The invention relates to the technical field of circuit protection, and provides a battery branch switching method and device and an operation machine.The method comprises the steps that system information of a multi-branch battery system is obtained, and the system information comprises the total number of battery branches in the multi-branch battery system and the operation number of running battery branches; the branch information of each battery branch is acquired; acquiring a branch switching strategy corresponding to the system information under the condition of determining that the multi-branch battery system meets a branch switching condition based on the system information; and based on the branch switching strategy, controlling the on-off of any one or more of the first electric control device, the second electric control device and the power supply power control device so as to switch the battery branch. The method is used for overcoming the defect that safety accidents are caused due to the fact that the multi-branch battery system is not analyzed in the prior art, and safe and stable operation of the multi-branch battery system is achieved.

    本发明涉及电路保护技术领域,提供一种电池支路切换方法、装置及作业机械,方法包括:获取多支路电池系统的系统信息,其中,系统信息包括:多支路电池系统中电池支路的总条数,正在运行的电池支路的运行条数,以及每条电池支路的支路信息;在基于系统信息,确定多支路电池系统满足支路切换条件的情况下,获取与系统信息对应的支路切换策略;基于支路切换策略,控制第一电控制器件、第二电控制器件和电源功率控制器件中任一项或多项的通断,以进行电池支路的切换。本发明用以解决现有技术中未对多支路电池系统进行分析,导致安全事故发生的缺陷,实现多支路电池系统的安全稳定运行。
