What Are the Essential Industry Certifications for Rack Battery Backup Power Systems?
Why Is IEC 62619 Compliance Critical for Lithium-Ion Rack Batteries?
IEC 62619 addresses safety requirements for industrial lithium-ion batteries, focusing on operational stability, abuse tolerance, and environmental resilience. Compliance ensures systems withstand overcharging, short circuits, and extreme temperatures. This certification is mandatory for international markets, particularly in regions like the EU and Asia, where lithium-ion adoption in data centers and telecom is surging.
Modern lithium-ion rack batteries must pass IEC 62619’s stringent thermal runaway tests, which simulate worst-case scenarios like internal cell failures. For example, the standard requires batteries to maintain containment of flammable gases and prevent fire propagation for at least 60 minutes during thermal runaway events. This is critical for multi-rack installations where a single failure could cascade through adjacent units. Manufacturers achieving IEC 62619 certification often implement advanced safety features such as:
| Safety Feature | Purpose |
|---|---|
| Cell-level fusing | Isolate faulty cells |
| Gas venting channels | Redirect thermal emissions |
| Multi-layer separators | Prevent internal short circuits |
Data center operators in Singapore recently mandated IEC 62619 compliance after a 2023 incident where non-certified racks caused a facility-wide shutdown. The standard’s emphasis on design-for-failure principles makes it indispensable for critical infrastructure.
How Does CE Marking Influence Rack Battery Sales in the EU?
CE marking indicates compliance with EU health, safety, and environmental directives. For rack batteries, this includes RoHS (Restriction of Hazardous Substances) and EMC (Electromagnetic Compatibility) standards. Non-CE systems face import bans, making this certification critical for European market access.
The CE certification process requires manufacturers to document technical files demonstrating adherence to the Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility Directive (2014/30/EU). For lithium-ion rack batteries, this involves third-party testing for:
- Cadmium content below 0.01% (RoHS Annex II)
- Radiated emissions under 30 MHz (EN 55032)
- Immunity to electrostatic discharges up to 8 kV (EN 61000-4-2)
| Requirement | Testing Standard |
|---|---|
| Chemical Restrictions | EN 50581 |
| Safety Protections | EN 50604 |
| EMC Performance | EN 301 489 |
German customs authorities rejected 23% of non-CE battery shipments in Q1 2024, highlighting enforcement trends. Manufacturers must also provide EU Declaration of Conformity documents and maintain post-market surveillance systems to report field failures.

“Certifications like UL 1973 and IEC 62619 are non-negotiable for mission-critical applications,” says a Redway Power engineer. “We’ve seen clients bypass regional codes to cut costs, only to face six-figure retrofit expenses after failing fire inspections. Third-party validation isn’t just about safety—it’s financial risk mitigation.”
FAQs
- Q: Do all rack battery backups require UN/DOT 38.3 certification?
- A: Only lithium-ion systems shipped via air or sea need UN/DOT 38.3. Stationary lead-acid batteries are exempt.
- Q: Can a rack battery have UL 1973 without IEC 62619?
- A: Yes, but it limits deployment to North America. Global installations require both certifications.
- Q: Does NFPA 855 apply to residential rack battery systems?
- A: NFPA 855 applies to commercial/industrial ESS. Residential systems follow NFPA 855 only if exceeding 20 kWh.
