So I really weird issue with the battery SOC readings today.
Because of the desert heat in Phoenix, I usually keep the charge around 55-60% and run COOLDOWN cycles at night. My RT commute to work is only 7 miles so I don't need much range. I know balancing can be an issue, so I try to do a full standard charge about once a month and my last one was about 15 days ago.
Anyway, this morning, I drove to work as usual. I think the SOC was around 60% when I left. I only worked 1/2 day, so after work, or about 3-1/2 hours later, when I get back in the car the battery level was in red and the SOC reading around 15-20%. I got home and charged at the full 70A. I was, however, only charging between 43 and 53 amps, probably because it was 105 F outside. I let the charge go for about 2-1/2 hours (with a COOLDOWN cycle) the the SOC got back up to 50%. I did see a DMC WARNING Charge Thermal Limit error - probably due to the heat.
I ran an errand and drove 2.2 miles. I was in the store for about 15 minutes and when I get back to the car, the SOC was at 85%.
I called the service center and my car is there now.
Has anyone ever seen an issue like this?
My car was in for annual service 2 weeks ago and got a clean bill of health.
