I've been looking into EV AC chargers for businesses (basically, any and all AC chargers up to 2 x 22kW). One thing I've noticed is that quite a few chargers look alike, sometimes to the point of just having different stickers.
This raised two questions:
Which companies actually design and manufacture EV AC chargers?
Do other companies add something to existing designs? Or do they put the chargers in a different jacket and then resell them?
Sorry if this is not the right place to ask this question. I wasn't quite sure where else to go to.
