IEC 62620 is the international standard specifically addressing performance requirements for industrial secondary lithium-ion cells and batteries. It specifies marking, testing, and requirements for lithium secondary batteries used in industrial applications.
| Certification Aspect | Details | Notes/Requirements |
|---|---|---|
| Standard Name | IEC 62620: Secondary cells and batteries containing alkaline or other non-acidic electrolytes – Secondary lithium cells and batteries for industrial applications | Latest version: IEC 62620:2014+AMD1:2023 CSV |
| Scope | Industrial secondary lithium cells and batteries (with alkaline or other non-acidic electrolytes) | Not applicable to road vehicles (e.g., electric cars) |
| Applications | • Fixed: Telecom equipment, UPS, energy storage systems, grid switching, emergency power • Mobile: Forklifts, golf carts, AGVs, railway and marine transport (non-road vehicles) |
Covers stationary and mobile industrial uses |
| Core Tests | • Discharge performance (ambient and low temperature) • High-rate current capability • Charge retention and recovery • Internal resistance (AC/DC) • Cycle life • Storage life |
• Low temp discharge ≥70% rated capacity • High-rate test: no melting/deformation, ≥95% capacity • Charge retention ≥85%, recovery ≥90% • Internal resistance ≤ manufacturer's value • ≥60% capacity after 500 cycles • ≥85% capacity after 90 days storage |
| Certification Process | 1. Application & documentation 2. Sample submission 3. Product 整改 (if needed) 4. Test report 5. Report evaluation 6. Certificate issuance |
Timeline varies by product complexity |
| Certificate Value | Proof of compliance with international standards, enhances competitiveness, supports market access, may be required for government subsidies (e.g., Queensland, Australia) | Recognized globally for industrial applications |

Consider these factors when choosing your testing partner:
Q1: What's the difference between IEC 62620 and IEC 62619?
A1: IEC 62620 focuses on performance requirements (capacity, resistance, cycle life), while IEC 62619 emphasizes safety aspects (electrical, mechanical, thermal abuse) and includes BMS functional safety assessment. They complement each other for comprehensive evaluation.
Q2: What are the benefits of IEC 62620 certification?
A2: Certification demonstrates compliance with international performance standards, enhances market competitiveness, facilitates global market access, and may be required for government incentives (e.g., Queensland, Australia).
Q3: How long does certification take and what's the cost?
A3: Timeline and cost vary significantly based on battery type, required tests, need for Rectification，and chosen certification body. Contact testing laboratories directly for customized quotes.
Q4: What happens if testing fails?
A4: The laboratory will provide detailed Rectification recommendations. You'll need to modify product design, materials, or processes accordingly and resubmit samples for re-testing until all requirements are met.
Would you like me to create a comparison chart between IEC 62620 and IEC 62619 to help stakeholders understand their complementary nature? Or perhaps you need guidance on specific test preparation for your products?
