The invention relates to a reconfigurable battery pack switch control method with a short-circuit risk immunity function. The method comprises the following steps: S1, acquiring a simplest path tableand a short-circuit path table through an offline design; and S2, according to the simplest path table and the short-circuit path table which are finally formed through the offline design, carrying out on-line control on a switch of a reconfigurable battery pack. The short-circuit path table can be determined according to the generalized connection matrix, so that the short circuit of a single battery unit is avoided, and the short circuit after series connection of multiple battery units is avoided. According to the method, the simplest path table is determined through the generalized connection matrix, and the working state of the reconfiguration switch can be determined only by determining the working voltage of the load. According to the invention, the short-circuit risk of the reconfigurable battery pack is effectively avoided, and the actual application of the reconfigurable battery pack can be promoted.

    本发明涉及一种免疫短路风险的可重构电池组开关控制方法,所述方法包括以下步骤:S1:通过离线设计获得最简路径表、短路路径表;S2:根据离线设计最终形成的最简路径表和短路路径表,对可重构电池组的开关进行在线控制。本发明能够根据广义连接矩阵确定短路路径表,避免单个电池单元短路,避免多个电池单元串联后短路。本发明所述方法通过广义连接矩阵确定最简路径表,只需要确定负载的工作电压,即可确定重构开关的工作状态。本发明有效避免了可重构电池组的短路风险,将有助于推动可重构电池组的实际应用。
