Last night, in anticipation of a trip today, I changed my max charge fron 90% to 100% and plugged in. About the time I expected the charging to be finished, I received 2 notifications. One from Onstar said charging was interrupted and the other from JuiceNet saying charging was complete. Upon checking the car, the dash charging LED was off. After re-plugging a couple times, charging resumed, adding 2.8kWh (I also saw a small, 3 minute spike after completion, which I attribute to cell balancing?) 2020 Bolt, JuiceBox 32 Next Generation. EDIT: Just read the manual (yeah, I know) it appears I need to check the JuiceBox for audible fault code tones the next time this happens (assuming it's not the car doing the interrupting).
