100D's Battery Loss

[andrewxie]

Hi All,
I know this question has probably been discussed more than enough times, but I still couldn't find the answer I was looking for.

I picked up my 100D at the end of December 2018. I was mixing between charging at home and SC. It's now about 8,200km. Last week, I charged to 90% at the SC, it showed 400km. Later I charged couple times with home charger and SC; it consistently showed 403km at 90%.

I was wondering if the battery started to degradation. I didn't expect the loss range would be so soon though. What are your thoughts? When did your X battery start to loss range?

Ang comments would be much appreciated. Thank you!

I have a March 2017 X100D with 42,000 miles. My 100% charge when charging from home is now about 273. So about a 7% loss from the stated 295 mile range. Most of the loss (5-6%) occurred in the first year. The second year was only about 1-2 % more. I hope this helps.

Take it to 100% and then see what it says. This will allow the batteries to equalize well.
Some degradation is expected early, but small and should stabilize for many years

My 90% was 264 new, now after 2 years 23,000 miles 257

yes, that sounds right. Although I recall the initial claim was 300 miles and more recently restated to be 295. When my X was new, for the first few thousand miles, my 100% was 303.

Thank you all! I will charge it to 100% to see how much I've got. I will reply back here once I do.

Don't know. I always charge to 80%, unless on long trip, then to 100%

Yes, when my X was new I also got 303-304 miles at 100% but that was before a software update raised the rated kWh/m from about 331 to 339. I think they got some real world data and changed the formula in the software within a few months of my getting the car as it was one of the first 100kW batteries for the X. So I don’t use that number for my battery loss calculations anymore.
