Description

BATTERY DISTILLED WATER FILLING SYSTEM

The present invention relates to a battery distilled water charging system, and more particularly, to a system for charging distilled water in an industrial battery.

In general, industrial batteries are used to supply electric power to various electric devices such as electric carts and electric forklifts as well as automobile batteries. These industrial batteries are basically used continuously while repeating discharge to generate power using a chemical reaction that occurs between the positive and negative plates and the electrolyte and charging to sulfide the electrolyte by electrical energy supplied from the outside.

For example, an electric forklift is driven by receiving power from a battery installed therein, and a fork is raised and lowered by operating a hydraulic system. Battery performance is directly related to forklift performance, so battery maintenance is important.

On the other hand, industrial batteries may cause deterioration in battery performance during charging and discharging. Specifically, as the charging and discharging processes of the battery are repeated, moisture evaporates due to a chemical reaction, thereby lowering the water level and increasing the concentration of the electrolyte, and the performance of the battery may be deteriorated. Accordingly, it is necessary to adjust the level and concentration of the electrolyte by supplementing distilled water.

1 shows an exemplary view exemplarily showing an overall schematic diagram of a battery distilled water charging system related to an embodiment of the present invention.

According to an embodiment of the present invention, the battery distilled water charging system 10 can determine whether distilled water is insufficient or satisfied by identifying or sensing the amount of distilled water related to the battery, and when it is determined that the distilled water is insufficient, the distilled water is added to the battery. Operations for replenishing or recharging may be performed.

The battery of the present invention may refer to a battery provided in an electric forklift. An electric forklift may refer to a work vehicle equipped with a mast that moves an engine, a traveling device, a hydraulic system, and a fork up and down, and effectively performs palletizing, loading on a truck, carrying or unloading work. . For example, the battery used in the electric forklift has a storage capacity of 48v-600AH, and may be a secondary battery including a lead storage battery, an alkaline storage battery, an MF storage battery, or a storage battery. For example, the battery may output a voltage of about 48 volts as each of the about 2 volt battery cells is connected in series with 24 cells. The specific description related to the above-described battery is only an example, and the present invention is not limited thereto.

These batteries may require additional supply or replenishment of distilled water in the course of continuous use. More specifically, the battery may be configured by using lead as a (-) pole and lead dioxide as a (+) pole, and using sulfuric acid having a specific gravity of about 1.25 as an electrolyte. In such a battery, as both electrodes become lead sulfate during discharging, the mass of both electrodes gradually increases, and the concentration of sulfuric acid, which is an electrolyte, gradually becomes thinner. When the concentration of sulfuric acid is continuously diluted, a material with high resistance is generated at the interface between the reactants, thereby shortening the life of the battery and making charging difficult. Accordingly, distilled water must be replenished before the battery is completely discharged. Batteries can undergo chemical reactions when they are charged and used. The sulfate of the positive plate is returned to lead oxide and sulfuric acid relatively easily when charged, whereas the sulfate of the negative plate may remain as it is without being returned to lead and sulfuric acid even after being charged. Therefore, in order to adjust the specific gravity of the electrolyte, distilled water must be periodically replenished.

In other words, as the charging or discharging process is repeated, water evaporates by a chemical reaction to lower the level of the electrolyte, and when the water level of the electrolyte decreases due to evaporation of water, the performance of the battery may deteriorate, so that Continuous supplementation may be required.

However, for this, the user must continuously visually check how much electrolyte is charged in the battery, and then go through the process of replenishing the battery, which may cause inconvenience to the user. In addition, when distilled water is supplied, if distilled water is oversupplied due to the user's carelessness, the electrolyte overflows to the outside, and the acidic component of the electrolyte may cause safety risks such as burns or corrosion of peripheral devices. There are concerns.

Accordingly, the battery distilled water charging system of the present invention, as shown in FIG. 1, may be provided with one or more valve devices 400 for controlling the replenishment or supply of distilled water in response to each of one or more batteries 300. . In this case, each valve device 400 may detect the water level in each battery 300 , and when it is determined that the water level has decreased to a certain level or more, it may allow supply of distilled water to each battery, and the water level may be constant If the above is satisfied, the supply of distilled water to each battery may be stopped. That is, one or more valve devices 400 are provided corresponding to each battery, and can control the replenishment of distilled water to each battery. Each of these valve devices 400 may be provided corresponding to each battery as it is fitted corresponding to the inlet formed on the upper surface of each battery.

For a specific example, as shown in FIG. 2 , a first inlet 301a may be formed on the upper surface of the first battery 301 among one or more batteries 300 , and the first inlet 301a may be Through the one or more valve devices 400, the first valve device may be fitted. The inlet provided on the upper surface of each battery may have a detachment mechanism for fixing and separating each valve device 400 . The desorption mechanism may include, for example, at least one of a clip desorption method, a magnetic desorption method, a band desorption method, or an adsorption desorption method, and the valve device 400 is easily fixed to the distilled water inlet through this desorption mechanism or can be separated. The detailed description of the above-described detachment mechanism is only an example, and the present invention is not limited thereto. That is, as the valve device 400 can be easily fixed and separated through a desorption mechanism formed in the distilled water inlet, stability when replenishing distilled water can be improved. For example, as the unintentional separation of the valve device is prevented in the process of replenishing distilled water, the occurrence of a hazardous situation such as exposure of the electrolyte composed of acid to the outside can be prevented.

As shown in FIG. 1 , the battery distilled water charging system 10 of the present invention may include one or more valve devices 400 provided corresponding to each of one or more batteries 300 that are connected in series. Each valve device 400 may receive distilled water from the storage unit 100 through the transfer pipe 200 , and may control the degree of supply or replenishment of distilled water into the battery according to the level of the battery.

Specifically, each valve device 400 may include a water level detection module, and may control the supply of distilled water to each battery according to the water level detection result of each battery 300 . Control related to the supply of distilled water may be individually performed for each valve device 400 . That is, it may be possible to individually supply distilled water to each battery according to the water level. A detailed method of supplying distilled water to each battery, a structural feature, and a description of a specific effect thereof will be described below with reference to FIGS. 3 to 7 .

The components included in the above-described system are exemplary, and the scope of the present invention is not limited to the above-described components. That is, additional components may be included or some of the above-described components may be omitted depending on implementation aspects of the embodiments of the present invention.

According to an embodiment of the present invention, the battery distilled water charging system 10 may include a storage unit 100 for storing (or storing) distilled water. That is, the storage unit 100 may serve to store distilled water to be supplemented in the battery. According to one embodiment, a part of the storage unit 100 may be provided with a pump for moving the distilled water. Distilled water stored in the storage unit 100 through such a pump may be supplied to each battery through the transfer pipe 200 . In an embodiment, the storage unit 100 is provided to be detachable from the system 10 so that it can be easily cleaned.

That is, since the transfer pipe 200 is provided to be replaceable in case leakage occurs due to aging, the stability of the system 10 can be improved.

According to an embodiment of the present invention, the distilled water charging system 10 may include one or more batteries 300 . The one or more batteries 300 may refer to industrial batteries for supplying power to the electric device. For example, the one or more batteries 300 may refer to each of 24 batteries connected in series to supply power to the electric forklift.

In one embodiment, each battery may be configured by using lead as a (-) pole, lead dioxide as a (+) pole, and sulfuric acid having a specific gravity of about 1.25 as an electrolyte. Each of these batteries may require periodic replenishment of distilled water to match the specific gravity of the electrolyte during charging and discharging to supply power.

In an embodiment, the one or more batteries 300 may be divided into one or more battery groups based on an arranged row or column. For example, one or more batteries arranged based on the same row may form a specific battery group. For example, as shown in FIG. 1 , six batteries located in the first row (ie, the first horizontal column) may form the first battery group 310 . In one embodiment, each battery group may allow the introduction of distilled water in response to different time points. For example, distilled water stored in the storage unit 100 may be supplied to each of the six batteries included in the first battery group in relation to the first time point, and in relation to the second time point different from the first time point, the second battery The distilled water stored in the storage unit 100 may be supplied to each of the six batteries included in the group. The above-described supply time and specific description related to each battery group are merely examples, and the present invention is not limited thereto.

One or more valve devices 400 are provided corresponding to each of the one or more batteries 300 , and may allow the inflow of distilled water into each of the one or more batteries 300 . A detailed description of the one or more valve devices 400 will be described below with reference to FIGS. 4 to 6 .

According to an embodiment of the present invention, the one or more valve devices 400, as shown in FIG. 4 , include a cover 410 , a driving member 420 , a channel forming member 430 and a housing 440 . can do. Components constituting the above-described valve device are exemplary, and additional components may be present, or some of the above-described components may be omitted.

The valve device 400 may include a cover 410 for protecting the components of the valve device. The cover 410 may be provided by forming a cylinder with an open lower surface. The open lower surface of the cover 410 may be coupled to the housing 440 . That is, the cover 410 places the components on the inside according to the coupling with the housing 440 , and can protect the internal components from external impact. An inlet groove 411 may be formed in a portion of the cover 410 . The inlet groove 411 may be provided through a shape corresponding to the shape of the inlet (ie, the portion connected to the transfer pipe) provided in the housing 440 . That is, as the inlet groove 411 is formed in a portion of the cover 410 , it can be coupled to the housing 440 without interference with the inlet 441 .

In one embodiment, the valve device 400 may include a lighting unit 500 to turn on the lighting related to one or more colors. The lighting unit may include, for example, an LED (Light Emission Diode), so that the state of the battery can be visually checked through the blinking of the LED. That is, the lighting unit 500 may be provided to visually easily recognize information related to a battery state (eg, battery failure, etc.) to a user through lighting of various colors. The lighting unit 500 may be provided on one surface of the cover 410 to provide visual information to the user. That is, when the valve device is coupled to the battery, the lighting unit 500 may be exposed on the upper surface of the valve device 400 , so that it is possible to provide visual information related to the battery state to the user. In one embodiment, the lighting unit 500 may be characterized in that it provides visual information to the user through various lighting methods in response to the sensing value of the specific gravity sensor module. Various lighting methods of the lighting unit 500 may be based on the control of the controller 700 . A detailed description of the control unit 700 for illuminating the lighting unit 500 in various lighting methods in response to the sensing value of the specific gravity sensor module will be described later.

The valve device 400 may include a driving member 420 for generating power by sensing a water level associated with each of one or more batteries. The driving member 420 may control the operation of the water channel forming member 430 by transmitting power to the water channel forming member 430 . For example, the water channel forming member 430 controls the amount of distilled water to be replenished with the battery by performing vertical motion through the power transmitted from the driving member 420 to open and close a channel through which distilled water can pass through the housing 440 . can do. The driving member 420 may be operated according to the water level detected by the water level detection module. In one embodiment, the driving member 420 may be a solenoid valve that applies a force to the water channel forming member 430 by generating an electromagnetic force of the electromagnetic coil based on a signal (frequency signal) related to the water level. . However, the driving member is not limited thereto, and may further include various power transmission components capable of supplying power to the water channel forming member.

The driving member 420 may include a water level detection module for detecting a water level related to each of one or more batteries. The water level detection module may include two lead wires 421 , and may sense the level of the battery through the corresponding lead wires. Specifically, the water level detection module may detect the water level through whether the tip of the lead wire is in contact with the electrolyte (ie, the electrolyte containing distilled water). The water level detection module may include a capacitor for outputting an electrical signal at a predetermined frequency. Two lead wires 421 may be connected to a portion of the capacitor, and in this case, only the end of the lead wire 421 may be exposed and the remaining portion may be covered. As shown in FIGS. 6 and 7 , the lead wire 421 is exposed to the outside through the upper through-hole 440a formed in the housing 440 , and then is inserted into the inner part of the battery through the insertion tube 442 . can be Specifically, the insertion tube 442 may be provided through the shape of the tube protruding so as to be inserted into the inner part of the battery. The insertion tube 442 may be provided with a through hole 442b through which a lead wire connected to a capacitor is inserted from the outside, and a lead wire may be inserted therein through the corresponding through hole 442b. Accordingly, when the insertion tube 442 is inserted into the inner part of the battery, the lead wire 421 passing through the inside of the insertion tube 442 may also be located inside the battery.

The lead wire 421 inserted into the inner part of the battery may be disposed at a predetermined height within the battery. In this case, the predetermined height may mean an appropriate height of the electrolyte in the battery. In other words, when the electrolyte is in contact with the lead wire 421 , since the level of the electrolyte in the battery is appropriate, replenishment of distilled water may not be necessary. Conversely, when the electrolyte does not contact the lead wire 421 , it may mean that distilled water needs to be replenished. The capacitor may transmit an electrical signal generated as the lead wire 421 comes into contact with the electrolyte to the level detection module, and the level detection module determines whether the electrolyte is at an appropriate level in the battery through a frequency corresponding to the electrical signal (ie, distilled water). whether supplementation is required) can be detected.

For example, if the electrolyte does not touch the end of the lead wire 421, the capacitor may output an electrical signal at a predetermined frequency (eg, 1600Hz), and the level of the electrolyte is not appropriate through the water level detection module. Depending on this, it can be detected that the replenishment of distilled water is necessary. For another example, if the end of the lead wire 421 is in contact with the electrolyte, due to the resistance of the electrolyte, the capacitor may output an electrical signal close to 0 Hz, and the water level detection module detects the appropriate level of the electrolyte in the battery through the output. can detect that The detailed description related to the output of the above-described capacitor is merely an example, and the present invention is not limited thereto.

In other words, the level detection module may detect whether the electrolyte is at an appropriate level in the battery based on the frequency of the electrical signal output from the capacitor. The driving member 420 may control an operation for replenishing the distilled water with the battery by transmitting power to the water channel forming member 430 based on a frequency related to the water level sensed through the water level detection module.

More specifically, as shown in FIG. 7 , the driving member 420 may be provided in contact with the water channel forming member 430 . The valve device 400 may include a water channel forming member 430 that determines whether to open or close the water channel through vertical movement. Specifically, the water channel forming member 430 may determine whether to open or close the water channel formed between the inlet 441 and the insertion tube 442 by performing a vertical motion based on the sensing value of the water level sensor module.

Specifically, as described above, the driving member 420 may sense the level of the electrolyte in the battery through the water level sensor module, and may apply a force to the water channel forming member 430 according to the detection result. The water channel forming member 430 is disposed in the upper direction of the housing 440 , and based on the control operation of the driving member 420 , opens and closes the water channel through up/down motion, thereby transferring the water from the storage unit 100 to the battery. It is possible to control the amount of distilled water to be supplied. That is, the water channel forming member 430 may be provided by being attached to the housing 440 in relation to the water channel forming space 431 , and opening the water channel through up/down motion according to the power transmitted from the driving member 420 . or it can be closed. In this case, the channel forming space 431 may be a space formed between the inlet 441 and the insertion tube 442 .

For example, when the driving member 420 senses that the electrolyte of the battery is insufficient and transmits power to the water channel forming member 430 , the water channel forming member 430 moves in a downward direction. Accordingly, the water channel forming space A canal can be opened on (431). Distilled water introduced through the inlet 441 may be replenished to the battery as it is discharged to the insertion tube 442 through the open water channel.

That is, as described above, the amount of distilled water supplemented to the battery may be controlled according to the operation of the driving member 420 and the water channel forming member 430 . For example, when the level of the electrolyte detected in response to the battery is low, the driving member 420 applies power to the water channel forming member 430 (that is, pressurizes) to open the water channel, so that the battery is replenished with distilled water. can In addition, when it is sensed that the level of the electrolyte detected in response to the battery is filled to a certain level, the driving member 420 stops the power transmission to the water channel forming member 430 to close the water channel, so that the distilled water in the battery is no longer may not be replenished. Accordingly, the replenishment of distilled water can be automated by the above-described mechanism, thereby improving user convenience.

According to an embodiment of the present invention, the valve device 400 may include a housing 440 in which an inlet 441 and an insertion tube 442 are formed. The inlet 441 may be connected to the transfer pipe 200 to allow supply of distilled water. That is, the inlet 441 and the storage unit 100 may be connected through the transfer pipe 200 , and the distilled water stored in the storage unit 100 may move to the battery through the inlet 441 . As shown in FIG. 5 , the inlet 441 may be formed to protrude outward. For example, the formation direction of the inlet may be a direction perpendicular to the direction in which distilled water is replenished to the battery.

The insertion tube 442 may be provided through a shape of a tube protruding so as to be insertable into a portion of the inner part of the battery. The insertion tube 442 may be inserted into an inner portion of the battery when the valve device 400 and the battery 300 are coupled. As the insertion tube 442 is provided inside the battery, the lead wire 421 connected to the driving member 420 is connected to the inside of the battery, or a passage for discharging distilled water flowing in through the inlet 441 to the battery. can play a role in shaping. The insertion tube 442 may be provided in a direction perpendicular to the direction in which the inlet 441 is provided, as shown in FIG. 5 . According to an embodiment, distilled water is introduced through the inlet 441 , passes through the water channel forming space 431 according to the operation of the driving member 420 , and is discharged to the battery through the insertion tube 442 .

According to an embodiment, the insertion tube 442 may include a through hole 442b through which a lead wire connected to the driving member 420 is inserted from the outside. The insertion tube 442 may be provided with a through hole 442b through which the lead wire 421 is inserted from the outside, and the lead wire 421 may be inserted into the insertion tube 442 through the corresponding through hole 442b. have. Accordingly, when the insertion tube 442 is inserted into the inner part of the battery, the lead wire passing through the inside of the insertion tube 442 may also be located inside the battery.

Also, the insertion tube 442 may include an outlet 442a provided through a predetermined diameter in order to discharge the distilled water introduced through the inlet 441 . That is, the distilled water introduced through the inlet 441 is discharged to the battery through the outlet 442a through the water channel forming space 431 according to the operation of the driving member 420 .

In the embodiment, the through-hole 442b and the outlet 442a formed in the insertion tube 442 may be characterized in that they are provided separately from each other. Specifically, as shown in FIG. 5 , the through hole 442b and the outlet 442a may be formed to face each other, and a blocking film may be formed between the through hole 442b and the outlet 442a. Accordingly, the through hole 442b and the outlet 442a may be provided to be partitioned from each other in the insertion tube 442 . This has the effect of improving the accuracy of water level detection by separately positioning the electric wire and distilled water in the insertion tube 442 . For example, when the lead wire 421 and distilled water are discharged in the same manner as the lead wire 421 in the insertion tube 442 , the water level may not be accurately detected by the water level sensor module as the distilled water comes into contact with the lead wire 421 . Therefore, by dividing the through hole 442b and the outlet 442a from each other to configure the insertion tube 442, the connection of the lead wire 421 related to sensing in one tube and the outlet related to the replenishment of distilled water can be simultaneously secured. have.

In summary, one or more valve devices 400 may be provided in correspondence with each of the one or more batteries 300 , and each valve device 400 may include one or more batteries 300 based on the water level measured in each battery 300 . ) to control the amount of distilled water replenished with each. For example, the first valve device may replenish 1L of distilled water by identifying that the electrolyte level in the first battery is relatively low, and the second valve device identifies that the electrolyte level in the second battery is relatively appropriate to supply distilled water may not be supplemented. That is, each valve device 400 may individually control the required amount of distilled water corresponding to each battery 300 . In other words, the amount of electrolyte in each battery is continuously checked through the water level, and the operation of replenishing distilled water in each battery based on the checked amount of electrolyte may be automated. Accordingly, the user's convenience is improved, and the stability problem generated in the distilled water replenishment process can be solved.

According to an embodiment of the present invention, the battery distilled water charging system 10 may include a sensor unit 600 . The sensor unit 600 may detect the amount of distilled water discharged from the storage unit 100 . For example, the sensor unit 600 may be related to a meter for measuring the discharge amount or discharge time of the distilled water stored in the storage unit 100 . The sensor unit 600 may be provided on one side of the transfer pipe 200 adjacent to the storage unit 100 . The discharge amount and discharge time of the distilled water sensed through the sensor unit 600 may provide meaningful information for determining whether or not the one or more batteries 300 are in a state.

According to an embodiment of the present invention, the battery distilled water charging system 10 may include a controller 700 that determines whether or not there is a failure related to one or more batteries based on a value sensed by the sensor unit 600 .

According to an embodiment, the control unit 700 may generally process the overall operation of the battery distilled water charging system 10 . According to an embodiment, the controller 700 may provide or process appropriate information or functions to a user (or an administrator) by processing input or output signals, data, information, etc. or by driving application programs stored in the memory. .

Specifically, the control unit 700 may determine whether the state of the one or more batteries 300 based on the information about the amount of distilled water discharged from the sensor unit 600 . For example, the control unit 700 may determine whether one or more batteries 300 have failed based on whether the amount of distilled water discharged from the storage unit 100 exceeds a predetermined threshold. As a specific example, based on the number of one or more batteries 300, a predetermined threshold related to the replenishment of distilled water may be set. For example, the threshold related to the replenishment of distilled water corresponding to 24 batteries may be determined to be 10L. That is, when 10L or more of distilled water is supplied (or supplemented) corresponding to a point in time, an abnormality may have occurred in at least one of the one or more batteries 300 .

The control unit 700 may obtain information on the amount of distilled water discharged in response to a specific time point through the sensor unit 600, and when the obtained amount of distilled water exceeds a predetermined threshold of 10L, one or more batteries 300 ), it can be determined that a failure has occurred in at least one of them. That is, when the replenishment amount of distilled water corresponding to a point in time deviates from a predetermined reference value, that is, when the replenishment of distilled water is made too much, the controller 700 may determine that the battery has failed. In one embodiment, when it is determined that a failure has occurred in the battery, the controller 700 controls the distilled water discharged from the storage unit 100 or transmits a failure-related notification signal to a terminal related to a user (eg, an administrator). can decide what

According to an additional embodiment, the introduction of distilled water into each of the one or more batteries may be performed for each one or more battery group units. Each of the one or more battery groups may be determined based on a row or column in which the one or more batteries are disposed. For example, one or more batteries arranged based on the same row may form a specific battery group. For example, as shown in FIG. 1 , six batteries located in the first row (ie, the first horizontal column) may form the first battery group 310 . In one embodiment, each battery group may allow the introduction of distilled water in response to different time points. For example, distilled water stored in the storage unit 100 may be supplied to each of the six batteries included in the first battery group in relation to the first time point, and in relation to the second time point different from the first time point, the second battery The distilled water stored in the storage unit 100 may be supplied to each of the six batteries included in the group. The above-described supply time and specific description related to each battery group are merely examples, and the present invention is not limited thereto.

According to an embodiment, each of the one or more valve devices 400 may include a supply amount detection sensor module for detecting the amount of distilled water supplied to each battery 300 . In this case, the supply amount detection sensor module may be characterized in that it identifies the supply amount and supply time of the distilled water based on the position of each channel forming member 430 corresponding to the valve device 400 .

More specifically, the water channel forming member 430 performs up and down movement through the power transmitted from the driving member 420 to open and close a channel through which the distilled water can pass in the housing 440 , thereby replenishing the amount of distilled water with the battery. can be controlled. For example, when the level of the electrolyte detected in response to the battery is low, the driving member 420 applies power to the water channel forming member 430 (that is, pressurizes) to open the water channel, so that the battery is replenished with distilled water. can In this case, the water channel forming member 430 may be positioned at the first position as it is pressed through the driving member 420 . Here, the first position may be related to the position of the water channel forming member 430 that allows the water channel to be opened on the water channel forming space 431 . In addition, when it is sensed that the level of the electrolyte detected in response to the battery is filled to a certain level, the driving member 420 stops the power transmission to the water channel forming member 430 to close the water channel, so that the distilled water in the battery is no longer may not be replenished. In this case, the water channel forming member 430 may be positioned at the second position as the pressure is released. Here, the second position may be related to the position of the water channel forming member 430 to close the water channel on the water channel forming space 431 . In other words, when the water channel forming member 430 is at the first position, distilled water may be replenished with the battery as the water channel is opened, and when the water channel forming member 430 is at the second position, the water channel is closed. Distilled water will not be replenished (or supplied) to the battery.

That is, the supply amount detection sensor module provided in each valve device 400 may identify the supply amount and supply time of the distilled water based on the first position of the water channel forming member 430 for supplying the distilled water to the battery. For example, the supply amount detection sensor module identifies the time when the water channel forming member 430 moves to the first position as the supply start time, and ends the supply when the water channel forming member 430 moves from the first position to the second position. time can be identified. Also, for example, the supply amount detection sensor module may identify the supply amount based on the supply start time and the supply end time. As a specific example, when the difference between the supply start time and the supply end time is 10 seconds, the supply amount detection sensor module may identify that 50 mL of distilled water has been supplied to the battery for 10 seconds. The specific numerical description related to the above-described supply amount monitoring sensor module is only an example, and the present invention is not limited thereto.

Also, in an embodiment, the controller 700 may differently determine a standard time for which distilled water is supplied to each battery based on a distance or location between the storage unit 100 and each battery. The standard time may mean a normal range with respect to the time point at which distilled water is supplied to each battery. That is, when the distilled water discharged from the storage unit 100 is supplied to each battery within a standard time, it relates to a normal operation, and when it is supplied after a standard time, it may be related to an abnormal operation (eg, malfunction).

For example, as the distances between the storage unit 100 and each battery are different, there may be a deviation in the time that distilled water is delivered to each battery. This is a phenomenon that occurs due to the friction of the supplied distilled water with the pipe. For example, when the distance between the storage unit 100 and the first battery is relatively close, distilled water discharged from the storage unit 100 may be supplied relatively quickly compared to other batteries. In this case, in the case of the second battery that is relatively far from the storage unit 100 , as distilled water is preferentially supplied to the first battery, the delivery of distilled water to the second battery may be relatively slow.

Accordingly, the controller 700 may differently determine the standard time for which distilled water is supplied to each battery based on the distance or location between the storage unit 100 and each battery. Specifically, in the above example, the control unit 700 may set the standard time to 2.5 to 3 seconds for the first battery to which the distilled water discharged from the storage unit 100 is preferentially supplied, and the standard time for the second battery The time can be set between 2.8 and 3.3 seconds. That is, the controller 700 may determine the standard time differently for each battery by considering that the supply amount of distilled water decreases due to friction in the transfer pipe as the battery is further away from the storage unit 100 .

On the other hand, the farther the battery is located from the storage unit 100, the more control is possible so that the valve provided in the battery is opened first for a predetermined time. There is an effect that can correct the difference in the amount of fluid supplied due to friction between the pipe and the fluid.

In an embodiment, the control unit 700 may determine whether or not a failure related to one or more batteries is based on a sensing value of each of one or more supply amount sensor modules corresponding to each battery group.

Specifically, each battery group may allow the introduction of distilled water in response to different time points. For example, distilled water stored in the storage unit 100 may be supplied to each of the six batteries included in the first battery group in relation to the first time point, and in relation to the second time point different from the first time point, the second battery The distilled water stored in the storage unit 100 may be supplied to each of the six batteries included in the group. That is, the distilled water discharged from the storage unit 100 at the first time point may be supplied to each battery corresponding to the first battery group, and the distilled water discharged from the storage unit 100 at the second time point is the second battery group. Each corresponding battery may be supplied. For example, if it is not appropriate for the amount of distilled water discharged at the first time point (eg, when distilled water is discharged above a predetermined reference value), the batteries included in the first battery group related to the first time point may be the cause of the failure. have.

The control unit 700 may identify the amount of distilled water supplied or supplemented to each battery corresponding to each battery group. Specifically, it is possible to identify the amount of distilled water supplemented in each battery through the supply amount detection sensor module provided in the valve device 400 of each battery. For example, the amount of distilled water supplemented in each of the six batteries may be identified through the supply amount detection sensor module corresponding to each of the six batteries corresponding to the first battery group.

The control unit 700 may determine whether there is a failure related to one or more batteries based on absolute comparison with respect to distilled water discharged to each battery. In this case, the absolute comparison may be characterized as a comparison between each amount of distilled water discharged to each battery and a predetermined reference amount. For example, the first battery group may include first to sixth batteries, and the amount of distilled water replenished corresponding to the six batteries may be identified through a supply amount detection sensor module corresponding to each battery. In this case, the control unit 700 may determine whether there is a battery-related failure by comparing each of the amounts of distilled water supplemented in correspondence with each of the six batteries with a predetermined threshold amount of distilled water. For example, if the predetermined critical distilled water amount that can be replenished to one battery at one time is 50 ml, the predetermined critical distilled water amount may be compared with the actual refilled distilled water amount with respect to each battery. As a specific example, the control unit 700 sets the amount of distilled water actually supplied to the first battery (ie, the amount of distilled water sensed through the supply amount detection sensor module corresponding to the first battery) to 60 ml, and 50 ml, which is a predetermined critical amount of distilled water. It can be determined that a failure has occurred in the first battery by identifying the excess. That is, when distilled water equal to or greater than a replenishable threshold value is supplied to each battery corresponding to a point in time, the controller 700 may determine that an abnormality has occurred in the battery.

In addition, the control unit 700 may determine whether each battery is faulty based on a relative comparison with respect to the amount of distilled water discharged from each of the one or more valve devices 400 corresponding to each battery group to each battery 300 . For example, the first battery group may include first to sixth batteries. When it is identified that a relatively large difference has occurred in the amount of distilled water supplied to a specific battery compared to other batteries based on the amount of distilled water supplied to each battery, the control unit 700 causes a failure in the battery included in the first battery group. can be determined to have occurred. As a specific example, when 3L, 3.1L, 3.12L, 2.98L, and 3L of distilled water were replenished in each of the first to fifth batteries for 30 days, but 7L of distilled water was replenished in the sixth battery, the control unit 700 is It may be determined that a failure has occurred in the sixth battery. The specific numerical description related to the distilled water supplemented to each battery described above is merely an example, and the present invention is not limited thereto.

That is, when the amount of distilled water supplemented to a specific battery among the six batteries included in the first battery group is significantly greater or less than that of other batteries, the controller may determine that a failure has occurred in the corresponding battery group.

In addition, the control unit 700 may determine whether each battery is faulty based on the supply time point at which distilled water is supplied to the battery from each of the one or more valve devices corresponding to each set. Specifically, the control unit 700 may identify points at which distilled water is replenished to each of the batteries corresponding to each battery group, and may determine whether the batteries have failed based on a deviation of the identified time points. As a specific example, the first to sixth batteries, that is, six batteries may be included in the first battery group, and by identifying when distilled water is replenished to each battery through each supply amount monitoring sensing module corresponding to each battery can be recorded In this case, when the controller 700 identifies that the replenishment time of distilled water for a specific battery is different from the replenishment time of distilled water of other batteries, the controller 700 may determine that a failure has occurred in the corresponding battery. For example, when it is identified that distilled water was replenished in the first to fifth batteries with respect to the first time point, but distilled water was replenished at a second time point different from the first time point in the sixth battery, the controller 700 controls the second time point. 6 It can be determined that the battery is faulty. That is, the controller 700 may identify time points at which distilled water is replenished to each battery, and when the deviation between the time points is large, it may be determined that a failure has occurred in the batteries having a time deviation from other batteries.

In one embodiment, when it is determined that a failure has occurred in the battery, the controller 700 controls the distilled water discharged from the storage unit 100 or transmits a failure-related notification signal to a terminal related to a user (eg, an administrator). can decide what That is, it is possible to provide notification information to the user by detecting an abnormality occurring in the battery. In addition, since the system of the present invention varies the supply amount at the time of supply of distilled water for each battery group, it is possible to obtain information on whether an abnormality has occurred in which battery group. That is, the user may be provided with more specific information related to battery failure, and accordingly, the convenience of continuous battery management may be provided.

8 is a flowchart exemplarily illustrating a process of replenishing distilled water of a battery and a process of determining whether a battery is faulty after replenishing distilled water according to an embodiment of the present invention.

According to one embodiment, each valve device 400 may be provided to correspond to each battery 300 . For example, a detachment mechanism for fixing and separating each valve device 400 may be formed at the inlet of each battery 300 . Each of the one or more valve devices 400 may be fixedly provided corresponding to each of the one or more batteries 300 through this detachment mechanism. In this case, each valve device 400 may supplement distilled water according to the electrolyte level of each battery.

Specifically, the water level detection module of each valve device 400 may detect the water level related to the electrolyte of the battery. The lead wire 421 connected to the water level sensing module may be inserted into the battery, and the water level may be detected depending on whether the electrolyte is in contact with the corresponding lead wire 421 . That is, when the electrolyte does not touch the lead wire 421, the capacitor can output an electrical signal at a predetermined frequency (eg, 1600 Hz), and the water level detection module determines that the level of the electrolyte is not appropriate through the output. can Accordingly, replenishment of distilled water to the battery may be initiated. The driving member 420 may cause the water channel forming member 430 to open the water channel by applying power to the water channel forming member 430 . For example, when the driving member 420 senses that the electrolyte of the battery is insufficient and transmits power to the water channel forming member 430 , the water channel forming member 430 moves in a downward direction. Accordingly, the water channel forming space A canal can be opened on (431). Accordingly, the distilled water introduced through the inlet 441 may be replenished to the battery as it is discharged to the insertion tube 442 through the open water channel.

As distilled water is continuously replenished, the electrolyte level of the battery may be increased, and may be in contact with the lead wire 421 for a moment. When the electrolyte touches the end of the lead wire 421, due to the resistance of the electrolyte, the capacitor may output an electrical signal close to 0 Hz, and the water level detection module detects that the electrolyte in the battery is at an appropriate level through the corresponding output. . Accordingly, the driving member 420 stops the power transmission to the water channel forming member 430 to close the water channel, so that the distilled water is no longer replenished in the battery. Replenishment of distilled water may be automated by the above-described mechanism, and thus user's convenience may be improved.

In one embodiment, when the replenishment of distilled water to the battery is completed, specific gravity measurement for the corresponding electrolyte may be performed. Specifically, each valve device 400 corresponding to each battery may include a specific gravity sensor module for measuring the specific gravity of the electrolyte included in each battery. The specific gravity of the electrolyte may be related to how much electricity is accumulated in the battery. According to an embodiment, the controller 700 may determine whether the performance of the battery is deteriorated by measuring the specific gravity of the electrolyte. Also, the controller 700 may control lighting of each lighting unit based on a sensing value measured through each specific gravity sensor module.

According to an embodiment, when the battery is completely discharged, the performance of the battery may be rapidly deteriorated. For example, when an electric forklift battery is discharged, sulfate is generated, and the generated sulfate may adhere to the electrode plate. If the sulfate adheres to the electrode plate, it may not come off easily even after charging. When sulfate is formed, the specific gravity of the battery electrolyte is lowered. In this case, the specific gravity of the electrolyte should be increased due to the sulfate falling off during charging, but as the sulfate adheres to the electrode plate, the specific gravity may not increase. Accordingly, the performance of the electric forklift battery may rapidly deteriorate.

That is, as described above, the performance of the battery may have a close relationship with the specific gravity of the electrolyte. Accordingly, the control unit 700 may determine whether the performance of each battery is degraded based on a sensing value measured through each specific gravity sensor module. For example, when the specific gravity of the electrolyte does not increase even during charging or the specific gravity of the electrolyte drops sharply to a certain value or more, the controller 700 may determine that the performance of the corresponding battery is degraded. Accordingly, the control unit 700 may provide visual information to the user by displaying on the lighting unit 500 corresponding to each battery in relation to the performance degradation of each battery determined through the electrolyte specific gravity of each battery. The lighting unit 500 may be provided on the upper surface of the valve device 400 corresponding to each battery 300 in order to visually easily recognize the information related to the battery state to the user through lighting of various colors.

For a specific example, the control unit 700 may light the lighting unit 500 in green when the specific gravity of the electrolyte is 1.28 or more, and when the specific gravity of the electrolyte is 0.8 or more and less than 1.28, the lighting unit 500 may be turned on in blue. And, when the specific gravity of the electrolyte is 0.6 or more and less than 0.8, the lighting unit 500 may be lit in yellow, and if the specific gravity of the electrolyte is less than 0.6, the lighting unit 500 may be lit in red. In this case, the green color may provide a visual perception effect indicating that the performance of the corresponding battery is excellent, and the red color may provide a visual perception effect indicating that the performance of the corresponding battery is severe. Descriptions related to specific numerical descriptions and colors in the above-described specific gravity of the electrolyte are merely examples, and the present invention is not limited thereto. As described above, the control unit 700 may determine the abnormal state of the battery according to the specific gravity of the electrolyte of each battery, and light the lighting unit 500 through various lighting methods based on the determined information. Accordingly, the user may be easily provided with information related to the battery state (eg, battery performance degradation) visually through lighting of various colors. In other words, even if the control unit 700 determines that the amount of distilled water supplied to each of the one or more batteries through the sensor unit 600 is appropriate, it is possible to determine whether performance degradation occurs in each battery based on the specific gravity of each battery. can

As a specific example, the control unit 700 may determine that an appropriate amount of distilled water (eg, 10L) has been discharged from the storage unit 100 at a first time in response to the first battery group through the sensor unit 600 . In this case, although the amount of distilled water discharged from the storage unit 100 included in the first battery group is appropriate, lighting of the lighting unit based on the specific gravity of each of the six batteries included in the first battery group may be different. For example, a green light may be turned on in the first to fifth batteries among the six batteries included in the first battery group, but a red light may be turned on in relation to the sixth battery. In this case, the controller 700 may determine that performance degradation has occurred with respect to the sixth battery even if an appropriate amount of distilled water is supplied to the corresponding first battery group.

That is, the control unit 700 does not only consider whether a failure occurs (or performance degradation occurs) through the overall supply amount or supply time of distilled water, but rather occurs in each battery based on the specific gravity of the electrolyte measured in response to each battery ( or performance degradation).

On the other hand, if all the lighting parts of the valve device connected to the battery group are turned on in green before a predetermined appropriate amount of distilled water is supplied to a specific battery group, the control unit blocks the supply of distilled water discharged from the storage unit or checks whether the user is blocked. signal can be transmitted.

Even if the batteries are all green, if an appropriate amount of distilled water is not supplied into the battery, the open state of the valve may be maintained until an appropriate amount of distilled water is supplied by the water level sensor.

The control unit 700 may continuously update information on an appropriate amount of distilled water for each group based on information on the total amount of distilled water supplied from the sensor unit 600 and information received from each valve device (electrolyte specific gravity, water level, etc.). The control unit 700 may also receive surrounding environment information through a separate temperature sensor and humidity sensor. Since the appropriate amount of distilled water supplied to each battery group is different depending on the season and the surrounding environment, the standard for the total amount of distilled water can be changed according to the environmental information obtained from the temperature and humidity sensors.
