A comprehensive quality system for a lithium-ion battery factory involves various elements to ensure the production of high-quality and reliable batteries.
In DLN Energy, the responsibility for product quality issues lies jointly with the technical department and the quality inspection department.
The process is as follows:
The specific composition of our quality system is as follows:
01
Established within the framework of both national and international standards in China, incorporating the demands of the marketing department. These quality objectives are designed to guide, measure, and continually improve the entire production process.
02
Encompasses comprehensive quality planning for all stages of battery production. It involves technical assessments, risk evaluations, and management strategies to identify and mitigate potential issues.
03
Stringent control measures are implemented to ensure the consistency and reliability of the production process.
04
Includes supplier qualification and evaluation procedures to ensure the quality of raw materials and components. Collaboration with suppliers is maintained to uphold consistent quality standards and anticipate future product designs and the introduction of new materials. This prepares us for upcoming developments in new products and materials.
05
A rigorous design and development process is in place to ensure that the batteries meet performance specifications and safety standards.
06
Comprehensive testing protocols cover both raw materials and finished products. Regular inspections are conducted to verify compliance with quality standards.
07
An effective document control system manages and updates quality-related documents, including specifications, procedures, and work instructions.
08
A continuous training program is implemented to ensure that employees have the necessary skills and understanding of quality requirements. Employees are provided with timely competence assessments and skill development plans.
09
A system is in place to capture and analyze customer feedback and complaints.
Case 1: Excessive internal resistance in battery cells.
Case 2: Leakage in battery cells.
10
Implementing continuous improvement methods. Regular reviews and audits are conducted to identify areas for improvement.
11
-A robust traceability system that tracks the status of raw materials, components, and finished products throughout the production process.
Enables quick identification and resolution of quality issues.
12
Compliance with safety and environmental requirements.
-Implementing and maintaining such a comprehensive quality system ensures the production of reliable products in the lithium battery factory. This system aims to meet customer expectations and continuously strive to enhance quality and efficiency.
Evaluation of the performance and stability of lithium batteries under vibrational conditions is essential to determine whether they can operate safely and reliably during transportation or usage.
The details are as follows:
1) Reliability Assessment
By simulating the vibrational conditions that batteries may encounter during actual transportation or usage, it is possible to verify if the battery’s structure and connections are sufficiently secure, thus preventing malfunctions caused by vibrations.
2) Performance Stability
For applications requiring prolonged operation or functioning in vibrational environments, this testing ensures that the battery can maintain stable electrical performance under vibrational conditions.
3) Safety Evaluation
Vibrations may lead to the displacement or damage of internal components within the battery, increasing the risk of battery failure. Testing helps identify potential safety hazards, ensuring that the battery does not pose a danger in vibrational environments.
4) Transportation Compliance
In some countries and regions, the transportation of lithium batteries is subject to specific regulations. Vibrational testing ensures that lithium batteries comply with transportation standards, reducing the likelihood of accidents during transport.
5) Product Optimization
Through vibrational testing, feedback on the design of lithium batteries can be obtained. This aids in continuous improvement of the product’s structure and manufacturing processes, enhancing durability and adaptability.
The quality certificate is a crucial component of our quality system.
