As demand for outdoor activities and emergency backup power grows rapidly, outdoor energy storage power supplies—reliable independent energy solutions—are quickly entering global markets. Faced with diverse certification requirements across countries, CB certification stands out as the preferred choice for outdoor energy storage power supply manufacturers to unlock international markets, thanks to its unique advantage of "one test, globally recognized". This article comprehensively explains the key points, processes, and value of CB certification for outdoor energy storage power supplies.

What Is CB Certification? Why Is It Crucial for Outdoor Energy Storage Power Supplies?

The CB Scheme is a global mutual recognition system established by the IEC System of Conformity Assessment Schemes for Electrotechnical Equipment and Components (IECEE). Its core value lies in obtaining globally recognized reports and certificates through a single test. For outdoor energy storage power supplies, this means:

• Reduced Repeat Testing Costs: Avoid multiple tests when entering different national markets, significantly saving time and money.
• Accelerated Market Launch: Convert CB certificates and reports into local certifications, greatly shortening the product launch cycle.
• Enhanced Product Competitiveness: CB certification is a strong proof that products meet international standards, boosting buyer confidence.

Core Standards for CB Certification of Outdoor Energy Storage Power Supplies

Outdoor energy storage power supplies are comprehensive products, typically involving multiple CB certification standards:

1. Whole Machine Safety Standards

• IEC 62368-1: Safety Requirements for Audio/Video, Information and Communication Technology Equipment
• IEC 62040-1: Safety Requirements for Uninterruptible Power Supply (UPS) Systems

2. Battery Safety Standards

• IEC 62619: Safety Requirements for Secondary Lithium-Ion Cells and Batteries for Industrial Use
• IEC 62133-2: Safety Requirements for Portable Sealed Secondary Lithium-Ion Cells and Batteries
• IEC 63056: Safety Requirements for Secondary Lithium-Ion Cells and Batteries for Electrical Energy Storage Systems

3. Key Considerations

According to the latest IECEE regulations, for mobile energy storage systems with UPS functions that involve multiple product categories (e.g., ITAV and OFF), test reports from multiple standards may need to be integrated. Ultimately, a single CB certificate covering multiple standards will be issued.

Detailed CB Certification Process

CB certification for outdoor energy storage power supplies usually includes the following key phases:

Phase 1: Preparations (1-5 Working Days)

• Confirm product standards: Clarify the IEC safety standards applicable to the product.
• Select an NCB: Choose a national certification body recognized by IECEE.
• Prepare technical documents: Include product manuals, circuit diagrams, lists of key components, etc.

Phase 2: Sample Testing (2-4 Weeks, Core Phase)

• Send samples: Deliver samples as required by the NCB.
• Laboratory testing: Conduct safety tests in accordance with IEC standards by a CB Testing Laboratory (CBTL).
• Test items: Include electrical insulation, protection against electric shock, temperature rise, abnormal operation testing, battery overcharge/overdischarge protection, short-circuit testing, etc.

Phase 3: Review & Certificate Issuance (1-2 Weeks)

• Report review: The NCB reviews the test report issued by the CBTL.
• Certificate issuance: After passing the review, the NCB issues the CB Test Certificate and Report.
