摘要： A cell controller capable of ensuring high safety even when a short occurs among voltage detecting lines without causing increased costs is provided. The cell controller 10 includes a unit cell voltage detecting section 7 to detect a voltage of each unit cell 1 constituting a battery group through each voltage detecting line and a SOC adjusting circuit for adjusting a SOC of each unit cell 1 having resistors 2 for SOC adjustment, switching elements 6, and a bypass control section 8 to exercise on/off control on the switching elements 6. Each resistor 2 is connected in series to each voltage detecting line and the unit cell voltage detecting section 7 to detect a voltage of each unit cell 1 through each of the resistors 2. The bypass control section 8 lets the switching elements 6 corresponding to the unit cells 1 to be SOC-adjusted enter an ON state at a time of adjusting a SOC, and control is exercised so that each resistor 2 for SOC adjustment is connected in series to each voltage detecting line led from each positive and negative electrode of each unit cell 1 to be adjusted and each of the serially connected resistors 2 is connected in parallel to each unit cell 1 to be adjusted.
