Why focus on the field of notebook batteries?

The notebook battery consists of more than just a "cell + casing." It has complex communication protocols. This includes encryption handshakes from HP, Dell, and Lenovo. It has smart battery management systems (BMS). It also includes safety features for charging and discharging. We must invest in research and development for long-term compatibility with these protocols. Focusing on this area keeps the protocol compatible. It also shows battery capacity accurately. This forms a core competitive edge.

How does our quality inspection process work?

1.Incoming material inspection (the battery cells are the first step)

Cell capacity measurement: Each purchased cell undergoes charging and discharging. They group them based on capacity, internal resistance, and voltage without exceptions. Only consistent parameter cells can pair. This is key for the battery pack's durability.

Protection Board Testing: Test the B

2. Process Control in Production

Spot Welding Quality Inspection: Inspectors assess the strength of the battery cell connection plates. This helps prevent false welding, which can lead to overheating during use.

Insulation test: Perform high-voltage tests on important circuit parts. This checks for any leakage risks.

Send the first assembled product of each new model to the dedicated equipment. This is for the initial confirmation of the agreement. It needs thorough testing of its communication protocol. Also, it should test the charging and discharging curve with the right notebook. Only when everything is normal can we allow mass production.

3. Final product inspection (Every piece must pass)

This step is vital before the product leaves the factory. It’s done by computers without any involvement from humans.

Static Parameters:

• Ensure the voltage is within the standard range.
• Check that the internal resistance is acceptable
• Verify the temperature sensor is functioning properly
• Communication handshake:
  • Simulate the machine startup
  • Confirm the battery is recognized
  • Check that the battery percentage is accurate
  • Ensure the production cycle and cycle count are correct

Basic Charge and Discharge: Run a short cycle to check if the charge and discharge process is stable. Also, see if the protection board cuts off the power supply when the battery is nearly fully charged.

Check the appearance: Look for gaps, scratches, or misaligned labels on the casing.

4. Aging and Stability Testing

Place fully inspected and qualified batteries in an aging room designed for high temperatures. Keep the temperature between 40-45℃. Leave them fully charged or at a high voltage for several hours, and check the voltage drop. This step helps quickly remove products with small short circuits or high self-discharge.

Re-measurement: After aging, measure the voltage resistance again. Then, conduct the final communication test. Cut the nonconforming products with parameter drift.

5. Sampling reliability verification (destructive and environmental tests)

The quality department will randomly choose samples from each batch. This helps simulate extreme scenarios and check the reliability of the whole batch.

Cycle life test: Charge and discharge repeatedly for hundreds of cycles. This checks if the capacity decline matches the nominal value.

Safety Test: The battery must pass several tests:

• Overcharging
• Forced short circuiting
• Temperature shock: This means a sudden drop from 80℃ to -40℃
• Compression
• Puncture

It must not catch fire or explode during these tests.

Drop and vibration: Simulate unexpected drops during transportation and usage

A battery can only be packaged and shipped after passing all these checkpoints.
