Integrated Management Technology of Electrochemical Energy Storage Batteries

　　Integrated management technology of electrochemical energy storage batteries aims to comprehensively manage all aspects of battery operation, including monitoring, control, protection, and optimization, to ensure the safe, reliable, and efficient operation of energy storage systems.

　　At the core of integrated management is the battery management system (BMS). The BMS is responsible for real - time monitoring of key battery parameters such as voltage, current, temperature, SoC, and SoH of each battery cell or module in a battery pack. It uses sensors and data acquisition units to collect this information and then processes it using advanced algorithms. Based on the monitored data, the BMS can perform functions such as cell balancing. In a battery pack, individual cells may have slight differences in capacity, internal resistance, and voltage, which can lead to uneven charging and discharging. The BMS equalizes the state of charge of each cell through techniques like passive or active cell balancing, ensuring that all cells operate in a more uniform manner and extending the overall lifespan of the battery pack.

　　Another important function of the integrated management technology is protection. It safeguards the battery from over - charging, over - discharging, over - temperature, and short - circuit conditions. When abnormal conditions are detected, the BMS can take immediate actions, such as disconnecting the battery from the load or the charging source, to prevent damage to the battery and potential safety hazards. In addition, the integrated management system can optimize the operation of the battery in relation to the overall energy storage system. It can coordinate with other components in the system, such as the power conversion system and the energy management system, to manage the flow of energy, respond to grid demands, and integrate renewable energy sources more effectively. For example, when there is an excess of renewable energy generation, the BMS can control the charging of the battery to store the surplus energy, and when the grid needs power, it can manage the discharge process to supply the required energy in a stable and efficient manner. With the continuous development of technology, integrated management technology is becoming more intelligent and capable, playing an increasingly important role in the widespread application of electrochemical energy storage batteries.
