Among Tesla’s Patents Are 25 For Fire Prevention

Like literally every other energy source, electric vehicles do come with certain risks. Among the biggest risks for EVs is “thermal runaway”, wherein rising temperatures cause temperatures to further rise in an unstoppable incident commonly referred to as “fire”.

So it should come as no surprise that Tesla has a number of patents relating to how to deal with thermal runaway. With these patents now open game for other automakers, can we look forward to better and safer batteries?

uAutoInsurance identified 25 Tesla patents relating to thermal runaway detection and prevention. Why is this so important? Because the media is ready to jump on any whiff of electric car fires, as proven by the Tesla fire incidents, as well as the uproar over an isolated Chevy Volt battery catching fire some three weeks after it underwent crash testing.

Needless to say, if the public is going to believe in EV adoption, these cars have to be safe. Tesla knows that as much as anyone, and hopefully these patents can help other automakers speed the adoption of electric vehicles.

    P# 8445126 uses metal air cells to help the absorbing of hot gas from the thermal runaway of the current system. Now that is IP worth having… No disrespect to the inventors.

    App# 20100136424 adds volume to cells by adding a secondary wall that when multiplied by 8K does not appear to reduce pack size or cost.

    Aside from the intention and novelty of the applications, it is apparent to me the understanding (or lack of) of the so called “thermal runaway” event.

    Detecting a thermal runaway after the fact is like checking if a dead person is breathing. Better yet checking if the breathing activity characteristics during the event,

    Not sure this will be the turning point in EV adoption.
