 This isn't related to ham radio but I thought some might find it interesting...
-We've had our EV for a year now (and drove 18,500 km), so today I pulled the last 3 years of data from our BC Hydro account to see the impact of charging or EV at home.

 The numbers after ± signs in the table above are the standard deviations, which give a measure of how much the data fluctuates from the average (because of seasons and other factors).
-It seems that charging our EV increased our average monthly consumption by 230 kWh (30%).  To put this extra load in perspective, it's worth noting that the average difference between the maximum usage in the winter and the minimum usage in the winter is about 800 kWh.

-This extra 230 kWh a month costs roughly $35 a month, which translates to about $2.30 / 100 km.

 I also did a least square regression to a sine function and got similar numbers for the average:
