Large-scale power storage technology is the key technology for smart grid, new energy generation and grid connection, power load shifting and valley filling. Lithium-ion batteries have been widely used in many fields due to their high energy density, low self-discharge rate, smooth discharge voltage, long cycle life and other advantages, and the application of lithium batteries in large-scale power storage systems will become an inevitable trend in technology development. In order to ensure the efficient and safe application of lithium-ion solar battery storage (Battery Energy Storage System, BESS), all components of the system must be integrated and optimized, and managed and controlled in a reasonable and effective manner.
The battery management technology and system integration technology of energy storage systems can be developed to improve the safety, reliability and service life of the battery system and promote the popularization and application of large-scale power storage. The key technologies include:
(1) advanced battery management technology ;
(2) temperature monitoring and management technology;
(3) state of health (SOH) monitoring technology;
(4) system integration technology.
