<p>A battery monitor system for monitoring the residual capacity of a battery has a controller for determining the residual capacity of a battery, detecting the output electric energy of the battery when the battery is discharged, and correcting the residual capacity depending on the output electric energy such that as the output electric energy of the battery increases, a new residual capacity produced when the residual capacity is corrected decreases. The residual capacity may be corrected by subtracting a residual capacity corrective value which increases as the output electric energy of the battery increases, from the residual capacity. The residual capacity of the battery can accurately be determined and monitored depending on the output electric energy from the battery. In the case where the battery monitor system has a residual capacity display unit and is combined with an electric vehicle, the driver of the electric vehicle can visually recognize the residual capacity of the battery depending on the running condition of the electric vehicle. <IMAGE></p> |
