The invention discloses a method and application for optimizing alternating current to direct current efficiency of a direct current charger during charging, the direct current charger is provided with a plurality of charging modules, and the actual output power of the started charging modules is controlled to be more than 50% of the rated power by controlling the starting number of the charging modules. The charger efficiency is improved, and the loss is reduced. The method specifically comprises the following steps that S1, a judgment algorithm of the starting number of the charging modules is arranged in a direct current charger; s2, carrying out information interaction between the direct-current charger and the charged vehicle, and uploading the read information of the charged vehicle to a cloud platform; and S3, the control unit of the direct-current charger performs data interaction with the cloud platform, and judges the starting number of the charging modules.

    一种优化直流充电机充电时交流转直流效率的方法及应用,所述直流充电机具有多个充电模块,通过控制充电模块的启动数量,将启动的充电模块的实际输出功率控制在额定功率的50%以上。以提高充电机效率,减小损耗。具体包括以下步骤:S1、将所述充电模块启动数量的判断算法置于直流充电机内;S2、将直流充电机与充电车辆信息交互,并将读取到的充电车辆的信息上传至云平台;S3、直流充电机的控制单元与云平台进行数据交互,并判断充电模块的启动数量。
