Lithium Battery Certification & Market Access Support
For custom lithium battery systems, certification is an integral part of design and validation ó not a final step.
LARGE aligns electrical, structural, and thermal design with target market regulations from the early stage, helping customers reduce certification risks, improve first-pass approval rates, and accelerate time-to-market.
We support certification and compliance for medical, industrial, telecom, robotics, instrumentation, petrochemical, and explosion-proof applications.
Our support includes:
- Certification-oriented battery system design
- Test planning aligned with international standards
- In-house pre-testing before formal certification
- Technicaldocumentation preparation
- Engineering support during certification testing
What Determines Lithium Battery Certification Requirements?
Lithium battery certification depends on three key factors:
Application Scenario
Equipment type, power level, and risk classification
Target Market
Country or region of sale
Regulatory Requirements
Mandatory laws and applicable standards
Different combinations lead to different certification pathways.
LARGE helps define the right certification strategy early to avoid redesign and delays.
Overview of Lithium Battery Certification Types in Major Markets
Overview of common certification types for custom lithium batteries in major markets. Final standards and validity depend on
product design, application, and target market regulations.
| Target market | Certification scheme | Mandatory or voluntary nature | Applicable standards | Certificate validity | |
|---|---|---|---|---|---|
| China Mainland | CQC |  | voluntary | GB 31241-2014 | Long-term |
| Korea | KC |  | Mandatory | KC62133 | 5 Years |
| Japan | PSE |  | Mandatory | Appendix 9 | Long-term |
| Taiwan, China | BSMI |  | Mandatory | CNS15364, CNS14336-1 | 3 Years |
| USA | UL |  | voluntary | UL1642 / UL2054 | Long-term |
| USA | FCC |  | Mandatory | Part 15B | Long-term |
| Canada | CSA |  | voluntary | UL2054 or UL60950 | Long-term |
| Europe | CE |  | Mandatory | EN 55032 / 55035, EN61000 | Long-term |
| Russia | GOST-R |  | Mandatory | IEC62133-2012 | 3 Years |
| CB | CB | / | voluntary | IEC62133-2012 | Long-term |
| Transportation | UN38.3 | / | Mandatory | ST/SG/AC.10/11/Rev.6 | Long-term |
| Global | RoHS | / | Mandatory | ||
| Note: Testing scope, sample quantity, timelines, and surveillance requirements differ by certification program and must be evaluated case by case. | |||||
Typical Industry Example | Medical Devices
Medical applications
require higher
standards for safety,
EMC, and consistency.
- IEC 62133
- IEC 60601
- Stricter EMC controls
- ISO 13485 quality system
- Enhanced traceability and consistency
LARGE integrates these requirements into system design and validation to minimize impact on overall equipment certification.
Pre-Certification Testing Support
Certification failures are often caused by insufficient system-level validation.LARGE conducts in-house testing before submission to third-party labs to identify and mitigate risks early.
- Cell- and pack-level validation
- Safety, environmental, and electrical performance testing
- Test plans aligned with global standards
- Improved first-pass certification success rate
