Description

Technical Field

[0001] The present invention relates to the technical field of battery repair, and in particular to a battery repair fluid and a repair and filling device thereof. Background Art

[0002] With the development of new energy at this stage, more and more power equipment has begun to use electricity for power supply. Batteries are a commonly used energy storage device in power systems. Lead-acid batteries have advantages such as simple system structure, mature technology, and low manufacturing cost.

[0003] At present, the failure of lead-acid batteries is mainly due to reversible damage (such as sulfation, water loss, etc.) rather than complete scrapping. According to statistics, of the 200 million lead-acid batteries eliminated each year, at least 50 million can be repaired and regenerated, which can reduce resource waste and environmental pollution. The repair cost is usually only 30%-50% of that of a new battery, significantly reducing the replacement cost for users.

[0004] Furthermore, in order to increase the service life of lead-acid batteries and reduce resource and environmental pollution, repairing the batteries is a relatively economical and environmentally friendly form. At present, the types of damage to lead-acid batteries mainly include the formation of a dense lead sulfate layer on the surface of the plate, which leads to increased internal resistance, decreased capacity, and electrolyte evaporation leading to exposure of the plate and shedding of active substances. Therefore, most repair fluids for lead-acid batteries require special proportioning after diagnosis. The maintenance cycle is long during use, so there is a problem of inconvenient operation. Moreover, the repair fluid is mostly injected manually, which is cumbersome and inconvenient to control and observe the injection amount.

[0005] In response to the above problems, there is currently a lead-acid battery repair liquid and a method for repairing lead-acid batteries using the same disclosed in publication number CN103474707B. The liquid is connected in series with the battery to achieve component replenishment. However, this method requires complex equipment and is inconvenient to carry and operate. At the same time, it is only limited to the repair of negative electrode active materials, and cannot meet other types of repair needs. In view of this, in-depth research on the above problems has led to the emergence of this case. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-9The present invention provides an implementation scheme: In modern new energy equipment, many devices rely on lead-acid batteries for power supply. During the application process, lead-acid batteries will be damaged due to long-term use due to the formation of a dense lead sulfate layer on the surface of the plate, resulting in increased internal resistance, decreased capacity, and electrolyte evaporation leading to exposure of the plate, and shedding of active substances. In order to repair this damage, the battery needs to be repaired. However, the current repair methods, such as a lead-acid battery repair liquid and a method for repairing a lead-acid battery using the same as described in a public patent, achieve component replenishment by connecting it in series with the battery. However, this method requires complex equipment and is not easy to carry and operate. It is also limited to the repair of negative electrode active substances, and cannot meet other types of repair needs. At the same time, the repair liquid is mostly manually extracted for injection, which is cumbersome and inconvenient to control and observe the injection amount.

[0032] Example 1: To address the above issues, the present application discloses a battery repair fluid that can be used in different proportions for different repair types. Specifically, it is mainly divided into two repair fluid forms, and the two repair fluids can also be mixed. Deionized water is required in the proportions of the two repair fluids, so the deionized water uses independent storage and metering equipment; The formula of the sulfide repair fluid is applicable to scenarios where the lead-acid battery is undercharged or over-discharged for a long time, resulting in the formation of dense lead sulfate crystals and sulfide on the plate surface, which manifests as a decrease in capacity and an increase in internal resistance. The detailed ratio is shown in Table 1. Table 1 Vulcanization repair fluid formula Function and effect: Desulfurization core: EDTA-2Na decomposes PbSO4 through complex reaction, restoring the electrochemical activity of the plate active material (PbO2 / Pb).

[0033] Double protection: Sodium sulfate replenishes the electrolyte ion concentration, and sodium humate protects the plates, reducing the risk of subsequent sulfidation.

[0034] Rapid penetration: PEG-400 improves the penetration efficiency of the repair solution into the micropores of the plate, shortening the repair time (30% shorter than traditional methods).

[0035] Verification results: After repairing a 12V / 100Ah battery with capacity attenuation caused by sulfation (60% of the original capacity), the capacity recovered to 85%-90% and the internal resistance decreased by 35%-45%.

[0036] Applicable scenarios for the electrolyte regeneration and repair liquid formula: When the battery is exposed to electrolyte evaporation and the plates are exposed and the active material falls off due to high temperature or overcharging, the specific manifestations are liquid level drop and plate deformation. The specific ratio is shown in Table 2.

[0037] Table 2 Electrolyte regeneration repair solution formula Function and effect: Electrolyte reconstitution: Accurately replenish sulfuric acid concentration to restore the chemical balance of the electrolyte.

[0038] Active material fixation: Fumed silica forms a three-dimensional network structure, capturing detached substances and adhering them to the surface of the plate.

[0039] Long-term stability: Ammonium dihydrogen phosphate inhibits electrolyte oxidation, and sodium lignin sulfonate enhances dispersibility, extending the cycle life of the repaired battery by 20%-30%.

[0040] Verification results: After repairing a 6V / 200Ah traction battery with electrolyte evaporation exceeding 30%, the liquid level returned to the standard value, the capacity increased to 92%-95%, and the plate shedding rate decreased by 80%.

[0041] Example 2: In order to enable rapid repair of lead-acid batteries, the present application also discloses a battery repair fluid repair and filling device, which is used for operations such as liquid injection, pulse activation, and proportioning in lead-acid battery repair. Specifically, it includes a mobile base 1, on which is provided a repair storage tank 2, in which the above-mentioned repair fluid is stored. The number of the repair storage tanks 2 is plural, and the solenoid valves are controlled by the control center to achieve rapid combination switching. Repair tanks with different functions can be automatically matched and called according to the battery degradation characteristics. A water storage tank 3 is provided on the mobile base 1, and the water storage tank 3 stores deionized water and is connected to the mixer 7 to ensure the ultra-pure properties of the dilution water in real time; According to the instruction manual Figure 1 -Attached Figure 3 It can be seen that the mobile base 1 is provided with a filling exchanger, which is connected to the repair tank 2 through a mixer 7. The mixer 7 accurately grabs the raw materials of different tanks through multiple channels, forms a vortex fusion under the control of the fluid mechanics algorithm, and mixes the materials of the repair tank 2. During mixing, high-frequency shearing and low-speed kneading are alternately generated, so that the active ingredients of the repair liquid are evenly distributed at the molecular level. After mixing, the liquid is filled into the lead-acid battery through the filling exchanger. According to the instruction manual Figure 1 -Attached Figure 3It can be seen that the above-mentioned filling exchanger also includes a buffer cylinder 4, which is connected to the mixer 7. The internal pressure field of the buffer cylinder 4 forms a dynamic balance with the output pulsation of the mixer 7 to ensure continuous and stable transmission of the mixed liquid. The buffer cylinder 4 is equipped with a linear controller 5. The end of the buffer cylinder 4 is connected to the filling pipe 41, and the end of the filling pipe 41 is connected to the liquid exchange joint 42. The liquid exchange joint 42 is made of rubber material and can automatically adjust the sealing contact pressure according to the deformation of the battery filling port. The mobile base 1 is provided with a linear controller 5, which is connected to the control piston 54 in the buffer cylinder 4. The two are controlled by the encoder to achieve millimeter-level spatial trajectory synchronization to ensure accurate injection and uniform pressure. According to the instruction manual Figure 1 -Attached Figure 3 It can be seen that the above-mentioned filling exchanger also includes a pulse activation device 6, which is composed of a main control module, a pulse generator, a current and voltage regulation module, and a protection and detection module. Its energy release rhythm forms a precise timing coupling with the filling flow rate, and stimulates a directional ionization effect at the moment when the repair liquid infiltrates the plate. A pair of leads 61 are provided on the pulse activation device 6, and the pair of leads 61 are respectively connected to the positive and negative poles of the battery. The intelligent clamping mechanism cleans the electrode surface while power is applied, eliminating the interference of contact impedance on the activation effect; According to the instruction manual Figure 1 -Attached Figure 4 It can be seen that the mixer 7 includes a mixing barrel 71, which is connected to the buffer barrel 4 and the repair tank 2. The mixing components therein can perform shear stirring to avoid stratified mixing effects and prevent precipitation of active substances. The mixing barrel 71 is provided with a mixing component, which mixes the materials in the mixing barrel 71. The combined stirring blades form a three-dimensional cross-mixing effect, which greatly improves the dispersion efficiency of the repair agent. According to the instruction manual Figure 1 -Attached Figure 5 As can be seen, the mobile base 1 is equipped with a placement seat 11 for placing lead-acid batteries. Its multi-dimensional sensor array automatically identifies the battery's posture, providing a spatial positioning reference for the robotic arm. The placement seat 11 is also equipped with an ultrasonic oscillator 8. When the repair fluid is injected, it automatically excites the resonant wave field, causing the liquid to form an osmotic wave conduction along the gaps between the plates, generating an energy superposition effect with the pulse activation. According to the instruction manual Figure 1 -Attached Figure 5It can be seen that the mobile base 1 is a rectangular plate. A support base 12 is provided on one side of the mobile base 1. The support base 12 is connected to the repair tank 2 to ensure the dual-state stability of movement and operation. Two pairs of mobile rollers 13 are provided on the bottom surface of the mobile base 1. Its intelligent power-assisted drive and manual push handle 14 form human-machine collaborative control, which can achieve positioning accuracy comparable to that of precision instruments in narrow spaces. A push handle 14 is provided on one side of the mobile base 1, and a control panel 15 is also provided on the mobile base 1. The entire machine is powered by the control panel 15 connected to an external power supply. The human-machine interaction interface of the control panel 15 is deeply interconnected with the core components of the equipment. According to the instruction manual Figure 1 -Attached Figure 6 It can be seen that the repair tank 2 is a hollow tank with a cylindrical structure. The repair tank 2 is provided with a feeding controller 21, which forms a millisecond-level response with the demand signal of the mixer 7. The bottom of the repair tank 2 is provided with a liquid outlet 22. One side of the liquid outlet 22 is connected to the mixing cylinder 71 through a liquid outlet pipe. The liquid outlet pipe is provided with a control valve 23. The opening and closing action of the valve is precisely coordinated with the suction of the mixing cylinder 71 to achieve pulse-free continuous liquid supply. Specifically, the feeding controller 21 includes a feeding control seat 211, which is mounted on the repair tank 2. A feeding control motor 215 is mounted on the feeding control seat 211. A feeding control sleeve 212 is connected to the driving end of the feeding control motor 215. A telescopic screw 213 is internally threadedly connected to the control sleeve. The end of the telescopic screw 213 is connected to a feeding piston 214. The feeding control motor 215 converts rotational motion into linear displacement of the telescopic screw 213, so that the telescopic screw 213 pushes the feeding piston 214 to move, ensuring smooth output of the viscous repair fluid. The intelligent lubricating layer on the piston surface automatically adjusts the friction coefficient as the pressure changes, achieving initial accuracy after millions of operations. Furthermore, the buffer cylinder 4 is a hollow cylinder with a cylindrical structure. A mounting seat is provided at the bottom of the buffer cylinder 4 and is connected to the mobile base 1. The buffer cylinder 4 is connected to the mixing cylinder 71 and the filling pipe 41 respectively. The mixing cylinder 71 and the filling pipe 41 are built with valve check valves. The buffer cylinder 4 extracts the repair fluid from the mixing cylinder 71 in one direction and then pushes it into the battery through the filling pipe 41 through a one-way action. In order to maintain the optimal working state of the active material, a heat preservation and constant temperature structure can be provided on the buffer cylinder 4 to keep the active material at a suitable working temperature. According to the instruction manual Figure 1 -Attached Figure 7As can be seen, the linear controller 5 includes a reciprocating control motor 51 mounted on the mobile base 1. A control screw 52 is connected to the drive end of the reciprocating control motor 51. Its preloaded transmission pair and displacement feedback system form an ultra-precise motion closed loop, converting subtle electrical signals into precise fluid control. A propulsion block 53 is threaded onto the control screw 52, which is connected to a propulsion rod. The end of the propulsion rod is connected to a control piston 54. A dual-redundant sensing system compares the piston's posture in real time, eliminating the accumulated errors caused by mechanical backlash through a dynamic compensation algorithm. According to the instruction manual Figure 1 -Attached Figure 9 As can be seen, the ends of the pair of leads 61 are respectively connected to a pair of connectors 62. A pair of quick-release conductors 63 are provided on the connectors 62. The contact pressure of the quick-release conductors 63 can be flexibly varied to ensure a secure release from the positive and negative electrodes of the battery, ensuring lossless energy conduction under different operating conditions. Specifically, the quick-release conductors 63 consist of a conductive sleeve 631 assembled within the connector 62 and a pair of elastic clips 632 located on either side of the conductive sleeve 631. The outer cover of the quick-release conductors is made of insulating rubber material to ensure a secure grip. According to the instruction manual Figure 1 -Attached Figure 4 It can be seen that the above-mentioned mixing assembly includes a mixing motor 72, which is installed on the mobile base 1. The driving end of the mixing motor 72 is connected to a gear speed regulator 73. Its multi-mode driving strategy is deeply bound to the material characteristics, realizing a stepless transition from gentle stirring to intense dispersion. The output end of the gear speed regulator 73 is connected to a mixing shaft 74, which extends into the mixing barrel 71. A plurality of mixing blades 75 are arranged in a linear array on the mixing shaft 74. The fluid force field generated by the bionic paddle shape perfectly matches the barrel diversion structure, forming a continuously self-optimizing mixing environment. According to the instruction manual Figure 1 -Attached Figure 8 It can be seen that the above-mentioned ultrasonic oscillation device 8 includes at least one pair of fixing seats 81. At least one pair of fixing seats 81 is arranged on both sides of the placement seat 11. An ultrasonic transducer 82 is arranged on the fixing seat 81. Its frequency forms an acoustic resonance with the internal structure of the battery, so that the repair fluid produces a micro-impact penetration effect. A vibration transmission seat 83 is arranged on the fixing seat 81. The vibration transmission seat 83 is in contact with the battery. The adaptive coupling agent automatically fills the tiny gap at the moment of contact to construct a complete vibration energy transmission channel.

[0042] Example 3: The core process of the equipment working method includes an intelligent diagnosis stage, a collaborative operation stage, and a closed-loop maintenance stage; Intelligent diagnosis stage: The battery scanning module identifies the battery type (lead-acid / colloid / AGM) and failure mode (sulfation / dehydration / plate shedding). The built-in database matches the repair solution and automatically selects the sulfide supplement or electrolyte supplement repair mode. In the dynamic liquid distribution stage, the repair tank intelligently calls the corresponding raw materials: Sulfide Repair: Activating Tanks with Chelating Agents / Corrosion Inhibitors Electrolytic repair: call high-purity sulfuric acid / fumed silica storage tank The mixer executes a precise ratio algorithm with an error rate of <0.5% Collaborative operation stage: The filling pipe adaptively seals the filling port, pulse activation and ultrasonic oscillation are started synchronously, the system automatically adjusts according to the type of repair fluid, high-frequency pulses (8-10kHz) break crystals, and gradient pressure injection (0.3-0.6MPa) fills the gap between the plates; Closed-loop maintenance phase: Real-time monitoring of battery internal resistance and voltage change curves, automatic generation of repair reports, and recommendation of secondary repair cycles.
