Against the backdrop of global carbon neutrality goals, the energy storage industry has experienced explosive growth—yet safety remains a critical concern. The IEC 62619 standard, as an internationally authoritative guideline for the safety of large-scale lithium-ion battery energy storage systems, has become a core "passport" for products entering global markets. Guangdong Energy Storage Testing Technology Co., Ltd. (hereinafter referred to as "Energy Storage Testing"), with its profound technical accumulation and rigorous testing services, has emerged as a trusted partner for many leading energy storage enterprises.

Client Background: A Leading Energy Storage System Integrator

The client in this case is a well-known domestic and international provider of energy storage system solutions (referred to as "Company A" due to client confidentiality requirements). Company A specializes in large-scale containerized energy storage systems for grid-side and industrial/commercial applications. Its products are renowned for high energy density, long cycle life, and intelligent management, with business covering high-end markets in Europe, America, Asia-Pacific, and beyond. As overseas orders surged, Company A urgently needed authoritative IEC 62619 test reports for its new-generation energy storage products to meet mandatory access requirements in target markets and demonstrate the exceptional safety and reliability of its products to clients.

Challenges: High Standards, Strict Requirements, and a Tight Timeline

Company A set extremely rigorous criteria for selecting partners. Its challenges extended beyond the technical complexity of the IEC 62619 standard itself to the pressing project timeline. The new product incorporated multiple innovative designs, placing high demands on the testing institution’s ability to interpret standards professionally and respond quickly to unexpected issues. Company A sought more than just a test report—it needed a strategic technical partner capable of deeply understanding its product design, anticipating potential risks, and providing effective improvement recommendations.

After multiple rounds of evaluation, Company A ultimately chose Energy Storage Testing. What attracted them was the professional and systematic service capabilities demonstrated by Energy Storage Testing.

Solution from Guangdong Energy Storage Testing: Demonstrating Professionalism and Efficiency

To address Company A’s needs, Guangdong Energy Storage Testing quickly established a dedicated project team consisting of senior engineers, offering one-stop services from pre-evaluation and formal testing to report review.

1. Precise Pre-Evaluation and Gap Analysis

At the start of the project, instead of rushing into formal testing, Energy Storage Testing’s engineering team conducted multiple in-depth technical discussions with Company A’s R&D team. Based on a thorough understanding of the IEC 62619 standard, they performed a comprehensive "pre-scan" of Company A’s product—covering its Battery Management System (BMS) strategy, electrical structure, mechanical structure, and material selection—to identify several potential risk points that might not comply with the standard. This detailed gap analysis report helped Company A gain valuable time for targeted design optimizations, avoiding potential failure risks during formal testing.

2. Rigorous and Efficient Formal Testing Execution

The IEC 62619 standard encompasses multiple levels of testing (cell testing, battery module/system testing) and covers diverse dimensions including electrical safety, mechanical safety, environmental safety, and functional safety. Leveraging its advanced laboratories accredited by CNAS and CMA, Energy Storage Testing conducted key safety tests on Company A’s product in strict accordance with standard procedures—including overcharge, external short circuit, thermal abuse, drop, and crush tests. Throughout the testing process, the engineering team demonstrated high professional competence; real-time monitoring and analysis of test data ensured the accuracy and traceability of results.

Outcomes and Value: In-Depth Cooperation Beyond a Test Report

Through close collaboration between the two teams, Company A’s new-generation energy storage system successfully passed all IEC 62619 test items and quickly obtained an authoritative test report. This achievement removed the most critical technical barrier to the product’s global market entry and strongly supported the signing of several important overseas orders for Company A.

For Company A, the value of this cooperation exceeded expectations:

• Market Access Guarantee: Obtained an internationally recognized "passport," enhancing the brand’s competitiveness in global markets.
• Product Safety Enhancement: The pre-evaluation and problem-solving during testing led to substantial optimizations in the product’s safety design.
• R&D Efficiency Improvement: The professional services of Energy Storage Testing shortened the product certification cycle and accelerated its time-to-market.

Conclusion

Serving leading enterprises is in itself a recognition of a testing institution’s comprehensive capabilities. Through this successful cooperation with Company A, Guangdong Energy Storage Testing Technology Co., Ltd. has once again verified its technical strength and service standards in the energy storage testing field. We understand that behind every test report lies the client’s product reputation and market prospects. We will continue to uphold the quality policy of "Science, Impartiality, Accuracy, Efficiency," and use solid technical capabilities, rigorous work attitudes, and proactive collaboration to support more energy storage enterprises in expanding globally—jointly promoting the steady development of the energy storage industry on a safe foundation.
