EU Regulations for E-bikes & Pedelecs (Part 3) Electromagnetic Compatibility

Laws & Regulations

BRUSSELS, Belgium – All electric devices influence each other when interconnected or close to each other. Sometimes one may observe interference between a TV set, a mobile, a radio and a nearby washing machine or electrical power lines. The purpose of electromagnetic compatibility (EMC) is to keep all those side effects under reasonable control.

EU Regulations for E-bikes & Pedelecs (Part 3) Electromagnetic Compatibility

Legal EMC requirements are in Directive 2004/108/EC. Pedelecs with an electric motor having a maximum continuous rated power of 0.25 kW and assisting up to maximum 25 km/h must comply with this Directive.

The Directive specifies legally-binding protection requirements. As far as the above-mentioned pedelecs are concerned, most of these requirements are covered by EN 15194. However, the European standardisation institute CEN should review EN 15194 to ensure that all obligations resulting from the Directive are covered by the standard. The publication of a reference to the standard in the Official Journal would then turn EN 15194 into a harmonised standard under the EMC Directive. That would mean that a pedelec that complies with EN 15194 would be presumed to comply with Directive 2004/108/EC.

EMC assessment

In expectation of such a harmonised standard, the manufacturer has to apply his own methodology for the EMC assessment. He has to prepare technical documentation to demonstrate evidence of compliance with the requirements and have that documentation available. He may opt on a voluntary basis to involve a Notified Body during the conformity assessment procedure. The manufacturer is also required to supply the pedelec with an EC Declaration of Conformity, the minimum content of which is specified in the Directive. He has to affix the CE marking. This however, cannot be done unless the product also complies with the Machinery Directive and the RoHS Directive.


The EMC Directive requires that pedelecs be identified by type, batch, serial number or any other information allowing for the identification of the vehicle. In order to facilitate traceability, the actual manufacturer needs to be identified by name and address. In cases where the manufacturer is located outside of the European Community, also the name and address of the authorised representative or (where neither are in the Community) the person responsible for placing the pedelec on the Community market needs to be given. This information has to accompany the pedelec.

Next to the EMC Directive, the EN 15194 has some additional marking requirements. All electrical and electronic sub-assemblies (ESAs), except cables, shall bear the following indelible and clearly legible markings:

a) make or name  of the manufacturer of the ESAs and their components;

b) trade description
