Energy storage battery needle puncture safety evaluation test box

FEATURES

1. Pressure, deformation, total voltage or single cell voltage can be used as control variables alone or in combination. When any condition reaches the set value, the test is stopped.

2. After the end of the extrusion test, keep the stroke unchanged, avoiding the expansion of the battery and causing the extrusion head to move back.

Total voltage, cell voltage, temperature, speed, displacement, data recording and data curve

3. The surveillance camera system monitors the shape change of the object during the test in real time and records it in the video database.

4. It can cooperate with the laboratory smoke purification pumping system to discharge the gas and its dust out of the outdoor cleaning and filtering;

5. The experimental area is composed of high temperature resistant, corrosion resistant and flame retardant components. It is designed to enhance the damage caused by fire and explosion during the test and is discharged with the air duct.

6. Remote control monitoring system All control parameter settings, data collection, video recording can be operated by a computer >30m away.

SPECIFICATION

Energy Storage Battery Nail Penetration Safety Evaluation Test Chamber is a specialized equipment used to assess the safety performance of energy storage batteries under nail penetration conditions.‌ The following is a detailed introduction to this test chamber:

‌I. Main Purpose and Working Principle‌

This test chamber evaluates the safety performance of energy storage batteries through a nail penetration test. During the test, a steel nail of a specific diameter is inserted into the battery surface at a certain speed to simulate the scenario where the battery is punctured by a sharp object under unexpected circumstances. Simultaneously, the test chamber monitors the battery's temperature, gas leakage, short circuits, and other states in real time. If the battery does not catch fire or explode after nail penetration, it is considered qualified. This process aims to ensure the safety of the battery when subjected to physical damage.

‌II. Equipment Features‌

1. ‌Precise Control‌

   : The test chamber can precisely control the speed, force, and holding time of the nail penetration to ensure the accuracy and repeatability of the test.

2. ‌Safety Design‌

   : The test chamber adopts explosion-proof, fire-proof, and corrosion-resistant design, equipped with exhaust vents, double-layer explosion-proof glass windows, and an independent controller to ensure safety during the test.

3. ‌Versatility‌

   : Apart from nail penetration tests, some test chambers also support other types of tests such as crushing, to meet the safety performance evaluation needs of different batteries.

4. ‌Data Monitoring and Recording‌

   : During the nail penetration process, the test machine monitors and records various state data of the battery in real time for subsequent analysis.

‌III. Technical Parameters (Example)‌

• Nail Diameter: Typically selectable between 2mm to 8mm, specifically determined according to test standards or customer requirements.

• Nail Penetration Speed: Adjustable, generally within the range of 10mm/s to 40mm/s or wider.124

• Test Chamber Size: Varying based on the model and purpose of the equipment, but usually sufficiently large to accommodate the battery under test.

• High-Temperature Resistance: The steel nail and internal materials of the test chamber must have high-temperature resistance to ensure the accuracy and safety of the test.1

‌IV. Application Fields‌

The Energy Storage Battery Nail Penetration Safety Evaluation Test Chamber is widely used in battery manufacturing enterprises, the automotive industry, and electronic product manufacturers. In the battery research and development stage, it is used to verify the safety of new battery designs; in new energy vehicle manufacturing, it is used to test the compression resistance and safety of power batteries; in consumer electronic product testing, it is used to ensure that internal batteries are not prone to failures due to external impacts.

‌V. Importance‌

The nail penetration test can reveal potential dangers when the battery is subjected to external impacts, helping manufacturers optimize designs and material selections, thereby reducing safety accidents caused by battery failures and protecting consumers' life and property safety. Meanwhile, by using the nail penetration test chamber for regular testing, manufacturers can continuously monitor and improve product quality, ensuring that each batch of batteries meets industry standards and customer expectations.
