I don't see any way to steal electric car battery without actually stealing the car. Its big, heavy, scary (and actually dangerous), and highly integrated with the car
Definitely not the current versions of batteries but those will drop in size over a short period of time. Maybe instead of stealing the battery itself the energy from it would be illegitimately transferred off ... "siphoned off" if you will
When I first read the top-level comment I initially thought the same thing.
After reading your comment I'm thinking that we'll eventually see start seeing YouTube videos crop up of three guys with sawzalls and angle grinders cut out a battery onto a skateboard and hoist it into the back of a truck in minutes.
600lb motorcycles aren’t usually integrated internally into a several tone vehicle and mostly don’t discharge high voltage dc into anyone trying to steal them.
These are merely operational details. With some training and a little bit of Darwinian selection, I could easily see the same guys that mastered stealing catalytic converters in 2 minutes [1] shifting their focus to EV batteries. It might take them longer, say, 5 minutes, but the payoff is far higher.
