Fan runs during charging

Drive a V 90 T8 since March 2019. I’m actually satisfied. 2 things bother me. But I don’t know if it’s nirmal or an individual error. 1) Although I choose the “Pure mode” directly, the petrol driver always starts with it. The 2, more annoying: When charging in the carport over 220 volts at the normal shoe socket always jumps again, quite long and an annoying fan for the neighbors. Is that normal?
