Energy Use Question.......

1209 Views 9 Replies 7 Participants Last post by  canehdian
I leave my Volt plugged in when not in use. Does anyone know about how much energy is being used AFTER my Volt is fully charged, but being left plugged in? I assume this might vary some depending upon the temp inside my garage, but assuming the temp is about 70 degrees most of the time, what do you think? Seems like when someone asks me what it really costs to run my car on electric only I would need to account for any power consumption by the car while being plugged in.

My 2014 GM L1 EVSE (Clipper Creek OEM) uses 2W at idle. The 2017's could be lower, but I haven't heard of any actual measurements. If you pay $0.11 per KWHr, that's $1 per watt per year (good rule of thumb), or $2 per year for the EVSE plugged in 24/7. Remember that standard outlets are not designed to be plugged into every day, they will loosen up over time, requiring replacement.
