I snapped the first image the day before we went away for the winter. I wanted to see how much battery loss there'd be between November 5th and our arrival back in BC. As we have needed to spend two weeks in isolation upon return, we didn't bother removing the car cover until today.
My KONA has a small regular-type car battery that runs the instrument panel and electronics. It is charged during long storage by the main battery pack.
Following the auto's manual, I charged to a complete 100% during our first winter away and I had just a 2% loss during those five months. This time, when we left in November 2020, I decided to leave the car with a lower charge, knowing I'd not come back to a dead vehicle. I rolled to a stop at our parking spot at 87%.
I turned on the ignition today and found a similar situation. As shown below, my car's Bluelink app now has a charge of 85%. One major drawback of Hyundai's Bluelink system is that it remains active for a mere three days. Then, the car stops reporting until the ignition is turned on again. So from around November 9th until today, I couldn't see the statistics. Kimchi sits only 2% less after 23 1/2 weeks of storage. It's all ready to take us 415 km on those stale electrons!
