[0003] The battery energy storage system includes multiple energy storage battery packs (PACK). The battery management unit (BMU) is a key component of the energy storage battery system and is used to monitor and manage the energy storage battery system. With the rapid development of the energy storage industry in recent years, the structure of the energy storage battery pack has undergone multiple iterations and updates. The air-cooled energy storage battery pack is widely used in various scales and types of energy storage systems because its structure is simpler than the liquid-cooled solution and the production and manufacturing cost is lower.
