The forklift battery is a traction battery. It is used in series with multiple 2V units. The difference in capacity and consistency of the unit determines the subsequent discharge and charge acceptance of the entire battery. The battery pack has different characteristics from the single battery. At present, the battery design and manufacturing technology level, the performance difference between the monomers exists objectively throughout its life cycle, in order to avoid the premature failure of the monomer due to overcharge and overdischarge, so that the function and performance indicators of the battery pack reach or approach The average level of the monomer is the only way to achieve scientific management of the charge and discharge of the battery pack.

At present, it is computer cloud management. It can manage the voltage, capacity, density and temperature of the forklift battery by data management to avoid the subsequent differentiation. The service life of the battery pack is affected by many factors, if the battery pack has a low life. Below half of the average life of the monomer, it can be inferred that it is caused by improper use of technology. The primary reason is that the battery fails prematurely when the charge and over discharge are pushed. The power management technology is very perfect, but in the battery pack, the difference between the monomers always exists. Taking the capacity as an example, the difference will never disappear, but gradually deteriorate. The same current flows through the group. Relatively speaking, the larger the capacity is always in the shallow current of shallow current, the slower the capacity decay, the longer the life, and the smaller the capacity is always in the high current overcharge and over discharge, tending to capacity decay. Accelerated and shortened lifespan, the difference in performance parameters between the two is getting larger and larger, forming positive feedback characteristics, small capacity premature failure, and group life is shortened.
