Yeah, on our 2011s there is a difference as Tom notes here: http://www.saxton.org/tom_saxton/2012/09/dcqc-soc.html" onclick="window.open(this.href);return false;rdhauser wrote:decided to stop at the Tahoma Market quick charger for a security charge. We thought we were just about through with the seventh bar (just below half a tank) and so selected 60% charge from the Blink quick charge options. That wasn't quite enough so I suspect there is some difference between what we track and what a charger gets from he car's system. We got home fine, but the last two or three miles were under the Low battery warning. Didn't ever see turtle, though. If we stop for a security charge in the future, I'm sure we'll take the time to get more charge than we need.
