The invention provides a charging method and a charging system for a power battery of an electric vehicle and the electric vehicle, and belongs to the field of electric vehicles. The charging method for the power battery of the electric vehicle comprises the steps that when the voltage of a first charging port of the electric vehicle is lower than that of the power battery, a first battery pack of the power battery and the first charging port are controlled to form a first charging loop, and a second battery pack of the power battery and the first charging port are controlled to form a second charging loop, the power battery at least comprises a first battery pack and a second battery pack. According to the invention, the first battery pack and the second battery pack are respectively connected with the first charging port to form the first charging loop and the second charging loop which are charged in parallel, so that the charging voltage input by the power battery is increased.

    本发明提供电动汽车动力电池的充电方法及充电系统、电动汽车,属于电动汽车领域。所述电动汽车动力电池的充电方法包括:在电动汽车的第一充电口的电压低于动力电池的电压时,控制所述动力电池的第一电池包与第一充电口形成第一充电回路,控制所述动力电池的第二电池包与第一充电口形成第二充电回路,所述动力电池至少包括第一电池包和第二电池包。本发明通过将第一电池包和第二电池包分别与第一充电口连接,形成并联充电的第一充电回路以及第二充电回路,以提升动力电池输入的充电电压。
