PROBLEM TO BE SOLVED: To provide a battery system control device capable of controlling current supply with a general load divided into a dark-current necessary load and a dark-current unnecessary load while miniaturizing the device.SOLUTION: An electrical load is disposed while divided into a dark current necessary load L1a requiring supply of dark current from a main battery B1 under an off-state of an ignition switch provided to a vehicle, a dark current unnecessary load L1b non-requiring supply of dark current from the main battery under an off-state, and a stabilization load L2 supplied with a stabilized voltage from a sub-battery B2. An opening/closing switch is configured by a first opening/closing switch SW1 for switching conduction and cutoff between the dark current necessary load and the dark current unnecessary load, and a second opening/closing switch SW2 for switching conduction and cutoff between the dark current unnecessary load and the stabilization load, and the first opening/closing switch and the second opening/closing switch are electrically connected in series between the main battery and sub-battery.SELECTED DRAWING: Figure 1 |
