The invention provides a charging device, a charging system, an access matching method and a charging method, and relates to the technical field of charging, in the charging device, each power distribution unit is only provided with one voltage detection circuit, and during access matching, each power distribution unit only needs to control one voltage detection circuit to carry out voltage collection on the output end of the power distribution unit; all the power distribution units are simultaneously controlled to sequentially open and close the switch unit of each corresponding charging path, and the power modules are controlled to open and close; according to the invention, simultaneous matching of the corresponding charging paths of all the power distribution units and sequential matching of the charging paths of each power distribution unit can be realized, and software detection logic is simple, so that the problems of complex hardware circuit design, high software implementation difficulty and low operation stability in the existing path matching technology are solved.

    本发明提供了一种充电装置、充电系统及通路匹配方法、充电方法,涉及充电技术领域,本发明中,每个功率分配单元仅设置一个电压检测电路,在进行通路匹配时,每个功率分配单元仅需控制一个电压检测电路对其输出端进行电压采集;并且通过同时控制所有功率分配单元依次对每个对应充电通路的开关单元进行打开与闭合操作,以及控制各个功率模块的开启与关闭,可以实现所有功率分配单元的对应充电通路的同时匹配以及每个功率分配单元的各充电通路依次匹配,软件检测逻辑简单,从而解决了现有通路匹配技术存在的硬件电路设计复杂、软件实现难度大和运行稳定性低的问题。
