Detect disconnected cells in a battery module. Cells can disconnect due to faulty wiring, corrosion, or physical damage to the cell. To prevent further damage to the battery pack, the battery management system (BMS) must detect the disconnected cells and take appropriate action.

이 예제에서는 배터리 관리 시스템 블록을 사용하여 배터리의 전류와 온도를 모니터링하는 방법을 보여줍니다. 임의의 전류 및 온도 프로파일을 배터리에 적용한 다음, 6시간 동안 시뮬레이션합니다.

Inject faults in battery models during simulations using Simscape™ Battery™ and Simulink™ software. First, you explore the effect of disconnecting a battery cell from the other cells of a parallel assembly inside a battery module. A cell disconnection typically happens due to a weld failure or a failure in the cell current interruption device. Then, you add an internal short-circuit fault to a cell of a parallel assembly inside a battery module. The fault triggers a set of exothermic reactions, known as a thermal runaway. You activate both faults during the simulation by using a timed trigger at a simulation time of 30 seconds.
