An interesting thing happened to me on my recent trip. One of the chargers did not disengage properly and I was charged for many hours of charging and 179kWh's of power. My range on the next leg of trip was epic!
EA for their part made it right and refunded it.
But it got me thinking... particularly for chargers that charge by the kWh, how accurate are they? I mean there is no way that 179kWh was used since the plug was just resting in its cradle, not attached to the car. That implies that they might be determining the actual expenditure programmatically and while I'm not worried about EA programmatically lying (there is more than one irony here that is not lost on me), I am a little worried about perhaps smaller locations, for example, non ea ones, who's revenue might benefit doing so. Something akin to gas stations that pump 1 gallon of gas and reports 1.2 gallons for the sale. Alternatively, ones where the algorithm uses faulty inputs, in this case it seems time and kw being transferred was faulty. So while EA clearly believed me because they know I couldn't have used that much power... what if I called and made the same claim about 55kWh of power? Food for thought.
