Not maintaining it to extend its useful life may be less green and/or more expensive to the owner. I think when it gets cold/hot it should be aware of it. It can absolutely not be charging batteries that are frozen or letting them fry I would think. That will take power. When at 68 oF that draw should be close to nothing one would think.
2.1-2.8. On my daily commute depending If I have fun or not, 15 miles, 50 MPH average, heat on 68, seat and wheel on too. I have seen 3.1 with heat on 65. 16-22F. The fully loaded 150 mile road trip to grandma’s (over the river and through the highway) is this PM, but it will be in the 20’s.
No, the GOM is not interesting. Mine is telling me my ER RWD only has a 200 mile range even though the tripometer is showing an average of 3.5 mi/kwh over the last 175 miles. What mi/kwh are you getting on drives longer than 25 miles?
I think the only easy way to answer the the question would be to put an energy monitor on the 240V line that feeds your charge station (EVSE). There are many types, the easiest would be one that uses clamp on AC current meters. I have both the chargepoint flex with reporting and a whole home sense energy monitor. The chargepoint reporting is probably not sensitive enough to show very low power, but more likely it just comes on once in a while for a short period of time at some few kW, and that would show, but not with much time resolution. Something like the sense has to find and categorize each load by itself. I've given some thought at times to buying another one to be able to place it on just one load at a time, such as the charge station. That has the granularity (excellent resolution in time and power) for sure to answer your question, but they cost some thing like $300, maybe less on sale, each. There are inexpensive imports that can do similar monitoring, you would have to research them.My original question was not about battery loss while idle. It was about additional power usage while plugged in but not actively charging. recently every time I turn off the car I see a message saying
so why would it be important if it were not going to use energy? In addition, while it is sitting idle I’m my garage there is the sound of some sort of motor running.
So it is definitely using some electricity. Just a question of how much. And since my car spends 12-24 hours a day plugged in, that could add up. Both of the graphs offered display kilowatts, but even a small extra 40 watts for an average 18 hours per day is 21 kWh per month. Not going to break the bank, but I would just like to know.
That is what I did answer and it depends what the conditions are. Not sure what your electricity price is but we put 10,000 km on it in the last 10 - 11 months (beginning of February) and we see about $10/month on the bill. It is a whole lot less than at the gas pumps That is if it is maintaining itself or not. You can get a charger to monitor that all for you if you are so inclined.My original question was not about battery loss while idle.

I've only seen that message once so far. I showed how mine charges and then stops almost immediately. I will see what it does in Jan and Feb.My original question was not about battery loss while idle.

The other aspect is that the EVSE is mostly likely sitting idle most of the time. The noises you hear are mostly 12V (low voltage battery (LVB)) operated equipment cycling on and off. Eventually, if not driven frequently, MME will charge the 12V battery while parked by turning on the DC/DC converter, which will slightly drain the traction battery. The EVSE will likely supply some 240V AC power at that point if MME is plugged in.My original question was not about battery loss while idle.

I'm not sure what other explanation you wanted. Like I said, it tells you that once external temperatures are < 32F, just in case your pack temperature falls below that temperature. Li-ion cells cannot be charged when they fall below freezing. Since the battery pack has a large thermal mass, it'll take a while for the pack to drop below freezing, so driving the car daily probably won't cause it to heat the pack.My original question was not about battery loss while idle.

2.5 mi/kWh since new, 2350 miles. Winter probably average of 28-32F in Maine.
You can get another set of Sense clamp sensors for $50 to monitor branch circuits with your existing monitor.
That would be great, but it looks like a later model, sense flex. Even it could be done with the base model, mine is already using the aux input for the additional two clamps for the sense solar system monitor, bummer.
yes, to first order. Certainly shows gross power and total energy. The time from point to point is usually 15 or 30 minutes. Most charger logs probably (?) would not pick up a short time use. That is the question, does MME only take long intervals of use, or does it take short sips from time to time? Would a 3 minute use show up on a regular charger log? A high resolution (time and power) logger would show a short use for sure.
They recommend that it be plugged in for at least a couple of reasons, probably more. First, as said, if it gets crazy hot or cold, the Mach-E might do some battery warming or cooling. Second, if you have preconditioning times set to leave for work, for example, if it’s plugged in, it can recoup most of the power used for that from the wall connector. Last, it’s just a better user experience to know that every time you walk out to the car, you have a ‘full tank‘ ready to go. It’s a poor experience to walk out in an emergency and find you only have 20% in the battery and then you have to hope you’re near a DC fast charger, etc. Leaving it plugged in when home avoids all these issues.
