Re: The EV Mandate’s Fine Print EPA orders an electric battery warranty that isn’t legal or practical.

The comments section over there shows, even more than the article, that troglodytes are the WSJ's ( or at least the editorial section's) base of support.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Re: The EV Mandate’s Fine Print EPA orders an electric battery warranty that isn’t legal or practical.

What a steaming pile of do do.

Legal? I am not a lawyer, and have no comment. Maybe they are correct. Or not. I doubt it.

an eight-year or 80,000-mile warranty. Auto makers will also have to certify that EV battery performance doesn’t decline by more than 20% over five years or 62,000 miles, and 30% over eight years or 100,000 miles.
My 2014 LEAF did well better than this. And batteries are getting better. Why is this a practical problem?

and some 90% of rare earth mineral processing occurs.
Not all battery chemistries use scarce materials, LiFePo, for example. No Lithium or Sodium chemistries that I'm aware of rare-earth materials... those are used for permanent magnets and for batteries used in hybrid cars. Nickle lanthanum hybrid car batteries... sure, but also gasoline cars use rare-earth materials.

Their pervasiveness is exemplified by the modern automobile, one of the biggest consumers of rare-earth products. Dozens of electric motors in a typical automobile, as well as the speakers of its sound system, use neodymium-iron-boron permanent magnets. Electrical sensors employ yttria-stabilized zirconia to measure and control the oxygen content of the fuel. The three-way catalytic converter relies on cerium oxides to reduce nitrogen oxides to nitrogen gas and oxidize carbon monoxide to carbon dioxide and unburned hydrocarbons to carbon dioxide and water in the exhaust products. Phosphors in optical displays contain yttrium, europium, and terbium oxides. The windshield, mirrors, and lenses are polished using cerium oxides. Even the gasoline or diesel fuel that propels the vehicle was refined using rare-earth cracking catalysts containing lanthanum, cerium, or mixed-rare-earth oxides.
But of course the Murdock owned WSJ doesn't consider gas car's use of rare earth elements a problem. Oh, never.

China is leading in EVs because they have invested in EV and battery technology. One reason why the USA has largely not is the idiots that write the WSJ. Thanks, guys.

Yes, I could not believe what I was reading in that article. My 2019 SL Plus has an 8-year, 100,000-mile battery warranty with capacity to remain above 8 bars (we can argue exactly what capacity percentage that is, but probably around 70%). It has about 85% capacity (according to LEAF Spy) with over 62,000 miles in the Phoenix, AZ climate so it is still meeting that warranty requirement--will be interesting to see if it makes the 70% at 100,000 miles. LEAFs in cooler climates should have no trouble exceeding these warranty requirements.
