This ain't a wrangler forum
That's right, but because the KL doesn't support smart alternator charging and Wranglers do I figured I'd post real world data to show how smart alternator charging works.
To recap like i've said all along
1. Alternator voltage on the KL is based on temperature and is controlled by the PCM/BCM
2. KL's don't support smart alternator charging as tested with my 2021 3.2 KL
3. No one can give a single piece of data to support smart charging on a Cherokee KL
4. I updated this post to show the behavior of smart alternator charging to make it easy for someone to reference how smart charging works so they could prove me wrong.
So, smart charging occurs when the SOC as measured by the IBS is greater than 90%
If that's the case why did my tests and videos with my 2021 Cherokee show a SOC of 92% and the same high voltage charging that vehicles without smart alternator charging does? Looking for a real answer here no bullshit excuse.
I then had a chance to do some longer extended testing to show how the smart charging works long term when the SOC is high enough to enable the feature.
What you see is the voltage around 12.6-12.7 and it stays there. In fact what you are seeing is that when the SOC gets high enough the battery actually is being slightly discharged. In some cases the alternator is not charging the battery at all (when the current to the IBS is high and negative) showing a 40-60amp draw. Then the alternator starts providing current but just enough to slowly drain down the battery around 4amps of discharge. Then when the SOC gets low enough the alternator kicks in and provides a large amount of amperage (over 100amps at certain points) and then stops charging when the SOC get to a higher value. This cycle happens over and over providing the SOC is above 90%.
This is very clear data and information this behavior is NOT seen on a Cherokee and the Cherokee KL does NOT support alternator charging until someone measures the IBS and shows this exact behavior, why is that such a hard concept to grasp for some people? I get it though these days people read someone and it has to be right. No children facts/data/testing don't lie.
I challenge someone to grab J-scan, or OBDlink and prove smart alternator charging exists i'll even paypal you $50.
It's weird that
@MikeR. did a log of OBDlink and his cherokee didn't have smart alternator charging nor did his voltage ever drop like it should if he had Smart Alternator charging.
My god do you like hearing yourself talk
Youre the only one here who is fiercly engaged on this ground war of yours,
Under the 1949 Geneva Conventions collective punishment is considered a war crime. "No general penalty, pecuniary or otherwise, shall be inflicted upon the population on account of the acts of individuals for which they cannot be regarded as jointly and severally responsible."
if you take this seriously I will cry
Don't you have some makeup to put on your battery so it looks better, or maybe on your car or something, thanks for trying troll you have posted nothing meaningful. But since you think you are a wealth of information prove me wrong.
