I came home last night and was surprised to get the message

"Home Charging Limit Expired"

It is the Location Based setting for the 12 Ampere versus the 8 Ampere portable cord charging. Since I bought my Volt, I bought an adapter to our NEMA 14-50 240V outlet in our garage and have been plugging into 240V using the OEM EVSE that came with the Volt. My Volt charging has been programmed to use the Off-Peak times of our TOU Rates. So for about 6 months now, I've been charging on 240V from the garage or the 208V from public charging stations, and the 110V from our office. In other words, I have never charged at 110V from our home. So that's why I got that message. Nonetheless, I went to settings and reconfigured it back to charge at 12A for the 110V when the portable cord is plugged in at 110V. Plugging the portable cord to the NEMA 14-50 240V outlet thinks that it is plugged into a charging station at home.

Is there a way to set the 12A charging at our office instead? The problem that I could see when I change the Office as Home location, is that I would lose the settings for TOU charging at home and it isn't pretty configuring the schedules for charging with off-peak, mid-peak and peak rates for weekdays and weekends!

Damn, even I am confused. Imagine how the Volt feels! :)

Joe, other Gen2 owners have posted that the charging at 12a by Home location expires every (?) mos. From your post, I can't tell if you realize this or not. Did you try to charge at L2 after the message -- were you not able to automatically at 12a? I don't believe the EVSE defaults to 8a when plugged into 240v; if that is a bad assumption, I'm sure somebody will correct me. I would have only thought the message related to L1 charging.

Assuming my understanding is correct, you could charge at L2 at home using only TOU settings and let the location-based 12a "home" be set for work. Then, at work, you'd override the TOU setting by plugging in twice to start immediately at 12a.

If the EVSE defaults to 8a even when plugged into 240v, then I see your problem.

Location based charging needs to be reset every three months I believe. While you could set your office as your home location, you will lose the ability to define peak/off-peak charging times at your actual home. L2 charging has nothing to do with the 8/12amp setting.

So, the peak/off-peak times can only be set for the home location, and only if the GPS location of HOME is set?

I think you are stuck with manually changing the charge rate from 8 to 12A every time you plug in on 120V when away from home. I am dealing with a similar situation with my Gen 1 every time I charge at home. I have gotten used to the few taps it takes.

Yes. It has become a habit that is now second nature to me. As soon as I push the blue button after arriving at work, I find my finger clicking Charging, then hitting Ok, then hitting 12 Amps, then I get out of the car and plug it in... I can do it half awake since I arrive work at 6 am.

Seems like it is... I haven't tried experimenting with it. You know, it is truly a pain to enter the various charging rates and their schedules from our utility into the very crude interface of the 2nd Gen Volt. I would beat up the programmers who designed the interface! It is the lousiest one ever! And I always scream after I pick up the Chevy Volt from maintenance service as the folks at the service dealership reset all my settings! It means dealing with the user interface again for entering the various schedules and rates. You know, our utility has 2 pages of scheduling of their various rates.

And oftentimes I wouldn't know for sure if the rates and scheduled that I painstakingly enter are correct until the next morning.

I think I would blame the utility not the car.

Seems like it would be much better if there were a place online (myvolt.com for instance) where you could enter, store, update and push those utility rates to your car rather than tapping them in through the touch screen.

I haven't brought in mine for service yet but plan on using the feature to save my settings to a USB stick.
Maybe it will save the TOU schedule as well?

Can the dealer save the settings to a usb stick and then fix the settings before handing the car back to you? Maybe if asked they would?

Could be wrong but I thought you could do it yourself. Not near the car now, but isn't one of the infotainment menu items?
