Does anyone know if the EMF has been tested/measured for the LEAF? If so, is the data available?

Better get the SAR of the key fob while you're at it... That will be the next question!PaulScott said:DeaneG said:It's important to keep in mind that the act of driving a car on a public highway is many orders of magnitude more dangerous than exposure to the usual electromagnetic fields.
I totally agree. I'm only asking because I regularly talk to large groups of people about EVs and get this question a lot. I prefer to give them an answer based in fact rather than a guess. If the info is available, I'd like to know the source, if it's not, we'll need to get it at some point.

Is there a reference on that to put actual numbers to the ratio?EVDRIVER said:A cell phone at your ear has about 1000 times more radiation then one would get from riding in the LEAF, (snip).
Great job! Thanks!JessEV said:I had the same question about EMF in the Leaf.[...]
So I bought one of these Triflow measurement devices and did some testing.
I am impressed that Nissan has been able to achieve magnetic fields this low in the Leaf. Magnetic field is proportional to current. 20KW (during acceleration)/400V = 50A DC going into the car's inverter. The inverter outputs AC to feed the synchronous motor at a frequency proportional to the motor's RPM and vehicle speed.JessEV said:I had the same question about EMF in the Leaf.
it looks like Prii and other well made cars are in the sub 5 milligauss range. The Tesla roadster was measured at 10 mG at idle and 50mG on full throttle.

- Leaf: measured at driver head and torso fluctuated between 1-5mG, no noticeable diff whilst accelerating
- Leaf: measured at driver feet hovered around 5-10mG, no noticeable diff whilst accelerating
- Leaf: measured in the back seat area was well sub 3mG, and seemed to jump up a little only when braking
- Leaf: measured in the back hatch area while CHARGING - 100mG - (yeah that was high, but who cares, no one is in the car)
- my ICE car: 100mG+ everywhere in the car
