Abstract

PURPOSE:To vary the timing of warning signal output according to a discharging current and to prolong the service life of a storage battery deice by comparing a reference voltage from a variable reference voltage generating circuit with the voltage of the storage battery and outputting a warning signal. CONSTITUTION:In the storage battery device, a warning circuit which outputs the warning signal when the storage battery voltage drops consists of the variable reference voltage generating circuit 10 which detects the storage battery discharging current and outputs the reference voltage based upon the discharging current and a comparing circuit 11 which compares the reference voltage from the circuit 10 with the storage battery voltage and outputs the warning signal when the storage battery voltage drops below the reference voltage. Then, when the storage battery voltage is detected, a set value is varied according to the necessary remaining capacity of the storage battery until the operation end of a load. Consequently, the storage battery voltage and discharging current are inputted to the device at all times and the reference voltage which varies with the discharging current is compared with the storage battery voltage, so the timing of warning output is variable according to the storage battery discharging current.
