Charging history and percentages

[aerodyne]

Yup. This is what mine says. Based on this. I will leave it at 70 and see how it goes. Thanks all!

Another data point for the older cars. Years ago Elon responded to a tweet and stated that the best storage SoC was 50-62% and operating SoC mostly between 30 to 70%, if you wanted the pack to last 15 years or so.

By following this you might get slightly less degradation than others, but it won't necessarily protect you from a sudden pack failure.

Ask me how I know...

Nick, I think the only “to what percentage should I charge” answer which is pretty much universally accepted is “don’t charge to 100% unless you’re going to start driving the moment charging is complete.” I could be wrong, but I think it’s close to universally accepted that it’s not good for the battery to let it sit at 100%.

I have 240k miles on my 2015 85D and charge to 90% at home for my commute in one direction, Supercharging at the other end. At home I set my Amp rate such that it will finish just before it’s time to head out.

I usually drive in an hour or so after the charging is completed. I don't have charging at home anymore so I usually go between 80 to 100 percent charge. This is mostly at work and I alternate between the Tesla and the Bolt. Recently on a trip to San Diego and back I got exactly 296 miles and I could have easily gone a few miles more.

What year? What model? What happened? Was it covered still?

Glad it was covered. Assuming no problems since?

Car was sold before the failure. I have not heard of any problems, but the new owner is a little sore about the drop in value due to price cuts.
