Most of the battery packs are used in series in different monomers, such as the 24V, forklift battery 48V, the electric car 72V, and through the invested investigations in recent years, there are many battery packs that have not been run under the prescribed electrical parameters. The battery pack is in an abnormal state in which the battery pack is overcharged. The main reason is: the maintenance is not in place, the instrument is not allowed, and the operating parameters are not adjusted in time. Running parameters have a great impact on the life, capacity of the battery pack.
The life of the battery is affected by the floating voltage, and the battery pack floating voltage reaches 100% life during 2.23V, and the life is reduced to 75% when the voltage rises to 2.30 V. The meter measurement is not accurately affected, such as 103 battery packs, according to the factory manual, the floating charge voltage is 2.25V, the battery pack floating voltage is 231.75V, the DC screen voltage gauge indicates 232V, but When the battery was taken out, the battery was found at the time of examination, and most of the batteries were found to operate at 2.20 V, and the actual output voltage of its charging machine was measured after using a voltage meter. Understanding this set of batteries has not been adjusted in 5 years, resulting in the long-term under charge of the battery pack.
