Yeah also they did not remove anything from the 18650 cells Tesla/Panasonic designed their own cells. 18650 just determines the size. It does not tell you anything about whats inside. The official story is not in on that car yet. But I have seen ICE cars catch fire for no appearant reason as well and its about 10x more common per Miles driven!whatever wrote: ↑Jun 18, 2018 1:41 amSeems tesla has removed the two fuses normally found in 18650 cells ( cid fuse and the other one I forget the name of), the only protection at the cell level is the thin fuseable link. Seems the 2170 cells also dont have the internal fuses either ( one is pressure based the other one is temperature based).
Having some sort of fuse that is temperature dependent I think might be a good idea.
Ideally knowing exact temp and voltage of each cell at all times would be nice but is technically very difficult .
The model S is designed to Vent the fire in the location it did in the video.Hillhater wrote: ↑Jun 18, 2018 6:15 pmThe points to consider are .....
1) Tesla cells can ignite and fuel a serious fire... (there have been doubt that they are flammable)
2) What is the recommended way of dealing with a pack fire such as that one in the video ?
The difference between a battery pack fire and a conventional ICE fire is ..
....the ICE fire can be controlled and extinguished using conventional methods and materials (water, foam, powder, sand etc)...
.....but extinguishing a fire inside a battery pack is practically impossible due to its chemical nature and restricted access to the seat of the fire.
