I don't know what that means, I couldn't find an answer with a quick search, but I assume it's some kind of automotive certification.
Yes, specifically the ASE automotive electrical certification. I took the prep class at Yuba College from a multiple-decade industry veteran, and I got an A. I still have my notes. I passed the ASE A6 exam years later with a good score (someplace in the nineties, I forget exactly) when it was relevant to my employment.
Well, I have an electrical engineering degree
Relevant if you had studied flooded batteries or automotive charging systems, which you clearly didn't
Irrelevant. I also have a ham radio license, so I know first hand how irrelevant that is to this discussion.
I also have a link to Bryan's Garage above
Your link is meaningless, but if it were relevant, what it would show is that alternator charging voltage CAN BE TOO HIGH. The documentation for my 12V nominal LFPs explicitly states that charging voltage over 14.6 is undesirable and should not exceed 14.8 for more than short periods, nor go over 15V at any time. Sustained charging at 15V could cause damage.
So to reiterate, you don't know about LFPs, you don't know about alternators, and as a result you don't understand the citation you've provided (which as a random blog post without any explanation of why alternator output voltage is what it is, is frankly the worst quality citation you could have provided.) And your EE clearly isn't relevant here either since you don't have enough related knowledge or experience. You could clearly hang the knowledge on that, but also as clearly haven't acquired it. Meanwhile my cert and the experience I have with LFP batteries as an RV tech and while creating my own systems is directly relevant.
