You misunderstood, if you require all this certification to change battery types. You wouldn’t be able to replace 12v sealed lead acid in an ICE vehicle with li-ion or other types.
It’s already a thing that happens, yes there is hell of other hurdles, but there’s nothing magical about changing battery chemistry type and the vehicle.
12V sealed lead-acid batteries are a standard size and chemistry... They are absolutely not comparable to a BEV battery. The lithium ion 12V batteries are built to the emissions standards and regulations of the 12V lead acid, that's a known quantity and a hell of a lot less energy. BEV batteries contain kwH of energy, they are significantly larger, are a nonstandard size on every single vehicle. Even if Toyota made it the same size and shape, the energy density might be enough to fail EMC regulations (without having to change the size and shape)
I don't know what else to tell you man, I work on electric vehicles for my job. Literally an engineer. You can choose to not believe me but it just isn't anywhere near as simple as you're acting like it is. Just because you think it's like swapping an alkaline AA for a NiZn AA doesn't make it true.
12v sealed acid batteries are not a standard size and chemistry by any stretch of the imagination. Even is sealed lead acid there is dozens of different chemistry and makeups in the batteries. Your ignorance in this is astounding for an engineer. But I also haven’t seen an engineer willing to admit they made a mistake as well….
You’re trying to claim Something isnt possible just because of a little red tape that can easily (in fact it already is dealt with) be met. It’s not a very good argument even. Its already done, yeah the size changes things slightly, but the precedence shows this is entirely capable of being done.
You can tell me what you want, but there is already a very real world example of this being possible. Sorry. Get your head out of your ass for two seconds and think about this.
