Abstract
Disclosed is a battery residual value evaluation system, which includes a measurement unit that measures a voltage and a current of an external battery to generate a voltage signal and a current signal, a resistance calculation unit that generates a resistance value, a resistance change value, and a resistance change rate of the external battery for each of charging and discharging cycles of the external battery based on the voltage signal and the current signal, an external input unit that receives reference ranges from an outside, a determination unit that determines a battery residual value based on whether the resistance value, the resistance change value, and the resistance change rate fall within the reference ranges, respectively, and an output unit that outputs the determination result to the outside.
