Title: WIRELESS BATTERY SYSTEM
Abstract:
A wireless battery system in which predetermined time slots are assigned to a first cell controller and a second cell controller, wherein the second cell controller detects a first transmission radio wave travelling from the first cell controller to a battery controller, and after the first transmission radio wave is no longer detected by the second cell controller, a second transmission radio wave from the second cell controller is transmitted to the battery controller independently of the time slots assigned to the second cell controller.
