  1. Battery Charge Indicator problem after Hybrid Powertrain Control Module 2 (HPCM2)

    Generation 1 Volt (2011-2015)
    Hello Volt family, I took my 2013 volt for the above recall last year and the next day the charge indicator was showing 60mi charge, which at first made me really happy, but of course, I realized that was impossible... I called the dealer and they asked me to take the vehicle back only to tell...
  2. 2011 Volt. 12V battery charging problem

    Newcomers to GM-VOLT.COM (See here for FAQs)
    Hi All, Happy to join the forum. Looking forward to interacting with other volt users especially as there is no volt service outlet where I am located. I am particularly looking forward to reviving my 2011 volt which is currently unable to charge the 12v battery. I have replaced the APM but...
  3. Full Battery charge 2018 volt

    Li-Ion Battery, Charging, Mgmt System - Chevy Volt
    We purchased a 2018 Volt on Nov 18 with 5 miles . Back in shop on Nov 20 with 12 miles for bad battery cell #3 (1 of 3 batteries in car). Back in shop on Nov 30 with 100 miles for bad battery cell #2. We are dealing with Chevy corporate and BBB right now. My question is how many miles do...
  4. Battery Health - Can Regenerative Braking Overcharge a Full SOC Battery?

    Care, Maintenance & Service - Gen2 Volt
    I've had my new 2017 Volt for several weeks now and I've run into a slight concern. I live at the top of a fairly sizable hill/mountain, which means that when I leave home, I start my trip with a good run of driving in L and/or with light to moderate use of the break pedal on the way down. (It's...
  5. Battery overcharging

    Problems, Driver Warnings or DTCs - Gen2 Volt
    On hot days, my Volt will indicate up to 65 miles on plugged-in battery charge. Is this tough on the battery? Thanks
  6. 2015 Battery Charge Max Now Indicates 60 Miles Max (!)

    Chevy Volt General Discussion, News, and Events
    When overnight charging my Volt, I typically see between 35-40 miles of maximum battery charge. After charging overnight this past Sunday, I was greeted by a "60 miles" battery charge reading, which continues to persist. Did Chevy upgrade the Volt's operating system software, to give use all a...
  7. no charge & check engine light on

    Generation 1 Volt (2011-2015)
    Weird event this morning. I went out to run an errand so I unplugged the car, got in and backed out of the garage before I noticed my battery level was at zero, my engine was running and the check engine light was on. Last night I had used up the battery so as I got home I did a temporary...
  8. Parking Days Without Charging

    Problems, Driver Warnings or DTCs - Chevy Volt
    Prospective Volt buyer. I drive frequently for multi-day trips (sometimes as much as a week or two), during which time I park my car and don't drive it. There wouldn't be charging available at the parking garage I leave the car at. The Chevy dealer told me that if I drove to the garage (arriving...
  9. 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...
  10. Is my fully charged battery fully charged?

    Li-Ion Battery, Charging, Mgmt System - Chevy Volt
    Ive had my 2013 volt for about a month now. When I charge it using the 120v charger, it typically shows 31-33 miles of range. ( it hasn't been above freezing since I bought the car!). I live at the top of a long hill. When i go down the hill , regen braking in low most of the way, i end up at...
  11. Question about Power Flow Screen (Green Bars)

    Generation 1 Volt (2011-2015)
    This may have been asked before but can't find a post on the topic. When I start the morning with a fresh full charge the distance remaining is 44 miles. The power flow screen displays all green bars/full charge. The next 5 miles are down hill so I gain 7 miles... so now there are 51 miles...
  12. SOLVED - Charging problem at public stations

    Electric Vehicle Batteries & Plug-In Charging
    I thought I would follow up with the Volt community about charging problems I was having at public (Chargepoint) charging stations. When I first got my 2013 volt it was charging at home and at public stations just fine. After about two weeks it stopped charging at public stations but was...
  13. Determining battery charge more accurately

  14. How to get meaningful energy efficiency data form a Volt?

    Generation 1 Volt (2011-2015)
    I'm trying to find the true miles per energy input (as kWh or gallons of gas) efficiency data vor my new Volt. Can you help checking whether this assessment is correct? It does not seem to match the info displayed on voltstats.net or myvolt.com The Volt itself prominently shows the MPG measure...
  15. The battery performance deficit disorder

    Chevy Volt Engineering and Design
    http://gigaom.com/cleantech/the-battery-performance-deficit-disorder/ In "The battery performance deficit disorder" Tom Murphy (an associate professor of physics at the University of California, San Diego) attacks the viability of battery electric cars by knocking down straw men and employing...
  16. 5 Seconds to Fully Charge the Volt

    Electric Vehicle Batteries & Plug-In Charging
    My effective fill time is 5 seconds. That's way faster and much more convenient than standing in the rain or sleet or snow or cold at a smelly gas station. That 5 seconds is about how long it takes me to plug in my the Volt. Since the car sits most of time (I don't drive 24 hrs. a day), that's...
  17. New Battery Tech = 10X Charge Life of Today's Batteries

    Electric Vehicle Batteries & Plug-In Charging
    "We have found a way to extend a new lithium-ion battery's charge life by 10 times," said Harold H. Kung, lead author of the paper. http://www.pcmag.com/article2/0,2817,2396398,00.asp?google_editors_picks=true#fbid=3678GJpysuG Just another step on the road to better batteries. It will be...
