| 摘要 |
In the present invention, a battery system is provided with a battery module in which a plurality of assembled batteries each having a plurality of battery cells are connected, battery monitoring circuits that are provided so as to correspond to each of the assembled batteries of the battery module and monitor the status of each battery cell of the assembled batteries, a control circuit for controlling the operations of the battery monitoring circuits, a first signal transmission path for transmitting signals that are input and output between the battery monitoring circuits and the control circuit, a first isolation element connected to the control circuit, and a second isolation element connected to the battery monitoring circuit. The first signal transmission path is isolated from the control circuit by the first isolation element and is isolated from the battery monitoring circuit by the second isolation element. The electrical potential of the first signal transmission path is a floating potential in relation to the control circuit potential and battery monitoring circuit potential. |
