Overview
EN 50604-1:2016/A2:2025 is a crucial amendment to the European standard that governs secondary lithium batteries specifically designed for light electric vehicle (EV) applications. Issued by CLC and scheduled for mandatory national implementation by June 2026, this update offers enhanced clarity and precision to the general safety requirements and test methods originally set forth in EN 50604-1:2016. The amendment addresses important questions raised by test institutes, facilitating more consistent and reliable battery safety testing practices throughout the industry.
Key Topics
- General Safety Requirements: The amendment reinforces the foundational safety protocols for lithium secondary batteries used in light EVs, ensuring robust protection during all operational conditions.
- Test Method Clarifications: It elaborates on test procedures, including modifications to test conditions and sample requirements, to eliminate ambiguity and improve reproducibility of results.
- Tolerance Specifications: Detailed accuracy tolerances for measurements during testing are provided, such as:
- Voltage, current, and capacity within ±1%
- Temperature tolerance within ±2 K (with an additional ±5 K under specific test conditions)
- Time and dimensions within ±0.1%
- Mechanical frequencies within ±2%
- Crush Test Adjustments: The amendment states that if a battery system is secured by double mechanical protection (such as a latch combined with a rigid cover or frame), a crush test is not mandatory. Additionally, the number of samples required for crush testing is explicitly set to two - one per direction tested.
- Alignment with Other Standards: EN 50604-1:2016/A2:2025 is intended to be used alongside ISO 12405 series and ISO 6469-1:2019 documents, enhancing harmonization across industry practices.
Applications
- Light Electric Vehicles: This standard is tailored for lithium batteries powering lightweight EVs such as e-bikes, electric scooters, and small electric cars, where safety and reliable testing are paramount.
- Battery Manufacturers and Test Laboratories: Battery producers, testing institutes, and quality assurance organizations use this standard to ensure their products meet rigorous European safety requirements.
- Regulatory Compliance: Helps manufacturers comply with European regulations by providing clear testing frameworks, measurement tolerances, and definitions to support certification and market access.
- Design and Engineering: Engineers can reference this standard to design battery systems that meet double mechanical protection requirements, potentially eliminating the need for certain destructive tests, thus optimizing development costs and timelines.
Related Standards
- EN 50604-1:2016 (Original Version): The base document on secondary lithium battery safety and testing for light EVs that this amendment updates.
- ISO 12405 Series: Covering lithium-ion battery testing methods, closely related to the scope of EN 50604-1 for secondary cells.
- ISO 6469-1:2019: Specifies safety requirements for electric road vehicles, providing complementary safety guidelines relevant to battery systems.
- CENELEC and National Standards: This amendment must be adopted as a national standard by all CENELEC members, impacting safety regulations across European countries including Germany, France, Italy, Spain, and the UK.
Maximize your lithium battery safety compliance by adopting EN 50604-1:2016/A2:2025, ensuring accuracy in testing and leveraging updated safety protocols for light electric vehicle applications. This standardized approach supports the development of reliable, safe, and market-ready lithium secondary batteries in Europe and beyond.
