Problems solved by technology
The disadvantage of the prior art battery pack management system for mine power supply is that when the master control machine breaks down unexpectedly, all slave control machines will be unable to operate, resulting in the paralysis of the entire battery pack management system
In other words, the prior art battery pack management system for mine power supply has poor stability
If you want to restore the entire battery pack management system, one method is to manually reset the main control unit, which requires high labor costs; the other method is to add a main control unit as a backup main control unit to improve the overall battery life. The stability of the battery pack management system reduces the failure rate of the main control unit. This method leads to a more complex structure of the battery pack management system and a corresponding increase in its cost

Embodiment Construction
[0032] The content of the invention of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0033] Such as figure 2 As shown, the battery pack management system for mine power supply provided by this embodiment includes a field bus and multiple battery packs connected to the field bus, that is, multiple battery packs are electrically connected to the field bus. The plurality of battery packs are located at the same logical level and are independent of each other. Each battery pack has a unique numerical identifier to distinguish different battery packs. Each battery pack includes multiple Li-ion battery cells and a memory. In this embodiment, the battery pack management system for mining power supply includes, for example, seven battery packs, namely battery pack 1, battery pack 2, battery pack 3, battery pack 4, battery pack 5, battery pack 6 and battery pack 7. The numerical identifiers for Battery Pack 1...

The invention discloses a battery pack management system and a battery pack management method for a mining power supply. The battery pack management system comprises a field bus and a plurality of battery packs connected into the field bus, wherein the battery packs are located in the same logic level, and are mutually independent, and each battery pack has a unique digital identifier, and comprises a plurality of lithium ion battery cells and a storer. With the adoption of the battery pack management system and the battery pack management method, when the main battery packs break down, the slave battery packs can campaign for and confirm new main battery packs again according to a campaigning rule, so that breakdown of the whole battery pack management system is avoided; the stability of the whole battery pack management system is improved significantly; the structure of the battery pack management system is simplified; and the maintenance cost of the battery pack management system is lowered effectively.
Description
technical field [0001] The invention relates to the technical field of mine power supplies, in particular to a battery pack management system for mine power supplies and a management method thereof. Background technique [0002] The emergency escape cabin or refuge chamber used in underground coal mines is a sealed escape refuge, which is used to provide a safe space environment for maintaining life. When there is an emergency in the coal mine, the miners can enter the emergency rescue cabin or refuge chamber in time to avoid danger, so as to ensure the safety of absenteeism. [0003] With the continuous development of emergency rescue cabins or refuge chambers, coal mine underground equipment such as monitoring and monitoring systems, emergency avoidance facilities, and auxiliary transportation equipment have higher and higher requirements for mine power supplies. Lithium-ion batteries with high energy ratio and no memory effect The battery has become one of the best choic...
