Wondering if anyone else experiences this oddity. I have charged at about 6 different DC fast chargers in the Midwest, and I believe they are the older Signet models. Always have latest software and always pre-condition, starting usually around 20 % SOC. Life is good till about 40-45%, charging over 100 kWh, then the much described yo-yo, fast then slow charging occurs, bouncing between 40 and 90 kWh. If I am patient, this yo yo eventually stops, and the speed becomes like the charging curves, slowly decreases from ~ 110Kwh as my SOC increases. When it does this, a different sound I think happens, and my temperature on car "thermometer" starts to increase.
Any theories?
There is a brand new EA station in west Omaha that I will experiment with soon
