The safety of the battery is mainly controlled in several aspects: during the cell manufacturing process, during the battery pack integration process, during the storage process, during the transportation process, during the use process, during the recycling process and material extraction.
But in fact, this is difficult to achieve. The important thing is that lithium-ion battery packs place multiple single lithium-ion batteries in a small space, and it is difficult to ensure that each lithium-ion battery can dissipate heat well.
At the same time, due to the different environments of various lithium-ion batteries, their heating conditions are also different. This greatly increases the difficulty of lithium-ion battery management.
It can be seen that the safety problem of lithium-ion battery packs can be solved, and safety accidents can be minimized by adopting safer single lithium-ion batteries, rationally arranging lithium-ion battery structures, and powerful lithium-ion battery management systems. probability of occurrence.
In practical applications, due to differences between battery packs, a single cell in the battery pack will fail first, which will form a domino effect, resulting in the failure of the entire battery pack, seriously affecting the safety and service life of the lithium-ion battery pack. .
