Charging Overhead

I have a question relating to charging overhead costs that I asked in the Q&A page, but wasn't answered.

As I understand it, the Volt has a 16kWh battery, but keeps the pack between 30% and 80% charge at all times. Thus, 8kWh are required for the 40-mile all-electric-range. But how many kWh are required for charging in addition to the standard 8kWh needed to charge the pack?

I'm trying to form some simple calculations to determine the estimated cost of ownership of the Volt, and cost-per-charge has been a factor that I haven't quite nailed yet. I know it will be significantly more than 8kWh since the charging process isn't very efficient, but I don't know a realistic figure.

In other words…

Q: How many kWh (overhead) are 'lost' in the charging process?
