The invention relates to a battery system, a vehicle and a control method thereof. The battery system comprises a battery pack assembly, a second switch, a voltage converter and a third switch, the battery pack assembly comprises at least two battery packs connected in series, each battery pack comprises a battery unit and a first switch for short-circuiting the battery unit, a first end of the second switch is connected with a first end of the battery pack assembly, and a second end of the voltage converter is connected with a second end of the battery pack assembly. The second end of the second switch and the second end of the third switch form the first output end of the battery system, the first input end of the voltage converter is connected with the first end of the second switch, and the second input end of the voltage converter is connected with the second end of the battery pack assembly to form the second output end of the battery system. According to the battery pack assembly, the first end of the third switch is connected with the first output end of the voltage converter, and by arranging the voltage converter, when the output voltage is reduced due to the fact that a fault battery pack is removed from the battery pack assembly, discharging can be conducted after voltage boosting through the voltage converter.
本公开涉及一种电池系统、车辆及其控制方法。所述电池系统包括:电池包组件、第二开关、电压变换器以及第三开关,电池包组件包括至少两个串联的电池包,每个电池包包括电池单元和用于短路电池单元的第一开关,第二开关的第一端与电池包组件的第一端连接,第二开关的第二端与第三开关的第二端形成电池系统的第一输出端,电压变换器的第一输入端与第二开关的第一端连接,电压变换器的第二输入端与电池包组件的第二端连接形成电池系统的第二输出端,第三开关的第一端与电压变换器的第一输出端连接,本申请通过设置电压变换器,在电池包组件剔除故障电池包导致输出电压降低时,能够通过电压变换器升压后进行放电。
