Does anyone have any figures for production of harmonics in power lines due to charging electric vehicles and specifically the Tesla? I'm thinking that there is essentially a high current SMPS involved but when charging off a 240v supply the neutral conductor should have little to no current. But that's the trick. Similarly if you are charging off 120v @ 15A the neutral must be involved. Unlike a computer where only a small portion of the power capacity is being used, the EV will want to use nearly all the power capacity.
