  1. 2nd Gen Volt- no "engine running due to temperature" problem?

    Problems, Driver Warnings or DTCs - Gen2 Volt
    My 2016 Volt has never started the engine on its own as my 2011 did whenever it went below ~23 degrees Fahrenheit. My old Volt would cycle between battery and gas engine consistently when it got this cold. This is the first winter for the 2016 Volt, and it has never done this, despite driving...
  2. Scatter Plot of the Affect of Temperature on miles / kWh on my Morning Commute

    Chevy Volt General Discussion, News, and Events
    Back in January I started keeping track of the temperature and kWh used for my 19.1 mile commute to work. I excluded those days my son missed the bus and I had to drop him off at school and those days with adverse weather conditions. I always drive the same route, always go without climate...
  3. Range Drop in Wintertime for Gen 2

    Generation 2 Volt (2016-2020)
    We saw a brief weather drop down to about 50 degrees for a week or so. During this time, my range went from about 68 mi(when it was high 70s outside) to about 51mi. That's horrific! I'm hoping it doesn't get worse than that, but this is only the fall - can't imagine how bad it will get with...
  4. 4 Years of Data kWh/100 miles vs Average Monthly Temperature

    Chevy Volt General Discussion, News, and Events
    I have been keeping track for 4 years now the kWh / 100 miles from the OnStar monthly diagnostic emails. I have charted this using the monthly average temperature as reported by the Capital Weather Gang from the Washington Post. Since I rarely (very rarely) use climate control, the differences...
  5. 3.5 Years worth of OnStar Data Comparing temperature vs kWh/100 miles

    Chevy Volt General Discussion, News, and Events
    OnStar data is harvested from the monthly diagnostic emails. Average monthly temperature comes from The Capital Weather Gang of the Washington Post which posts the average monthly temperature for National Airport. I only drive locally, rarely use climate control. So, any differences can be...
  6. 3 Years of OnStar Data Comparing Effect of Temperature on EV Range

    Generation 1 Volt (2011-2015)
    Here are some charts with 3 years of OnStar data. I use the OnStar diagnostic emails that I receive monthly. Temperature is the average daily temperature reported by the Capital Weather Gang from the Washington Post. For EV range I am using the kWh / 100 miles and dividing that by 1250. I only...
  7. Outside temperature slow to update

    Chevy Volt General Discussion, News, and Events
    My 2013 Volt has always had a minor annoyance (and I do mean minor). The outside temperature reading on the display seems to take a long time to register the correct outside temperature. I notice it mainly when coming out of an underground parking garage, where it is usually around 85 degrees...
  8. 2 Years of OnStar kWh Data vs Average Daily Temperature

    Chevy Volt General Discussion, News, and Events
    The kWh/100 miles data was taken from the monthly OnStar diagnostic reports. Temperature data is from the Washington Post Capital Weather Gang. All months were 100% EV, except for Jan '12 and Feb '12 where I was a lowly 98.3% and 98.5% EV respectively. The outlier is Aug '13 with 23 kWh...
  9. Volt Intuition: Extreme Temperatures (for battery)

  10. Why was the ICE running on a Volt plugged into a 240 charger?

    Generation 1 Volt (2011-2015)
    Pulled my 2012 into one of the 8 charging stations at the San Jose Airport lot 5 yesterday at 4:30am temp was 41. Next to me was a 2013 plugged into a charger with its engine running and no one around. It shut off while i was walking to the terminal. By the look of the condensation from the...
  11. Some observations

    Li-Ion Battery, Charging, Mgmt System - Chevy Volt
    I'd recently complained about some fairly serious reduction in battery capacity, in my case from 10.5 kwh to 9.3 or so before CS kicks in. I was told it was "all those other factors like increased rolling resistance" and not the battery by many here. I just did a test that totally proves...
  12. In Cabin Fan Gone Rogue

    Software & Programming/Code - Chevy Volt
    I have a 2013 Volt. Yesterday while my wife was driving the car, the fan system suddenly went to full blast and all controls for the fan went dead. The car still ran. My wife drove the car into the garage and called me out before turning the car off. The fan controls on the right side of the...
  13. When Will The Gas Engine Run? Guide

    Generation 1 Volt (2011-2015)
    Asking "when will the Volt's gasoline powered ICE (internal combustion engine ) run?" is a simple question, but the answer will vary based on a number of conditions. Some people are concerned about carbon monoxide fumes in a closed garage, while others are curious about winter conditions or...
