Abstract
A radio battery system according to the present invention includes a battery controller and a plurality of cell controllers. The battery controller and the plurality of cell controllers communicate at a plurality of communication slots of a time division communication. The battery controller transmits data at a beginning of each of the plurality of communication slots. Each of the cell controllers measures a state of a cell at one or plurality of predetermined communication slots and transmits data at a predetermined communication slot. Each of the cell controllers is capable of switching between a normal transmission/reception mode and a sleep mode with a low power consumption.
