In the field of industrial energy storage and power batteries, an authoritative IEC 62619 test report is not only technical proof of product safety but also the core pass to enter global high-end markets. As global demand for stationary energy storage and industrial battery systems surges, the IEC 62619 standard has become an internationally recognized benchmark for evaluating safety and reliability.

This article will deeply analyze which batteries require an IEC 62619 report, key application scenarios of the report, core test items, and the complete process to efficiently obtain the report.

01 Applicable Product Scope: Which Batteries Need an IEC 62619 Report?

IEC 62619, fully titled Secondary cells and batteries containing alkaline or other non-acid electrolytes — Safety requirements for secondary lithium cells and batteries for industrial applications, primarily applies to non-portable lithium battery systems used in stationary or industrial environments.

Specifically, the following three categories of battery products must include IEC 62619 testing and certification in their compliance plans:

1. Stationary Energy Storage Battery Systems

• User-Side Energy Storage: Residential energy storage systems, commercial building energy storage systems.
• Grid-Side Energy Storage: Battery modules and systems in large-scale energy storage power stations for grid peak shaving, frequency regulation, and renewable energy grid integration.
• Communication & UPS Backup Power: Lithium battery packs in telecom base stations and data center uninterruptible power supplies.

2. Industrial Power & Backup Batteries

• Industrial Vehicle Power Batteries: Power battery packs for electric forklifts, automated guided vehicles (AGVs), rail vehicles, etc.
• Professional Equipment Power Supplies: Batteries for equipment in special industrial environments such as marine operations, mining, and medical applications.

3. Other Large-Scale or High-Power Battery Systems

Batteries exceeding the size and capacity limits specified in IEC 62133 (portable battery standard) and used in specific industrial scenarios.

02 Core Application Scenarios: Why Is This Report Critical?

Obtaining an authoritative IEC 62619 test report delivers value far beyond passing tests—it plays a decisive role in the following key links:

03 In-Depth Analysis of Test Items: From Electrical Safety to Functional Safety

The IEC 62619 test system goes beyond traditional single-fault safety, constructing a three-dimensional safety network covering electrical, mechanical, environmental, and system functional aspects.

1. Electrical Safety Testing

The first line of defense against electrical abuse, with core items including:

• Overcharge Test: Evaluates the effectiveness of BMS overcharge protection to prevent thermal runaway caused by uncontrolled charging.
• External Short Circuit Test: Verifies whether the protection circuit can act promptly to contain hazards during extreme short circuits.
• Abnormal Charging Test: Simulates abnormal charging conditions (e.g., charger failure) to test the battery’s tolerance and protection capabilities.

2. Mechanical & Environmental Safety Testing

Simulates reliability during transportation, installation, and harsh environments, including:

• Crush & Mechanical Shock Tests: Assesses structural integrity and safety when the battery is subjected to physical impact.
• Thermal Abuse & Temperature Cycling Tests: Examines stability and thermal propagation resistance under extreme high/low temperatures and rapid temperature changes.
• External Fire Test (Optional but Critical): Simulates battery exposure to external fire, an advanced test for evaluating fire safety.

3. Functional Safety Assessment (Top Priority)

The essence that distinguishes IEC 62619 from consumer battery standards, requiring the BMS to have active risk prevention capabilities:

• BMS Functional Safety Verification: Evaluates the reliability and response speed of the BMS in voltage/current/temperature monitoring and protection logic (e.g., disconnection, alarms) in accordance with standard requirements.
• System Safety Design Assessment: Reviews the rationality and effectiveness of engineering designs for the entire battery system, such as thermal propagation prevention, insulation protection, and ventilation design.

04 Efficient Application Process: How to Obtain an Authoritative Report Quickly?

Faced with complex and rigorous testing, a professional, efficient process is key to project success. Following these steps ensures a smooth, controllable certification journey:

Step 1: Pre-Consultation & Product Definition

Contact a professional testing institution with CBTL qualification (e.g., Guangdong Energy Storage Testing Technology Co., Ltd.) to confirm if your product is applicable to IEC 62619 and define the test scope and series classification.

Step 2: Technical Pre-Evaluation & Gap Analysis (Highly Recommended)

Before formal sample submission, have an expert team review your technical documents (BOM, circuit diagrams, BMS specifications, structural drawings) and conduct pre-testing. This step identifies and resolves over 90% of potential failure risks in advance, avoiding costly delays from formal test failures.

Step 3: Formal Testing & Full-Process Transparent Follow-Up

Conduct a full set of standard tests in a professional laboratory. Leading service providers offer an online client system, allowing you to real-time monitor test progress, raw data, and preliminary results—ensuring complete transparency.

Step 4: Report Compilation & CB Certificate Issuance

After passing tests, the laboratory issues a detailed IEC 62619 test report. For CB certification applications, you can directly obtain a CB test report and certificate issued by an NCB, which is globally recognized.

Step 5: Post-Support & Certificate Maintenance

After obtaining the report and certificate, professional institutions should provide ongoing support such as factory inspection guidance, technical document maintenance, and annual certificate reviews to ensure long-term validity.

05 Advantages of Choosing a Professional Partner

Faced with a systematic project like IEC 62619, partnering with a provider like Guangdong Energy Storage Testing Technology Co., Ltd. means you gain:

• One-Time Pass Rate: Leverages in-depth pre-evaluation and rich practical experience to significantly improve the one-time pass rate of formal tests, saving at least 30% of time costs.

• Lifecycle Services: Provides end-to-end technical support from pre-design and certification to post-factory inspections and standard updates.

Regulatory Trends & Urgency

As global energy storage market safety regulations tighten comprehensively, IEC 62619 has evolved from a "bonus" to a "must-have access ticket." Statistics show that since 2023, energy storage battery products without IEC 62619 or equivalent certifications have a nearly 100% elimination rate in bidding for large-scale European and American projects.

Meanwhile, the International Maritime Organization (IMO) and fire regulations in multiple countries have explicitly referenced or adopted IEC 62619 as the technical basis for evaluating battery safety. Early deployment is not only market-driven but also an inevitable choice for risk prevention.

06 Frequently Asked Questions (FAQs)

Q: What is the relationship between an IEC 62619 report and CB certification?

A: IEC 62619 is an international safety standard, while the CB Scheme is a globally mutual recognition certification system. Testing can be conducted based on the IEC 62619 standard to issue a CB test report, ultimately obtaining a CB certificate. This CB document is an authoritative, globally accepted proof that the product meets IEC 62619 requirements, serving as the most convenient "passport" for applying for local certifications in various countries (e.g., South Korea’s KC, Australia’s RCM).

Q: If I already have a UN38.3 test report, do I still need IEC 62619?

A: Yes, it is mandatory. UN38.3 only addresses lithium battery transportation safety, a prerequisite for shipping. In contrast, IEC 62619 evaluates the long-term operational safety of batteries in their final usage scenarios—their purposes and scopes are completely different. A product typically needs to pass UN38.3 for transportation compliance first, then IEC 62619 for operational safety.

Q: What if an item fails the test?

A: Professional institutions monitor data in real-time during testing. If a failure is detected, testing will be paused immediately to communicate with your technical team, analyze the root cause, and provide clear rectification directions. After rectification, only the failed item and related projects need to be retested (not the entire suite), saving time and costs.

Q: What is the typical cycle and cost for full certification?

A: The cycle is usually 8-12 weeks, depending on product complexity, the number of rectifications, and laboratory scheduling. Costs include testing fees, report fees, and certification service fees, varying based on battery capacity, voltage, system complexity, and the number of test items. Choosing an institution that offers pre-evaluation services helps effectively control total costs and project timelines from the start, avoiding uncontrollable expenses from repeated failures.
