The IEC 62619 standard is an international safety standard titled "Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries, for use in industrial applications," published by the International Electrotechnical Commission (IEC). Specifically developed for secondary lithium batteries (including lithium-ion and lithium polymer batteries) used in industrial equipment, this standard focuses on their safety requirements. It covers all levels from individual cells to complete battery systems, providing clear technical specifications and safety assessment guidelines for energy storage battery manufacturers.

Product Scope Applicable to IEC 62619 Standard

The IEC 62619 standard primarily applies to the following types of energy storage batteries used in industrial equipment:

• Stationary Energy Storage Systems: Including UPS uninterruptible power supplies, photovoltaic energy storage systems, wind energy storage systems, and grid peak-shaving systems.

• Industrial Vehicle Power Sources: Such as for industrial handling equipment (AGVs), automated guided vehicles, and energy storage systems for railway and marine transport.

• Telecommunication Backup Power: Base station backup power, data center backup power, etc.

• Other Industrial Applications: Energy storage batteries used in medical equipment, power tools, and other industrial fields.

It is important to note that this standard does not apply to batteries for consumer electronics (such as mobile phones, laptop batteries), which are typically covered by the IEC 62133 standard.

Importance of IEC 62619 Certification

• Essential Requirement for Market Access: IEC 62619 certification is a key technical threshold for energy storage batteries entering the international market. Obtaining this certification signifies that the product complies with international safety standards, opening doors to global markets for manufacturers.

• Crucial Guarantee for Product Safety: The testing and evaluation involved in IEC 62619 certification effectively verify the safety of energy storage batteries under normal use and single fault conditions, significantly reducing risks like thermal runaway, fire, and explosion.

• Enhancing Product Competitiveness: An IEC 62619 certificate serves as authoritative proof of product quality and safety, boosting customer confidence and enhancing the product's competitive position in the market.

• Effective Means for Technical Optimization: The testing and evaluation during the certification process help manufacturers identify potential flaws in product design, providing valuable references for product optimization and technical improvement.

Detailed Explanation of Main IEC 62619 Test Items

1. Electrical Safety Tests

   • Overcharge Test: Evaluates the safety performance of the battery under overcharge conditions.

   • Over-discharge Test: Examines the safety behavior of the battery during over-discharge.

   • External Short Circuit Test: Verifies the protection functionality of the battery during an external short circuit.

   • Unbalanced Charging Test: Assesses the safety of multi-cell battery packs under unbalanced charging conditions.

2. Mechanical Safety Tests

   • Vibration Test: Simulates vibration environments during transport and use.

   • Mechanical Shock Test: Evaluates the battery's resistance to impact.

   • Crush Test: Examines the safety performance of the battery under mechanical crush.

3. Environmental Safety Tests

   • Thermal Abuse Test: Assesses the stability of the battery in high-temperature environments.

   • Temperature Cycling Test: Checks the battery's adaptability in changing temperature environments.

   • Low Pressure Test: Simulates low-pressure conditions at high altitudes.

4. Functional Safety Tests

   • Battery Management System (BMS) Evaluation: Comprehensive testing of the BMS protection functions.

   • Communication Protocol Verification: Confirms the reliability of communication between the battery and the host device.

IEC 62619 Certification Process

• Stage 1: Preparation

  • Determine product applicability and testing requirements.

  • Prepare technical documentation, including product specifications, circuit diagrams, and construction drawings.

  • Develop a detailed test plan.

• Stage 2: Sample Testing

  • Submit samples to an accredited laboratory.

  • Conduct full-item testing according to the IEC 62619 standard.

  • Record test data and analyze results.

• Stage 3: Report Review

  • Compile test data and reports.

  • Technical review by the certification body.

  • Supplementary testing if necessary.

• Stage 4: Certificate Issuance

  • Issue the IEC 62619 certificate upon successful review.

The entire certification cycle typically takes 4-6 weeks, depending on the product's complexity and test progress.
