Congratulations on your Audi Prestige! I'm assuming your are in DC? In the summer you'd be working with close to the 230 max range EPA at 100% charge. If you charge to 80% max charge for everyday use as recommended by Audi, you are talking 184mi. Factor in miles lost due to A/C, driving style, etc, you would probably get one 80 mi trip out of a single 80% charge. Note that in the winter, your might lose 15% or so of battery capacity. That still works, but cuts your margin a bit. So, it looks like you'd need to make your way to your L2 charger every other day. The Audi does not suffer from any "phantom drain". That is, what you put into the battery stays there until you take it out, so charging it and then parking it on the street would not be a problem (well, except that it IS DC. My son lives there so I know what that can mean!) Will you need to reserve another 20 mi or so just for driving around to find a parking spot?
