The invention provides a power supply system and a work vehicle. The power supply system comprises a positive electrode port; a negative electrode port; at least two power supply branches which are connected between the positive electrode port and the negative electrode port and are connected in parallel, and at least two switch assemblies which are arranged on the at least two power supply branches in a one-to-one correspondence mode, wherein the control device controls the corresponding switch assembly in the at least two switch assemblies to be switched off according to the operation stateof any one of the at least two power supply branches. A faulty power supply branch can be removed from a power supply system; the power supply system continues to supply power to an electric vehicle through a remaining power supply branch in the non-fault state, the power supply stability of the power battery system is greatly improved, and the situation that the whole power supply system cannot continue high-voltage power supply when one power supply branch in the power supply system is damaged is avoided.
本发明提出了一种供电系统和一种作业车辆。其中,供电系统包括:正极端口;负极端口;至少两个供电支路,至少两个供电支路连接于正极端口和负极端口之间,至少两个供电支路相互并联;至少两个开关组件,至少两个开关组件一一对应设置在至少两个供电支路上,控制装置,控制装置根据至少两个供电支路中任一供电支路的运行状态,控制至少两个开关组件中相对应的开关组件断开。实现可将故障的供电支路从供电系统中剔除,供电系统通过剩余的处于非故障状态的供电支路对电动车辆继续供电,大大提升了动力电池系统供电的稳定性,避免了供电系统中一个供电支路损坏则供电系统整体无法继续高压供电的情况。
