PROBLEM TO BE SOLVED: To make a common integrated circuit available even if the number of battery cells is different.SOLUTION: A plurality of integrated circuits includes a low-order side integrated circuit connected with the battery cells on the low voltage side in a plurality of battery cells connected in series, and monitoring their cell voltages, and a high-order side integrated circuit connected with the high voltage side battery cells in a plurality of battery cells connected in series, and monitoring their cell voltages. The number of battery cells for connection with the low-order side integrated circuit is set to an even number, when the starting point to connect the voltage detection pin on the low voltage side of the low-order side integrated circuit, and the starting point to connect the voltage detection pin on the low voltage side of the high-order side integrated circuit are on the same side of a pair of substrate connections, otherwise the number of battery cells for connection with the low-order side integrated circuit is set to an odd number.
【課題】異なる電池セル数であっても共通の集積回路を利用可能とする。【解決手段】複数の集積回路は、直列に接続された複数の電池セルの内で低電圧側の電池セルに接続されて、これらのセル電圧を監視する下位側集積回路と、直列に接続された複数の電池セルの内で高電圧側の電池セルに接続されて、これらのセル電圧を監視する上位側集積回路とを含む。下位側集積回路の、低電圧側の電圧検出ピンを接続する起点と、上位側集積回路の、低電圧側の電圧検出ピンを接続する起点とが、一対の基板接続部の同じ側である場合は、下位側集積回路に接続する電池セルのセル数を偶数として、下位側集積回路の、低電圧側の電圧検出ピンを接続する起点と、上位側集積回路の、低電圧側の電圧検出ピンを接続する起点とが、一対の基板接続部の異なる側である場合は、下位側集積回路に接続する電池セルのセル数を奇数とする。【選択図】図3
