Amount of battery used for EV only driving

If the traction battery is less than 30% charged you won’t be able to engage EV mode and you get a message saying so. That’s 30% of the total traction battery not the EV portion.

 

This grahic I created helped me understand better.

 

Your 6.2kWh on L1 for a full charge is rather low. With L2 EVSE, I have read reports by others saying 6.0-6.3kWh for a full charge is common. But with an L1, most people report that the average is 6.5-6.8kWh. The reason L1 is higher than L2 is due to less conversion efficiency and a longer period of charge period (6 hrs for L1 vs 2 hr for L2) using fans and monitors for the charging.

The data and graph below are my own record on my 2021 PP for the monthly average of kWh of electricity drawn from the wall for a full charge. The number of kWh is extrapolated for 100% even when only partial SoC was charged. In fact, the partial charge extrapolated for 100% is more consistent than using the "real" 100% full charge since you can not assess the amount of SoC % used after the EV range is depleted. My 13 months average for a full charge is 6.67kWh.

Also, the use of "battery heater", "battery cooler", and "climate preconditioning" all use the traction battery kWh and increase the total kWh drawn from the wall but they do not end up stored in the traction battery when you unplug. In my record below, the Dec average was 7.22kWh which is higher than any other month. This is due to the fact that I had the "traction battery heater" function turned on. For subsequent months, I turned off the "battery heater" function and the number became consistent. I have never used the climate pre-conditioning or battery cooler functions.

There is some conversion loss, so not all the kWh from the wall ends up being used for the traction of the car. My estimation is that ~85% of the L1 wall charge or 5.65kWh (6.65kWhx85%) total is actually used for the EV mode portion of the traction SoC.
