cost per mile math:
I drove 84 miles each way to and from the mountains yesterday/today. this took 40% SOC headed up, 20% SOC headed down.
the bZ4X pack is 71.4 kWh. let's call charger efficiency 90% (L2 EVSE at 240V). the 40% was refilled with off-peak MPEI electrons at 7 cents/kWh (ignoring fixed monthly service charges here, only marginal extra cost), and the 20% will be refilled starting in a few minutes using off-peak Xcel electrons at 12 cents/kWh.
that's $4.13 electricity cost. 2.46 cents/mile driven. acceptable.
