You would not need to do a BMS reset, that is only to tell the system that a new battery has been installed. I don’t think you need to do the 8 hour thing, as the state of charge would not change significantly in the few minutes that it would be disconnected.
No, not at all! It's only if the charging characteristics change, which only occurs when there is a new battery or if you are adding in something like an aftermarket stereo that does a large power draw.
thanks
You're welcome!
Actually, I think it will overcharge the new battery if the BMS thinks it's an old battery. Older batteries tend to have some sulfation on the plates which require a higher charging voltage to overcome that added cell resistance. As the battery ages, the system will increase the charging voltage so if you don't reset the system, it will use a higher charging voltage which can be detrimental to a new battery. It's not a "useless" system as someone suggested; it's just that in the past, our cars didn't have such things primarily because we had old school regulators and such without computers. Engineers found that as batteries age, they change how they accept a charge, etc. so found that battery life can be prolonged with a charging strategy that is optimized for the battery's condition. How much it prolongs the battery life I can't really say as I'd need an identical car without the BMS system to compare how identical batteries would fare in both cars being operated the same way. Of course, even that isn't necessarily valid as you could have a battery with a defect that makes it not last as long as "normal". I just trust that the engineers know what they're doing and our batteries will last as long as possible with their system.
That is precisely how it's supposed to work. Older batteries require higher charging voltages due to sulfation of the plates which introduce charging resistance. I checked my car and the battery has been in operation for 872 days which pretty much coincides with the production date on the window sticker (Sept. 2020) that was on the car from the factory.
Correct.
Ford introduced the BMS technology in 2011, so your '19 truck does use it.
Excellent info thanks!
