Sodium-ion battery PACK is an integrated complete energy storage system composed of series-parallel cells, with nine core components operating synergistically to undertake energy storage, conduction, control, heat insulation, heat dissipation and protection functions respectively. 1. Energy storage cells: energy carriers of the system, connected in series and parallel according to voltage and capacity demands, including soft pack, square aluminum shell and cylindrical types. 2. Busbars /copper-aluminum connecting sheets: realize conductive series-parallel connection between cells and collect voltage sampling signals. 3. BMS battery management system: the control core of PACK, responsible for monitoring voltage, current and temperature, integrating full software & hardware protection, balancing and communication functions. 4. Insulating separators and heat insulation foam: separate adjacent cells, block heat conduction and insulate against short circuits. 5. Thermal management components: air cooling ducts, water cooling plates and low-temperature heating films to adjust cell operating temperature ranges. 6. High and low voltage harnesses: transmit high-power electric energy and weak signals for temperature & voltage collection. 7. Safety components: high-voltage fuses, relays and waterproof connectors to cut off fault loops via hardware. 8. Metal/plastic structural shells: carry all internal components and resist impact. 9. Waterproof sealing accessories: sealing strips, potting glue and waterproof joints to isolate moisture and dust. The whole system cooperates to complete electric energy storage, safety control, temperature regulation and external power output, applicable to household photovoltaics, industrial & commercial energy storage, electric forklifts and all types of scenarios.
