Understanding key engineering concepts will pay off in the long run for you, so I made this video to break down AC charging with simple animations.
I have written vehicle-side firmware for AC charging, built three electric cars and drove many miles in them. This is a practical guide to AC charging.
This video is part of the charging series, if you care about AC slow charging, you probably want to check out other charging content I made where I go over different topics.
If you want to know how your charger detects your car there is a separate video just on the PWM waveform and it's duty cycle.
