Abstract
A battery type determination system includes an electric circuit connected to a battery, and a battery type determination device that determines a type of the battery on the basis of a characteristic value of the electric circuit. The electric circuit includes an AC power supply having a variable frequency, and a capacitor circuit. The battery type determination device includes a resonance state detection unit that detects at least one resonance state in response to an AC signal output from the AC power supply, a resonance frequency detection unit that detects a resonance frequency in the resonance state, a resonance characteristic detection unit that uses the resonance frequency as a resonance characteristic of the battery, and a determination unit that determines whether or not the battery is of the same type as a reference battery by comparing the resonance characteristic of the battery with a reference resonance characteristic of the reference battery serving as a reference for the battery.
