Core Parameters of Cells and Battery Packs
Cell Specification: 32700 model lithium iron phosphate (LiFePO4) cells are adopted. This type of cell has the advantages of high safety (thermal runaway temperature ≥200℃), long cycle life (capacity retention rate ≥80% after 1000 cycles), and no memory effect, making it suitable for various application scenarios such as energy storage, power tools, and low-speed electric vehicles.
Maximum Cell Parameters: The rated voltage is 3.2V, the maximum voltage is 3.6V, the maximum capacity is 6500mAh, and the energy density is ≥150Wh/kg, which can meet the battery life and power supply requirements in high-capacity demand scenarios.
Battery Pack Configuration: A 4S7P series-parallel structure (4 in series and 7 in parallel) is adopted. The 4-series design enables the battery pack to have a rated voltage of 12.8V (3.2V×4), and the 7-parallel design enables the battery pack to have a capacity of 45.5Ah (6500mAh×7). The overall battery pack energy is ≥582Wh. The series-parallel structure can be adjusted according to customer needs to adapt to different voltage and capacity requirements.
Production Capacity and Quality Assurance
Daily Production Capacity: The assembly line is designed to have a daily production capacity of 70-75 battery packs. Calculated based on 300 working days a year, the annual production capacity can reach 21,000-22,500 battery packs, which can meet the production needs of medium and large-scale customers. At the same time, the equipment supports modular expansion. In the future, according to the customer's demand for production capacity improvement, equipment channels can be increased or new production lines can be added to realize flexible production capacity upgrading.
Quality Control: A "three-level quality inspection system" is established, covering incoming inspection of raw materials (cells), online inspection of each process in production, and aging testing and comprehensive testing of finished products. It ensures that the qualification rate of each battery pack leaving the factory is ≥99.5%. In addition, we provide equipment operation training, regular maintenance and other services to help customers stabilize the production process and continuously ensure product quality.
