0% Battery watch out!?

[AtomicInternet]

Ford engineers the car to protect the battery and never lets it go to actual zero. You need to get this message and then let it sit for almost a month while it naturally drains to actual zero before you cause any damage. Ford has several defenses built into the battery management to protect against this kind of abuse.

As a final note: the only true way to flatten an EV battery below its absolute minimum is to park at a low point and then leave it that way without recharging for weeks to months as it will slowly self-discharge to a dangerously low level. Even then, the car will at a certain point defensively shut all systems down to slow the process.

Why?

 

[Sikkun]

So you’re saying if you drive any vehicle until there is no more energy source, the vehicle stops working?

Literally mind blowing. I never knew!

I’ve been beyond 0 (drove 5 miles more) never had any turtles.

The cold probably caused the turtles to appear for him.

I'm not sure if you all have wondered like I have about what happens.....does it shut off? Die on the spot?
I took my 24 Premium X to 0% battery and 2km range. Of course I got the yellow turtle earlier and acceleration was gradual. Red turtle came on. What was scary is that as I was driving around my area to see what happens I came across a scary moment. I was crossing highway on coming traffic and it started to crawl instead of accelerate. This was scary as I mentioned was crossing 2 lanes of oncoming highway traffic. I chickened out to run it to 0 km after that.
Has anyone ran it the 0 km or miles range?

But why? What did you think happens at zero beyond pain and suffering for all involved, including a very expensive battery?

Ironically, instead of hurting that battery, it's likely to increase the SOH value.

I'm just saying. ?

Every technical analysis I’ve seen shows that it does actually hurt the battery (albeit in small, maybe insignificant ways). It improves a SoH metric that we have visibility into, which is a proxy, not the real thing. Every time we swing into extremes we cause some damage. If you must drain the battery for a practical reason, then I’d say go for it. But this is akin to shooting a BB gun into your leg just to see how much it hurts. You know it hurts, and you know that it won’t kill you. So why the hell do it?

The most recent technical analysis are starting to backtrack considerably from the previous predictions of battery longevity and degradation. Which shouldn't really be too surprising as it catches up to the improvements in chemistry, thermal management, battery management,.........

I'm just saying that the OP is more curious than I will ever be about "what happens if"........ But I wouldn't be worried in the least about the battery being down to somewhere around 6% SOC for a moment?

I recall someone posting about how they didn't trust that the collision avoidance technology would work, so they stacked up stuff and then drove into it.

I have driven to 1%, not intentionally.

My son's vehicle had a broken gas gauge. It was explained to him that running dry isn't good for the fuel pump. We figured out a safe range, and posted it on the dash. He had a trip odometer displaying mileage since last fill.

He then ran it dry, TWICE. I setup an appointment for a new fuel pump and he paid for it. Costly lesson.

damn kids...i got one of those as well....lol

The most wonderful time of your life is when you come home, call out your kids' names, and hear nothing, because you're an empty nester... ?

Unfortunately there is still email, texting, phone, and video calls. "Dad, I think my battery is dead, here's how I tested it (wrong)."

That tracks with one of Tom's videos on State of Charge (though he was driving his Lightning). Hit "0%" and still was able to drive normally for several more miles to his destination.

Ford changed the software to add turtle mode when the battery gets low or cold. So just because you were able to drive past 0% in the past does not mean you'll be able to today. Depends on software level and how cold your battery is.

"Zero means zero" should be your mantra unless you like drama.

So, to be clear, you're saying we shouldn't do it?

Pls don’t ignore that these real world analyses are capturing current consumer behavior of not draining batteries or charging them to 100%. So yes, batteries are lasting longer than initially expected as an average and over a long period of time, but with the current behavior of staying away from extremes. I have not seen anything (not saying they don’t exist) that tests durability when tapping into the extremes on a consistent basis.

At the end of the day, I’m a consumer that is not interested in doing validation work on my dime on a $60k car to help Ford (or any OEM) test the damage that draining the battery would cause… and I will only follow Ford’s direction around how to and when to charge my vehicle. When Ford says charge whenever and drain as you please, then I might.

Note: In posting this I’m not trying to create controversy, but simply clarifying my point of view.
