An exceptional battery pack is not only the result of high-quality cell materials but also depends on a rigorous, precise, and traceable production process system. Today, we are releasing our internal ”Battery Pack Production Process Flowchart” to take you behind the scenes and reveal how a high-quality battery pack passes through layer upon layer of quality checks before it is finally delivered to our customers.

ODIPIE Lithium-Ion Battery Production Process

1. Battery Cell Matching: First, the cells undergo consistency screening and matching to ensure parameters such as voltage and internal resistance are consistent, laying the foundation for subsequent assembly.

2. Cell Insulation: The matched cells undergo insulation treatment, wrapped in epoxy board insulation material to prevent the risk of short circuits between cells.

3. Laser Welding: Using laser welding technology, the cells are securely connected into a pack, ensuring connection stability and electrical conductivity.

4. Data Cable Attachment: Data cables are attached to the welded cell packs to provide signal collection points for subsequent BMS management.

5. Battery Management System (BMS) Mounting: The BMS is securely mounted onto the cell pack to ensure a stable installation and provide the hardware foundation for battery safety management.

6. Positive and Negative Terminal Wiring: The positive and negative terminal wiring of the battery pack is secured and reinforced to ensure stable and reliable current transmission.

7. Battery Insulation: The entire battery pack is wrapped again with epoxy board insulation to further enhance the overall insulation protection rating.

8. Battery Internal Resistance Testing: Conduct internal resistance testing on the assembled battery pack to verify that the internal resistance of the cell assembly meets standards.

9. Battery Aging Testing: Perform long-term charge-discharge aging tests on the battery pack to simulate actual operating conditions and identify early defects.

10. Enclosure Assembly / Securing Positive and Negative Terminals: The battery pack is assembled into the enclosure, and the positive and negative terminals are securely fastened, completing the initial product assembly.

11. Battery Functional Testing: Comprehensive functional testing is performed on the finished battery, including protection functions and communication capabilities, to ensure all specifications are met.

12. Enclosure Sealing: The battery enclosure is sealed to enhance waterproofing and dustproofing performance, meeting the protection requirements of various application scenarios.

13. Vibration Testing: Subject the finished batteries to vibration testing to simulate the vibration environments encountered during transportation and use, verifying the structural stability of the product.

14. High and Low Temperature Testing: Test the batteries in high and low temperature environments to verify their performance and safety under extreme temperature conditions.

15. Packaging / Palletizing: After final inspection, professionally package the batteries and stack them onto pallets to ensure safe delivery to the customer.

ODIPIE Lithium-Ion Battery Production Quality Control Process:

1. Order and Material Preparation Control: Once an order is confirmed, a production plan is issued, and material procurement is initiated simultaneously; All materials must undergo incoming quality control (IQC) before entering the facility; non-conforming materials are rejected outright, and only those that pass inspection are stored in the warehouse.

2. First-Article and Process Validation: After material preparation is complete, the first production unit is manufactured and undergoes comprehensive performance testing; simultaneously, process SOPs and industry certification standards are validated. Only when both the first-article and the process meet standards is mass production permitted.

3. Cell Batching and Sorting: Cells are grouped according to stringent standards, requiring a voltage difference of ≤±2 mV and an internal resistance difference of ≤±0.1 mΩ. This ensures cell consistency from the source, laying the foundation for stable battery operation.

4. Assembly and Welding Control: After laser welding of the cells, the tensile strength of the connection tabs (5% random inspection, ≥50 kg) and the lead wires (≥5 kg) is strictly tested. Solder joints on the lead wires must be reinforced with adhesive to eliminate the risk of cold solder joints or solder joint failure.

5. Full-Process Quality Inspection During Assembly: After welding, the cable harness is organized, the BMS (Battery Management System) is secured, and the positive and negative terminals are neatly routed. Simultaneously, the battery pack undergoes multi-layer insulation treatment, with installation accuracy and safety verified at every step.

6. Electrical Performance and Cycle Testing: After the battery pack is fully assembled, first verify that the internal resistance meets specifications; then conduct charge-discharge aging cycle tests (process: discharge to empty → fully charge → discharge to empty → charge to 70% SOC) to screen out early defects and ensure the battery’s cycle life.

7. Functional and Final Inspection: After passing the aging test, a full functional test of the battery is conducted. Following casing, a final visual inspection is performed to ensure no scratches or adhesive overflow, no oxidation on the terminals, and a centered nameplate with no creases; non-conforming products are reworked.

8. Packaging and Shipping Verification: Qualified products are sealed, packed, and arranged on pallets. After warehousing, they undergo a final commercial inspection; once confirmed, shipping is arranged, with the entire process traceable through documentation.
