Abstract
Description
Technical Field
[0001] This invention belongs to the field of battery repair, and specifically relates to equipment and methods for charging, discharging, maintaining and repairing lead-acid batteries. Background Technology
[0002] Lead-acid batteries are relatively inexpensive compared to other types of batteries due to their manufacturing process, and they are still used in some equipment. However, with prolonged use and frequent charging, the sulfuric acid inside the lead-acid battery and the electrodes undergo sulfation, which reduces the battery's lifespan. Furthermore, lead-acid batteries are highly polluting. Therefore, extending the lifespan of lead-acid batteries reduces the number of discarded batteries, saving money, reducing environmental pollution, and decreasing the frequency of battery replacements, thus significantly improving work efficiency.
[0003] Therefore, we propose equipment for the charging, discharging, maintenance, and repair of lead-acid batteries, along with its usage methods. Summary of the Invention
[0004] The purpose of this invention is to provide a lead-acid battery charging, discharging, maintenance and repair device and its usage method to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a lead-acid battery charging and discharging maintenance device, comprising a frame, an integrated charging, discharging and repair module, a display screen, a high-frequency switching power supply, and an industrial-grade touch screen all-in-one machine, characterized in that: the interior of the frame is divided by partitions, the industrial-grade touch screen all-in-one machine is located at the bottom of the frame, the integrated charging, discharging and repair module is placed on the upper surface of the partitions inside the frame, the side wall of the frame is hinged with a door, the display screen and the high-frequency switching power supply are both embedded in the door, and the display screen and the high-frequency switching power supply are electrically connected to the integrated charging, discharging and repair module.
[0006] Preferably, a heater is provided in the rack below the battery storage compartment.
[0007] The equipment and methods for maintaining and repairing lead-acid batteries by charging and discharging include the following steps:
[0008] S1. After the battery to be charged is connected to the electrode post in the battery storage compartment, the constant current charging stage begins.
[0009] S2. When the voltage of the constant current charging stage reaches the set voltage, the constant voltage current limiting charging stage begins.
[0010] S3. When the current in the constant voltage and current limiting stage gradually decreases to the set value, the noise pulse charging stage begins.
[0011] S4. Once the current during the noise pulse phase decreases to a safe range, the fixed-frequency pulse charging phase begins.
[0012] S5. After the circuit of the fixed frequency pulse stage is reduced to the set value, it enters the small current pulse float charging stage until the battery is fully charged.
[0013] Preferably, the specific operation method in step S1 is as follows:
[0014] The battery is charged with the maximum current matched to the battery, allowing the battery to receive more power per unit time. During this process, the voltage will gradually rise until the voltage of the current stage reaches the set voltage and ends. This stage can charge the battery to about 80% capacity.
[0015] Preferably, the specific operation method in step S2 is as follows:
[0016] Based on the voltage value of S1, the charging current is gradually reduced until it is lower than the set value. This stage is completed, and the reduction in current ensures that the battery can perform incremental charging, thereby reducing the amount of gas evolution and water loss in the battery.
[0017] Preferably, the specific operation method in step S3 is as follows:
[0018] Irregular slow pulses are combined with the high-frequency pulses provided by the equipment to form a combined resonant pulse. By effectively removing the electrochemical polarization and concentration polarization of the battery, the battery temperature rise and water loss are suppressed under relatively high voltage conditions. Sulfation is removed from the battery, and lagging batteries are pulled and charged.
[0019] Preferably, the specific operation method in step S4 is as follows:
[0020] Based on the current reduction of S3, once the current drops to a safe range, the high voltage limit is released, and the stubborn sulfate layer is activated by the instantaneous high voltage stimulation, thus completing the process simultaneously.
[0021] Preferably, based on the entire charging process from steps S1 to S5, when the two electrodes of the charging circuit are connected to the positive and negative electrodes of the battery to be charged, the special electronic pulse waves generated by the process from steps S1 to S5 continuously act on the two electrodes of the battery, changing the movement state of electrons and H+. This causes the lead sulfate crystals solidified on the electrodes in the lead-acid battery to continuously dissociate into Pb2+ and SO42- under the action of the charging pulse electric field. After the two ions dissolve and return to the solution, the solidified and accumulated lead sulfate crystals are removed, the battery plates are in an activated state, the internal resistance decreases, the capacity is restored or partially restored, and the charging efficiency is improved.
[0022] Compared with the prior art, the beneficial effects of the present invention are:
[0023] The lead-acid battery charging, discharging, maintenance, and repair equipment and its usage method utilize a multi-stage composite pulse charging method to slow down sulfation within the lead-acid battery, thereby significantly extending its service life. This reduces the number of batteries that need to be scrapped, saving money and reducing environmental pollution. It also reduces the frequency of battery replacements, greatly improving work efficiency. Attached Figure Description

It has two built-in operating systems: one is an engineer's interface, which is convenient for experienced engineers to compile repair processes; the other is an operator's interface, where operators only need to call the engineer's preset programs. The use of the two systems changes the original repair equipment, which could only use simple and single-function settings to deal with the ever-changing batteries being repaired. It also makes the operation simple and quick for the operator. The high-frequency switching power supply 3 realizes the adjustment of the charging frequency through its own efficiency.
[0035] Specifically, a heater is installed in the rack 1 below the battery storage compartment.
[0036] A heater allows lead-acid batteries to be maintained and charged even in low-temperature environments.
[0037] The equipment and methods for maintaining and repairing lead-acid batteries by charging and discharging include the following steps:

[0042] S5. After the circuit of the fixed frequency pulse stage is reduced to the set value, it enters the small current pulse float charging stage until the battery is fully charged.
[0043] Specifically, the specific operation method in step S1 is as follows:
[0044] The battery is charged with the maximum current matched to the battery, allowing the battery to receive more power per unit time. During this process, the voltage will gradually rise until the voltage of the current stage reaches the set voltage and ends. This stage can charge the battery to about 80% capacity.

[0051] Specifically, based on the entire charging process from steps S1 to S5, when the two electrodes of the charging circuit are connected to the positive and negative terminals of the battery to be charged, the special electronic pulse waves generated by the process from steps S1 to S5 continuously act on the two electrodes of the battery, changing the movement state of electrons and H+.
