The invention provides a power supply system of an electric vehicle, a power supply control method and the electric vehicle, and relates to the technical field of vehicles. In a power battery system of the power supply system, two adjacent battery modules are connected through a series switch unit, and two ends of each series switch unit are respectively connected with a positive terminal and a negative terminal through a parallel switch unit; positive terminals and negative terminals in the plurality of power battery packs are respectively connected with a positive input end and a negative input end of the electric driving system; and the charging system is connected with the positive terminal and the negative terminal of each power battery pack, and is also used for being connected with a charging interface of a charging pile. According to the power supply system, by controlling the series-parallel connection relation of the battery modules in each power battery pack, the electric vehicle can be compatible with the charging piles with different voltages during charging, and the power supply system can be matched with any load during discharging.

    本申请提供一种电动汽车的供电系统、供电控制方法及电动汽车,涉及车辆技术领域。该供电系统的动力电池系统中,相邻两个电池模块通过一个串联开关单元连接,每个串联开关单元的两端分别通过一个并联开关单元连接正接线端和负接线端;多个动力电池组中正接线端和负接线端分别连接用电驱动系统的正输入端和负输入端;充电系统连接每个动力电池组的正接线端和负接线端,充电系统还用于连接充电桩的充电接口。本申请的供电系统,能通过控制每个动力电池组中各电池模块的串并联关系,在充电时能使电动汽车兼容不同电压的充电桩,在放电时能使供电系统与任意负载匹配。
