I'm going to take the question seriously. I don't see any reason to just assume they're a troll just because they're new, and this is a question people have genuinely brought up in my life.
Yes, there is a lot more electromagnetic fields going on than in a gas car. It's part of why there is no AM radio (it would interfere).
The battery itself doesn't give off EMFs. Actively using it a lot does (via the drive motors, for example, so while you're driving).
Whether or not this is concerning, since you asked, there isn't really any evidence to support that that I am aware of. If it were concerning, there would be more detrimental health concerns if you lived near a big electrical transformer or something on your street I'd imagine. There'd also be much larger impacts on anyone working near large industrial motors (e.g. plants, mills, electricity generation) as they produce much stronger fields, but I don't know of any health impact in these cases either. At the end of the day, it does not seem to be anything to be concerned about.
Its admirable that you are taking the question seriously, which may be the right thing to do, but saying that, this OPs post follows the very definition blueprint of a troll type post.
1. Joined website recently, no posts
2. Posts topic that would entice a lot of discussion. ("What about this controversial thing here, whats everyones thoughts on that?"
3. doesnt provide ANY discussion on their own, or background for their question. Lobs question in and basically says "discuss... thanks"
Usually, when this type of post is NOT a troll post, it has a format more like :
==============================
Hi, I was thinking about XXX, and I read this paper called YYY or came across this research ZZZ and was wondering about............blah blah blah. My opinion is XXXXXXXX.
==============================
Since the format this OP chose to post in is basically the exact format that someone lobbing a troll post into a popular form does, I think people should be forgiven for believing its "not serious". In this OPs case, since the Location is listed as "london" we would also "assume" (which may be incorrect) that the OP speaks fluent English. Not speaking fluent english is normally another reason why someone posts short form questions like that, with no background, but in this case the assumption would be the OP speaks english fluently since location is a English based location.
So, yeah, looks like a troll post to me too, but I commend you for taking it seriously, and providing a serious answer.
