Title: CHARGING PILE SYSTEM
Abstract:
A charging pile system, comprising: a system input bus (110), a plurality of charging pile module groups (130), a power allocation unit (150), and a plurality of charging terminals (170) corresponding to the plurality of charging pile module groups (130); the system input bus (110) is connected with the input ends of the plurality of charging pile module groups (130); the output ends of the plurality of charging pile module groups (130) are connected with the input ends of the plurality of charging terminals (170) by means of the power allocation unit (150); the power allocation unit (150) comprises a first switch group (151), a second switch group (153), a third switch group (155) and a controller (157); each switch group comprises a plurality of switching devices; the controller (157) is used for controlling the plurality of switching devices to flexibly configure, in a serial connection or parallel connection mode and by means of combinations of the plurality of switching devices, the plurality of charging pile module groups (130) to the charging terminals (170) having a power demand greater than that of the corresponding charging pile module groups (130). The charging pile system can effectively increase the range of the output voltage and current output to the each charging terminal.
