Daily Charging Limit Percentage - what's yours?

[JTWIRE55]

I know Ford recommends 90% daily charging, is that the level most people use or not?

85% for my everyday commute (200miles) to work.
92,000 miles and 95%SOH so far

Thursday-Monday 80%
Tuesday-Wednesday 100%
As far as actual need it'd be 25% on my work days and between 60 and 80 on my off days.

Many threads on this. There will be 16 responses with 21 answers, most of them worthless opinions...

The only reason to charge above 90% is if you need the range. There is zero need to charge less, since it is 82% of the actual battery.

You will see "I only charge every 5 days" answers which also aren't worth much. Five charges of 10% each use 50% of a charge cycle, as does one charge of 50%. Being plugged in all thrmtime allows the truck to use house current to warm the battery if below freezing (short bursts), and use departure times and remote starts without depleting the battery.

At home - 90%
At the office - 100%, because I want to keep my charging spot all day, and since I charge L1 at home, I want a deep charge if I'm taking the 60 mile round trip to the office. I don't take the truck to the office very often, once or twice a month tops. Most days I ride the commuter train.

Today I am at the office with the truck and I'm at 78% at a 4.3KW charging rate, arrived in the parking garage at 72%, it shows on FordPass that it will be done at 3:22, but from experience it usually goes until after 4.

I use 80% almost all of the time. If I am gearing up for a trip that will./might otherwise run me out of battery, I will up it to 100% for a few hours before I leave.

90% at home daily (when driven).

Plugged in all the time during the coldest/hottest times of the year. (This allows the truck to maintain the battery temperature as determined by the BSM.)

Going to go with 90% too thank you.

I work from home and there are weeks were I only drive my truck a few days out of the week. As we know, sitting at higher SOC during higher temperatures is harder on the battery.

Therefore I have adopted the following strategy (southern OH):

Peak Summer: 60%
Peak Winter: 90%
Everything Else: 80%

Road trips and longer excursions, I charge as needed.

Day to day its 80% in the summer and 90% in the winter. 100% whenever I think i will be putting more miles on that day

Regardless of the safety buffer built into the battery a lower percentage increases pack lifespan. Quick chatgpt answer here for an ER that drives 15k per year.

Charge to 100% daily (≈1.88% annual loss)
• After 10 years: 82.7% remaining → ~17.3% degraded → ~108.4 kWh usable
• After 20 years: 68.4% remaining → ~31.6% degraded → ~89.6 kWh usable

Charge to 90% daily (≈1.63% annual loss)
• After 10 years: 84.8% remaining → ~15.2% degraded → ~111.1 kWh usable
• After 20 years: 72.0% remaining → ~28.0% degraded → ~94.3 kWh usable

Charge to 80% daily (≈1.36% annual loss)
• After 10 years: 87.2% remaining → ~12.8% degraded → ~114.2 kWh usable
• After 20 years: 76.0% remaining → ~24.0% degraded → ~99.6 kWh usable

Daily to 85%. DCFC to 80% a few times per month. L2 charge to 100% about once per month. Truck is 3 years old with 45,000mi and SOH is 99%.

I let my Lightning drain all the way to 10-15% and time it so I'm home when it reaches the low state. Then charge it all the way to 90% unless I'm planning a trip north. If northbound, I charge it to 100% so I'm not white knuckles when I arrive at the cottage. I'll then repeat the strategy - let it drain while I'm tooling around town. When I'm ready for the trip south, it's charged to 100%.

I charge to 85% except when I need more. There is a downside to this though.

If you experience a battery module failure without a DTC or IPC message you will only discover it when you NEED the extra range. This happened to me last summer when I attempted to charge to 100% the night before a camping trip and was only able to get to 87%.

If you never charge above 85% you risk masking a module failure. I recommend charging to 100% occasionally for this reason.
