A couple of days ago I got to use the new (and currently only) DC fast charger in Dallas. Using it was pretty simple. I pulled near the charger with 3 bars left. When connected, the charger indicated a 41% SOC remaining in the battery (which makes sense when you add the hidden ~15-20% after the bars are gone). The charger charged the car to 91% and did an auto shutoff just like it should.
The gauge problem occured when I got back into the car. At a 91% SOC I was expecting maybe 2 bars depleted at most (maybe one if lucky), but the car showed a full 3 bars depleted, which I seriously doubt was correct, the top 3 bars shoudn't hold 9% total charge. Secondly the "charge time" on the small display in the center showed both times as zero (for 120 and 240), which we know is completely wrong with a 91% SOC AND three (supposed) bars depleted.
Cycling through the different menus did not result in a different reading for the bars or the estimated time to recharge. Turning the car on and off again did nothing as well. I decided to then just take my drive home and hopefully something will work out. After driving for a bit, I noticed I hadn't depleted a bar yet, odd seeming how long I had already driven, but I didn't think anything of it. Then I got onto the tollway bring myself up to highway speeds (65 here) and still nothing. I was starting to think the gauge had been broken so I started flooring it, pushing the car up to 80+ and accelerating and passing people like a bat out of hell, knowing this would probably show some effect soon. It took me 15 minutes of driving aggressively to finally get a bar to drop off the range. This would now total about 30 minutes of total driving, which should have had an effect a long time ago. Once I lost the bar, the charging times popped back on, showing the correct charging times (2 hours 240 and I can't remember the 120).
So why did the car think it was full when estimating the charging times, I had full regen, so it obviously knew the battery was not at 100% SOC. And why did the "fuel gauge" show as it did. From the experience there was at least one additional bar above that was not displayed (no way I could have driven as a I did and only burn one bar). Has anyone else experience this quirk after a DC charge?
