On Saturday I used one of the Chargepoint systems at the Alewife MBTA station. Chargepoint sent an email at 2:59pm that the charge was complete. When I unplugged the car at 4:54pm, I immediately got the OnStar text and email indicating that the charge was complete. In other words, the car waited until it was unplugged to send the notifications.

I thought, well, ok, maybe something weird about that Chargepoint system. That night I plugged in at home. At 8:29pm, my Clipper Creek charger sent me an email and text that the charge was complete. But I didn't get the notices from OnStar until I unplugged the car this morning. They came immediately.

Anyone else notice this weird behavior?

I guess it depends on how a particular ChargePoint system is configured. I usually go back to my Volt before the first 2 hour of free charging is up. And when I tap the card on the station, it sends me text message right away that my cost of charging is $0.00 for 7 kWH sent by ChargePoint.

Chargepoint worked as expected. It's the Volt that is not.

I've gotten some charge complete text messages hours after I unplugged, drove to work, and depleted the battery. Onstar isn't exactly a world-class system, otherwise I would have renewed instead of letting it lapse (I'm now on the basic plan).

So sadly, this is normal behavior for Onstar.

With the basic plan, most of the time, OnStar App works with Text Messaging. I usually check the charging status using my App because it takes me about 30 minutes to walk back to the charging station from our house. So I always check the status to make sure I have a 30-minute head start, and the app works quite nicely.

Aside from the times when OnStar goes down (which appears to be about once a week at this rate), I get charge notifications as soon as the car finishes charging. I charged at Midway Airport a couple weeks ago and ChargePoint texted me right when I landed at my destination, and OnStar about 20 minutes later*.

It almost sounds like your OnStar unit is going to sleep prematurely and wakes up when you unplug your car...


*protip: if you're charging at a place that bills per-hour as well as per-kWh, manually end your ChargePoint session with the app when it finishes charging! I got billed $30 for adding about 10 kWh because my session was active for the whole weekend when I thought it would end automatically.

Well, it's back to normal today, because I just got the notification and the car is still plugged in. Maybe the OnStar hamsters had the weekend off.
