As the application fields of lithium battery packs continue to expand, their market demand is also expanding.

The inventor noticed that thousands of lithium battery packs are stored in lithium battery warehouses for a long period of time. Since lithium battery packs have self-discharge characteristics, the lithium battery packs in the warehouse need to be recharged, balanced and otherwise maintained. In the traditional technical solution, warehouse staff regularly perform maintenance such as recharging and balancing all lithium battery packs in the warehouse; however, the number of lithium battery packs in the warehouse is large and the storage is intensive. The traditional maintenance process of lithium battery packs It is blind, has a huge workload, and wastes a lot of manpower and material resources.

In order to monitor the battery status of lithium battery packs stored in lithium battery warehouses, the inventor found that the battery management system can detect the battery information of each battery cell in the lithium battery pack, that is, the battery in the lithium battery pack can be used The management system obtains the battery information of the lithium battery pack, and then analyzes the obtained battery information to monitor the battery status of the lithium battery pack. However, the battery management system needs to be powered on before it can send the battery information of the lithium battery pack; directly putting the lithium battery pack in working order to power the battery management system will waste a lot of power resources.
