Compliance Support for Battery Charger Projects
Compliance is not a single logo that can be applied to every charger. A charger supplied to a vehicle manufacturer, battery brand, importer, wholesaler, or equipment supplier may require different documentation depending on its electrical design, battery system, market, and use case.
Before order approval, Linjia recommends confirming the exact charger model, input and output specification, target country or region, required standard, and certification documents. This helps reduce the risk of using a certificate outside its applicable scope.

ISO 9001 Quality Management System Certificate
This ISO 9001 Quality Management System Certificate demonstrates Linjia’s commitment to standardized manufacturing, quality control, and continuous improvement throughout battery charger production.
Product Compliance for Different Markets
A charger intended for a new market should be reviewed as a complete project. Linjia can evaluate the charger configuration together with the customer’s battery specifications, BMS requirements, local AC input, plug type, connector, cable configuration, operating environment, and requested compliance documentation.
This is especially important for OEM/ODM projects because changes to voltage, charging current, charging profile, housing, cable, connector, or other project specifications may affect which test or certification documentation is applicable.
- • Target market and destination country or region
- • Battery type, nominal voltage, full‑charge voltage and BMS requirements
- • Local AC input voltage, frequency and plug type
- • Output connector, cable and polarity / pin definition
- • Required certificate, test report or customer compliance checklist
ISO 9001 Quality Management System
Linjia operates under an ISO 9001 quality management system and uses standardized manufacturing and inspection procedures to support consistent charger production. Quality control is connected to the manufacturing process rather than treated as a final paperwork step.
The current quality process includes:
- • Incoming material inspection
- • PCB and semi‑finished product testing
- • Finished‑product electrical performance testing
- • High‑voltage insulation testing
- • Full‑load burn‑in testing
- • Final order, label, connector and packaging verification according to project requirements
For buyers, the value of ISO 9001 is not the logo alone. The practical value is a more controlled path from approved specification and sample to repeated batch production.
Project‑Specific Compliance Review
For customized battery charger projects, compliance should be reviewed before sampling or mass production. Linjia can use the target‑market requirement as part of the engineering review so the charger specification and required documentation are considered together.
Recommended information to send:
- • Battery type and battery specification
- • Nominal voltage and full‑charge voltage, if available
- • Battery capacity and desired charging current
- • BMS requirements, if applicable
- • Connector photo, pin definition or polarity requirement
- • Local input voltage and plug type
- • Application and operating environment
- • Destination market and required certification / standard
- • Estimated order quantity
Our Ongoing Commitment
Certifications and compliance documents are one part of a reliable charger supply program. Linjia continues to improve its engineering review, manufacturing process, testing methods, and project control so that the charger delivered to the buyer remains aligned with the approved technical requirements.
For every export or OEM/ODM project, the correct approach is to verify the applicable certificate and test documentation for the exact charger model and destination market before shipment—not to rely on a generic certification claim.
We're Here to Answer All Your Questions
What certifications does Linjia currently have?
Linjia has obtained ISO 9001 quality management system certification. Relevant charger models can also be supported by CE certification and applicable IEC testing documentation depending on the model and target‑market requirements.
Are all Linjia battery chargers CE certified?
Certification scope must be confirmed for the exact model. This page should not imply that every charger model has identical certification coverage. Please send the model or battery requirements and destination market for project‑specific confirmation.
Can you support certification or testing required by our market?
Linjia can review the requested standard or documentation as part of the project evaluation. Feasibility and the applicable report or certificate depend on the charger design, selected model, destination market, and exact compliance requirement.
What information should we provide for a compliance review?
Please provide the battery type, voltage, capacity, charging current, BMS requirement, connector, local AC input, plug type, application, target market, required standard or certification, and expected quantity.
Can compliance documents be confirmed before mass production?
Yes. For OEM/ODM projects, the recommended approach is to confirm the charger specification and required compliance documentation before production approval. Any specification change that may affect applicability should be reviewed again.
