Editor:ESTL Category:Certification information Release time:2025-09-22 Click volume:5
I. Standard Overview
IEC 62619 is an international safety standard for industrial lithium batteries and systems, ensuring safety during production, transportation, and use. It addresses risks associated with high-energy-density batteries through strict design requirements and verification testing.
Scope:
- Industrial energy storage systems
- Telecom base station backup power
- Industrial vehicle power systems
- Other industrial applications
Exclusions:
- Consumer electronics batteries (covered by IEC 62133)
- Road vehicle batteries (covered by IEC 62660 series)
II. Key 2022 Updates
- New EMC requirements: Enhanced electromagnetic compatibility testing
- Strengthened BMS: Improved battery management system safety
- Updated thermal runaway testing: More scientific methodology
- Enhanced safety information: Detailed marking and user manual requirements
III. Core Safety Design Requirements
1. Basic Operating Parameters
- Temperature range: -20°C to 60°C
- Charging limit: Cell voltage ≤ 3.6V
- Storage recommendation: SOC maintained at 30%-50%
2. Safety Protection Design
- Physical protection: Impact-resistant, leak-proof enclosure
- Electrical protection: Overcurrent, overvoltage, overtemperature protection
- Chemical protection: Anti-leakage and gas accumulation prevention
- Pressure relief: Safety venting for excessive internal pressure
3. Battery Management System (BMS)
Monitoring functions:
- Cell voltage monitoring (2.0V-3.6V range)
- Charge/discharge current monitoring
- Real-time temperature detection
- Battery state (SOC/SOH) evaluation
Protection mechanisms:
- Overcharge protection
- Overdischarge protection
- Overcurrent protection
- Overtemperature protection
- System fault locking
IV. Key Test Items
- Internal short circuit test: Simulates cell defects
- External short circuit test: Shorts terminals through low-resistance wire
- Thermal abuse test: Heats battery to 130°C for 30 minutes
- Overcharge test: Charges at 1.2× rated voltage
- Other important tests:
- Crush test: Verifies mechanical strength
- Drop test: Simulates accidental impacts
- Forced discharge test: Evaluates reverse polarity safety
V. Marking and Documentation
Product markings must include:
- Manufacturer information
- Model and specifications
- Rated voltage/capacity/energy
- Production date
- Certification marks
Warning labels should indicate:
- High voltage warning
- Prohibited actions (short circuit, disassembly)
- Temperature range limitations
- Professional operation requirements
User documentation must cover:
- Installation and wiring instructions
- Safe operating parameters
- Maintenance procedures
- Emergency handling
- Disposal guidelines
VI. Relationship with Other Standards
- IEC 62133: Consumer portable device batteries
- IEC 62620: Industrial lithium battery performance
- UN38.3: Transportation safety requirements
Industrial lithium battery projects typically need to meet both IEC 62619 (usage safety) and UN38.3 (transport safety) requirements.
VII. Compliance Recommendations
- Design phase: Incorporate safety requirements early
- Testing: Select qualified laboratories for full testing
- Production: Establish quality control for consistency
- Documentation: Maintain complete technical files
- Continuous improvement: Follow standard updates and best practices
