摘要： A vehicle system is provided and includes a modular dynamically allocated capacity storage system (MODACS) and an active management module. The MODACS includes blocks of cells. The active management module is configured to: detect a first state of a first block of cells of the blocks of cells; determine whether a safety fault condition exists with the first block of cells based on the first state of the first block of cells; in response to detecting existence of the safety fault condition, isolate the first block of cells from other ones of the blocks of cells; subsequent to isolating the first block of cells, actively discharge and detect a second state of the first block of cells; and based on the second state, continue isolating the first block of cells or reconnecting the first block of cells such that the first block of cells is no longer isolated.
