Electric vehicle cabin (traction and charging)

EV cabins contain low-frequency magnetic fields from battery cables, traction motor and inverter, strongest in the footwell and over the pack, with a separate profile during fast charging.

Field strength by distance

Mitigations, most effective first

Measure at each seating position while driving and while charging, logging rather than spot-reading.
Peak conditions occur transiently under acceleration and regeneration.
Do not sit in the vehicle during DC fast charging if minimising exposure matters to you.
Charging currents are the largest in the vehicle's duty cycle.
Use a meter with bandwidth to at least 100 kHz to capture inverter harmonics.
A 50/60 Hz-only gaussmeter misses most of an EV's spectrum.

Why no value is published at 10 cm

Cabin levels are highly model- and position-specific and depend on cable routing. Measure at the seat position of interest during acceleration and during charging; published generic ranges are not reliable across models.
