INTERACTIVE LESSON & SIMULATOR
Interactive Explorer: Electric Vehicle EMF Zones
Audit magnetic fields across the cabin: inverter front footwells, battery floor pans, regenerative braking, and DC fast charging.
What was tested
Germany's Federal Office for Radiation Protection (BfS) measured low-frequency magnetic fields inside a range of electric vehicles under real driving conditions, including aggressive (“sporty”) driving that draws higher current, and compared the measurements against two benchmarks: the EU's 1999 recommended reference levels, and the stricter health-protection limits those reference levels are meant to conservatively approximate.
The two-tier result
In some vehicles and driving conditions — particularly sporty driving, which draws more current — measured fields exceeded the EU's 1999 reference levels. But reference levels are deliberately conservative screening values, not the health limit itself. When BfS ran detailed computer simulations of the actual electric currents those field levels would induce in a human body, the results stayed within the limits recommended for health protection in every case tested.
Where the fields are strongest
Consistent with where the current-carrying cables and battery pack sit, measured fields were generally higher near the floor and around the legs and feet than at head or torso height — a spatial pattern broadly comparable to fields measured in electric trams and subway cars.
What this does and doesn't tell you
This is one national agency's 2025 testing program, not an independent replication or a long-term health study — treat it as a credible screening result rather than a final word. It does indicate that, for the vehicles tested, everyday driving stayed within health-protective limits even when EU reference levels were locally exceeded.
