Actually as of April first off peak is now 7.7 cents/KWh. But that does not take into consideration variable delivery and transmission costs and GST.Depends on what time of day you charge.
I live in an area where HydroOne services ... so I charge in off-peak most of the time which is $0.087kWh. If you multiply this by the full size of the battery (let's say 10kWh for ease of maths, adjust to how much you drive and how large your battery is), you would get $0.87 for a full charge if that's what you're using per day.
It's only added about ~$35 a month to my electricity bill, which was way cheaper than what I have been paying for gas in my previous car, which was a Prius. And I drive a lot and sometimes even charge during on-peak.
If you charge one full battery every day, on off-peak power it would cost $1.82 for a gen1 (13kWh @ 14c) or $2.24 for gen2 (16kWh @ 14c).Sorry I have to disagree on that one. I pretty much fully deplete my battery daily and most I notice is about $30 a month max. Way cheaper than gas. I live in Ottawa.
