The only thing I can think of is the high voltage. I don't mind working with 220v but anything higher I tend to shy away with. I think some of the voltage systems in the battery packs can peak at 800v with most of them between 400v and 600v.
- beachy 3y agoThe EV is also DC, significantly more dangerous than the AC at the same voltage.
- Glawen 3y agoWell, no, AC is more lethal, also it contracts the muscles more easily. The high voltage ranges are different between AC and DC, with AC being lower than DC range due to the higher risk.
- aitchnyu 3y agoEven in college, I was taught AC passes on your skin away from your heart and is therefore safer at the same voltage. Is this a myth?
- petre 3y agoIt's complicated and likely not at all relevant at 50 or 60 Hz frequencies. You want the sqrt(2p/ωμ) formula if you're curious. https://en.wikipedia.org/wiki/Skin_effect https://en.wikipedia.org/wiki/Skin_effect
- beachy 3y agoMy understanding is that DC currents are more dangerous as the effect is continuous. Whereas there is some electrician humour that at least with AC you have 50 chances per second to pull away (Americans get 60 chances per second)
- junon 3y agoIt's not so straightforward. Volts, amps, and frequency (in the case of AC) all play a factor in lethality of electricity.
- SomeoneFromCA 3y agokeep in mind that peak voltage of AC is 1.4 of nominal. So keeping hat in mind, range is about same.
- ericbarrett 3y agoI've been shocked by 300V DC @ 500mA and I'll take the equivalent AC any day. Obviously both can kill you, but the DC was far more painful and instantly gave me 3rd degree burns. Also made me ululate some kind of tone I didn't even know the human throat could emit.

- ActorNightly 3y agoThe voltages are not going to be high enough to cause things like arcing through air. Basic precaution is necessary. The idea is not even that you yourself are going to replace it, its more for shops with equipment and skills to order individual cells, put together battery packs, and then just replace them in cars without worrying about compatibility.
