CE Certified Sodium-Ion Battery Modules: What EN 61000 Compliance Means for Your EU Project

Certification update - In August 2026, Issued EMC certificate No. HTT202608380E to Henan Zhuowei New Energy Technology Co., Ltd. (ZVEPOW), covering twelve 48V sodium-ion battery modules. The certificate confirms that the ZVEPOW 48V series meets the electromagnetic compatibility (EMC) requirements of EU Directive 2014/30/EU through EN IEC 61000 series emission and immunity testing.

Why CE Certification Matters for Battery Modules in the EU

Electromagnetic compatibility is not a formality for energy storage equipment - it is a market requirement. Within the EU, electrical equipment must satisfy the essential requirements of the EMC Directive 2014/30/EU before it can be placed on the market with a CE mark. For a battery module, that means two things: it must not disturb other equipment (emission), and it must keep performing correctly when exposed to electromagnetic disturbance (immunity).

For European importers, system integrators and C&I battery buyers, a module with lab-verified EMC compliance de-risks project schedules: fewer commissioning surprises, simpler documentation for EU battery regulation compliance, and a stronger due-diligence file for end customers. Our safety certification guide walks through the full picture of CE, UN38.3 and MSDS.

Certificate at a Glance: 12 Models, One Compliance File

The certificate is published under number HTT202608380E, with supporting test report HTT202608380ER issued

Covered models (12): 4850, 48100, 48160, 48170, 48180, 48190, 48200, 48320, 48340, 48360, 48380, 48400.

The series shares a single 48V platform design, so one test campaign with the 48100 as the representative module covers the complete range. This matters commercially: you can stock multiple capacities against one EMC certificate instead of tracking per-SKU compliance files.

Standards covered by the certificate

• EN IEC 61000-6-2:2019 - immunity for industrial environments
• EN IEC 61000-6-4:2019 - emission for industrial environments
• EN IEC 61000-3-2:2019 +A2:2024 - harmonic current (reference)
• EN 61000-3-3:2013 +A2:2021 +AC:2022-01 - voltage changes and flicker (reference)

Immunity: Tested per EN IEC 61000-6-2:2019

Immunity tests simulate the real electromagnetic stress a battery faces in the field. The EMC report for the 48V series records:

• Electrostatic discharge (ESD) - ±8 kV air discharge and ±4 kV contact discharge: PASS, satisfying Performance Criterion B (temporary degradation allowed, self-recovery after the test).
• Radiated radio-frequency field (RS) - 80 MHz to 6 GHz at 3 V/m and 10 V/m: PASS, satisfying Criterion A (no degradation of performance during the test).

Both results matter for real deployments. ESD events are common in telecom shelters and industrial cabinets - exactly the environments our telecom backup modules live in. The 80 MHz - 6 GHz RS coverage also maps to today's wireless environments (LTE, 5G, Wi-Fi) without performance drop-offs.

Emission: Tested per EN IEC 61000-6-4:2019

On the emission side, the module was tested against the industrial limits of EN IEC 61000-6-4:2019 and passed - meaning it does not generate disturbance above the allowed levels that could interfere with adjacent equipment, sensors or communication links.

What the CE Mark Means - and What This Certificate Covers

The CE mark is a self-declaration that a product satisfies the applicable EU directives. This certificate covers the EMC Directive 2014/30/EU scope for the ZVEPOW 48V series - so the accurate claim for these modules is "CE certified". Other directives may apply to your complete system (for example grid-connection or equipment-specific rules), and your integrator will confirm those at the system level. For the modules themselves, this certificate is your verifiable evidence of EMC compliance.

If you are comparing suppliers, our overview of sodium-ion battery manufacturers explains how serious manufacturers document such certificates - and the checklist below shows what to verify.

How to Verify a Supplier's EMC Certificate (Checklist)

• Match the certificate number and the test report number - they must cross-reference (HTT202608380E / HTT202608380ER).
• Confirm your exact model number appears on the covered list - a certificate for one SKU does not cover the whole range.
• Check the issuer and the date: an active certificate is issued by an independent, accredited testing body and stays current.
• Ask for the applied standard editions (the +A2:2024 and +AC:2022-01 amendments matter for harmonised status).
• Request the Declaration of Conformity (DoC) - it ties the certificate to the legal manufacturer.
• If capacity ranges vary, verify the full series is covered by one test campaign (as with the 12-model 48V platform here).
