The Battery Passport is a digital record that tracks essential data about a battery’s lifecycle — from raw material sourcing to recycling. Think of it as a “digital twin” that provides information on carbon footprint, material origin, performance, and compliance.
Starting in 2027, the EU Batteries Regulation will mandate that all industrial and EV batteries above 2 kWh must include a digital Battery Passport accessible through a QR code. This initiative is designed to build transparency, safety, and sustainability across the global energy ecosystem. (European Commission)
At Sunlith Energy, we recognize how this change aligns with our mission to build safer, cleaner, and future-ready energy storage systems (ESS).
Why the Battery Passport Matters
1. Traceability Across the Supply Chain
The Battery Passport ensures that every stage — from mining to manufacturing, EV usage, second-life applications, and recycling — is documented. This reduces risks of unethical sourcing and improves compliance with global sustainability standards.
By 2027, all manufacturers must adopt digital passports for large batteries. This includes data on materials, carbon footprint, and recycling rates. The Battery Pass Project provides detailed guidance on the required attributes (Battery Pass Consortium).
3. Boosting Consumer Trust
Consumers and fleet operators will be able to scan a QR code and instantly view:
Carbon footprint (e.g., 65 kg CO₂ per battery)
Material origin (Lithium: Chile, Cobalt: DRC)
Recycled content (e.g., 15% of metals reused)
This transparency empowers greener purchasing decisions.
Global Efforts Driving the Battery Passport
The Global Battery Alliance (GBA) is leading the effort by developing a standardized Battery Passport Framework (GBA Battery Passport). GBA pilots are already running with automakers and energy companies to test data sharing and compliance models (GBA Pilots).
Even automakers are moving ahead — Volvo became the first to issue a digital battery passport for its EV lineup, well before the EU mandate (Reuters).
At Sunlith Energy, we’re preparing our commercial and industrial ESS to meet these requirements, ensuring compliance and customer trust.
Benefits for the Energy Storage Sector
🔹 Sustainability and Circular Economy
Battery Passports encourage second-life applications and recycling by providing accurate records of material health and usage cycles. This helps optimize ESS deployments for solar, wind, and commercial operations.
🔹 Industry Standardization
With frameworks like the DIN DKE SPEC 99100, companies gain a clear path to standardize reporting and compliance (Charged EVs).
🔹 Competitive Advantage
Companies that adopt the Battery Passport early will gain a market edge, especially in Europe, where sustainability standards are strict.
Battery Passport Implementation Timeline
2024–2025 → Pilot projects and voluntary adoption (GBA Pilot Wave)
2026 → Mandatory data collection requirements for large batteries
2027 → Battery Passport becomes legally required in the EU

Battery systems are powering everything from household electronics to advanced energy storage systems. But with the rapid adoption of rechargeable batteries, safety becomes a critical concern. That’s where UL 2054 certification comes into play.
UL 2054 is a globally recognized safety standard developed by Underwriters Laboratories (UL). It defines rigorous testing methods and requirements for household and commercial battery packs. Achieving compliance ensures that battery systems can operate safely under normal and foreseeable misuse conditions.
In this article, we’ll explore the scope, testing procedures, and importance of UL 2054 certification, and why manufacturers, integrators, and end-users should pay attention to it.
What is UL 2054 Certification?
UL 2054 is the Standard for Household and Commercial Batteries. It applies to battery packs rather than individual cells. This means it evaluates the pack as a complete unit, including protection circuits, connectors, and housing.
The goal is to ensure that batteries do not pose hazards such as:
Fire risks due to overheating or short-circuiting
Electric shock from exposed components
Explosions caused by thermal runaway
Leakage of hazardous materials
By testing for these risks, UL 2054 certification helps build trust in products used in homes, workplaces, and commercial systems.
Scope of UL 2054
The standard covers a wide range of battery chemistries and applications. Some examples include:
Lithium-ion battery packs for consumer electronics
Nickel-based rechargeable packs for power tools
Commercial battery packs in medical devices and security systems
Energy storage applications for residential backup
It applies to both primary (non-rechargeable) and secondary (rechargeable) batteries packaged as complete packs. However, it does not cover large industrial batteries or electric vehicle batteries, which fall under other standards like UL 1973 or UL 2580.
Key Testing Requirements in UL 2054
UL 2054 certification requires manufacturers to subject battery packs to strict evaluation procedures. Some of the critical tests include:
1. Electrical Tests
Short-circuit test: Ensures the battery can withstand external and internal shorts without fire or explosion.
Overcharge test: Evaluates safety when charged beyond its rated voltage.
Abnormal charge test: Simulates improper charging to check resilience.
2. Mechanical Tests
Impact test: Drops or crushes the battery to check for fire hazards.
Vibration and shock tests: Simulates transportation and handling conditions.
Mold stress test: Evaluates housing durability under heat and pressure.
3. Environmental Tests
Temperature cycling: Exposes batteries to extreme hot and cold cycles.
Humidity test: Ensures performance under moisture exposure.
Altitude test: Evaluates behavior under low-pressure environments.
4. Safety and Protection Circuit Evaluation
UL 2054 also reviews the battery management system (BMS) and protective components inside the pack, including:
Overcurrent protection
Overtemperature protection
Cell balancing mechanisms
Why UL 2054 Certification Matters
For manufacturers, UL 2054 certification provides:
Market credibility with proof of safety compliance
Regulatory acceptance in North America and beyond
Reduced liability risks from battery failures
For consumers and businesses, it guarantees:
Safe operation in everyday applications
Trust in product quality
Compliance with insurance and regulatory requirements
In industries such as medical devices, home energy storage, and consumer electronics, certification is often a prerequisite for product approval.
UL 2054 vs. Other Battery Standards
UL 2054 is sometimes confused with other UL battery standards. Here’s how it compares:
Think of UL 2054 as the bridge between cell-level and system-level safety, ensuring that battery packs are safe before they are integrated into larger applications.
For companies like Sunlith Energy, integrating UL2054-compliant packs ensures that larger systems achieve not only compliance but also customer trust.
Conclusion
UL2054 certification is a cornerstone of battery safety for household and commercial packs. By addressing risks such as fire, leakage, and mechanical damage, it ensures that batteries powering our everyday lives operate reliably and securely.
As the demand for energy storage and battery-powered devices grows, compliance with UL 2054—and related standards—will remain essential for manufacturers, integrators, and consumers alike.
If you are developing or sourcing batteries for consumer electronics, medical devices, or energy storage applications, make sure they are UL 2054 certified to guarantee safety, compliance, and long-term performance.
