Lifetime Average Wh/mi

This site may earn commission on affiliate links.
At 50k miles and almost 3 yrs, I'm at 296 Wh/mi lifetime. I also track my total energy usage from the wall, and that number converts to 363 Wh/mi lifetime, which includes all efficiency losses.
That is revealing.
I'm sure if I had such usage data, it'd be much worse; since it'd include winter time pre-heating as well as battery heating as it starts charging.

My life-time shows 297. Four and a half years, 119k miles.

After 25 months of ownership here are my P90DL's numbers

Current Month March 2018
Distance in Miles = 549
Total energy kWh = 198
Avg energy / Mile in Wh/m = 359
Avg Temp 36.8 (from TeslaFi)

Lifetime (25 Months)
Distance in Miles = 27,427
Total energy kWh = 8967
Avg energy / Mile in Wh/m = 327

This month's data reflects continuing cold weather driving with use of cabin heater, heated seats and steering wheel as well as defrosters and no use of air conditioning. Use of the S this month was less than normal. Battery degradation since new is holding at about 3% at 90% charge (241 new vs 235 now). Winter tires have been installed (Micheline MXM4 19" and Tesla 10 spoke wheels). Normal daily charge level of battery is set to 60% due to my daily use case.

Range Mode OFF entire month and on firmware = 2018.6.1 641efac since 3/5/18.

~ 1400 miles, been on two trips where we averaged about 70 mph. 335 Wh/m. It's also been cold, around 20F during these trips.

I'm looking forward to warmer weather as our primary use case is a 280 mile drive that should be doable when it's not so cold. Or so I've been told.
 
After 26 months of ownership here are my P90DL's numbers

Current Month May 2018
Distance in Miles = 1,513
Total energy kWh = 475
Avg energy / Mile in Wh/m = 314
Avg Temp 65.5 F (from TeslaFi)

Lifetime (26 Months)
Distance in Miles = 28,926
Total energy kWh = 9442
Avg energy / Mile in Wh/m = 326

This month's data reflects mild weather driving without use of cabin heater, heated seats and steering wheel as well as defrosters and slight use of air conditioning. Use of the S this month was more than normal. Battery degradation since new is holding at about 3% at 90% charge (241 new vs 235 now). Winter tires have been installed (Micheline MXM4 19" and Tesla 10 spoke wheels). Normal daily charge level of battery is set to 60% due to my daily use case.

Range Mode OFF entire month and on firmware = 2018.14.2 since 4/20/18.
 
124,071 miles, 290Wh/m

Lifetime average hit 291, the weather finally turned around and it dropped already.

What happened those last 3 minutes, @jerry33? I don't think I've ever seen a number like that on your images.
Stopped at HomeDepot on the way home. A trip of only 0.6 miles in 36 degree weather with the A/C on always has the high startup number (I was surprised it wasn't higher because the first number after startup can be over 1000.)
