I have a Tesla and often listen both when the car is charging and not charging. I don't hear a single bit of difference either way. Honestly, there are a lot of other potential noise sources but a charging car is not really one of them.
Electric cars will ruin late night listening?
My system sounds best late at night. I run passive conditioners. Everyone is a sleep, no one is running stoves, microwaves, A/C is running less, the transformers are working less. 5,10,20 years from now we all have electric cars. Everyone is fast a sleep with there electric cars plugged in for there 4 to 8 hour charge every night in my neighborhood,, my city, my state. What will this do to the sonics of our system or the quality of the power coming into our homes?
