Would it be worth it to disconnect the HV battery and LV battery? Obviously the car would not be able to be moved around on its own power but I would assume a collision shop is used to moving non-operational vehicles around on dollies.
Im sure any shop would be, but I dont believe that is what this OP is talking about. Since in another thread the OP discusses the accident and "the car drives fine" this isnt about the shop moving a car around, etc.
it appears to me that the OP has had an accident, the OP is still using the car, waiting for their appointment for repair, and since they cant plug it in for some reason or other is wondering why the car is not sleeping / draining power.
I doubt the OP wants to disconnect the battery and have it sit, since they are saying they are still using the the vehicle. I also doubt very very (very) much that any Tesla SC will even agree to look at the car, since the car is damaged, so any idea of something being "not normal" is easily hand waved away by them, saying "yes, its not working properly, it was in an accident, please check back with us after its repaired".
Since the OP appears to not be able to plug it in, they are now having to figure out charging more than they intend to, and are wondering if there is anything they can do.
Thats my reading on this thread, anyway.
I am fairly sure there is nothing Tesla will do, and engaging them will be a futile exercise until the car is repaired. OP could stop drain by doing what you say if they dont intend to drive the car (if I read into this wrong). Otherwise, its just "charge it more than you intended".
