1. Introduction to CE Certification

CE (Conformité Européenne) is a mandatory compliance marking for products accessing the European Economic Area (EEA). All products falling under relevant EU directives must bear the CE mark to prove compliance with EU fundamental safety, health and environmental protection requirements.

Portable energy storage power stations including outdoor power supplies, camping power stations and household backup power involve multiple overlapping EU directives. Different from single-directive compliance for common consumer goods, such products integrate lithium-ion batteries, power conversion circuits and electromagnetic components, requiring multi-dimensional compliance verification.

2. EU Directives & Standards for Portable Energy Storage Products

1. LVD Directive 2014/35/EU (Low Voltage Directive)Applicable to electrical equipment operating within 50–1000V AC or 75–1500V DC. The battery pack voltage of energy storage stations falls within this scope, complying with electrical safety requirements.Applicable Standard: EN 62619:2022, identical to IEC 62619:2022 for industrial lithium-ion batteries.

2. EMC Directive 2014/30/EU (Electromagnetic Compatibility Directive)Products shall operate stably in electromagnetic environments without causing interference to other devices. Inverters, charging circuits and control modules need to pass EMC tests.

3. Battery Directive 2006/66/ECSets concentration limits on restricted substances including mercury, cadmium and lead. Mandates waste battery recycling rules and product marking obligations.

3. Core Test Items of EN 62619:2022

1. External Short Circuit Test: Direct short-circuit on battery terminals under standard ambient temperature; no fire or explosion allowed.
2. Overcharge Protection Test: Charge with excessive voltage to verify BMS overcharge detection and cut-off performance.
3. Over-discharge Protection Test: Simulate deep discharge to validate undervoltage protection functions.
4. Overcurrent Protection Test: Apply overload current to confirm effective disconnection of protective components.
5. Drop Test: Free fall from specified height (normally 1m) to assess structural integrity.
6. Thermal Abuse Test: Expose batteries to temperature above 130℃ to evaluate thermal stability limits.
7. Compression Test: Apply standard pressure until cell deformation to check safety performance under physical abuse.
8. Temperature Cycling Test: Cycle temperature between -20℃ and +60℃ to verify structural stability against thermal stress.

4. CE Certification Application Process

1. Confirm Applicable Directives & StandardsDetermine applicable rules based on voltage, power rating and wireless functions, sort out harmonized standards such as EN 62619:2022 and EN 55032.

2. Prepare Technical DocumentsCollect product specifications, circuit diagrams, BOM, risk assessment reports and label drafts. Compile user manuals with official local language versions.

3. Conduct LVD Safety & EMC TestsComplete safety and electromagnetic compatibility tests. EN 62619 battery safety test serves as core evaluation content.

4. Compile Documents & Issue Declaration of ConformityGather all test reports and technical files. Manufacturers or authorized representatives sign the EU Declaration of Conformity.

5. Affix CE MarkPrint standard CE marks on products and packages for legal circulation in EU markets.

CE allows manufacturer self-declaration without mandatory third-party certification. Technical documents shall be retained for no less than 10 years for official inspection. Most enterprises choose qualified third-party labs to minimize compliance risks.

5. Frequently Asked Questions

Q1: Is CE certification mandatory for portable energy storage stations?A1: Yes. CE marking is compulsory for products sold in EU territories. Goods without valid CE marks will be rejected by customs and banned from market sales.

Q2: Can existing IEC 62619:2022 CB report replace CE certification?A2: CB and CE belong to independent systems and cannot substitute each other. Since EN 62619 and IEC 62619 share identical technical requirements, most CB test data can be reused to reduce CE testing scope. Additional EMC tests exclusive to CE are still required.

Q3: How long does CE certification take?A3: General testing cycle lasts 4 to 8 weeks, varying by product complexity, test items and laboratory schedule. Remedial tests for non-conformity will extend the whole period. Sufficient preparation time is recommended.

Q4: Is there no physical CE certificate?A4: The core CE credential is manufacturer-signed EU Declaration of Conformity. LVD and EMC test reports issued by labs form complete compliance evidence, which shall be presented together during official checks.

Q5: Is Battery Directive compliance still required for EU export?A5: Yes. Built-in batteries must meet hazardous substance limits of 2006/66/EC. Products shall bear crossed-out wheeled bin recycling marks and complete WEEE registration in sales countries. Battery compliance assessment shall be integrated into CE procedures.
