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

Typical Industry Example | Medical Devices

Medical applications
require higher
standards for safety,
EMC, and consistency.

Common requirements include:

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
