The invention discloses a power battery system for an automobile, which comprises a power battery module, a controllable connection module and a control module, the power battery module comprises a plurality of battery monomers, the controllable connection module comprises a plurality of controllable switches, and any controllable switch is connected with the corresponding battery monomer to form a second output circuit. The control module is used for determining at least one target monomer in a first working state and controlling the on-off of the controllable connection module according to the target monomer, and the target monomer is a specific battery monomer in all the battery monomers. Partial discharging of the power battery module can be achieved, the power battery module can give consideration to discharging power supply in the whole vehicle power-off state and the whole vehicle starting state, hardware modules such as a starting battery do not need to be arranged outside the power battery module, and therefore the use cost and the maintenance cost can be reduced. The invention is widely applied to the technical field of automobiles.

    本发明公开了一种用于汽车的动力电池系统,包括动力电池模块、可控连接模块和控制模块,动力电池模块包括多个电池单体,可控连接模块包括多个可控开关,任一可控开关连接相应电池单体,形成第二输出电路,控制模块用于在第一工作状态下,确定至少一个目标单体,根据目标单体控制可控连接模块的通断,其中,目标单体为全部电池单体中的特定电池单体。本发明可以实现动力电池模块的部分放电,可以由动力电池模块兼顾整车断电状态和整车启动状态下的放电供电,无需在动力电池模块之外设置启动电池等硬件模块,从而有利于降低使用成本和维护成本。本发明广泛应用于汽车技术领域。
