Re: What is your Average miles per kwh?

Mon Aug 24, 2015 11:32 am

In the summer, I had averaged 4.2 on the Ecopia LRR tires. I have since replaced them. They wore out far too quickly, plus I was leasing, so I bought cheapo non-LRR Fuzion tires. With these, I get about 3.6.

During the winter, I am currently at about 2.5. With the Ecopias, I got about 2.7. Most of my miles are spent shuttling the family from destination to destination, with the car cold-soaking at every stop. So the first trip of the day, preheating works just fine. But the rest require running the resistance heater (I have a pre-heat pump 2012 SV) to get the car back up to temperature.

I am still at 5.9 miles per kWh, and it briefly went up to 6.0. The other thing I do to save energy, is I coast in neutral whenever possible, and using D/B when I need to slow down. The Ecopias coast as well or better than any tires I have owned, which means that once you learn to ecodrive, you can get much longer range most of the time.

My commute is ~27 miles round trip, and I often charge once every 4 days.

IIRC, you are in Mass, right? What are you seeing for typical winter driving? What about during the deep freeze last February? I was barely getting 2.0 miles/kWh with the temperatures below 0F.

4.12 from wall, 4.65 from car. wall figure estimate based on guesses on efficiency from public charging sources. I have yet to determine a consistent reading from fast chargers which has led me to believe there isn't one and efficiency is controlled by SOC, batt temps, OAT, etc...

Yes, I am in Massachusetts, and I think the worst we saw last winter was ~402 Wh/mile, so 2.48 miles per kWh. We typically only use the heat when the windshield needs to be cleared; and use the seat heaters and the steering wheel heater when we are not warm enough in our winter clothing. Keep in mind, this is actual energy usage, and it uses a corrected distance - the dash meter is about 20-22% higher.

Here is my energy log: http://ecomodder.com/forum/em-fuel-log.php?vehicleid=8730

I have Nokian Hakka R2 winter tires which are as low rolling resistance as the stock Ecopia tires. They are also excellent winter tires, so slippage is minimized.

This is the dash meter, which is much higher than the actual number. I measure some of the charges, and I correct the odometer because the tires are smaller than those on the SL/SV models. The best charge I have gotten is ~196Wh/mile or ~5.1 miles / kWh.

Lifetime average since last October is 127.9 MPGe which is ~264 Wh/mile or 3.78 miles / kWh. Last 90 days is 158.3 MPGe which is ~213Wh / mile or 4.69 miles / kWh.

Again, here's my energy log: http://ecomodder.com/forum/em-fuel-log.php?vehicleid=8730

Boy, I thought I was doing well at 4.6 but I guess not. It's been 4.6 for the past 2.5 years.

5.5 miles per kwh average (from the dash) for the life of my Leaf (2011 with 43,000 miles, 50 months ownership). I reset the counter when I bought it and haven't touched it since then.
