    • A cell controller with excellent reliability in which noise and soon are suppressed is provided. The cell controller includes, corresponding to the number of cell packs, a plurality of ICs each having a voltage detecting circuit detecting voltages of respective cells of a cell pack in which four cells are connected in series, a switch control circuit controlling conduction and a blocking operation of a plurality of switch elements connected in parallel to the respective cells via capacity adjusting resistors, a LIN1 terminal for inputting control information, a LIN2 terminal for outputting control information, a Vcc terminal and a GND terminal, and a LIN2 terminal of a higher-order IC and a LIN1 terminal of a lower-order IC are connected in a daisy chain. The Vcc terminal of each IC is connected to a positive electrode of a higher-order cell among cells constituting a corresponding cell pack via an inductor L for eliminating noise, and the GND terminal is coupled directly to the Vcc terminal of the lower-order IC. Noise is not superposed on the LIN1, LIN2 terminals.
    • 提供具有良好可靠性的电池控制器,其中噪声很快被抑制。 电池控制器包括对应于电池组数量的多个IC,每个IC具有电压检测电路,该电压检测电路检测其中四个电池串联连接的电池组的各个电池单元的电压,开关控制电路控制导通和阻塞 多个开关元件的操作通过容量调节电阻并联连接到各个单电池,用于输入控制信息的LIN1端子,用于输出控制信息的LIN2端子,Vcc端子和GND端子以及较高的LIN2端子 低阶IC和LIN1端子以菊花链连接。 每个IC的Vcc端子经由用于消除噪声的电感器L连接到构成相应电池组的单电池中的高电压单元的正电极,并且GND端子直接耦合到低位IC的Vcc端子 。 LIN1,LIN2端子不会叠加噪声。
