Volt Traction Battery Reserve vs. Range

6192 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

Keep in mind the Gen II Volt by EPA numbers is between 5% (hwy) to 12% (city) more efficient than the Gen I Volt.
Also on the Gen I Volt EV range usable battery was about: The unused battery on the Gen I Volt was 6KWh.

2011 - 2012 - 10KWh
2013 - 2014 - 10.5KWh
2015 - 11.1KWh
