<P>PROBLEM TO BE SOLVED: To provide a battery monitoring device which can reduce costs by decreasing the number of insulation elements. <P>SOLUTION: A battery monitoring device is installed in each of a plurality of blocks into which a battery is divided. The battery monitoring device comprises: voltage detection circuits for detecting voltage of battery cells belonging to the block; a management circuit which belongs to a low voltage power system compared to a power system of the voltage detection circuits, and manages voltage detection data of each battery cell detected by the voltage detection circuit; a communication mode converter which belongs to the same power system as the voltage detection circuits, is connected with the voltage detection circuits by first communication lines for communicating in a clock synchronized communication mode, and is connected with the management circuit by second communication lines for communicating in a clock asynchronized communication mode; and insulation elements which are interposed on the second communication lines between the management circuit and the communication mode converter, respectively. The communication mode converter transmits the pieces of voltage detection data received from the respective voltage detection circuits via the first communication lines to the management circuit via the second communication lines. <P>COPYRIGHT: (C)2013,JPO&INPIT |
