If I understand correctly Wh/mile is calculated based on the amount of energy coming from the battery.
Would it not be more fair using the amount of energy charged from the grid, because that is what we are paying for.

If I understand correctly Wh/mile is calculated based on the amount of energy coming from the battery.
Would it not be more fair using the amount of energy charged from the grid, because that is what we are paying for.

It is definitely interesting to know how much power is being drawn from the grid. Some people are doing so using a dedicated wall meter.

But I think it's worth keeping the energy used by the battery to drive (what people are reporting above) separate from the other two sources of energy use, namely charging losses and Vampire drain. Vampire drain in particular is something that does not depend on miles driven. It is also something that we are
hoping will be greatly reduced in future software releases. So I think it's good to keep these separate.

Based on the current averages, and based on what people are reporting for Vampire drain on the Vampire thread (and what I see myself)
total energy use (in kwh) to drive N miles in T days is, on average, approximately

Energy(N, T) = 1.08 * (.35 * N) + 3.5 * T

where the factor of 1.08 is an estimate of energy lost charging the battery and the 3.5 is the daily vampire drain which hopefully will be much reduced in a future release. The factor of .35 may also come down as we collect more data.

That's some mellow driving for a P85!

I was able to do sub 300 w/mile for 2 days of commuting (~100 miles) and it wasn't easy...

Correct, this is what the car is reporting for energy used. Charging losses are about 15%, plus there are vampire losses, which will vary based on how much you drive (for those who drive a lot, it would be a small percentage, for those who don't put many miles on their car, the vampire losses could be greater than the energy they use for driving).

Jeff - What does the .35 represent?

 

[Klaus]

Jeff - What does the .35 represent?

0.35 kWh per mile

 

[jweinstein]

0.35 kWh per mile

Thanks. Does the 1.08 assume an approximate 92% charging efficiency?

 

[Jeff Miller]

Thanks. Does the 1.08 assume an approximate 92% charging efficiency?

Yes. From what I've read/been told by Tesla the charging is roughly 92% efficient and discharging is also about 92% efficient (so a total of about 16% of the energy put into the battery is wasted) but the discharge losses are already accounted for in the Trip Meter screen, while the charging losses are not.

Update: 2015 miles, 357 wh/m, 85/19", Utah

 

[pbrulott]

my average after 3000 miles is 310 wh/mi (193 wh/km)

questions to all:

1) EPA rating consumption for th 85 kWh equates to 308 kWh/mi, what is the EPA consumption for the 60 kWH. Should I simply take the MPGe and make a rule of 3 (308 x 89 / 95 = 289 kWh/mi)?

2) What % of the battery is used at standard charge and max range charge? on a 60 kWh

3) The EPA rating quotes 35 kWh/100 miles for a 60 kWh (38 for a 85 kWh) and 208 miles for a 60 (265 miles for a 85)
When I convert this into kWh of energy I get 72.8 kWh in a 60 kWh battery???.... (35 kWh/100miles *208 miles = 72.8 kWh)
Does that correspond to grid energy consumption because it obviously doesn't match battery capacity?

My secret to a low number is lots of coasting. It is too bad that the regen system makes that somewhat difficult. I'm hoping that Tesla makes it easier to do in the future.

Interestingly, hypermiling a Tesla is not very different than a gasser.

Use the brakes as little as possible
Regen as little as possible
Avoid stops at the bottom of hills
Coast as often as you can
Crest a hill at as slow a speed as safe
Drive around hills and valleys rather than over/through them
Draft when safe
Slow is better than fast
Use climate control only when needed

I can guess, but would you mind telling us why you switched from 21" wheels to 19" wheels?
