A first controller can be coupled to a main power supply and deliver a first charging current to an electric vehicle (EV) at a first charging station. The first controller can also deliver power to a second controller that can provide a second charging current to an EV at a second charging station. The first controller turns off the power to the second controller in response to determining that there is an EV charging at the first charging station, and turns on the power to the second controller only in response to determining that an EV is not charging at the first charging station.
