The Essential Role of a BMS in Energy Storage Systems
22,Nov 2025
If you’re dealing with industrial lithium-ion batteries, especially for applications like forklifts, UPS systems, or energy storage, understanding IEC 62619 is key. This standard focuses on the safety and reliability of secondary lithium cells and batteries, ensuring they perform safely under real-world conditions.
IEC 62619 is a global safety standard designed for secondary lithium-ion batteries used in industrial and motive power applications. It replaces older specs by providing updated testing methods that reflect modern battery technologies and real-use scenarios.
Here’s a quick look at the primary safety areas the standard covers:
| Core Safety Area | What It Means |
|---|---|
| Thermal Stability | Tests to prevent thermal runaway |
| Mechanical Abuse Testing | Impact, crush, and vibration |
| Electrical Abuse Testing | Overcharge, short-circuit control |
| Environmental Stress | Exposure to moisture, temperature |
| Cell Aging and Cycle Life | Ensures durability over time |
These requirements aim to mitigate risks like battery fires, explosions, and chemical leaks, making IEC 62619 a cornerstone for lithium-ion battery safety standards worldwide.
The IEC 62619 standard has evolved to keep pace with rapid advances in lithium battery tech:
Early standards focused mostly on small consumer cells.
The industry shift to industrial-scale batteries required tougher, more comprehensive tests.
New revisions include stricter thermal runaway prevention and battery management system (BMS) integration requirements.
Enhanced alignment with transport regulations such as UN38.3.
This evolution reflects real-world feedback and incidents, shaping a certification process that prioritizes user safety and system reliability.
Understanding these fundamentals is crucial for manufacturers, buyers, and users aiming for global lithium battery safety certification and compliance in critical sectors.
Getting IEC 62619 certification means making sure your lithium-ion batteries meet strict safety standards for industrial use. Here’s a simple walk-through of the certification process:
Start by familiarizing yourself with the IEC 62619 standard. It covers safety requirements for secondary lithium cells and batteries, focusing on preventing thermal runaway and other hazards.
Test your batteries against specific IEC 62619 testing requirements. This includes mechanical, electrical, and environmental tests to check robustness and safety under different conditions.
Gather and prepare technical files, like design specs, test reports, and risk assessments. This makes the review process smoother and shows clear compliance.
Choose an accredited testing lab or certification agency familiar with industrial battery certification processes. Their expertise helps verify your product meets global lithium battery safety certification norms.
Your batteries will undergo detailed testing, including battery management system integration checks and safety performance during simulated real-world use.
If any issues come up during testing, work to fix them and resubmit your documentation. This might include design tweaks or more rigorous testing.
Once your product meets all IEC 62619 criteria, you’ll receive certification. This not only proves your battery safety but also supports regulatory requirements for UPS lithium battery regulations, forklift battery safety standards, and more.
Following these steps closely makes the path to IEC 62619 certification clear and manageable, helping you stay competitive and compliant in the U.S. industrial battery market.
When it comes to lithium-ion battery safety standards, IEC 62619 stands out because it focuses on secondary lithium cells and batteries used in industrial applications like forklifts, energy storage systems, and UPS lithium battery setups. But how does it compare to others?
UL standards, such as UL 1973 or UL 2054, are widely used in the U.S., emphasizing safety and performance for batteries in various environments. While UL is more familiar to American buyers, IEC 62619 offers a globally recognized framework, often accepted under the CB Scheme for international compliance.
UN38.3 handles the transport safety of lithium batteries, making sure they can be shipped without risks, but it doesn't cover operational safety. IEC 62619 goes deeper by testing batteries for thermal runaway prevention, electric faults, and mechanical abuse risks in real-world use.
Why Choose IEC 62619?
It’s tailored for industrial motive power batteries, focusing on long-term safety and durability.
Meets strict thermal and electrical testing requirements to lower failure risks.
Supports global lithium battery export compliance, which is crucial if your business ships batteries internationally.
Understanding the differences helps you pick the right certifications for your safety and legal needs. In the U.S. market, blending IEC 62619 with UL certifications can give you a competitive edge and smoother access to global customers.
IEC 62619 certification does more than check a box—it gives your battery products a real boost in the U.S. market and beyond. Here’s how this certification benefits manufacturers and buyers alike:
| Benefit | Why It Matters |

With IEC 62619 certification, your products don’t just comply—they earn a seal of reliability and quality. This helps build stronger partnerships and improves brand reputation in a crowded market where safety and performance are key.
IEC 62619 certification plays a big role in many industries where lithium-ion batteries are a core part of the game. From forklifts and industrial motive power batteries to UPS (uninterruptible power supply) systems, companies rely on this standard to keep things safe and efficient.
In warehouses across the U.S., forklifts powered by IEC 62619-certified batteries meet strict forklift battery safety standards, reducing risks like thermal runaway and overheating. Meanwhile, energy storage systems that need to comply with rigorous industrial battery certification processes use IEC 62619 to prove their batteries meet high safety and performance bars.
Even in backup power solutions like UPS lithium battery setups, IEC 62619 ensures that these critical systems operate reliably during power outages, keeping data centers and hospitals running smoothly. The certification also supports U.S. businesses exporting lithium batteries by aligning products with global lithium battery safety certification norms, easing compliance with international shipping rules.
In short, if you’re in the market for batteries in any heavy-duty or safety-sensitive application, IEC 62619 certification signals a reliable, tested product that meets top-tier safety standards. It’s a practical choice to protect assets, workers, and your overall operation.
