Claim 0:
1. A circuit for a charging station with multiple charging plugs, comprising a power distribution unit, a control unit, one alternating current (AC)/direct current (DC) unit and at least two DC/DC units, wherein
the AC/DC unit is connected with an input end of each of the DC/DC units via a bus;
an output end of each of the DC/DC units is connected to a corresponding charging plug port via the power distribution unit; and
the control unit is configured to detect an output voltage of each of the DC/DC units, and control the power distribution unit to operate according to the output voltage of each of the DC/DC units and a power requirement of a charging plug port, to cause at least one of the DC/DC units to be connected to the charging plug port to achieve power distribution of the charging plug port,
wherein the power distribution unit comprises at least one of a parallel branch that connects the output ends of the DC/DC units in parallel and a series branch that connects the output ends of the DC/DC units in series, wherein the parallel branch and the series branch each is provided with a controllable switch.
