How often to charge

[SnBGC]

Isn't 100% set through the Charge settings really 85% as Ford built in a buffer?

100% displayed is about 96% actual.

Charge to 100% and live your life. The minuscule amount of battery life you will lose by charging to 100% is not enough to start threads. 100 people will tell you 100 different things. I have charged 100% every night 17k miles. 230 in summer 200 in winter in Sacramento. I drive my car like I stole it enjoy it ?. I love people that charge 1 time a week ect or to 50 or to 80 or whatever they do enjoy that BS people. The more time I can drive and not charge I’ll enjoy my car and life.

FLAME ON?

One reason to not charge to 100% is because you want full regenerative braking available to you. At 100% you are more or less relying solely on the friction brakes. That isn't to say that that friction brakes aren't up to the task. As someone who lives at the top a hill, I can tell you that there is definitely a difference at going down the hill at 100% SOC and 90% SOC.

What section is the 30% tax credit in? How do we apply?

Isn't that what "L" is for? Every other automatic transmission vehicle, unless manually shifted lower, relies on its wheel brakes to decelerate on a decline does it not?

You don't apply for tax credits. You do your taxes and complete the right form.

The 30% tax credit is form 8911.

L and one-pedal driving both use regenerative braking to slow down. That requires that the battery not be full, otherwise there is no place for the electrons to go. Keep in mind that the car doesn't have an automatic transmission with multiple gears. Just the electric motor(s) and a reduction gear(s). So, if regenerative braking isn't available, it's completely relying on the friction brakes.

I charge to 100% displayed every day and I have regen immediately once I start driving. Regen is more efficient at lower states of charge but still exists.

I don't live at the top of a hill though..... ?

There's limited regenerative braking at 100%. You get some, but not nearly anything like you get below 90%. And it isn't efficiency, it is effectiveness.

Typically, Li-ion batteries like to be somewhere around 50% State of Charge (SoC). They tend to degrade less around the middle range of SoC. They tend to degrade more when at the two extremes in SoC (approaching zero% or approaching 100%). The “Goldilocks Zone” is between 20% and 80% SoC. Since Ford built some buffer in at both ends of the battery, I normally charge to 85% indicated SoC, which is close to 80% gross SoC. ??

Have been reading and watching videos on charging and most say normal everyday is 20-80%. My MME is due to start its build next Monday so I don’t have any experience to go on either but my question to the group is what about Li-iron phosphate batteries which is what 2023MY has. Different make up, different pro and cons with denser battery slightly less capacity but greater number of charge cycles to name a few. Just wondering if anyone knows of any different guidance, I think as of now only some late model 22 Teslas have newer battery type.

75% is about when I start to see jail bars and the lower it goes the more jail bars I see. So I try to keep my SOC around or above that.

I know the OP doesn't have a GT, but I'm assuming all models have the same issue. GT's just have a tiny gauge to show performance degrade as SOC decreases, along with other factors of course.

80% daily is sufficient for my daily trips.

Everything I’ve read says LFP batteries will be introduced in the Mach-E sometime in calendar year 2023. I‘ve not found anything that says for all model year 2023.
Since LFP energy density is lower than the existing chemistry, it will likely only be used in standard range models to avoid excessive weight with an extended range LFP battery.

Of course. But saying there isn't any regen isn't totally accurate. Efficiency or effectiveness depends on your point of view and what you are trying to accomplish. (Stopping or harvesting.)

Whatever fits your use case. I typically plug in whenever I get below 50% and charge to 90%. Sometimes that‘s 2 days between charges, sometimes 2 weeks. If I know I have a long drive the next day, I’ll charge to 100% the night before.

In warmer weather I usually charge when I get below 40% and charge to 80%. Now that it is cold out, I'm usually charging any time I get below 50% and increased my preset to 85%.

85% is handy as you get 4 full bars on the dial. Sometimes when you charge to 80% the battery "cools" back down to 77-79% and only shows 3 bars. I think I'm going to stick with 85% for that reason.

If you plug in daily with 220 line, check with electric company because electric rates are much less at night. In Pittsburgh we have Duquesne Light. Rates from 11 p.m. to 6 a.m. "Super off-peak" are $.02/KWH, "Off-peak" $.05/KWH from 9 p.m. to 11 p.m. and 6 a.m. to 1 p.m. and "Peak" $.09/KWH from 1 p.m. to 9 p.m. Makes a big difference on you electric bill. You have to call your electric company to set this up.
