This is nothing new, but, it is going to get worse with so many more hybrids and EVs on the road daily. Talk to fire fighters and you’ll learn they have special protocols for dealing with these vehicles, because of the dangers of fire when in an accident. They’ve told me the dispatchers are tasked with asking what kind of vehicle is involved with the accident, as they’ll respond differently. And, of course, batteries can just combust
The Science of Why Electric Vehicle Batteries Are So Dangerous
In a recent op-ed, the Washington Post outlines how Tesla’s battery issues and fires may not just be due to poor design and manufacturing but a side effect of electric vehicles relying on lithium-ion batteries.
The Washington Post reports in an op-ed titled “Tesla’s Big Batteries Aren’t the Fire Problem. Lithium Is,” that Americans should be questionubg whether lithium-ion powerpacks should be used for applications such as electric vehicles. The piece argues that the science of lithium-ion batteries make them inherently dangerous.
The Washington Post writes:
The large-scale use comes with significant risks, although most modern power systems choose this formulation because it boasts higher energy density, as well as greater charging and discharging efficiency. However, lithium-ion batteries have a volatile, flammable electrolyte. So, while there are safeguards to avoid fires, all the combustible ingredients are still there. Flames can accelerate through chain reactions, known as thermal runaway.
Big batteries are made up of several cells packed together. Current is constantly flowing inside, which generates heat. If there are no barriers between the components, a failure in one part quickly cascades through. While elaborate (and critical) equipment for cooling the system is put in place, it draws on the energy of the actual powerpack and reduces its output. In addition, when charged, a coat of lithium metal can form on the surface and dendrites, or needle-like structures can grow, and lead to short-circuits.
Both the Washington Post piece and the Breitbart piece spend a bit talking about how dangerous the batteries are, and, quite frankly, it might be a bit overblown. Lithiums have been around for quite some time now, and, while we hear about real issues with cellphone and vape batteries here and there, with them banned from being in checked airplane baggage, it’s still rare. But, with more EVs, and mass production, could it be worse?
The Washington Post piece, which looks like it originally came from Bloomberg, does actually make recommendations on replacement technology, but, here’s the thing: none of them are truly viable at this time. And this will be used by the climate cultists to recommend that citizens be stopped from having EVs and just take mass transit, bike, or walk. That’s what they do.
