How much charge should I add daily?I travel 35 miles per day so currently I charge up to 50 miles every day

Well we can’t go by what you recommend after all your parked in a no parking zone!!!?

No kidding - the location of the charge port and distance to the charger makes is tough not to take up 2 spaces for 1 charger. That charger was in Orange County, CA.

Here's another Tesla spot I am taking up a handicap & no parking spot to avoid taking an additional space this time in Los Angeles County, CA.

Glad I do have a handicap placard for legality. ?

I drive the same distance and need to charge once a week.

At home, I charge to 100%.
On the road, I charge to 90%.

Tesla Superchargers are a game changer for me!

Your Mach-E thinks it’s a pickup!

Currently, I drive 35 miles per day. I read that it’s best to charge every day just enough to get you by so I charge the car up to 50 miles every day. Is this the right way to go?

No point in filling the batteries right up, you're just lugging more weight around

You really don't drive enough to warrant daily charging. I charge to 90% and run it down to 20-30% before charging. If you want to go easier on the battery set your charge limit lower, maybe 80%.

Warrant charging daily? Why? So much thought into charging. Plug it in when you get home. Whether i need 1% or 100%. why wait? One joy of an ev is I have a full tank whenever I leave the house. Then ready to drive 3 miles to store, 30 miles to visit, or 300 miles for fun. I charge to 80% daily. That way if I drive 0 miles car is fine, even an unexpected trip at least have 80% to start. The only thought is if I KNOW I am taking a long road trip i charge to 100%. (Or if it is free I charge to 100%)

Didn't think about all the extra weight of electrons! Thought low mileage cause I drive fast. It is all the extra weight I am always lugging around!

NMC batteries like it best at about 50% state of charge and prefer small % charges to reduce heat and microcracking within the battery crystal structure. Ford recommends 90% because they want to show a good range (reduces range anxiety in customers). If you can charge at work and home every work day, that would be best for the battery no matter what your stop charging level is (60%, 70%, 80%, etc.). I keep my MME at 80% because that is my comfort level, I might decide to go somewhere farther away on a whim and don't want to wait for charging. I plug it in every time I get home and at any location I'm visiting that has a free level 2 charger available.

After a bazillion 'what should I charge to' threads, this is the first time I've seen this strategy. I'm throwing zero shade, because how else do you find out except by asking.

No, I feel that's too low in that battery's state of charge. I would set it to charge to 60% and plug in every other day. If you want less wear and tear on your charging connector and charging handle, charge up to 90% and plug in when less than 30%.

I drive less than you and have my charge limit set to 80%. I also charge at 120v (standard plug) since I don't need 240v level charging. Saved me installing a higher voltage and gives the 12v battery a longer charge (12v only charges when car is on or when actively charging).

Your tiny 12v battery could benefit from overnight 120v charging, and since it's possible you'd get an OTA update while it's charging it's more likely to succeed with a full 12v battery.

All of the above is of course assuming you understand your car will work perfectly fine with whatever charge/don't charge solution you decide on. This is just an OCD optimization discussion we're all having. Forums are great for nitpicking, but your car is engineered to work well in all situations.

What I’m tracking from all the numerous threads on charging strategy. Avoid the harmful behaviors of long term repetitive storage at extreme SOC and temperatures. Even if you don’t, the battery will still make it well past the warranty. Next major factor is battery age. After that , the details of any charging strategy probably aren’t going to impact long term SOH enough to deal with the stress of worrying about it. Additionally, even if you try to super optimize.. they data doesn’t exist or is probably too noisy to make any conclusions. But if it makes you happy , go ahead and try.

Exactly true. 90% isn't best for the battery (even if true SOC is 85%), but it's a compromise between minimal extra degradation and feeling reasonable to customers. If they told you that 50% was best, people would complain even more.

If you are charging at home, find out the cheapest times to charge then set your charging time program, set max to 90% as per the manual and set your departure time.
This way you save money, cool your battery after driving, have plenty of charge that won't affect the battery health and warm your battery for the next drive.
So, Park it, plug it and forget it!

Even if ypu do everything wrong battery should be good 150k-200k. Do everything right maybe 200k - 300k. Car will be gone long before battery needs replacing. Not worth stress of all these weird charging strategy. It's a car it will be fine. Drive it, drive trough car wash, enjoy the car.

There was a study done that was posted here in another thread. The people conducting study found that it’s best to never charge over 80% and don’t let it drain below 20-30%. They found the maximum battery life comes when you do several 10-15% charges. Of course that is not practical for many. The study further concluded that DCFC does wear down the Barrett faster than level 1 and level 2 charging, but ultimately, their conclusion was don’t worry about it. The battery will outlive the car in almost all cases, provided the battery is not defective. Sure, they are likely looking at a 10 year life, but till, the difference was insignificant when you compare the burden of trying to stick to a strict charging schedule.

what I did was to install a 40amp level 2 charger at home. I set the car’s location based charging so that if charging at home, it charges to 85%, and we simply plug it in every night. This buys us the convenience of auto start every morning. It brings the interior temperature to where we want it, and it does not draw battery to do that. By the time my wife leaves for work, the battery is ready to go and the car is nice a toast (or chilled).

I used to go 80% to 20%, but after watching this video, I go 80% to 60% for everyday driving and don’t sweat it when I can’t.
