1. A method of charging an electric vehicle (EV), the method comprising:
receiving a voltage from an electric power supply over a dedicated circuit at an EV charging system comprising a printed circuit board (PCB) comprising:
a higher voltage side that is operable to receive an alternating current (AC) charging current delivered over a dedicated circuit from an AC power supply; and
a lower voltage side operable to power a processor that controls charging of the EV charging system, wherein the processor receives power from a lower voltage power supply that is separate from the AC power supply and that is not powered by the AC power supply, and wherein a voltage from the lower voltage power supply is less than a voltage from the AC power supply,
wherein the EV charging system is coupled to a plurality of output cables, each output cable coupled to at least one head of a plurality of heads, and wherein the plurality of heads are connectable concurrently to a plurality of EVs; and
delivering charging current to said plurality of EVs connected to the heads, wherein said delivering comprises directing charging current to only one of the output cables at a time if multiple EVs are concurrently connected to EV charging system via the heads by providing the charging current to a first one of the output cables, then stopping the charging current, and switching the charging current to a second one of the output cables, and restarting.
