Charge Time Prediction on MFT Screen

[Hybridbear]

Our EVSE at home can charge the Focus Electric at the full 6.6 kW charge rate that it supports. The Fusion Energi only charges at 3.3 kW. The Focus Electric shows a charge time prediction on the MFT screen upon arriving home based on the 6.6 kW rate. The Fusion Energi also seems to get confused and display a charging time as if it could charge at 6.6 kW. MyFord Mobile never shows the erroneous prediction, but it does show on the MFT screen. See below:

 

Notice how it thinks it can charge to full from 3:00-3:31 am. This is how long it would take if it could charge at 6.6 kW. At 3.3 kW it will take about an hour since the current displayed SOC is 51%. MFM always shows a prediction that is slower than it actually takes, it currently shows 3:00-4:24 am as predicted charging time. The upper right corner of the display also correctly shows 1.4 hours as the predicted charge time.

 

Does anyone else who has an EVSE that is able to charge faster than 3.3 kW observe this? It's interesting to see this odd contradiction.

I don't use charge start times but I was watching the lower left corner as I drove.  The number appeared to be around half way between the 240 volt and 120 volt estimates.  When I got into EV+ range of home the number took a nose dive.  I have an EVSE capable of 10 kW (40 amps).  The number looks to be about 1/3 of reality so maybe the car remembers the maximum capability of the EVSE and uses that number.

 

 

 

After I started charging the numbers seem reasonable although the estimate is always high.  An empty battery takes 2:05 to fully charge.

 

 

Charging completed at 3:56 PM.
