Abstract
The power compensating device for battery by this invention comprises a battery 10, a cable 13 that connects this battery 10 to a load 11, a compensating capacitor 12 inserted into the input side of the load 11, a voltage detecting circuit 27 that detects the fluctuation of the input voltage to the load 11, a comparison circuit 28 that compares detected value with referential value, a switching circuit 25 to be controlled by a comparison output, and an auxiliary capacitor 26 connected in parallel, via the switching circuit 25, with the compensating capacitor 12 to sufficiently suppress voltage drop. To this power compensating device it is possible to add a display circuit 29 that displays multistagedly the voltage fluctuation to know visually the effects of voltage fluctuation suppression.
