Ampera aka IGOR
I use Torque Pro with an OBD to read things from the Ampera. Normally when the car is fully charged I have been seeing a battery charge of 83.5% with it occasionally showing 84.1%. Today on the way to work I had 2 miles remaining and about 2 to go with a couple of junction acceleration points. I hate driving the car a short distance with the engine kicked in so I thought I would try Mountain mode to give the battery a wee boost for moving the car to the charger at lunchtime as opposed to the 1 mile on the engine. After it had been running for a few minutes the range was showing '0', kind of disappointed that I had not had it running for long enough but anyway went to move it back to normal and noticed that 'Hold' was not available, probably due to the low range. So I went to 'Normal' and found I had 6 miles range, enough to get to work and also move to the charger midday. Come time to head home first thing I noticed was the range was at 50 miles, normally only 48 for the last week or so but the battery charge was now up to 87.1%. Back home tonight, charged up in town and the battery capacity is still showing 87.1% and a range of 50 miles.
