EU Standard for E-Bike Batteries Published

Laws & Regulations

BERLIN, Germany – The European Committee for Electrotechnical Standardization has published the European standard EN 50604-1:2016. It defines a unified, Europe-wide safety standard for lithium-ion batteries used in e-bikes and Light Electric Vehicles (LEVs).

This new regulation improves the safety of e-bikes (also named pedelecs) and other LEVs like electric motorbikes and scooters, and it provides a robust legal framework.


The new standard was proposed by the ZVEI (Zentralverband Elektrotechnik- und Elektronikindustrie, German Electrical and Electronic Manufacturers’ Association) and the ZIV (Zweirad-Industrie-Verband, Germany’s Two-Wheeler Industries Association) in collaboration with the Battery Safety Organization, BATSO.

Urge for standardization

These associations urged for the standardization of e-bike batteries as they must be protected against overcharging, deep discharging, short circuits, extreme temperatures and vibrations. The charger and battery pack must match, and chargers must only be able to charge the batteries for which they are designed. So chargers and batteries which belong together must be able to identify each other unambiguously.

‘Need for clear technical guidance’

The association note that two-wheeled electromobility has been a reality for some time now. Already over 2.5 million e-bikes and light electric vehicles are on the road in Germany. “In view of this e-bike boom consumers, dealers and manufacturers all need clear technical guidance,” states Siegfried Neuberger, ZIV Managing Director.

Highest possible level of safety

Managing Director of the ZVEI trade body added, “E-Bikes, electric two wheelers and their components must all be manufactured to unified, high quality standards, so as to guarantee the highest possible level of safety.” Stephan Scheuer, Chairman of the Battery Safety Organization, BATSO, worked on the development of the basic technical requirements. He explains “In contrast to the batteries of electric cars, those on e-bikes are accessible externally, and most of them are removable. This gives rise to specific safety requirements to better protect the user. The new EN 50604-1 standard sets the benchmark in this respect.”

44 page document

EN 50604-1 describes the general safety requirements and test methods for e-bike batteries. It’s a 44 page document that costs € 73.40 and can be ordered at EN centres based in all EU member states.
