Outdoor energy storage power supplies (e.g. portable power supplies, mobile power stations, etc.) must obtain CE certification when entering the EU market. This certification indicates that the product complies with the relevant EU health, safety and environmental requirements. The following is the detailed process of CE marking for outdoor energy storage power supplies and the main directives involved:

I. Determine the applicable directives

Outdoor energy storage power supplies are usually required to comply with the following EU directives:

– Low Voltage Directive (LVD 2014/35/EU): applies to electrical equipment with a voltage range between 50V and 1000V AC or 75V and 1500V DC. Ensures the electrical safety of products when used in these voltage ranges.

– EMC Directive 2014/30/EU: Ensures that products do not generate excessive electromagnetic interference (EMI) during normal use and that they can operate normally in environments where EMI is present.

– Battery Directive 2006/66/EC: deals with the environmental requirements for batteries used in products, in particular regarding their heavy metal content, recycling and disposal.

– RoHS Directive (2011/65/EU): restricts the use of certain hazardous substances such as lead, mercury and cadmium in electrical and electronic equipment.

– Machinery Directive (Machinery Directive 2006/42/EC): This directive applies if the energy storage power supply contains mechanical parts to ensure the safety of the mechanical parts.

– ErP Directive (Energy-related Products Directive 2009/125/EC): This directive applies to products with energy efficiency requirements to ensure that their energy efficiency meets EU standards.

Second, product testing

– Electrical safety test (LVD): conduct product voltage withstand test, insulation resistance test, leakage current test, etc., to ensure the safety of the product when used in the specified voltage range.

– Electromagnetic compatibility test (EMC): including conducted emission test, radiated emission test, immunity test, etc., to ensure that the product will not cause interference to other equipment and can work normally in an environment with interference.

– Mechanical safety test (if applicable): Checks whether the mechanical parts of the product comply with safety standards to prevent physical injuries.

– Battery test: Test the safety and environmental friendliness of the product’s built-in battery to ensure compliance with RoHS and the Battery Directive.

Third, the preparation of technical documents

– Technical File: This includes product design drawings, circuit diagrams, parts lists, test reports, and risk assessments. All technical documents must be kept for at least 10 years for market regulators to access.

– User Manual and Warranty Information: Provide complete instruction manuals, including the safe use of the product, maintenance guidelines, etc.

IV. Risk Assessment

– Conduct a comprehensive risk assessment, analyze the various risks that may exist in the use of the product, and develop appropriate preventive measures.

V. Signing the Declaration of Conformity (DoC)

– The manufacturer or authorized representative needs to sign the EU Declaration of Conformity (DoC) based on the test results and technical documents, stating that the product complies with all relevant EU directives.

Sixth, affix the CE marking

– After completing the above steps, the product meets the requirements of the relevant EU laws and regulations, and can be affixed with the CE marking on the product, which should be clearly visible and easy to recognize, and is usually marked on the product shell or packaging.

Seven, product registration and market launch

– Before the product into the EU market, some products may need to be registered in the EU market regulators. Confirm whether the product needs to be registered and follow the requirements.

Eight, important notes

– Certification Body Selection: Although the responsibility for CE marking lies primarily with the manufacturer, many companies will choose a third-party certification body (e.g., TÜV, SGS, Intertek, etc.) to conduct the testing to ensure compliance and provide impartial proof.

– Documentation retention: All technical documentation and declarations of conformity must be retained for at least 10 years for future inspection.

– Ongoing compliance: If product design, materials or production processes change, a new risk assessment is required and retesting and updating of the Declaration of Conformity may be necessary.

Summarize

When entering the EU market, outdoor energy storage power supplies must be CE marked to demonstrate compliance with EU health, safety and environmental requirements. Companies need to ensure that their products have passed the Low Voltage Directive, Electromagnetic Compatibility Directive, Battery Directive, RoHS Directive and other relevant tests, and sign the Declaration of Conformity before affixing the CE marking before they can be legally sold in the EU market. This process ensures product safety and market compliance.
