Description

technical field [0001] The present application relates to the field of batteries, in particular to an energy storage system. Background technique [0002] With the development of lithium-ion battery technology, lithium-ion batteries are more and more widely used in communication power supplies, data centers, micro-grid energy storage, electric vehicles and other fields. With the maturity of technology and technology, the capacity of single battery cells gradually increases. At present, the large-capacity batteries in the industry have reached about 300 ampere hours (Ah), but compared with lead-acid batteries, the capacity is still small, so it generally requires multiple parallel applications. When current electric vehicles and energy storage use lithium batteries, the cells are usually connected in series and parallel to form a standard PACK module, and then the standard PACK module is assembled into the installation space of the energy storage cabinet, rack, electric vehi...
