Electric vehicle battery safety needle puncture 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

A puncture test chamber for electric vehicle (EV) battery safety is specifically designed to simulate the battery's response when subjected to external physical damage, such as puncturing by a sharp object. This type of testing is crucial for assessing the battery’s safety and reliability, especially in preventing thermal runaway. Below is a detailed introduction to the EV battery puncture test chamber, including its functions, features, applications, certification requirements, and customization options.

• Assessing Battery Safety: By simulating penetration by a sharp object, this test evaluates whether the battery will undergo thermal runaway or other hazardous conditions.

• Validating Protective Measures: It tests whether the structural design and protective measures of the battery pack or module can effectively prevent internal short circuits and thermal runaway.

• Puncture Device: Utilizes a specially designed needle or probe to penetrate the battery at a set speed and force, mimicking potential physical damage encountered during use.

• Temperature Monitoring: Real-time monitoring of temperature changes within the battery to record peak temperatures and the rate of temperature increase, indicating the risk of thermal runaway.

• Gas Analysis: Detects and analyzes gases produced during the puncture process to assess potential safety hazards.

• Explosion-Proof Structure: Equipped with a robust explosion-proof enclosure to ensure that no explosions or fires occur under extreme conditions, protecting operator safety.

• Automatic Fire Suppression System: Built-in fire suppression mechanisms activate immediately upon detecting flames or smoke.

• Emergency Stop Button: Allows users to quickly interrupt the test in case of emergencies.

• Adjustable Speed and Force: The puncture speed and force can be adjusted according to different types of batteries, simulating various damage scenarios.

• Temperature Control System: High-precision temperature sensors and controllers ensure stable and controlled environmental temperatures during the test.

• Data Acquisition System: Integrated sensors record parameters like temperature, pressure, and current in real-time, facilitating subsequent analysis.

• Exhaust Gas Treatment System: Ensures that harmful gases produced during testing are properly treated, minimizing environmental impact.

• Soundproof Design: Reduces noise pollution, providing a quiet working environment.

• Electric Vehicle Manufacturing: Used to evaluate the safety performance of lithium-ion batteries used in EVs.

• Battery Research and Development: Supports the research and development of new battery materials and technologies, optimizing battery design and manufacturing processes.

• Quality Control: As part of quality assurance, it ensures that each batch of batteries meets safety standards.

To ensure that the EV battery puncture test chamber meets international standards, manufacturers should adhere to the following certifications:

• CE Mark (European Union): Indicates compliance with European health, safety, and environmental regulations.

• UL/ETL (North America): Safety certification issued by Underwriters Laboratories or Intertek Testing Services.

• ISO 9001: Quality management system certification, ensuring consistent provision of products that meet customer and regulatory requirements.

• ISO 14001: Environmental management system certification, demonstrating the manufacturer’s commitment to reducing environmental impact.

• RoHS Directive (European Union): Restricts the use of hazardous substances, ensuring products meet environmental standards.

Based on specific user needs, the following customization features can be considered:

• Size and Capacity: Choose a test chamber size suitable for different battery sizes to accommodate various specifications.

• Additional Functions: Such as remote monitoring, data logging, automated testing procedures, etc., enhancing operational convenience and data management.
