Yes, when your charge is complete open the FordPass app and tap the bottom blue banner. It’ll tell you how many kW added.

Maybe. Mine always shows N/A.

In FordPass click on Vehicle, Charging, Charge Logs. It will show %, not kWh. You have to do the math.

That might work, depending on how the car displays battery information as it ages.

Or install a kWh meter in the AC supply line. Then you will know exactly what was used.

Do you want to know what was delivered to the EVSE? Then the idea from @murphy62 is perfect. If you want to know what went into the car’s HV battery, you will need to dig a little deeper. I think that an OBDII dongle might be able to capture that information, but since I don’t yet have an MME I can’t verify.

My ChargePoint Home Flex provides a record of my charges and kWh usage in my online account. I can select anywhere from today to Lifetime. This provides the actual kWh dispensed, not what goes into the battery. The L2 charger is about 90% efficient, when I compare the ChargePoint number to the Ford reported number. DC chargers like EA will be 97% efficient.

Mine is always way off. For some reason when I plug in it immediately says it’s been charging for 4 hours, then when it’s done I’ve seen it as high as 350kwh… I don’t even know how it gets the numbers it does. I have a ChargePoint and it seems to be a little (ok a lot) more accurate.

Zombie thread! I didn't want to create another thread for the same basic topic. Does anyone know if one of these chargers will show kWh used, as well as, kWh delivered? Since EVSEs actually use about 10% more energy. If none of them have that functionality I will just get the meter @murphy62 linked above.

I am looking at one of these three:
ChargePoint Home Flex
ElectrifyHome HomeStation
Ford Connected Charge Station

I believe (and will be corrected if in error) the answer is no - they will monitor and report the output, not the input. For that you need to measure upstream.

The meter @murphy62 pointed to is one solution. My solution was an Emporia unit. Slightly more expensive, but I don't have to walk out to the garage and it provides time stamped data monitoring.

You're in luck, I'm a geek and have been tracking this... I have a Ford Connected Charger in my garage to charge 2 Mach-E's (Select and GT PE). I get charge delivered numbers from 3 sources, none match exactly, but two are usually close.

1. The Charge Log in FordPass app - shows kWh delivered. Sometime it misses the kWh but then I can extrapolate the kWh from the % charged and the battery capacity of that car. For example, from 28% to 90%, that's 62% charge. For 68kWh battery, that's 42.15kW. They are usually pretty close.
2. Connected Charger Insights - give's the power delivered by day. In FordPass, go to Account, then scroll down to Charge Station. Insights tab will show by Day, Week, Month & Year. The charge station usually reports on average about 13% more kWh than the Charge Logs. I think that's the efficiency, the difference is the power lost in the system for actual power absorbed into the battery pack. Or put it the other way around, the loss of energy delivered is about 12% due to inefficiencies.
3. Electric company online account reporting. Maybe your electric company provides similar data? I'm in eastern Iowa and have Alliant Energy, which shows Usage in monthly billing cycle, daily, and even hourly. I can clearly see the reported energy used during charge. I have compared that to extensive average of kW used during 12am to 5am with and without charging (set to start charging at 12am). I see it uses about 11.28kW per hour. That makes sense to about 47A used on average, 240V. I normally see about 1.4kW/h without charging, and 12.7kW/h charging, or about a rate of 11.3kWh charging.

The geek in me creates charts like this... hourly energy used for about 10 days... Clearly can see the spikes at 12midnight when charging the EV starts. I'm mostly doing this as challenge to lower our overall electric energy consumption - LED lights, variable speed pool pump, smart thermostats, etc. I have to take out the EV charging to get better ideas of lower electrical use not counting EV.
