# 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.

## Key values

- **Category:** elf magnetic
- **Emission bands:** DC and traction ripple; Inverter switching harmonics
- **Environments:** vehicle
- **Duty cycle:** Proportional to current draw: highest under hard acceleration, regenerative braking and DC 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.

## Measure with

- ELF gaussmeter (power-frequency magnetic field)
- Intermediate-frequency magnetic field meter
- Logging EMF instrument
