  1. Understanding SOC

    Software & Programming/Code - Chevy Volt
    I've been digging into the CAN bus trying to read battery state. Here's what I have so far SOC is available as percent ModePID: 22005B. Standard vehicle PID for SOC does not return data. max SOC 84.313728. For the rest of the post, I will instead refer to these as decimals ie. 0.84313728 min...
  2. Maximizing SOC, Gen 2 Version

    Generation 2 Volt (2016-2020)
    I've posted before about my technique for maximizing the state of charge in my 2012 Volt. I repeated the procedure in my 2016 Volt (sorry my wife's). Granted it is rather warm right now, so results will be a little better once winter returns. Here is a recap on my procedure: Only works with...
  3. SOC drops after short stop

    Li-Ion Battery, Charging, Mgmt System - Chevy Volt
    So I have looked to see if anyone else has noticed this same thing. I have a longish commute 62 miles each way, and on average I can get between 45 - 50 mile on the battery. I have noticed on some days when I make a short stop in the morning to grab a drink my range will drop by 5 -7 miles. The...
  4. Battery Degradation Test Results After 74K Miles.

    Chevy Volt General Discussion, News, and Events
    Here is the results of my battery degradation test. Data is collected from my Blink Charger. Problem is I never fully drain my battery, one of the only times this happened and I received a 100% charge was on May 23, 2012. Last June I decided to repeat that and arrived home with 1 mile remaining...
  5. The Ultimate Warmup Procedure for the Volt

    Generation 1 Volt (2011-2015)
    I have found the ultimate warmup technique for heating up the Volt and maximizing the charge of the battery. I've posted before about how I have found a way to get an extra 3-4% out of the battery at L2. I am not going to rehash, my technique. Read the post here...
  6. For Volt drivers looking for more data: New data logger/ app campaign by FleetCarma

    Software & Programming/Code - Chevy Volt
    Check out the new indiegogo campaign by FleetCarma. I received an email from them this morning as I was one of the Volt participants last year when FleetCarma sponsored EV Champion Challenge which the Volt team won. I got addicted to the data logging capability of the the FleetCarma C5 loggers...
  7. Maximizing State Of Charge (SOC)

    Generation 1 Volt (2011-2015)
    There has been a technique that has been used by some here instead of using remote start. Instead, we would turn on the car with it still plugged in (L2) and the car would continue to charge for 15-20 min or so. Make sure all accessories are off (lights, climate control, radio, etc). One...
  8. What happens when the battery is full but you're decelerating in low?

    Generation 1 Volt (2011-2015)
    I've been watching a number of things going on with the Volt 'behind the scenes' with my nifty DashDAQ. Jetjock gets the honors for finding it first and he and Rusty get the honors for blazing the trail. There so much to discover that I'm overwhelmed with data but it's been fun. I live on a...
