Abstract:
1. A cell controller, comprising: a plurality of ICs which are connected in series electrically and which are disposed to correspond respectively to a plurality of unit cell groups each having a plurality of unit cells connected in series electrically; and a plurality of capacity adjusting resistors which are disposed to correspond respectively to the plurality of unit cells and which are connected to a corresponding unit cell when a state of charge of the corresponding unit cell is adjusted, the plurality of ICs respectively having: a plurality of voltage detecting terminals to which respective of positive terminals and negative terminals of a plurality of unit cells constituting a corresponding unit cell group are connected; a plurality of capacity adjusting terminals which are disposed to control conduction and blocking between respective of a plurality of unit cells constituting a corresponding unit cell group and capacity adjusting resistors disposed to correspond to respective of the plurality of unit cells; a signal input terminal for inputting signals; and a signal output terminal for outputting signals, wherein, between a signal output terminal of an IC corresponding to one of two potentially adjacent unit cell groups and a signal input terminal of an IC corresponding to another of the two potentially adjacent unit cell groups, the signal output terminal of an IC corresponding to one of two potentially adjacent unit cell groups and the signal input terminal of an IC corresponding to another of the two potentially adjacent unit cell groups are connected so as to transmit signals, further comprising: a plurality of first capacitors which are connected electrically between respective of positive electrodes and negative electrodes of the plurality of unit cells; and a plurality of second capacitors which are connected electrically between voltage detection terminals corresponding to a positive electrode and a negative electrode of respective of unit cells of the plurality of voltage detection terminals.
