Power-sharing charging system, charging device, and method for controlling the same

摘要

The present disclosure provides a charging system including: at least two charging devices including at least two output units configured to supply connected automobiles with charging power, a first bus electrically connected to the output units and configured to transfer charging power to the output units, and a power processing unit configured to process power, which is supplied from a power source, using a first capacity and supply the first bus with the processed power; and a second bus configured to connect a first bus of a first charging device and a first bus of a second charging device, wherein, when a total capacity of charging power supplied to automobiles connected to the first charging device exceeds the first capacity, a part or all of lacking capacity is supplied via the second bus.

1. A charging system comprising:
a first charging device including at least two first output units each configured to supply automobiles connected thereto with charging power, a first bus electrically connected to the first output units and configured to transfer charging power to the first output units, and a first power processing unit configured to process power from a power source and supply the first bus with the processed power, the first power processing unit has a first capacity; a second charging device including at least two second output units each configured to supply automobiles connected thereto with charging power, a second bus electrically connected to the second output units and configured to transfer charging power to the second output units, and a second power processing unit configured to process power, which is supplied from the power source and supply the second bus with the processed power, the second power processing unit has a second capacity; and a shared bus connecting the first bus of the first charging device and the second bus of the second charging device; wherein when power required to charge automobiles connected to the first output units exceeds the first capacity of the first power processing unit, and power required to charge automobiles connected to the second output unit is less than the second capacity of the second power processing unit, excess power processed by the second power processing unit that is not needed to charge automobiles connected to the second output units is routed to the first output units by way of the shared bus to charge automobiles connected to the first output units.
