Volt Traction Battery Reserve vs. Range

6209 Views 9 Replies 9 Participants Last post by  canehdian
I gather that Volt traction battery capacity has gone from 16.0 kWh (2011-12) to 16.5 kWh (2013-14) to 17.1 kWh (2015), and finally to 18.4 kWh (Gen 2). Therefore, there should be a small range difference in the various years of Gen 1 Volts, assuming that the traction battery is always drained to the some reserve capacity that is constant. However, that may not be the case.

Does anyone know (a) how much energy (kWh) remains in the traction battery when the system shows it is empty
and switches to the ICE and (b) if this reserve energy value has been the same, year by year, in Gen 1 Volts?

My 2014 was rated 10.7 usable...and FYI after nearly 4 years its down to about 10.2
How consistent is that figure? I mean, I "get" anywhere between 9.2 and 10.2 out of mine before it switches to CS mode, and that's largely seemingly dependent on ambient temperature (summer's better at extracting more kwh) and driving rate (slower driving wrings out more kwh than faster). Yesterday's was 9.6 because basically it did 38 out of 40 miles at about 60 MPH. A month ago, it got 9.9 because the 40 miles it got was city driving. Temperatures were about the same, number of miles about the same, amount on the discharge-o-meter was a half kwh different, to the same (built-in) depth of discharge.
