I have a 2015 Soul EV+ with about 37,500 miles on it. I've been pretty happy with the car for what it is, but have had some issues lately. The OBC failed sometime late last year I think (I don't have my records with me at the moment), and the indicated range noticeably dropped off after that. It has dropped again recently, and I have been regularly seeing 60 to 62 miles on the GOM. Over the weekend, I tried to take a 60ish mile round trip (almost all freeway). Probably averaged about 72MPH on the way out, but stuck to about 65MPH on the way back. By the time we got close to the house, the GOM went to '- - -'. I think I plugged in the car at about 6% SOC as indicated on the center stack display under the battery settings.
I own a eMotorwerks Juicebox smart L2 EVSE that measures and records the kWh it sends back into the car. I installed it about 4 months ago (after the OBC failure - I was using the L1 cordset before). The Juicebox reported that it when it charged the vehicle (to 100% as reported on my car) it only put in 19.3 kWh and it took 2 hours and 51 minutes to do so. I didn't check the power going back in to the car during the charge, but every time I've looked at it on the Juicebox app, the EVSE is usually supplying about 6.8kW. So, it would seem that the accounting/sensor setup on the EVSE is relatively accurate.
I called Folsom Lake Kia and brought the car in. They told me they plugged into the car later that day and it showed 78% state of charge (which is low for merely traveling 10 miles from 100% SOC) and 100% SOH. They performed a BMS firmware update which reset the GOM, so it showed 93 miles when I picked the vehicle up yesterday. I drove the car to work and back home later that day. I then took it out later that night to drain it almost all the way down, so I could measure how much would go back in after the BMS update. The GOM went to '- - -' at about 6 miles and 10% SOC. I continued to drive the car until the turtle light on the dash illuminated, which came on at about 5% SOC as shown by the center stack screen. I pulled into the garage and plugged in. When I woke up this morning, I checked the Juicebox app to see how much energy had been put back in. It says 20.1 kWh and 3 hours and 23 minutes to full charge (which also includes some automatic climate preconditioning, so its probably more like 3 hours). It seems like if the battery has actually degraded that much, I'm close to a warranty replacement. The 20.1kWh from the EVSE also includes parasitic losses through the OBC and other systems, so the actually input back into the battery is probably a bit less.
I've seen a few threads indicating that some people have had some similar issues, but I'm not sure if anyone else has had any input from Kia yet? Has anyone had a similar problem and the BMS still shows a high SOH value? Is there someone at Kia that I can contact to go above the dealer for faster resolution? I don't think the dealership techs are knowledgeable enough yet to handle this sort of thing if it has to do with improper SOC estimation or energy accounting across the modules. Anyone have anything else that they think I can look at/due to figure this thing out? I really wish I had access to the GDS system I used to work with at my old job (I used to work in a battery test lab).
