The working principle of lead-acid batteries
The charging and discharging process of lead-acid batteries is an electrochemical reaction. When charging, lead sulfate forms lead oxide, and when discharging, lead oxide is reduced to lead sulfate. Lead sulfate is a substance that is very easy to crystallize. When the concentration of lead sulfate in the electrolytic solution of the battery is too high or the static idle time is too long, it will “hug” into clusters and form small crystals. These small crystals attract the surrounding area. The lead sulfate forms large inert crystals like a snowball. The crystallized lead sulfate can not be reduced to lead oxide when it is charged. It will also precipitate and adhere to the electrode plate, resulting in a decrease in the working area of the electrode plate. This phenomenon is called Vulcanization, also known as aging. At this time, the battery capacity will gradually decrease until it becomes unusable. When a large amount of lead sulfate is piled up, it will attract lead particles to form lead branches. The bridge between the positive and negative plates will cause the battery to short circuit. If there are gaps on the surface of the electrode plate or the sealed plastic case, lead sulfate crystals will accumulate in these gaps and generate expansion tension, which will eventually cause the electrode plate to break off or the shell to rupture, causing irreparable physical damage to the battery. Therefore, the main mechanism leading to lead-acid battery failure and damage is the unavoidable vulcanization of the battery itself.
At present, the service life of domestic lead-acid batteries is generally about 600 times of charge and discharge. With the passage of time, the capacity of the battery will become less and less. However, the motor power of the electric stacker will not change. Therefore, with the same power consumption, the battery capacity is small, which will reduce the use time, which is commonly known as “the battery cannot be charged.” In fact, it is not that the battery cannot be charged, but that the battery is a normal aging condition. At this time, the battery is not only unsatisfied with charging, but the amount of power (degrees) required for charging at the same time is still the same as the previous consumption, and normal energy conversion cannot be achieved. Even if the old battery is fully charged, the service time is far less than that of the new battery. In order to maintain the normal use of the electric stacker, a new set of batteries needs to be replaced at this time to cope with the daily use of the electric stacker.
