2026 High-Voltage Lithium Battery Certification System, Testing Standards, and Export Requirements
As an important power source of modern electric vehicles, energy storage systems and consumer electronics products, high-voltage lithium batteries are increasingly valued for their safety, performance and environmental adaptability. With the rapid growth of global demand for high-voltage lithium batteries, countries and regions have formulated a series of certification systems and testing standards to ensure the safety and compliance of products. This article will comprehensively analyze the certification system, testing standards and export requirements of high-voltage lithium batteries in 2026.
I. High-voltage lithium battery certification system
the certification system of high-voltage lithium batteries mainly includes international, national and regional standards and regulations. Different markets have different requirements for the safety and performance of high-voltage lithium batteries, and manufacturers need to carry out corresponding certification for the target market.
1. International Certification
international Electrotechnical Commission (IEC), International Organization for Standardization (ISO) and other institutions have formulated a series of international standards, covering the safety, performance and environmental impact of high-voltage lithium batteries. These standards provide a unified reference basis for the global market. Common international standards include:
- IEC 62133: the safety test standard for lithium batteries covers the safety test requirements of batteries such as mechanical, thermal and short circuit.
- ISO 12405: according to the performance test standard of lithium batteries in electric vehicles and energy storage equipment.
2. National certification
in the certification system of high-voltage lithium batteries, countries often formulate special regulations according to their own market demands and safety standards. For example:
- united States: The National Highway Traffic Safety Administration (NHTSA) and the American Society for materials and testing (ASTM) have formulated a series of safety standards for electric vehicles and batteries.
- Europe: The European Union Commission (CEN) and the European Electrotechnical Standardization Commission (CENELEC) have formulated safety and performance standards for lithium batteries.
3. Regional Certification
in some regions, especially the Asian market, there may be differences in the certification systems between countries and regions. For example, China's compulsory product certification (CCC) and South Korea's battery safety certification (KC) provide necessary guarantees for market access of high-voltage lithium batteries.
II. Test standards for high-voltage lithium batteries
the testing standards of high-voltage lithium batteries cover many aspects, including safety testing, performance testing and environmental testing. Manufacturers must strictly follow relevant testing standards during product design and production.
1. Security testing
safety Test is the most important part of high-voltage lithium battery certification, mainly including:
2. Performance test
the performance test is mainly used to evaluate the electrical performance of high-voltage lithium batteries under normal use conditions, including:
- capacity Test: measure the actual capacity of the battery to ensure that it meets the nominal capacity requirements.
- Internal resistance test: Evaluate the internal resistance of the battery to calculate its energy loss and efficiency.
- Cycle Life Test: simulate the charge and discharge cycle of the battery and evaluate its service life and durability.
3. Environmental testing
environmental testing mainly evaluates the performance of lithium batteries under various environmental conditions, including:
- damp heat test: test the performance of the battery under high humidity and high temperature to ensure that it will not fail due to environmental changes.
- Vibration and impact test: Evaluate the vibration and impact that the battery may suffer during transportation and use to ensure its structural integrity.
III. Export requirements
for the export of high-voltage lithium batteries, manufacturers need to follow the relevant regulations and requirements of the destination country or region to ensure that the products can enter the market smoothly.
1. Document requirements
when exporting high-voltage lithium batteries, manufacturers usually need to prepare a series of documents, including:
- product qualification certificate: relevant certificates that prove that the product meets the safety and performance standards of the target market.
- Material Safety Data Sheet (MSDS): provide safety information of battery materials, including composition, disposal and first aid measures, etc.
- Test Report: The test report issued by the third-party certification authority lists the performance and safety test results of the battery in detail.
2. Packaging and identification
- dangerous goods identification: Since lithium batteries are dangerous goods, the relevant dangerous goods identification must be clearly marked on the package.
- Transportation requirements: Follow the transportation requirements of International Air Transport Association (IATA) and International Maritime Organization (IMO) to ensure the safety of batteries during transportation.
3. Tariffs and fees
different countries have different tariff and fee policies for high-voltage lithium batteries. Manufacturers need to know the relevant policies of the target market before exporting in order to reasonably plan costs and pricing.
High pressure lithium battery the certification system, testing standards and export requirements are a complex and systematic process, involving regulations and technical requirements in many aspects. Manufacturers should fully understand and comply with relevant standards and requirements when designing and marketing products to ensure the safety, performance and compliance of products.
