Cell controller, battery module and power supply system |
摘要 |
A cell control ler with excellent reliability in which noise and so on 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 Lermlnal 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 noi se, 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. |
