[0002] Large-scale electrochemical energy storage systems have a fast and bidirectional power regulation function. They are effective facilities and one of the key methods for stabilizing the operation of the power grid and increasing the flexibility and regulation capabilities of the power grid. In particular, they play an important role in the large-scale grid-connected power generation of high-penetration wind power and photovoltaic new energy power, as well as the safety of the sending and receiving ends of high-voltage transmission channels. Large-scale electrochemical energy storage systems play a significant and irreplaceable role in smoothing power support and expanding the utilization rate of transmission channels.

[0003] However, large-scale electrochemical energy storage systems are composed of a large number of small-capacity single cells connected in series and parallel with PCS and BMS to form energy storage unit systems, and are mostly integrated and applied in the form of installation in special container warehouses. For the existing technology, each energy storage unit system is generally 1MWH to 4MWH, composed of tens of thousands of single cells. A large-scale energy storage system of 100 megawatts consists of dozens of energy storage unit systems containing millions of single cells and hundreds of containers. The damage of any single cell may cause immeasurable risks. Therefore, monitoring each single cell and implementing control and maintenance according to the operating status is the basic prerequisite for ensuring the safe and efficient operation of the energy storage system. This requires a large-scale energy storage real-time control system that can quickly respond to real-time regulation and can monitor the status data of each single cell and process massive data.
