I set my overnight charging to be done during off peak hours whenever I can. I have mine set to start charging at midnight with the car planned to be charged to the designated amount before 07:00 hrs, when off peak finishes. Up until last night, the car would always start charging at the designated 12:00 midnight and complete sometime thereafter. However, last night the car started charging at 5:40 am and completed at 6:10 am to the designated set point of 70% on this occasion. Only this one sample, so will be interesting to see if that repeats. Has anyone else noticed this behaviour? What do you see of the plusses and minuses of this scenario, should this become the default behaviour? See attached doc of recorded times when my car charges. I think you can easily see the period of charge on the graphs. The shaded area shows when peak electricity starts. (The 24th was off-peak all day of course).
