Description

一种直流充电堆柔性动态功率分配装置
技术领域
本实用新型涉及一种新能源电动车辆充电装置。
背景技术
目前市场上通用的直流充电堆功率分配方法是：把几个充电模块输出合成一组，在每组充电模块输出端串联相应的直流接触器，从而实现每一条母线上功率分配，输出到相应的充电枪口，由于受到体积、接线、成本等诸多因数制约，很难实现单个充电模块功率负荷分配，一般功率负荷分配路数不大于5路，具体如附图1所示。如是，它就具有如下缺陷：
一、由于不能单充电模块功率分配，使得很难在充电中实现充电枪口功率和车辆需求功率很好匹配；
二、由于直流接触器价格比较贵，并且对外接线有控制线和输出线，使得接线多、成本高；
三、由于受到体积、接线、成本等诸多因数制约，不宜使用在直流充电堆路数大于5路的功率分配。
因而如欲克服上述缺陷进行改进就必须设计新的功率分配方案及装置，我们发明在每个充电模块的输出端配置一块功率分配模块单元，该功率分配模块单元为1进2-N出模式（N>=16），通过板载磁保持继电器控制输出至对应母线，从而实现每一条母线上功率分配，输出到相应的充电枪口，通过功率分配单元模块与监控板通讯，可实现单台或多台电动汽车同时充电时柔性动态功率分配，功率分配板配置如图3所示。
