The invention provides an interconnected charging device, which comprises a plurality of power modules and a controller; the plurality of power modules are electrically connected with one another through contactors, and the contactors are electrically connected with the controller; each power module comprises at least three power units electrically connected with the charging terminal. According to the technical scheme, through the interconnection technology, the power units can achieve the functions of in-device distribution and out-device distribution, interconnection of the power units of multiple sets of equipment or the whole charging station is achieved, the utilization rate of the power units is increased, the maximum output power of a single piece of equipment is increased, and theidle rate of the power units is reduced. And meanwhile, the capacity increase required by the high-power electric vehicle in the later period is reduced to meet the requirement transformation of quick charging.

    本发明提供了一种互联互通的充电装置,其包括多个功率模块和控制器,多个功率模块相互之间分别通过接触器电连接,所述接触器与控制器电连接;每个功率模块包括至少三个与充电终端电连接的功率单元。本发明的技术方案通过互联互通技术,可以使功率单元实现装置内分配和外分配的功能,使多套设备或者整个充电场站的功率单元实现互联互通,提高了功率单元的利用率,并提高了单台设备的最大输出功率,降低了功率单元的闲置率,同时减少后期因为出现大功率的电动汽车而需要增容满足快充的需求改造。
