I'm still learning a lot about the world of electric cars, volts, amps, watts, etc., so bare with me...
From my reading here, the car can use approximately 21kWh from 100% to dead-ish.
Assuming the above is true and I didn't use a single drop of electricity at my home that entire day outside of charging my car, would my daily usage (as observed by my online SmartMeter info) show 21kWh of usage? Or, in order to absorb 21kWh into the traction battery, it actually will draw more - like 22/23/24/etc.?
The reason I ask is because on days I don't charge (yes, I sometimes charge every other or every two days) I typically use between 5 and 7 kWh. Add to that the charging of the car to 80% on most charging events and to 100% once a week or so, I'm seeing higher kWh readings from the SmartMeter than I'd expect the car is taking in: One day has about 29 kWh and another has 36 kWh.
I'm trying to understand if the electricity usage is actually more than the amount taken in by the battery. This way it helps me to explain my energy usage a little better.
Additional thoughts... If electricity is wasted during charging, is a higher percentage of electricity wasted when charging from 80% to 100% than from <80% to 80%?
