  1. Battery Capacity?

    Newcomers to GM-VOLT.COM (See here for FAQs)
    I now own a new 2018 Volt (left on the lot from last year). I know that the battery capacity will slowly fall over time, just like all other Lithium Ion batteries do. Is there a way to know from the normal Volt readouts what the current battery capacity is? I know in my Nissan LEAF there is a...
  2. GM deceiving us on Volt's battery degradation? No

    Li-Ion Battery, Charging, Mgmt System - Chevy Volt
    There's an interesting discussion in the comments section of this article: The idea is that our batteries are really degrading but we can't notice it because software is adjusting its algorithms with...
  3. Verify/Check battery capacity on a CPO 2012 Volt

    Generation 1 Volt (2011-2015)
    I am planning on purchasing a Volt and asked the dealer to give me any information about the battery health. I have the entire set of info in the following link: "" This is the global diagnostic system 2 data display. I am not savvy...
  4. Battery Capacity for Maryland Tax Credit

    Generation 2 Volt (2016-2020)
    For those from Maryland, when you or your dealer filled out the battery capacity field on the Excise Tax Credit form, did you/they use the total battery capacity of 18.4 KWh? I got a copy of my form today, and was surprised to see that the dealer listed the battery capacity as 13.5 KWh. I...
  5. Bolt's Battery Capacity?

    Chevy Bolt EV Discussion, News, Reviews & Events
    There is an interesting debate about the BOLT's battery capacity! The author, Francois Boucher thinks it will be over 60 kWh ... his deductions and logic is interesting, but I personnally think it will be around 50 kWh. I'm at CES Las Vegas right now ... impossible to obtain that important...
  6. Just set a new all EV record with my Volt after 48,000 miles!

    Newcomers to GM-VOLT.COM (See here for FAQs)
    So, how good is GM's battery technology? Well, just today I exceeded 46 miles on a single charge and beat my previous record of 45 miles. This is an old 2011 Volt with 48,000 miles on it! Clearly GM's battery technology is rock solid. Luv, Luv, Luv my Chevy Volt!!! Cheers, Eric J Edelen...
  7. Will GM offer EV Battery Mileage Software Upgrade?

    Software & Programming/Code - Chevy Volt
    Its my understanding the 2016 Volt will partially achieve better EV mileage by a software upgrade. Which I suspect means GM will allow more of the battery to be consumed. Can Version 1's owners, I am a 2014 owner, get such a software upgrade? PLEASE encourage GM to do so!!!
  8. Sudden mileage loss and worried -- Finally degraded battery?

    Problems, Driver Warnings or DTCs - Chevy Volt
    Sudden mileage loss and worried? Finally degraded battery? OK I dunno what's going on but I'm worried. -- My 12 Volt just started losing charge miles three days ago. Since I bought the car a few months ago this summer I have been consistently charging it to an excellent 40-43 miles before it...
  9. Can someone interpret this Volt battery capacity test report by D.O.E.?

    Chevy Volt General Discussion, News, and Events
    Can someone in laymen's terms just explain what the report is saying about battery capacity loss and the usable battery window? This is too technical for me. Are they saying they found the usable window shrinks when the total capacity shrinks or not? Thanks...

  11. Regeneration modes

    Li-Ion Battery, Charging, Mgmt System - Chevy Volt
    When in each of the regeneration modes, what is the range of charging output? Assuming an ever-lasting hill, running in 'B' mode, how long would it take to fully charge a Volt battery? Surely there's an engineer out there that would love to crunch these numbered!! :cool: Eric
  12. 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...
  13. Theoretical Max Battery Range?

    Generation 1 Volt (2011-2015)
    Hey folks, This morning traveling over the Altamont Pass here by Livermore, CA, I was re-generating the battery thanks to the massive downhills. When I left my house, my battery showed a range of 41 miles. When I ended up in downtown Livermore, the battery showed a range of 55 miles. It was...
  14. Nissan reaching out to Leaf owners good sign for all?

    Chevy Volt General Discussion, News, and Events
    It looks like Nissan is reaching out face to face with those battery capacity issue Leaf owners in Arizona....this would be a good sign for the industry in general..... MrEnergyCzar
