Abstract
There is provided a wireless battery system reconcilable with unsuccessful communication due to interference from an external wireless instrument or radio wave reflection or shielding under a surrounding physical environment. A wireless battery system allocates a cell controller to a cell, detects a cell state, and wirelessly communicates a cell state detected by a cell controller to a battery controller. During the wireless communication, the battery controller transmits a beacon to the cell controller and specifies a duration for radio wave environment measurement and a frequency to be measured as a condition. The cell controller performs radio wave environment measurement under the specified condition and then returns a measurement result along with the cell state to the battery controller.
