Efficiency observation
Hi there, first time poster, soon to have my i-Pace delivered, but here's an observation from a long-time EV (Volt) owner based on the trip log you posted:
You have many many trips in a single day that are only a few minutes long. (Do you deliver pizzas? :smile2
The interior heater of the car uses a lot of battery power to heat the cabin, and on these very short trips, the heather is probably going at close to 100% power before you arrive at your destination. When you open the door, a lot of that heat spills out and the interior becomes cold again until the start of your next trip, which means the heater has to start all over again.
You can see that on all your short trips (< 10 mins) the kWh/100 mi efficiency is the worst. On your longer drives, the heat is retained, allowing the cabin heater to taper off and draw less power, resulting in better efficiency. In fact, it seems mostly true for your data that the longer your travel time, the more efficient your battery can be. This all makes sense in this light.
If you are brave to test this idea that it is your cabin heater causing the inefficiency, then try a few multiple short trip days with NO cabin heat. You can use the seat heater which helps a lot without using much power. Yes, you will be cold, but that is the price of the experiment! Depending on the outside temperature which may require battery conditioning regardless of cabin heat, my prediction is that your efficiency will immediately be much much higher.
Moral of the story: in winter, minimize cabin heat to the extent you are comfortable, and maximize heated seats. :grin2: In the summer, the story will be similar that you can get better range with no A/C, but the difference is not as significant since the A/C draws much less power than the heater. You spent a lot of money for the car, so be comfortable, but every bit of comfort has an impact!
I suspect many other posters on this forum don't make as many short trips as you every day in a cold climate, which may be why they aren't responding with the same conclusions as you.
