>Tesla vehicles disengage the high voltage contactors when an accident is detected.

Great! Is there a visual indication that has occurred (see for example F1: https://www.racecar-engineering.com/tech-explained/f1-2014-e...). If not,

>You still don't want to cut through parts that can't be de-energized (ie do not push through the floor pan into your energy storage system).

You're right! That's why these things are standardized and labeled (http://www.solotogrouptravel.com/wp-content/uploads/2014/01/...)

>There is also a "first responder cut loop" which does the same, similar to the mentioned "RESCUE" lever on an aircraft cockpit.

The point isn't the function it's the labeling. As noted in other discussions (https://jalopnik.com/tesla-model-3-teardown-by-engineering-f...) of the model 3...there are no externally visible markers of where to cut until you open or remove panels and the markings themselves are unclear. The front first responder loop requires a 12V battery be connected to the vehicle if the frunk won't open under vehicle power.

None of this is about whether or not such systems exist...all of this is about the design and indication necessary of those systems in emergency situations. All F1 cars have different manufacturers...but they all have the same iconography and processes for disarming potentially energized systems (e.g., put the car in neutral, put out a fire, check if car is electrically safe). That commonality means it is easy to train first responders AND for first responders to know what to/not to do in an emergency.




I'm willing to bet my Hurst spreaders will get the frunk open sans battery. If you're cutting the car, it's already totaled and limiting damage to the frunk would be the last concern on my mind.


You willing to apply them to something that you are trying to open specifically because you are concerned about the electrical state of the car?

Your spreaders will open it like a tin can...but did Tesla rev the location in real time during manufacturing?


Yeah, prying the frunk open and cutting the battery cables is the first thing they do in the video


I went back and rewatched it. I completely forgot they forced it. I first saw this a couple months ago when our TC used it for extrication refresher. I have to admit, even though it is staged and the car is completely intact, watching those guys is money. Super smooth execution. The way he handled the halligan solo to create the frunk gap was pleasing to watch.
