Patent ID: 8426047

Claim:
A multi-series battery control system, comprising: battery cell groups each having a plurality of serially connected battery cells; a plurality of integrated circuits each disposed in correspondence to one of the battery cell groups; and a battery control device that exchanges signals with the integrated circuits, wherein: the integrated circuits are sequentially connected with a transmission path; a signal from the battery control device is received at an integrated circuit assuming a first position with regard to a connection order; the signal is output from the integrated circuit and input to the next integrated circuit in sequence from the integrated circuit assuming the first position to an integrated circuit assuming the last position with regard to the connection order; the signal output from the integrated circuit at the last position is transmitted to the battery control device; in a step assigned with an ordinal number matching the position of the integrated circuit with regard to the connection order, each integrated circuit: receives a message unique to the integrated circuit different from messages sent to other integrated circuits, from the battery control device or the previous integrated circuit; writes over an initialized address of the integrated circuit with the message; alters the message to a message with which an initialized address of another integrated circuit cannot be overwritten; and outputs the altered message to the next integrated circuit if the integrated circuit is not at the last position, or the battery control device if the integrated circuit is at the last position; wherein addresses of the integrated circuits are individually set in sequence as operation in the step is executed sequentially at each of the integrated circuits.
