摘要：The battery pack monitoring apparatus is for monitoring a battery pack constituted of battery blocks connected in series and each including battery cells connected in series. The battery pack monitoring apparatus includes a cell monitoring circuits provided respectively for the battery blocks, and a control circuit. Each of the cell monitoring circuits includes a cell voltage detection circuit to detect cell voltages of the battery cells included in a corresponding one of the battery blocks, and a block voltage detection circuit to detect a block voltage of the corresponding one of the battery blocks. The control circuit is configured to detect states of the battery cells based on the cell voltages and the block voltages transmitted from the respective cell monitoring circuits.
