Lithium battery module and lithium battery energy storage device

The invention belongs to the technical field of power supplies, and provides a lithium battery module and a lithium battery energy storage device. The lithium battery module comprises a battery assembly and a BMS battery management system electrically connected with the battery assembly; the battery assembly is composed of a plurality of lithium battery cells in a series connection and/or parallelconnection mode; a specially-designed heat dissipation air duct is arranged between every two adjacent lithium battery cells. And meanwhile, a set of refrigerating system is designed for the lithiumbattery module and the lithium battery energy storage device and is used for refrigerating the system when the lithium battery discharges at a high rate and a high current. According to the lithium battery module provided by the invention, the specially designed heat dissipation air ducts are arranged between the lithium battery cells, so that when the lithium battery module is used, the lithium battery module can be subje
