摘要： A power supply system includes a power distribution branch, a charging branch, and a control unit. The power distribution branch receives a first current. The charging branch includes a charging unit, and the charging branch receives a second current to charge an electric vehicle through the charging unit. The control unit is connected to the charging unit, and receives a current signal of the first current consumed by the power distribution branch. The control unit calculates an adjustment value of the second current according to a variation value of the first current when the first current is varied. A sum of the first current and the second current is less than or equal to an upper-limit value of a total household current. The control unit produces a charging command according to the adjustment value of the second current and provides the charging command to the charging unit.

摘要： An electric vehicle supply equipment receives an external AC power source. The electric vehicle supply equipment includes a relay apparatus and a controller. The relay apparatus has a master relay, an auxiliary relay, and a controllable switch. The master relay is connected to a master power loop. The controllable switch is connected in series to the auxiliary relay to form a series path and connected to an auxiliary power loop. When the controller detects the external AC power source, the controller turns on the auxiliary relay. Afterward, when the controller detects that the external AC power source is in a zero-crossing condition, the controller drives the controllable switch to be turned on. Accordingly, the relays are controlled in coordinated timing, and further the external AC power source is detected, thus implementing the zero-voltage and zero-current turning on of the relay apparatus.
