Battery monitoring system, signal transmission method, and semiconductor device for monitoring batteries
A battery monitoring system includes a plurality of battery monitoring devices connected in series, such that each battery monitoring device is in communication with at least one adjacent battery monitoring device, and each battery monitoring device monitors battery cells. First and second interface devices are located along first and second communication paths including the battery monitoring devices. A controller controls the first and second interface devices to switch transmission modes between transmitting along the first communication path via the first interface device and the battery monitoring devices, transmitting along the second communication path via the second interface device and the battery monitoring devices, and transmitting along a third transmission mode in which a direction of the communication signals outputted from the first interface device and the second interface device to the plurality of battery monitoring devices are reversed.
