摘要:
A suppressed noise cell controller includes, corresponding to a 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, terminal LIN1 for inputting control information, terminal LIN2 for outputting control information, terminal Vcc and GND terminal, and terminal LIN2 of a higher-order IC and terminal LIN1 of a lower-order IC are daisy chain connected. 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 a noise eliminating inductor, and the GND terminal is coupled directly to Vcc of the lower-order IC. Noise isn't superposed on LIN1 or LIN2.
