Abstract
PURPOSE:To correctly judge an insufficient charging state of a deteriorated state of a battery by defining the battery abnormality when the voltage abnormality is detected in a state excluding an input/output action mode where the power supply voltage drops less than a allowable lower limit level due to the noises. CONSTITUTION:When a voltage detecting circuit 2 detects that the power supply voltage of a battery 1 drops down to a prescribed level, an invalidating means 4 validates or invalidates the output of the circuit 2 based on an active or inactive state of an input/output part discriminated by a discriminating means 3. Thus it is possible to prevent the generation of the undesired power supply alarms due to the voltage fluctuation caused by the noises, etc. In such a way, an insufficient charging state or a deteriorated state of the battery is correctly judged.
