In the huge system of industrial machinery, the choice of power source is very important, and its performance directly determines the efficiency, stability and sustainable operation of the machine. As a time-tested and widely used power source, traction lead-acid battery plays a key role as a long-term power provider in the industrial field with its unique advantages, injecting strong and lasting power into the stable operation of various industrial machinery.

1.The working principle of lead-acid battery cornerstone

The work of lead-acid batteries is based on a complex and exquisite electrochemical reaction mechanism. The electrode is mainly composed of lead and its oxide, and the electrolyte is sulfuric acid solution. In the discharge process, the lead on the negative plate reacts with sulfate ions in the electrolyte to form lead sulfate, and releases electrons, which flow to the positive electrode through the external circuit to form a current. On the positive plate, lead dioxide reacts with electrons and hydrogen ions in the presence of sulfuric acid to also form lead sulfate and water. When charging, the process is reversed, the lead sulfate is broken down under the action of an electric current, so that the electrode active material is restored, and the battery is re-stored. This reversible electrochemical reaction process lays the foundation for the continuous and stable energy supply of the lead-acid battery for industrial machinery, and its stable reaction characteristics ensure that the power can be reliably output under different working conditions.

2.Adapt to the outstanding characteristics of the industrial environment

(1) High rate discharge performance

When industrial machinery is running, it is often faced with high load requirements such as instantaneous start and acceleration, and the traction lead-acid battery has excellent high rate discharge capacity, which can release strong current in a short time to meet the demand for instantaneous large torque output of machinery. For example, in a forklift operation scenario, the forklift needs to move goods frequently and quickly. When the forklift is stationary, it starts quickly and lifts heavy objects. The lead acid battery can respond quickly to provide strong power to ensure the smooth and efficient operation of the forklift, greatly improve the working efficiency, and avoid slow start or stagnant handling caused by insufficient power.

(2) Good low temperature performance

Many industrial environments have large temperature fluctuations, especially in cold areas or low-temperature places such as cold storage, and the performance of the power source is easily affected. The traction lead-acid battery can maintain good discharge performance under low temperature environment through special plate formulation and electrolyte optimization. At low temperature, its electrochemical reaction will slow down, but with reasonable design, it can still stably output enough power to ensure the normal operation of industrial machinery. For example, electric transport vehicles in cold chain logistics, even if shuttling in low temperature cold storage and normal temperature areas, rely on the traction of lead-acid batteries, but also sustainable operation, will not be greatly shortened due to low temperature or reduce power, to maintain the efficient operation of cold chain logistics.

(3) The structure is strong and durable

The industrial working environment is complex, and the machinery is often shaken, jolted and impacted. The traction lead-acid battery has a robust housing design and internal structural reinforcement measures to withstand severe mechanical stresses. The plate is made of special technology, which enhances the mechanical strength and is not easy to be deformed or damaged in vibration. In harsh environments such as mines and construction sites, the construction machinery and equipment loaded with lead-acid batteries can still work stably even if they travel on bumpy roads and experience frequent shocks and shocks, providing continuous power for the equipment, reducing the downtime and maintenance time caused by battery failure, and ensuring the continuity of industrial production.

3. Long life design and cost effectiveness

(1) Technical means to extend battery life

Traction lead-acid batteries are designed to extend service life, using high purity raw materials, advanced grid alloy technology and optimized production processes. High purity raw materials reduce the interference of impurities on the internal reaction of the battery, reduce the self-discharge rate, and extend the static storage time of the battery. Advanced grid alloys enhance corrosion resistance, slow the corrosion rate of the plate during the charge and discharge cycle, and significantly increase the battery cycle life. Taking tubular plate technology as an example, its unique structure effectively protects active substances, reduces falling off, significantly increases the number of battery charging and discharging cycles, and some high-quality traction lead-acid batteries can have a cycle life of thousands of times, providing long-term stable power protection for industrial machinery.

(2) Full life cycle cost advantage

From a full life cycle perspective, the traction of lead-acid batteries shows outstanding cost effectiveness. Although its initial acquisition cost may be slightly higher than that of some newer batteries, its long life features allow for a significant reduction in annual costs over the long term. At the same time, its maintenance technology is mature and the maintenance cost is low. Industrial enterprises do not need to invest a lot of money for complex maintenance equipment and professional technical training, ordinary maintenance personnel can carry out daily maintenance after simple training, such as regularly checking the electrolyte level, specific gravity, cleaning the battery surface and so on. In contrast, although the initial cost of some new batteries is low, the life span is short, the maintenance is complex, and the comprehensive life cycle cost is much higher than that of the traction lead-acid battery, making it an economical and long-term choice for the power configuration of industrial machinery.

4. Wide application and continuous innovation

(1) Deep penetration of diverse industrial scenes

In the industrial field, traction lead-acid batteries are widely used. In addition to forklifts, construction machinery and equipment, it also occupies a dominant position in the fields of electric sightseeing vehicles, warehousing logistics trucks, and golf carts. In large logistics storage centers, electric pallet trucks rely on lead acid batteries to move goods flexibly between shelves to achieve efficient storage management. In tourist attractions, electric sightseeing vehicles are equipped with traction lead-acid batteries to provide tourists with comfortable and convenient sightseeing services, and its stable power ensures that the vehicle runs smoothly in different road conditions in the scenic spot. These application scenarios fully demonstrate the good adaptability of traction lead-acid batteries to the needs of diverse industrial operations.

(2). Technological innovation drives development

In the face of energy transformation and market demand upgrading, the lead-acid battery industry continues to innovate. On the one hand, the development of new additives to improve the performance of the electrolyte, improve the battery charging and discharging efficiency and low temperature performance; On the other hand, more advanced production processes are explored to further improve battery consistency and reliability. At the same time, the battery management system (BMS) is continuously optimized, and the charging and discharging process is accurately controlled by real-time monitoring of battery voltage, current, temperature and other parameters, preventing overcharging and overdischarge, extending battery life, and improving the safety of use. In addition, with the development of intelligent trends, intelligent traction lead-acid batteries are gradually coming out, which can realize remote monitoring and data analysis, provide strong support for industrial enterprise equipment management, make it better integrated into the industrial 4.0 intelligent production system, and continue to consolidate its long-term position in the field of industrial machinery power source.
