I cannot believe that all of you EV folks did not comment on this.

Would you like to see images of gasoline vehicles burning? What is your point? They put batteries in a bus and it burned up. What\'s your point?

I never look at random youtube links, unless they\'re accompanied by some
rationale for doing that, e.g. \"A UFO photobombs an episode of <scotty
kilmer or Dan Carlin or somebody> about 8 minutes in.\"

WTF is the point of your stupid response?

Any energy containing system has the potential to release that energy in
an uncontrolled way if it is abused, or incorrectly manufactured.

What makes you think this one had a bad design?

Each \"cell\" in the battery at this size level should have had
monitoring circuitry to cut it out of an overload condition.
So the overload should have \"sparked\" a massive shutdown, not a massive
meltdown.

We don\'t really know this situation. In case of the Bolt, manufacturing deflect causes short of a powerful cell. Cutting it off won\'t help. Smaller cells are safer in this regard. 18650 can be shorted and destroyed, but not exploded.

Battery makers are trying to cut costs, and one way to do that is through larger cell sizes. I think VW, or BMW, not sure which, uses a cell about the size of a cigar box. I believe this also lets them give the cell more integrity without lowering the specific energy.

GM/Bolt cells are long thin rectangular pouch; so, in theory, should have better heat dissipation, other than the manufacturing defect. We have to give them credit for doing the right thing to recall (vehicle), replace (battery) and retool (factory). Let\'s wait and see.

Oh, I can barely wait! It\'s like trying to get to sleep on the night before Christmas!
