"Unable to charge" error after successful DC fast charge session

Huh. Ok. I don’t think I’ve seen one (emblazoned like that) on my usual routes.

Yeah it's the style outside of QC, just so you don't mistake it for "leaf killer" ABB.

Ouch! That link is to my local charger, and no I haven’t used it.

I'm not sure if this is a "just me" problem or not, so I'm sharing my experience here to see if others have seen it, too.

My last 2 fast charging sessions (with several trouble-free level 2 charges at home in between) seemed to have an unhappy handshake between the charger and my SE at the end of the session:

• Initiate charging session and charge to desired level without drama.
• Tell the charging station "I'm done", either via app or button on station's screen.
• Confirm on app/station that session is done.
• Press the release button on the charge handle to disengage it.
• SE's charge status LED blinks red and instrument cluster displays "Unable to charge" error message. The error message clears after a drive.

I first experienced this with a recently-installed Francis Energy station. Since it's newer, and a provider I had never used before, I thought perhaps there might be a bug/incompatibility in their handshake to end the session.

Today, I experienced this at an EVgo site that I have used before without problems. Today, however, I used a different charger because the one I usually used was occupied. As I pressed the release button on the charge handle, I noticed my SE's charge status LED was still blinking yellow even though the charger & app indicated the session was done--perhaps I should have hit the unlock button on my key fob first?

Prior to these two sessions, I have had trouble-free fast charging sessions at Electrify America and a couple local ChargePoint stations with much older hardware (off-network due to 3G sunset). Unfortunately, someone finally found out those older ChargePoint stations were serving free charges and turned them off.

I've noticed similar behavior on a Chargepoint CPE 250 charger that I've used a few times now. It's happened under several different events:

• The car or charger automatically stops early the charge for some unknown reason
• I manually stop the charge on the charger's display
• I manually stop the charge on the SE's infotainment display

I don't recall seeing this behavior on EA's or EVgo's Signet chargers, but I've only used those a handful of times so far and am still new to all the workings of my new SE. If I have though, the error message clears once I start driving the car, and it doesn't seem to prevent me from using a DC charger again (though I haven't tried immediately after clearing the error). Never saw any such errors charging via level 2 or level 1 EVSEs.

My turn!
This was the last fast charge I needed to get home.
I was plugged in to a Delta evGo charger. Since I hadn't seen a bed in 36 hours, I set climatise and grabbed some zeds in the passenger seat while it charged.
The dash was showing 99% after I woke, about 15 minutes after the charge completed. I unplugged and saw the error when I started the car. Car is charging fine at home. I will try a DC charger maybe tomorrow.
