摘要
Single battery failure will change other batteries＇ load in a power battery pack. Based on the cumulative failure probability equality principle, this paper considers the relationship between the load and the battery life distribution, and constructs a reliability model for the parallel subsystem of the battery pack when a single battery fails, and then compares the lifetime and reliability as a function of load and cell design. The result proves that the k-out-of-n system approaches closed to the parallel subsystem of the power battery pack.
