80% to 90% charge daily will be just fine. Occasional charge to 100% will also be fine. Trying to maintain the battery SoC to 50-60% will do no good or no harm in terms of day to day driving. Instead, just charge to whatever and drive daily. Avoiding supercharging/fast charging will help more for your battery health.
That’s a good summery. To be clear, I’m sure you can charge anywhere within the “daily” percent every single day for months and you car will be great concidering the fact that you stuck to charging with the daily range.
Taking a road trip? Charging to “trip” (100%) if perfectly acceptable to use when going on a trip. Say you take long road trips 4, 5 maybe 6 times a year. That will be great as your car has the setting trip
Specifically for this purpose and it will not harm your battery.
Now if you drive 20 miles a day almost every day, do you NEED to charge to 90% everyday? No… you surely can and it won’t cause harm but you don’t NEED to. If you drive around 230 miles on many days a week do you NEED to charge to 90%? most likely yes, to be better prepared for extra destinations that were not planned.
If you charge to 50% everyday in hopes that your cars battery will be in a better place in the future, it very well may be. But in this case it’s okay because you are benefiting from getting more than enough daily range and perhaps you look to keep the car for a long time. But forcing yourself to chargers closer to 50% daily risking range just to reap the benefits of longevity is foolish I believe. The battery health benefits will be washed away by close attempts to make it to your destination or added supercharging (which in time using this a lot can be a negative for longevity of your battery).
In my case, I own my cars for around 8 years. Have for the part 3 cars. My goal is to hand my daughter my car as she will be able to drive in 8 years. I work close enough that 50% daily is more than enough for me. Two things can happen when the times comes and she wants to keep it; drives it until she is ready to purchase her own and the battery is able to get her to where she needs to go without worries. OR I pay for a new battery pack and wrap the car her preferred color and done. Or 3… she doesn’t want a Tesla, I buy her a new EV and upgrade my car.
My sister can drive 30 miles one day and next day 280 miles. No set time. At any given day. For her, 90% charge daily is what her car is set to.
In recap, enjoy your car, stay within “daily” range. Use “trip” if you need the added range for a long trip. And you will be golden!
