cegarbage Posted February 8, 2015 at 05:58 AM Report Share Posted February 8, 2015 at 05:58 AM On the Ford app under 'trends', it shows total kWh consumption for the month. Is that number solely from plugging in? I'm trying to determine how much kWh I have used from charging since I bought the car 3 months ago. Some days I charge the full 7 kWh, others half, sometimes two times a day. Is that data available anywhere? Quote Link to comment Share on other sites More sharing options...
murphy Posted February 8, 2015 at 12:07 PM Report Share Posted February 8, 2015 at 12:07 PM The only way to get that data is to install a kWh meter that records only what is used by the car. Charging is no where near 100% efficient. The most my car has ever reported gaining is 5.6 kWh. In that case the external meter measured 6.8 kWh. This is the one that I use with my 240 volt charger. http://www.ekmmetering.com/basic-kwh-meter-100a-120-240-volt-3-wire-60hz-ekm-25ids.html If you get it also order the mounting rail. If you are using the 120 volt charger that came with the car a Kill-A-Watt plug in meter will work.The downside for this one is it loses its reading when disconnected from power while the 240 volt one will maintain its reading, in the absense of power, for 10 years.

Doug0716 Posted February 8, 2015 at 03:50 PM Report Share Posted February 8, 2015 at 03:50 PM Hah, that's the exact meter that this one uses (so really this just adds WiFi and phone app support for some phones, and is $200 bucks... yikes!)http://www.emotorwerks.com/products/online-store/product/show/205-wattbox-200 Quote Link to comment Share on other sites More sharing options...
larryh Posted February 8, 2015 at 05:18 PM Report Share Posted February 8, 2015 at 05:18 PM (edited) You can approximate the amount of energy used by the charger. For the 240 V charger, approximately 82% from the energy from the wall is stored in the HVB. For the 120 V charger, it is approximately 72%. Use one of the trip odometers to keep track of the amount of energy consumed by the car. Then divide by 82% or 72% depending on the charger to determine the kWh consumed from the power company. Note that the car does not keep track of energy consumed for preconditioning or charging the 12 V battery.

cegarbage Posted February 9, 2015 at 05:34 PM Author Report Share Posted February 9, 2015 at 05:34 PM It looks like these need to be installed by an electrician. That's probably overkill in terms of cost v. benefit.What is kWh "total consumption" on "trends" within the ford mobile app telling me?

Doug0716 Posted February 9, 2015 at 11:53 PM Report Share Posted February 9, 2015 at 11:53 PM Oh it's definitely overkill cost vs benefit because there's no financial benefit but it's the only way to get the number acurately. Murphy provided information on how to calculate a rough estimate (1.21 * (kWh consumed - kWh generated)) based on the trip meter. Only Ford can answer the question, and they might but I would take it as literal as possible. I would guess it is the total kWh consumed, including generated from brakes and such. Unless you have a trip meter that you've never reset then I don't think there's anyplace to see the kWh re-charged or consumed, but I don't know what's in the app because it's never worked on my phone :-/ Quote Link to comment Share on other sites More sharing options...

That would represent the actual KW used by the vehicle. Including the regen would not represent a true use of electric, since the energy was not created from the external source. But as you say, only Ford could tell us for sure. I also say that beacause the MPGe would be skewed if they included the regen in there - and it would be lower, which Ford is trying to avoid. In some ways it doesn't matter, because whatever you regenrate is just energy that will not have to be recharged at the next plug in charge. But it does affect MPGe. I use the meter to determine my MPGe. Quote Link to comment Share on other sites More sharing options...
openair Posted February 10, 2015 at 05:18 PM Report Share Posted February 10, 2015 at 05:18 PM (edited) The trip meter in my 2014 fusion energi and on my ford mobile only reports net draw from the battery. It does not include any regen or any generated by the ICE turning. This is evident under certain driving conditions. For example an all ev later trip. Since the (monthly) totals are most likely calculated from the same trip data they also likely only include draw to charge the battery.. Obviously does not including any charging inefficiency loss.

larryh Posted February 10, 2015 at 08:26 PM Report Share Posted February 10, 2015 at 08:26 PM (edited) During regen, the kWh meter on the trip odometer runs backwards. You can observe this during a long downhill grade. Regen is recyling plug-in energy for later reuse. You used plug-in energy to get up the hill, now you reclaim some of that energy back when going down the hill. Similarly, you use plug-in energy to accelerate the car up to speed. Regen reclaims some of that energy when you stop--the kWh meter runs backwards.

openair Posted February 10, 2015 at 10:00 PM Report Share Posted February 10, 2015 at 10:00 PM During regen, the kWh meter on the trip odometer runs backwards. While that may be true of the 2013 i do not think it is true of the 2014. Possibly changed along with some of the other changes made to the trip meters between 2013 and 2014.

Possibly changed along with some of the other changes made to the trip meters between 2013 and 2014. Have you checked this? It's pretty easy. Reset your trip meter about a mile before exiting the freeway. Watch your trip meter when braking down a long freeway ramp from 65 down to 0. You should see the kWh decrease. Your MPGe should also increase (assuming that the data is small enough to see a meaningful change). Quote Link to comment Share on other sites More sharing options...
openair Posted February 10, 2015 at 10:27 PM Report Share Posted February 10, 2015 at 10:27 PM (edited) I have not. I could be wrong. I'll try that omw into work tomorrow. But I don't recall ever seeing this and trip data on MFM doesn't seem to support it. Just this past sunday I have a trip with 5.7kwh and 1.5 regen km. If the trip were counting backwards during that 1.5 regen km I actually pulled closer to 6kwh. Which shouldn't be possible.

Hybridbear Posted February 11, 2015 at 10:18 PM Report Share Posted February 11, 2015 at 10:18 PM The data shown in MFM is starting ETE minus ending ETE. ETE = Energy to Empty, i.e. the amount of energy stored in the HVB. If you are traveling at 60 MPH with 4.0 kWh stored in the HVB & 10.0 kWh showing used on your trip 1 and then you stop and then are traveling 0 MPH with 4.2 kWh stored in the HVB, then the trip meter kWh used should drop from 10.0 kWh to 9.8 kWh.

openair Posted February 11, 2015 at 11:13 PM Report Share Posted February 11, 2015 at 11:13 PM Yep, I stand corrected. The kWh trip counts backwards for both regenerative breaking and charge gained from the ice turning. Maybe like some logs on mfm the example I gave above isn't very accurate.

I was speaking of that KWH reading. Quote Link to comment Share on other sites More sharing options...
