I have had a strange drop in range on my late 2016 90D Model S. I purchased this car used from a third party in January 2019. Had been daily driving it plus many long trips since purchasing. On my long trips I would usually charge to about 90 to 98% prior to leaving and could easily make 200+ miles, even in cold winter weather, on hilly terrain, on snow tires, and lots of highway driving 80+ mph.
I was traveling out-of-town in the month of April and so I left the car in my garage, plugged in and the charge limit set to 80%. I was gone about 3 weeks and when I returned the car was at 66% or there abouts, can't remember exactly. I thought was strange since it was plugged in the whole time it doesn't seem to have just stayed at the 80% charge limit. Didn't think much of it as the time.
I went about my normal daily driving with charging at night time to 80% for normal daily driving or up to about 95% if I was going on a longer trip (my usual long trip is about 200 or so miles each way which I do most weekend). I was not getting even close to the same range as I would before. This is in spring weather without the need for heating or air conditioner and on new summer tires.
For example on my usual 200 mile trip I would arrive with anywhere between 10-15% charge remaining but now I was unable to make it on my standard 95% charge. I started to check my range by charging up near full and seeing how much mileage I could get without recharging and these are the results:
FIRST TIME:
Charged to 90%, computer gave me 255 miles range
After driving157 miles only 5% charge left (and computer gave 15 miles range remaining)
Trip computer calculated 52kwh used at 332wh/mi
SECOND TIME
Charged to 98%, computer gave me 274mi range
After driving 176 miles with only 3% charge left (and computer gave me 9 miles range remaining)
Trip computer calculated 58kwh used at 330wh/mi
THIRD TIME
Charged to 94% and computer gave me 262 miles range
After driving 153 miles and 15% charge left (and computer gave me 43 miles range remaining)
Trip computer calcuated 48kwh used at 323wh/mi
Based on these data I only seem to be getting about 61kwh out of my 90kwh battery. Vehicle has 36k miles on the odometer. Had much better range before I parked it for three weeks..plugged in.
Any idea what is going on?
