How do lithium batteries ensure a long life?

If you want to ensure the long life of lithium batteries, the following points need to be followed: A. Lithium batteries should be reasonably set to charge and discharge protection thresholds; this item seems simple, but it is actually necessary to know the electrochemical characteristics of the cells used Get an appropriate value. A large amount of on-site detection data and careful data decomposition are required. This type of parameter setting is similar to the tuning of the engine and gearbox by an automobile factory. The BMS lithium battery management system is a detailed implementation device for this parameter. The classification of the protection value depends on the load of the battery device; B. The charging temperature of the lithium battery should be controlled, especially the charging temperature at low temperatures; the conventional charging temperature of the lithium battery pack It is 0~45℃. If it is charged below 0°C, due to the low temperature, the nested lithium ions on the negative electrode will appear ion crystallization, which will affect the life and performance. Therefore, it is very meaningful to add a battery heating system to a good insulation facility according to the geographic location of the battery. C. Lithium batteries must be balanced in real time to ensure long life and sufficient power; this principle is well understood. The battery is composed of multiple cells in series and parallel, and the cells are consistent to achieve consistent output and the battery state can be called good.
