I know this item has been discussed a few different ways, but I wanted to try something a previous user posted in length about, as well as get some insight of my own. For reference, here is the length of the post I’m referring to: How I Recovered Half of my Battery's Lost Capacity
I fell down the rabbit hole about a week ago of checking my battery health with Tessie. Vehicle is a 2022 MYP. Took delivery in September. Car has about 4,000 miles currently. Used the Tessie app for a week, and it showed my battery health at 97.8% with 2.2% degradation. All of that came out to a decrease of about 10-13 miles (if you believe the max range is actually the EPA rated 303 miles). Upon the final Tessie evaluation, the max range on the car was 288 miles.
I spoke to a friend who also has a 2022 MYP that was delivered in March. This car has lost the same number of miles in range, despite having close to 15,000 miles. This got me thinking about battery calibration, which leads me back to the post I referenced at the top. Has my MYP actually decreased the same 10-13 miles in range as my friend, despite them having 11,000 more miles driven than me? There is only one way to find out. So, I am going to embark on what sounds like a long-term battery calibration.
My previous charging habits were pretty standard. I charged the car to 80% every night. Drove to work 5 days a week, 17 miles each way. I returned home with roughly 60-61% and charged the car back to 80%, following the Tesla rule of ABC (always be charging). I have only charged the vehicle to 100% 2-3 times in the nearly 3 months I have owned it.
Now, obviously I realize I haven’t lost near the range the original poster had. But I couldn’t help but think the only way my friend and I have the same range on the same vehicle despite them having driven 11,000 more miles is either 1) battery calibration or 2) somewhat rotten luck on my part.
I will post any updates as I go through this process, but my charging procedure now is pretty simple. I charge to 75% to start the week. Each day while at work, I take care not to open the Tesla app and let the car go into a deep sleep so the computer can get its readings. I then leave the car unplugged at night until I need to recharge, which typically happens on Wednesday or Thursday evening. Once I drive the car to around 12-15% battery, I let it sit unplugged for several hours with the app open, pinging the computer. I then let the car sleep before finally plugging it in to charge.
Full disclosure: I have only gone through this procedure fully once. I am now on my second week, and I will post any notable results as I get them. Any thoughts/comments/encouragement/insight is appreciated. I know that battery degradation typically levels off around 10%, and I know that it is inevitable. But I have also read about plenty of vehicles that have retained their max range at a much better rate than I am going (at least so it seems. Who knows? Maybe this is normal and I’m wasting my time). So, not sure how much is variance and how much is battery/computer calibration, but I am excited to find out.
