charge limit

[RickMachE]

Yea, I agree. The simple answer for most people is to average the drop in SOC from wherever you start over a couple weeks. Take that percentage, divide it by two and add the result to 50. That’s your best max charge setting. Feel free to charge higher time to time if you need it, and don’t worry about it.

Wait, that's the SIMPLE answer? ?

Yes and Yes. Did it, and didn't tell.

grr so I've actually lost more than I thought. I'm at 93.3%SOH, range when full is now 271. (65k miles.. so really not that upset)

That's why I started the thread. It USED to say that. It no longer does. At least I cannot find it in the online manual.

In the online manual, expand (+) the section called "Starting and powering off" then click on "Preserving your high voltage battery". Under Overnight Charging is still specifically mentions maximum charge level to 90%.

Just checking that you know that recharging a battery and refulling a gas tank are not alike things at all?

Just checking that you know that charging to 100% every time is shortchanging yourself because the battery will be weaker in future years?

Yes I know, but why shortchange yourself by not charging to 100% ?

If it's not good for the battery then Ford would limit the maximum SOC (which they do around 9% buffer).

I don't stop charging my watch, phone, laptop, tablet, flashlights, etc at 80% - always charge to 100%.

And BTW I don't keep my vehicles past the warranty period so I typically will sell or trade it in.

The 2024 manual says the following:

Charge to whatever percentage you want to. We don't give a rat's ass what you do. At 8 years / 100,000 miles, despite what the Car Scanner app tells you, we're going to run a proprietary calculation to show 70.0001% battery capacity. So have at it, and beat the leaving crap out of your battery!"

My kinda manual?

My attitude still is the same as it was the day I was supposed to collect the car from dealer after a 2 week delay because some bozo in IT forgot to program all 360degrees of latitude into e-call which led to Ford putting a STOP on collections, sales, demonstrating etc.

That was the day after I gave away my Outlander ? so had no transport and had to rent in an Enterprise van to the rescue?

Ford tried to explain how the wait would be worth it as the car was so special as their flagship entry into the EV market.

I mean, they were right about special I eventually found out??

However, they did just needed their minds focussing.

I explained to them that the car may be all the world to them but was was not yet to me, it was bought to be put to work and irrespective of all their bull, if it don’t perform like every car I bought before it the Pony would be advertised in Autotrader by the end of the first week?

Needless to say, when I eventually did get it the car performed beautifully and still does, even with charging frequently to 100%, using DCFC very often and now at 71,000 miles is probably the same battery performance as day 1.

Still love the ‘Stang for what it was and still is and it continues to work hard and earn its keep and I just don’t worry about anything?

Did you lose that much or is it just November and it’s cold outside?

Do these cars lose SoH in the cold as well as range?

Apple Watch Ultra will limit itself to 80%, and the iPhone 15 now has an option to limit charging to 80% as well. Manufacturers are starting to do these things to prolong battery life, whereas before, how long a charge would last was all that mattered (for the first few years anyway).

For people who keep their vehicles longer, unnecessarily charging to 100% is what shortchanges them for future range. Charging to 100% every day might leave them with 30 miles less range in 8 years than charging to 80%.

Battery capacity is less in the cold for sure.

How that shows up on a state of health scan? No clue. I’m not sure how people are measuring it.

 

[Teslaeata]

I’ve been using the Car Scanner app with a Bluetooth OBD device and have seen no degradation in SoH this year, in fact it increased by 0.5%, but don’t think I started monitoring as far back as last winter, will be interesting to see if temperatures affect the calculated SoH in the coming months.

No.

Yes let's agree to disagree.

I don't charge daily to 100%.
Once a week is all I need to charge to 100%.

Plus with a 8 year HV battery warranty, I am not worried.

My 3rd EV and have never had to exercise the battery warranty yet...

 

[Teslaeata]

No.

Thought not ? I’ll keep monitoring purely out of professional interest, not worrying about mine, though.
