Sounds like this might improve safety, and give Tesla an edge.

Cool feature, but haters can interpret this again as: "You see! Something is wrong with the Model S!"

Nice to see that Tesla keeps improving, but I wonder what kind of weird spin all the EV hating blogs are going to give to this.

There are many things wrong with the Tesla model S. It's disingenuous and perhaps hateful to try to portray otherwise. It's hateful disingenuous weird spin to stereotype critics of Tesla's faults, as Tesla haters.

All manufacturers and designs have their faults and dangers, INCLUDING TESLA.

Battery pack fires a thing of the past? U.S. Patent Number 8618775 (Tesla Motors)

"The present invention relates generally to detection of and response to potentially hazardous conditions in an electric vehicle battery pack, and more particularly but not exclusively, to detecting and responding to potentially hazardous over-current due to internal short circuit to limit possible excessive thermal conditions of the individual battery cells and modules."


"What is needed is an apparatus and method for to detecting and responding to potentially hazardous over-current due to internal short circuit to limit possible excessive thermal conditions of the individual battery cells and modules."


"The system responses could also include introducing a secondary short which would source sufficient current to activate the fusing system and stop the current flow in the internal short that itself wasn't sourcing sufficient current, or simply trigger an active fuse or other interrupting mechanism in series with the shorting element(s).

"Features/benefits include an ability to detect and respond to potentially hazardous over-current due to internal short circuit to limit possible excessive thermal conditions of the individual battery cells and modules, such as the type used in electric vehicles and similar applications."

Very interesting. May be this will be on the Model S by mid-year? If they could make it a retrofit, that would be even better.
