As the core energy storage component in scenarios such as power systems, communication equipment, and emergency power supply, the operational stability of storage batteries (battery banks) directly determines the reliable operation of related systems. Daily inspection and maintenance are crucial links to extend the service life of storage batteries, prevent equipment failures, and ensure energy storage performance. It is necessary to follow scientific and standardized operating procedures, cover all dimensions including environmental control, safety protection, patrol inspection, and parameter monitoring, and implement various maintenance measures in combination with actual operating conditions to ensure that storage batteries (battery banks) are in good working condition for a long time. Combining the maintenance practice of storage batteries (battery banks), this article elaborates on the core points and operating specifications of daily maintenance, providing professional guidance for on-site maintenance work.
The daily maintenance of storage batteries (battery banks) must adhere to the principle of "prevention first, combination of prevention and treatment", focusing on environmental management, safety control, patrol inspection, parameter monitoring, and maintenance operations. Each maintenance work must strictly follow industry standards and equipment specifications to avoid safety hazards and equipment damage caused by irregular operations.
Environmental conditions are important factors affecting the performance and service life of storage batteries. It is necessary to focus on controlling cleanliness, temperature and humidity, ventilation, and lighting conditions to provide a stable operating environment for storage batteries (battery banks).
First of all, it is necessary to keep the battery room clean and hygienic, and regularly clean the dust on the ground, walls, and equipment surfaces to prevent dust from entering the interior of the storage batteries or adhering to the terminals, so as to avoid poor contact, reduced insulation, and other problems. Secondly, the room must be kept dry and ventilated, which can not only effectively reduce the humidity in the air, prevent corrosion of the battery case and oxidation of the terminals, but also timely discharge the hydrogen gas generated during the charging process, reducing safety risks; at the same time, it is necessary to ensure sufficient indoor light to facilitate maintenance personnel to carry out patrol inspections, but direct sunlight on the surface of the storage batteries should be avoided to prevent aging of the battery case and abnormal increase in the temperature of the internal electrolyte, which affects battery capacity and service life.
Temperature control is the core point of environmental maintenance. The optimal operating temperature for storage batteries (battery banks) is 5~25℃. Too high temperature will accelerate electrolyte loss and shorten battery life, while too low temperature will reduce battery activity and affect discharge capacity. When the room temperature is lower than 5℃, appropriate thermal insulation measures should be taken for the storage batteries, and the room temperature can be maintained stably by installing thermal insulation layers and activating constant temperature equipment; when the room temperature is higher than 25℃, ventilation and heat dissipation should be strengthened to avoid potential safety hazards caused by continuous temperature rise.
Storage batteries (battery banks) generate hydrogen gas during charging, which is a flammable and explosive gas, and the battery contains corrosive electrolyte. Therefore, strict safety protection measures must be implemented in daily maintenance to prevent safety accidents such as fire, electric shock, and corrosion.
Open flames are strictly prohibited in the battery room, and it is forbidden to carry fire sources and flammable and explosive items into the room. Especially when the storage batteries are in the charging state, any open flame operation is strictly prohibited. At the same time, warning signs such as "No Open Flames" and "Caution Explosion" should be posted in prominent positions in the room, sufficient fire-fighting equipment should be equipped, and the effectiveness of the fire-fighting equipment should be checked regularly.
When carrying out maintenance or battery replacement operations, maintenance personnel must wear personal protective equipment such as goggles and anti-corrosion gloves to avoid corrosive damage caused by electrolyte contact with the skin and eyes; insulating instruments and tools with insulating sleeves (such as insulating wrenches, insulating screwdrivers, etc.) must be used during operation to prevent short circuits caused by tools contacting the positive and negative electrodes of the battery, and to avoid electric shock to personnel. During the operation, the operation should be standardized, and rough operation is strictly prohibited to prevent damage and leakage of the storage battery.
Daily patrol inspection is the key to timely detecting abnormalities of storage batteries (battery banks). Comprehensive patrols must be carried out regularly, focusing on checking the battery appearance, wiring status, etc., to ensure that problems are found and handled early.
First, check the surface state of the storage battery and keep the battery surface clean and dry. If corrosion, leakage, depression, or bulging is found on the battery case, relevant operations should be stopped immediately, the abnormal battery should be handled in a timely manner, and the cause should be thoroughly investigated to check for overcharging, abnormal temperature, improper installation, and other problems to avoid the expansion of abnormalities. Second, check the connecting screws between the battery cells to ensure they are tightly connected, preventing increased contact resistance caused by looseness, which leads to local overheating and affects the overall operating performance of the battery bank; if loose screws are found, they should be tightened in a timely manner, and the force should be controlled during tightening to avoid damage to the terminals.
In addition, it is necessary to regularly check the installation and fixation of the battery bank to ensure that the battery bank is neatly arranged and firmly fixed, avoiding battery damage or wiring detachment caused by vibration and collision; at the same time, check the operating status of the indoor ventilation equipment and thermal insulation facilities to ensure they play a normal role.
The operating parameters of storage batteries (battery banks) directly reflect their working state. It is necessary to regularly monitor key parameters such as floating charge voltage to timely detect parameter abnormalities and ensure the stable operation of the battery bank.
In daily maintenance, it is necessary to frequently check the on-line floating charge voltage of the storage battery and the total floating charge voltage (terminal total voltage) of the battery bank, and compare the monitored data with the data displayed on the equipment panel. If a large deviation is found in the data, the cause should be investigated in a timely manner, and the panel display should be corrected if necessary to ensure the accuracy of the monitored data. At the same time, the monitored data should be recorded and a maintenance account should be established. By comparing the parameter changes in different periods, the operating trend of the storage battery (battery bank) can be analyzed, and potential faults can be predicted in advance.
In the daily maintenance process of storage batteries (battery banks), it is necessary to strictly abide by operational taboos to avoid equipment damage or safety accidents caused by irregular operations. During normal use, no organic solvents shall be used to clean the battery to prevent organic solvents from corroding the battery case and seals, leading to leakage; the safety valve of the battery must not be disassembled, and no substances shall be added to the battery, so as not to damage the internal structure of the battery, affect battery performance, or even cause safety hazards; the battery should be charged as soon as possible after discharge to avoid the battery being in a state of undercharge for a long time, preventing plate sulfation and affecting battery capacity and service life.
For storage batteries (battery banks) that have been out of service for more than 3 months, special maintenance is required. Before being put into operation again, supplementary charging should be carried out first to ensure that the battery capacity is restored to the normal level, avoiding battery performance degradation caused by long-term inactivity and affecting the normal power supply of the system. Supplementary charging must follow standardized procedures, control the charging voltage and current, and avoid battery damage caused by overcharging.
Daily inspection and maintenance of storage batteries (battery banks) is the core work to ensure their reliable operation and extend their service life. It is necessary to implement various maintenance measures in combination with environmental management, safety protection, patrol inspection, parameter monitoring, and other aspects, strictly follow operating specifications, and eliminate irregular operations. Maintenance personnel must have professional operating skills and safety awareness, carry out maintenance work regularly, establish a complete maintenance account, and timely investigate and handle various abnormal problems to ensure that storage batteries (battery banks) are always in good operating condition, providing reliable energy storage guarantee for the stable operation of related systems. At the same time, with the continuous development of battery technology, it is necessary to optimize maintenance plans in combination with the characteristics of new-type storage batteries, and improve the professionalism and effectiveness of maintenance work.
