic resonance circuits are used for generating balancing harmonic pulses which resonate with sulfuric acid crystals according to the original ecological harmonic pulses, sending the balancing harmonic pulses to the battery packs and maintaining the battery packs.
The embodiment adopts an efficient balanced resonance pulse repairing technology, and the principle is that according to the principle that pulses with specific frequency have destructive effect on lead sulfate crystals generated by the storage battery, the existence and the growth of the lead sulfate crystals are interfered by using composite harmonic pulse energy to impact lead sulfate coarse grains, and the 'irreversible' vulcanized storage battery is changed into 'reversible'.
When the device with the balanced resonance pulse restoration technology works, pulse current with specific frequency and specific amplitude is continuously output to act on lead sulfate crystals with different sizes in the storage battery, so that the specific pulse frequency and the natural frequency of the lead sulfate crystals generate resonance, and when the energy is enough, the lead sulfate crystals are crushed and decomposed and dissolved in sulfuric acid electrolyte to participate in chemical reaction again.
The harmonic oscillation pulse repairing and maintaining technology is divided into a voltage harmonic oscillation pulse repairing technology and a current harmonic oscillation pulse repairing technology, wherein the current harmonic oscillation pulse repairing technology is also called as an equilibrium resonance pulse repairing technology, and is a comprehensive repairing and maintaining technology designed by combining a pulsating current and a harmonic resonance principle.
The balanced harmonic resonance module 200 is one of core modules for realizing high-efficiency repair and maintenance of the storage battery, and is also a key module for realizing low power consumption and low ripple voltage interference output.
In this embodiment, the storage battery maintenance device is connected to the storage battery, the storage battery is composed of a plurality of battery packs, the plurality of battery packs are connected in series, each battery pack is composed of one or more batteries, and if the plurality of battery packs are composed of a plurality of batteries, the plurality of batteries are connected in series to form one battery pack.
The balanced harmonic resonance module 200 is designed by adopting a plurality of working circuits, and is composed of a plurality of harmonic resonance circuits for managing a plurality of battery packs working in series on line, each harmonic resonance circuit is connected with the harmonic energy generation module 100, each harmonic resonance circuit is also connected with one battery pack, and each harmonic resonance circuit manages one battery pack.
According to the characteristics of series operation of the battery pack, by introducing a current concept design technology and matching with a high-efficiency active harmonic resonance technology, each single battery in the battery pack in series can obtain equal and enough harmonic resonance energy, so that the repair and maintenance rate of each single battery and the balance characteristic improvement rate of the battery pack can be more than 95% on the premise of not damaging a battery plate, the actual service life of the storage battery can be prolonged to the maximum extent, and the design life of the storage battery can be prolonged.
And a control module 300, connected to the harmonic resonance balancing module 200, for controlling the harmonic resonance circuits to sequentially operate according to a preset operation mode and/or a preset time sequence.
The control module is a brain for realizing intellectualization of the device, monitors the working state of the balanced harmonic resonance module 200 by converging, collecting and detecting the output signal of the balanced harmonic resonance module 200, reconfigures the working parameters of the device, realizes time sequence switching and adopts a multi-mode intelligent working mode.
The problem that average output power consumption of many existing similar products is large is always puzzled to users for a long time, and the problem is not in accordance with the policy of energy conservation and emission reduction advocated by the current country, for the battery pack of a plurality of series work of online management, the balanced harmonic resonance module 200 adopts a plurality of working circuit designs, and then the time sequence switching mode is introduced, so that the work output energy consumption can be greatly reduced, the output energy consumption is only dozens of watts, the ripple voltage interference can also be reduced, the ripple is smaller than 100mV, and therefore the maintenance efficiency of the device is improved.
Taking an application scenario in which the rated total voltage value of the storage battery is 110V as an example, if a plurality of circuits are not used, one circuit is used to manage a 110v =2v 54 storage battery with a nominal capacity of 100 to 500AH, the internal resistance of the 2V battery is 2m Ω in an extreme state, and the actual pulse unit grid amplitude is V = R × I = (2 m Ω × 54) = 5a = 054mv under the condition that the device outputs a pulse current of 5A, which is far higher than the requirement that the communication standard Vmax is less than or equal to 100 mV.
In the embodiment, the circuit for managing the storage battery is divided into multiple circuits, each circuit is connected with one battery pack in the storage battery, and then a time sequence switching mode design is introduced, when the device manages the 2v 54 storage battery, only one circuit works and outputs at a certain moment, and if the balanced harmonic resonance module consists of 9 harmonic resonance circuits, the voltage and the number of the batteries of the battery pack managed by one harmonic resonance circuit are 2v 6, at this moment, the voltage and the number of the batteries are calculated by taking 2m Ω in the extreme state of the internal resistance of the 2V batteries as the same, and under the condition that the device outputs pulse current 5A, the actual pulse unit grid amplitude is V = R I = (2 m Ω 6) = 5a =60mv, so that the requirement that the communication standard Vmax is not more than 100mV is met.
The control module 300 controls the plurality of harmonic resonance circuits to sequentially work according to a preset time sequence, specifically, if the 5 harmonic resonance circuits are numbered 1-5 in sequence, if the circuits are directly turned on from small to large in sequence, that is, the sequence of 1,2,3,4,5 or from large to small in sequence, there may be a situation that the switching between the last circuit and the first circuit is not timely, which causes the short circuit of the whole circuit, therefore, in actual implementation, the turn-on sequence may be set according to actual requirements, for example, the harmonic resonance circuit with the leading number of 1,3,5 is turned on, and then the harmonic resonance circuit with the number of 2,4 is turned on, so as to ensure the safety of the circuit working in the time sequence switching mode.
In different application scenarios, the service life of the dc power supply storage battery is different, the maintenance requirement for the storage battery is also different, and in practical application scenarios, a situation that the load of the dc power supply system varies may occur at any time, for example, the load is increased, the corresponding nominal capacity of the storage battery also changes, and if the nominal capacity range of the storage battery maintained by the original product that has been put into production is not wide enough, the maintenance efficiency of the original product that has been put into production is low.
In addition, the storage batteries of the conventional similar device are maintained and managed on line for a long time, the output power consumption is high, the device deeply understands the working characteristics of the storage batteries with different nominal capacities in different application scenes on the basis of adopting a balanced resonant pulse restoration technology with high restoration rate and lossless restoration, and introduces a multi-working mode design, thereby solving the problems.
According to the working characteristics of the storage battery in most application scenes, the storage battery generally does not exceed four weeks after a repair period, and then enters a low-power-consumption sleep standby mode, the storage battery is recovered to the optimal working state, the range of the reduction of the battery pack capacity caused by the occurrence of sulfation crystallization of the storage battery is still within an allowable range within 3-6 months later, specifically, the specific time of an interval period of 3-6 months is set according to the working discharge frequency condition of the battery pack in an actual application scene, so that the online working time of the device is reasonably set, the energy consumption is reduced, and the maintenance efficiency is improved.
In this embodiment, multiple working modes are introduced according to practical application situations, and the multiple working modes can be set as a first working mode, a second working mode, and a third working mode, which are as follows:
the first working mode is as follows: managing an online production storage battery with a nominal capacity range of 100 AH-500 AH, wherein the first working period of the terminal is 3 weeks, then the terminal works at intervals of 3-6 months, the working period is 2 weeks, and the working operation interval and the working period can be adjusted according to actual requirements;
and a second working mode: managing the on-line production storage battery with the nominal capacity range of 500AH to 1000AH, wherein the first working period of the terminal is 4 weeks, then the terminal works once every 3-6 months, the working period is 3 weeks, and the working operation interval and the working period can be adjusted according to actual requirements;
and a third working mode: the terminal working time is 7 × 24 hours, the working period is default to be unlimited, the time interval is 0, and the storage battery is started and stopped by manual intervention.
By adopting the balanced resonance pulse technology with high repair rate and no damage to the storage battery, the repair and maintenance efficiency can maximally reach more than 95% on the premise of not damaging the battery plate, so that the actual service life of the storage battery can maximally reach the design life of the storage battery. In addition, the added time sequence switching mode and the comprehensive design of multiple working modes by matching with software are realized, the output power consumption and ripple voltage interference of the storage battery maintenance device are reduced, the lossless and efficient online intelligent maintenance of the storage battery is realized, the nominal capacity range of the storage battery managed by one type of product is wider, the storage battery is basically suitable for managing the direct-current power supply storage battery of most fixed application scenes, the maintenance range of the storage battery maintenance device is expanded, and the intelligent maintenance efficiency is ensured.
Example two
Referring to fig. 2, a second embodiment of the battery maintenance apparatus according to the present invention is provided on the basis of the first embodiment.
Further, as shown in the schematic structural diagram of the battery maintenance apparatus shown in fig. 2, the battery maintenance apparatus may further include:
and the pulse voltage suppression module 400 is connected with the storage battery and used for monitoring the total voltage value of the storage battery and outputting the total voltage value.
As shown in fig. 2, the storage battery includes a plurality of battery packs, the pulse voltage suppression module 400 is respectively connected to the first battery positive electrode of the first battery pack and the last battery negative electrode of the last battery pack, and if the storage battery includes 9 battery packs, numbered 1 to 9, the pulse voltage suppression module 400 is respectively connected to the first battery positive electrode of the battery pack numbered 1 and the last battery negative electrode of the battery pack numbered 9.
The control module 300 is connected to the pulse voltage suppression module 400, and is further configured to control the pulse voltage suppression module 400 to slightly discharge the battery when the total voltage value is greater than or equal to a first preset voltage value, and control the pulse voltage suppression module to stop slightly discharging the battery pack when the total voltage value is less than or equal to a second preset voltage value, wherein the first preset voltage value and the second preset voltage value are both greater than a rated total voltage value of the battery, and the first preset voltage value is greater than the second preset voltage value.
The pulse voltage suppression module 400 in the battery maintenance device can solve the problems that the battery loses water and finally swells, the battery is out of service and the total voltage of the battery of the Power Supply System is mistaken for alarm due to pulse resonance technology, including forward sharp pulse repair technology and the existing equilibrium resonance pulse repair technology, in different direct current Power Supply application scenes such as UPS (uninterruptible Power Supply), EPS (Emergency Power Supply), a starting Power Supply, a direct current screen Power Supply, a switching Power Supply and an energy storage Power Supply.
The water loss of the battery is basically caused by water electrolysis in the charging process, the main reason is that the constant voltage value of charging, the float current converted by the constant voltage and the float voltage are different, so the gassing amount and the charging capacity are different, and in order to overcome the water loss in the float charging stage, the float charging monomer voltage of the battery is usually set to be 2.25V-4mV.
Because the accumulated voltage is too high when the pulse resonance type repairing technology acts on the storage battery for a long time on line, after the voltage of the single battery in the storage battery is accumulated to 2.35V, a positive plate of the storage battery starts to generate a large amount of oxygen, if an oxygen circulation channel is not played, the oxygen directly reaches a negative plate to be synthesized into water, and when the amount of the generated oxygen is too large, the oxygen is discharged through an exhaust valve of the storage battery. When the voltage of the single battery is accumulated to 2.42V, the negative plate begins to evolve hydrogen, a hydrogen circulation channel does not exist in the battery, and the evolved hydrogen and oxygen are exhausted. The discharged oxygen and hydrogen cannot be reduced to water, so that exhaust gas and water loss are formed, and the probability of offline scrapping of the battery due to bulging is increased along with the aggravation of water loss of the single battery.
In this embodiment, taking an application scenario in which the rated total voltage value of the storage battery is 110V as an example, the first preset voltage value is 126.9v =2.35v 6 x 9, and the second preset voltage value is 121.5v =2.25v 6 x 9.
The storage battery is divided into 9 battery packs connected in series, and each battery pack is formed by connecting 6 batteries with the voltage of 2V in series. The pulse voltage suppression module 400 is connected to both ends of the storage battery, monitors the total voltage value of the storage battery in real time, and transmits the monitored total voltage value to the control module 300.
The control module 300 compares the total voltage value with the first preset voltage value 126.9V, and if the total voltage value is greater than or equal to 126.9V, the control module 300 controls the pulse voltage suppression module 400 to perform micro-discharge on the battery to reduce the total voltage value of the battery until the total voltage value is reduced to 121.5V.
In the micro-discharging process, the control module 300 compares the total voltage value monitored by the pulse voltage suppression module 400 with a second preset voltage value of 121.5V, and if the total voltage value is less than or equal to 121.5V, the control module 300 controls the pulse voltage suppression module 400 to stop micro-discharging the storage battery so as to keep the total voltage value of the storage battery in a relative safety range, thereby avoiding the problems that the storage battery is finally swelled and scrapped due to water loss and the total voltage of the storage battery of the power supply system is mistakenly alarmed because the accumulated total voltage value of the battery pack exceeds 130.68v =2.42v × 6 for a long time.
Aiming at the problems that the existing storage battery maintenance device adopts a single pulse resonance technology in some special fixed application scenes such as UPS/EPS/starting power supply and the like, the storage battery is finally swelled due to water loss and the off-line is scrapped due to overhigh accumulated voltage when the pulse resonance technology acts on the storage battery for a long time on line, and the total voltage of the storage battery of a power supply system is falsely alarmed.
In the embodiment, by adopting a design combining an equilibrium resonance pulse technology and a pulse voltage suppression technology, the pulse voltage suppression module 400 monitors the total voltage value of the storage battery in real time, and the control module controls the pulse voltage suppression module to start/stop micro-discharging on the storage battery according to the total voltage value of the storage battery so as to control the total voltage value of the storage battery to be kept in a preset range, thereby solving the problem that the pulse resonance technology is singly adopted in part of special fixed application scenes such as UPS/EPS/starting power supply, and the storage battery maintenance device product of the embodiment is suitable for more DC power supply application scenes.

In this embodiment, the battery maintenance apparatus may include:
the harmonic wave energy generation module 100, the balanced harmonic wave resonance module 200, the control module 300, the pulse voltage suppression module 400, the power supply protection module 500 and the protection module 600. The balanced harmonic resonance module 200 may include a plurality of harmonic resonance circuits.
Further, the balanced harmonic resonance module 200 may further include:
the clock generating unit is connected with the harmonic resonance circuit and used for providing a reference frequency;
the pulse counting unit is connected with the harmonic resonance circuit and is used for providing a time sequence frequency;
and the harmonic resonance circuit is also used for superposing the reference frequency and the original ecological harmonic pulse based on the time sequence frequency to generate a balanced harmonic pulse.
In this embodiment, the harmonic resonance module 200 further includes a pulse counting unit, which provides a timing frequency, so that the harmonic resonance circuit can work based on the timing frequency.
The balanced harmonic resonance module 200 further comprises a clock generation unit that provides a reference frequency of 8.33khz, which is also the optimum frequency for resonance with the battery sulfuric acid crystals.

When the output short-circuit protection circuit detects that the output short-circuit phenomenon occurs to any one of the harmonic resonance circuit and the battery pack, the safety device connected with the harmonic resonance circuit and the battery pack loop is firstly fused, and then the fault protection process is executed.
And the working abnormity protection circuit is used for detecting whether the harmonic resonance circuit has a working abnormity fault or not, and correspondingly outputting a third abnormal detection signal if the harmonic resonance circuit has the working abnormity fault.
