CHARGING POST
Document Type and Number:
WIPO Patent Application WO/2018/054378
Kind Code:
A1
Abstract:
A charging post (300) comprises: a power system and a charging terminal; the power system comprises a first power unit, a second power unit, a power control unit, and a heat sink; the first power unit and the second power unit are connected, and the output voltage and output current of the first power unit and the second power unit are same, the power control unit is used for controlling the output voltage and the output current of the two power units; the charging terminal comprises: a charging control module, a direct-current power distribution unit and a charging gun; the charging gun is used for connecting and charging the battery to be charged , the direct-current power distribution unit is used for distributing power supply for the charging gun, and the charging control module is used for billing and displaying the charging. By means of the flexible connection of the two power units, the present application provides the battery to be charged with flexible and variable charging voltage and charging current, thereby overcoming the problem that it is difficult to expand the capacity for the current charging post, and meeting the increasing demand of an electric vehicle for the charging voltage and charging current.
