Still a problem I think for the cost of an EV. We the people are accustomed to gas engined cars and car easily translate the EPA economy numbers into what we see in the real world and into cost. Don't know about you guys but I know exactly how much I spend on gas for our cars from the credit card slips.
With an EV such as the Leaf all we see is the household electricity bill going up but unless the dedicated car charger has a meter in it ( do they? they should) we don't know if the extra is the car or whether someone left the lights on,the freezer is malfunctioning or the clothes dryer used more than usual.
Further there is that battery problem. As the evs, so far anyway, don't have much power to spare, every use of the ac,heater, lights etc lessens the range, doesn't matter in a gas car as the nearest fill up is usually close, quick and always available but on an EV it is important. So should Ev numbers be posted with ac on/ac off lights on/lights off corrections?
