ABSTRACT:
In a cognition device for battery residual capacity, battery voltage information and battery ambient temperature information are input to a microprocessor through an A/D converter. In the microprocessor, the voltage information is corrected with load information; the data conforming to the ambient temperature information are read out of the battery discharge characteristic data which are previously stored in memory, and the readout data are compared with the corrected voltage information so that the battery residual capacity can be computed from the result of the above comparison data. In this arrangement, it is therefore possible to accurately recognize battery residual capacity at an arbitrary point in time.
