Lithium Battery Washing Test Machine | GB 31241 Battery Washing Test Chamber

The Lithium Battery Washing Test Machine is designed to simulate the mechanical and thermal stresses that lithium battery packs may encounter if accidentally washed. It reproduces a realistic washing process, including soaking, agitation, spinning, and dehydration, under controlled laboratory conditions.

This equipment helps manufacturers and testing laboratories assess potential risks such as sealing failure, electrolyte leakage, or structural damage after exposure to washing conditions. It is particularly relevant for batteries used in smartphones, wearables, Bluetooth devices, power banks, and other portable electronics.

Technical Parameters

Professional Construction & Technical Precision

The Lithium Battery Washing Test Machine features a robust SUS304 stainless steel inner chamber and a servo-driven rotating turntable. This design ensures stable mechanical agitation and repeatable test conditions. The PLC control system allows precise management of temperature, rotation speed, and test duration.

The equipment is built for long-term laboratory use with good corrosion resistance and a practical structural layout that supports efficient testing workflows.

Testing Principle

During the test, the battery pack is securely fixed on the rotating turntable inside the test chamber to ensure stable positioning throughout the washing cycle. After the test program starts, the equipment automatically performs controlled procedures including water filling, detergent or test solution heating, soaking, mechanical agitation, drainage, and spin dehydration. These steps simulate the combined effects that a battery pack may experience when accidentally exposed to a washing-machine-like environment.

The test chamber provides a controlled environment with moisture, temperature, rotation, and mechanical movement. Through continuous soaking, agitation, and centrifugal dehydration, the battery pack is exposed to both water contact and repeated mechanical stress. This allows the operator to evaluate whether the enclosure, sealing structure, insulation system, electrical connections, and overall assembly can maintain integrity under harsh washing conditions.

By reproducing accidental washing scenarios in a repeatable way, the machine helps manufacturers assess the durability and safety performance of lithium battery packs used in portable electronics, wearable devices, smart equipment, and other consumer applications. After testing, the battery pack can be inspected for water ingress, deformation, leakage, insulation failure, abnormal voltage change, short-circuit risk, or other visible and electrical abnormalities.

Common Error Mitigation

To obtain accurate and reliable test results, the following practices are recommended:

• Ensure battery packs are properly secured on the turntable before starting the test.
• Verify that test parameters (temperature, speed, and duration) match the required protocol.
• Confirm that the chamber door is securely closed and safety interlocks are functioning.
• Monitor the test process and check for any abnormal conditions during operation.
• Regularly inspect and maintain the rotating mechanism and sealing components.
• Record all test parameters and results for traceability.
